1 INTRODUCTION AND OBJECTIVES
In May 1995 a Human Health Risk Assessment was performed as part of the Remedial
Investigation (RI) for the Atlas Tack Corporation (Atlas Tack) site in Fairhaven Massachusetts
(EPA 1995a) Risks were developed for current and future workers (commercialindustrial) and
residents EPA I recently requested that WESTON develop human health risk-based concentrations
(HHRBCs) for individuals who may come in contact with upland and marsh soils near the site and
also sediments of the Boys Creek area (EPA 1997a) The approach and methods were outlined in
a draft protocol submitted by WESTON to EPA Region I on 9 April 1997 (EPA 1997b) EPA I
comments on this draft protocol were outlined hi a letter from EPA I on 25 April 1997 (EPA
1997c) WESTON responses to these comments were sent to EPA I on 21 and 22 May 1997
(WESTON 1997d 1997e respectively)
The objectives of this Technical Memorandum are to present the background methods and results
for the calculation of these HHRBCS in the soils and sediments The chemicals evaluated for each
medium were those chemicals of concern originally selected in the RI report (EPA 1995a) Creek
bed sediments are those located in Boys Creek The upland soils are defined as those soils separate
from the wetlands areas The marsh soils are defined as those in the wetlands including the
Commercial and Industrial Debris Dump (CIDD) area but do not include the creek bed sediments
The HHRBCs calculated for soil exposure do not apply to soils hi the building nor to soils
contiguous with the building these soils have been identified as commercialindustrial (CENAE
1997a 1997b)
2 EXPOSURE PATHWAYS OF CONCERN
21 CREEK BED SEDIMENTS
HHRBCs for the chemicals at the Atlas Tack site were based on the adult visitor who may be
exposed to Boys Creek sediments either directly (incidental ingestion and dermal contact) or
indirectly (through shellfish ingestion) These assumption were predicated on the results from the
i
MNHIAN01|G PROJECTS1097102W001REVHHRBOHRBC1017 DOC 1 1CV1797
RI (EPA 1995a) in which sediments data from Boys Creek were evaluated for human health risks
to an older child trespasser and the future adult resident through incidental sediment ingestion
dermal contact with sediment and shellfish ingestion
The RI showed that health risks from ingestion and dermal contact with sediments were
approximately equivalent for the older child trespasser and the future adult resident Lifetime
carcinogenic risks from exposure to all chemicals ranged from 3E-06 (when mean sediment
concentrations were evaluated) to 7E-06 (when maximum sediment concentrations were evaluated)
Hazard indices ranged from approximately 004 (mean) to 01 (maximum) In contrast potential
carcinogenic risks and hazard indices from shellfish ingestion (hard-shelled clams) from the Boys
Creek area were substantially higher than through the direct ingestion and dermal contact pathways
Adult lifetime carcinogenic risks were greater than 1E-03 and hazard indices were in the
approximate range of 40 to 46 Older child trespasser risks were somewhat lower but still
remained relatively higher as compared with the ingestion and dermal contact pathways Organic
chemicals were the primary contributors to health risks
Based on these results sediment HHRBCs from incidental ingestion dermal contact and shellfish
ingestion were calculated for an adult visitor presumed to be a local resident who fishes in Boys
Creek Based on the 1995 RI report (EPA 1995a) it was assumed that the exposure frequency was
32 days per year
22 UPLAND AND MARSH SOILS
In the RI report (EPA 1995a) the soil ingestion and dermal contact pathways were evaluated for
upland soils under several human health exposure scenarios A separate risk evaluation based on
marsh surface soil exposure scenarios was not conducted In this report upland soils and marsh
soils were treated collectively as one location and human health exposure input assumptions were
identical An exposure frequency of 32 days per year was assumed based on those used in the 1995
RI report
MNHLAN01|G PROJECTSV1097102O001REVHHRBCHRBC1017 DOC gt) 1O1797
3 ESTIMATION OF RISK-BASED CONCENTRATIONS
HHRBCs for soils and sediments were calculated by rearranging standard risk equations used in
the Superrund Risk Assessment process (EPA 1989a 1991) Site-specific exposure assumptions
were applied where possible based on the RI report (EPA 1995a) HHRBCs were based on a target
cancer risk level of 1E-06 and a target hazard quotient level of 01 Appropriate toxicity values
were obtained as discussed below in Section 4 HHRBCs for each chemical were first estimated by
individual exposure pathway Total HHRBCs for a given medium based on all exposure pathways
were then calculated using the method of Rosenblatt et al (1982)
31 INGESTION AND DERMAL CONTACT WITH SOILS AND SEDIMENTS
Table 1 presents the HHRBC algorithm and exposure assumptions used for incidental ingestion of
soils (upland and marsh) and sediments (Boys Creek) Exposure assumptions were based on the
those used in the RI report (EPA 1995a) As previously noted for the purposes of this report
upland soils and marsh soils will be treated collectively as one location and human health
exposure input assumptions will be the same HHRBCs calculated for marsh soils using this
approach may be conservative since human exposure to marsh soils may be less frequent than to
upland soils
Table 2 shows the algorithm for estimating HHRBCs through the dermal contact pathway for soils
and sediments Interim chemical-specific dermal absorption factors from soil were provided by
EPA Region I (EPA 1991f) These interim dermal absorption factors are presented in Table 3 It
was assumed in the dermal contact calculations for both soils and sediments that the surface areas
of the hands and the feet would be exposed To obtain the soil contact rate (SCR) shown in the
algorithm in Table 2 the estimated exposed surface area (1800 cm2 EPA 1992) was multiplied
by the soil-to-skin adherence factor (AF) recommended by EPA (1992) This AF represents an
upperbound value Differences in soil HHRBCs based on dermal contact between marsh and
upland soils would be inversely related to the exposure input assumptions (eg exposed skin
surface area) HHRBCs for marsh surface soils could be recalculated by substituting a new
MNHIAN01|G PROJECTS1097102CPV001REVHHRBCHRBC1017CKX -7 KV1797
exposure input assumption into the algorithm in Table 2 Refer to Section 5 for a discussion on
impact to the integrated HHRBCs
32 SEDIMENT HUMAN HEALTH RISK-BASED CONCENTRATIONS BASED ON SHELLFISH INGESTION
HHRBCs for sediments based on shellfish ingestion were calculated from the algorithm shown in
Table 4 It was assumed that the exposure frequency was 32 days per year The fraction ingested
(FI) of contaminated shellfish was assumed to be 100 that is all shellfish ingested as part of the
diet was assumed to come from Boys Creek sediments
Biota-sediment accumulation factors (BSAFs) were determined from empirical data summarized in
the RJ report (Volume 4 EPA 1995a) The BSAF for each chemical of concern for the sediment
pathway was determined by dividing the reported wet weight tissue data by the reported dry weight
sediment concentration for each chemical Hard-shelled clam chemical concentrations were
determined from the highest reported tissue sample at the six locations shown in Appendix H of the
RJ report (Tables H-52 to H-54 Volume 4 EPA 1995a) Sediment data for each chemical were
obtained from sample location SS-812 (Tables H-26 to H-29 Volume 4 EPA 1995a) Table 5
presents the calculated BSAF values The following rules were used in deriving the BSAFs
bull BSAFs were derived for chemicals in which both shellfish and sediment values were available
bull BSAFs were derived for shellfish samples but where the sediment values were nondetects In this case one-half the sample detection limit for the sediment samples was used
bull If chemicals were detected in sediment but not in the shellfish no BSAF was calculated
4 TOXICITY ASSESSMENT
Oral toxicity criteria were obtained from the Integrated Risk Information System (IRIS EPA 1997)
and the Health Effects Assessment Summary Tables (HEAST EPA 1995b Carcinogenic slope
MNHLAN01IGPROJECTS10971020001REVHHRBCHRBC1017DOC A 101797
factors (CSFs) and noncancer reference doses (RfDs) for the chemicals of concern are presented in
Tables 6 and 7 respectively The toxicity equivalency factor (TEF) approach (EPA 1993) was
used to estimate oral CSFs for the carcinogenic polycyclic aromatic hydrocarbons (PAHs) For
estimating dermal toxicity criteria it was assumed that the administered dose was equivalent to the
absorbed dose as recommended by EPA Region I (EPA 1997f)
5 ESTIMATION OF INTEGRATED MEDIUM-SPECIFIC HHRBCS
Medium-specific HHRBCs for each chemical were calculated by integrating the individual
pathway-specific HHRBCs according to standard EPA methodology The algorithm that was used
is based on the method of Rosenblatt et al (1982) shown in Table 8
The impact of changed exposure assumptions which may be proposed by EPA on integrated
HHRBCs between upland and marsh soils can not be predicted with certainty without knowledge
of the intended changes However the integrated goal would likely change the direction
(increase or decrease) and amount of change depending on the degree of change in the input
assumptions for soil ingestion and dermal contact and the relative importance of each pathway
to the medium of exposure (ie soils) Substitution of revised assumptions in the algorithm in
Table 8 will give new integrated HHRBCs

1 INTRODUCTION AND OBJECTIVES
In May 1995 a Human Health Risk Assessment was performed as part of the Remedial
Investigation (RI) for the Atlas Tack Corporation (Atlas Tack) site in Fairhaven Massachusetts
(EPA 1995a) Risks were developed for current and future workers (commercialindustrial) and
residents EPA I recently requested that WESTON develop human health risk-based concentrations
(HHRBCs) for individuals who may come in contact with upland and marsh soils near the site and
also sediments of the Boys Creek area (EPA 1997a) The approach and methods were outlined in
a draft protocol submitted by WESTON to EPA Region I on 9 April 1997 (EPA 1997b) EPA I
comments on this draft protocol were outlined hi a letter from EPA I on 25 April 1997 (EPA
1997c) WESTON responses to these comments were sent to EPA I on 21 and 22 May 1997
(WESTON 1997d 1997e respectively)
The objectives of this Technical Memorandum are to present the background methods and results
for the calculation of these HHRBCS in the soils and sediments The chemicals evaluated for each
medium were those chemicals of concern originally selected in the RI report (EPA 1995a) Creek
bed sediments are those located in Boys Creek The upland soils are defined as those soils separate
from the wetlands areas The marsh soils are defined as those in the wetlands including the
Commercial and Industrial Debris Dump (CIDD) area but do not include the creek bed sediments
The HHRBCs calculated for soil exposure do not apply to soils hi the building nor to soils
contiguous with the building these soils have been identified as commercialindustrial (CENAE
1997a 1997b)
2 EXPOSURE PATHWAYS OF CONCERN
21 CREEK BED SEDIMENTS
HHRBCs for the chemicals at the Atlas Tack site were based on the adult visitor who may be
exposed to Boys Creek sediments either directly (incidental ingestion and dermal contact) or
indirectly (through shellfish ingestion) These assumption were predicated on the results from the
i
MNHIAN01|G PROJECTS1097102W001REVHHRBOHRBC1017 DOC 1 1CV1797
RI (EPA 1995a) in which sediments data from Boys Creek were evaluated for human health risks
to an older child trespasser and the future adult resident through incidental sediment ingestion
dermal contact with sediment and shellfish ingestion
The RI showed that health risks from ingestion and dermal contact with sediments were
approximately equivalent for the older child trespasser and the future adult resident Lifetime
carcinogenic risks from exposure to all chemicals ranged from 3E-06 (when mean sediment
concentrations were evaluated) to 7E-06 (when maximum sediment concentrations were evaluated)
Hazard indices ranged from approximately 004 (mean) to 01 (maximum) In contrast potential
carcinogenic risks and hazard indices from shellfish ingestion (hard-shelled clams) from the Boys
Creek area were substantially higher than through the direct ingestion and dermal contact pathways
Adult lifetime carcinogenic risks were greater than 1E-03 and hazard indices were in the
approximate range of 40 to 46 Older child trespasser risks were somewhat lower but still
remained relatively higher as compared with the ingestion and dermal contact pathways Organic
chemicals were the primary contributors to health risks
Based on these results sediment HHRBCs from incidental ingestion dermal contact and shellfish
ingestion were calculated for an adult visitor presumed to be a local resident who fishes in Boys
Creek Based on the 1995 RI report (EPA 1995a) it was assumed that the exposure frequency was
32 days per year
22 UPLAND AND MARSH SOILS
In the RI report (EPA 1995a) the soil ingestion and dermal contact pathways were evaluated for
upland soils under several human health exposure scenarios A separate risk evaluation based on
marsh surface soil exposure scenarios was not conducted In this report upland soils and marsh
soils were treated collectively as one location and human health exposure input assumptions were
identical An exposure frequency of 32 days per year was assumed based on those used in the 1995
RI report
MNHLAN01|G PROJECTSV1097102O001REVHHRBCHRBC1017 DOC gt) 1O1797
3 ESTIMATION OF RISK-BASED CONCENTRATIONS
HHRBCs for soils and sediments were calculated by rearranging standard risk equations used in
the Superrund Risk Assessment process (EPA 1989a 1991) Site-specific exposure assumptions
were applied where possible based on the RI report (EPA 1995a) HHRBCs were based on a target
cancer risk level of 1E-06 and a target hazard quotient level of 01 Appropriate toxicity values
were obtained as discussed below in Section 4 HHRBCs for each chemical were first estimated by
individual exposure pathway Total HHRBCs for a given medium based on all exposure pathways
were then calculated using the method of Rosenblatt et al (1982)
31 INGESTION AND DERMAL CONTACT WITH SOILS AND SEDIMENTS
Table 1 presents the HHRBC algorithm and exposure assumptions used for incidental ingestion of
soils (upland and marsh) and sediments (Boys Creek) Exposure assumptions were based on the
those used in the RI report (EPA 1995a) As previously noted for the purposes of this report
upland soils and marsh soils will be treated collectively as one location and human health
exposure input assumptions will be the same HHRBCs calculated for marsh soils using this
approach may be conservative since human exposure to marsh soils may be less frequent than to
upland soils
Table 2 shows the algorithm for estimating HHRBCs through the dermal contact pathway for soils
and sediments Interim chemical-specific dermal absorption factors from soil were provided by
EPA Region I (EPA 1991f) These interim dermal absorption factors are presented in Table 3 It
was assumed in the dermal contact calculations for both soils and sediments that the surface areas
of the hands and the feet would be exposed To obtain the soil contact rate (SCR) shown in the
algorithm in Table 2 the estimated exposed surface area (1800 cm2 EPA 1992) was multiplied
by the soil-to-skin adherence factor (AF) recommended by EPA (1992) This AF represents an
upperbound value Differences in soil HHRBCs based on dermal contact between marsh and
upland soils would be inversely related to the exposure input assumptions (eg exposed skin
surface area) HHRBCs for marsh surface soils could be recalculated by substituting a new
MNHIAN01|G PROJECTS1097102CPV001REVHHRBCHRBC1017CKX -7 KV1797
exposure input assumption into the algorithm in Table 2 Refer to Section 5 for a discussion on
impact to the integrated HHRBCs
32 SEDIMENT HUMAN HEALTH RISK-BASED CONCENTRATIONS BASED ON SHELLFISH INGESTION
HHRBCs for sediments based on shellfish ingestion were calculated from the algorithm shown in
Table 4 It was assumed that the exposure frequency was 32 days per year The fraction ingested
(FI) of contaminated shellfish was assumed to be 100 that is all shellfish ingested as part of the
diet was assumed to come from Boys Creek sediments
Biota-sediment accumulation factors (BSAFs) were determined from empirical data summarized in
the RJ report (Volume 4 EPA 1995a) The BSAF for each chemical of concern for the sediment
pathway was determined by dividing the reported wet weight tissue data by the reported dry weight
sediment concentration for each chemical Hard-shelled clam chemical concentrations were
determined from the highest reported tissue sample at the six locations shown in Appendix H of the
RJ report (Tables H-52 to H-54 Volume 4 EPA 1995a) Sediment data for each chemical were
obtained from sample location SS-812 (Tables H-26 to H-29 Volume 4 EPA 1995a) Table 5
presents the calculated BSAF values The following rules were used in deriving the BSAFs
bull BSAFs were derived for chemicals in which both shellfish and sediment values were available
bull BSAFs were derived for shellfish samples but where the sediment values were nondetects In this case one-half the sample detection limit for the sediment samples was used
bull If chemicals were detected in sediment but not in the shellfish no BSAF was calculated
4 TOXICITY ASSESSMENT
Oral toxicity criteria were obtained from the Integrated Risk Information System (IRIS EPA 1997)
and the Health Effects Assessment Summary Tables (HEAST EPA 1995b Carcinogenic slope
MNHLAN01IGPROJECTS10971020001REVHHRBCHRBC1017DOC A 101797
factors (CSFs) and noncancer reference doses (RfDs) for the chemicals of concern are presented in
Tables 6 and 7 respectively The toxicity equivalency factor (TEF) approach (EPA 1993) was
used to estimate oral CSFs for the carcinogenic polycyclic aromatic hydrocarbons (PAHs) For
estimating dermal toxicity criteria it was assumed that the administered dose was equivalent to the
absorbed dose as recommended by EPA Region I (EPA 1997f)
5 ESTIMATION OF INTEGRATED MEDIUM-SPECIFIC HHRBCS
Medium-specific HHRBCs for each chemical were calculated by integrating the individual
pathway-specific HHRBCs according to standard EPA methodology The algorithm that was used
is based on the method of Rosenblatt et al (1982) shown in Table 8
The impact of changed exposure assumptions which may be proposed by EPA on integrated
HHRBCs between upland and marsh soils can not be predicted with certainty without knowledge
of the intended changes However the integrated goal would likely change the direction
(increase or decrease) and amount of change depending on the degree of change in the input
assumptions for soil ingestion and dermal contact and the relative importance of each pathway
to the medium of exposure (ie soils) Substitution of revised assumptions in the algorithm in
Table 8 will give new integrated HHRBCs
6 RESULTS
61 UPLANDMARSH SOILS
Tables 9 and 10 present the HHRBCs for chemicals of concern selected for upland soils at a cancer
risk of 1E-06 and a hazard quotient of 01 respectively Pathway-specific HHRBCs are shown for
each chemical for incidental ingestion dermal contact and the combined pathways Table 11
summarizes the soil HHRBCs for carcinogenic and noncarcinogenic effects For chemicals which
had both carcinogenic and noncancer HHRBCs the lowest HHRBC is footnoted

1 INTRODUCTION AND OBJECTIVES
In May 1995 a Human Health Risk Assessment was performed as part of the Remedial
Investigation (RI) for the Atlas Tack Corporation (Atlas Tack) site in Fairhaven Massachusetts
(EPA 1995a) Risks were developed for current and future workers (commercialindustrial) and
residents EPA I recently requested that WESTON develop human health risk-based concentrations
(HHRBCs) for individuals who may come in contact with upland and marsh soils near the site and
also sediments of the Boys Creek area (EPA 1997a) The approach and methods were outlined in
a draft protocol submitted by WESTON to EPA Region I on 9 April 1997 (EPA 1997b) EPA I
comments on this draft protocol were outlined hi a letter from EPA I on 25 April 1997 (EPA
1997c) WESTON responses to these comments were sent to EPA I on 21 and 22 May 1997
(WESTON 1997d 1997e respectively)
The objectives of this Technical Memorandum are to present the background methods and results
for the calculation of these HHRBCS in the soils and sediments The chemicals evaluated for each
medium were those chemicals of concern originally selected in the RI report (EPA 1995a) Creek
bed sediments are those located in Boys Creek The upland soils are defined as those soils separate
from the wetlands areas The marsh soils are defined as those in the wetlands including the
Commercial and Industrial Debris Dump (CIDD) area but do not include the creek bed sediments
The HHRBCs calculated for soil exposure do not apply to soils hi the building nor to soils
contiguous with the building these soils have been identified as commercialindustrial (CENAE
1997a 1997b)
2 EXPOSURE PATHWAYS OF CONCERN
21 CREEK BED SEDIMENTS
HHRBCs for the chemicals at the Atlas Tack site were based on the adult visitor who may be
exposed to Boys Creek sediments either directly (incidental ingestion and dermal contact) or
indirectly (through shellfish ingestion) These assumption were predicated on the results from the
i
MNHIAN01|G PROJECTS1097102W001REVHHRBOHRBC1017 DOC 1 1CV1797
RI (EPA 1995a) in which sediments data from Boys Creek were evaluated for human health risks
to an older child trespasser and the future adult resident through incidental sediment ingestion
dermal contact with sediment and shellfish ingestion
The RI showed that health risks from ingestion and dermal contact with sediments were
approximately equivalent for the older child trespasser and the future adult resident Lifetime
carcinogenic risks from exposure to all chemicals ranged from 3E-06 (when mean sediment
concentrations were evaluated) to 7E-06 (when maximum sediment concentrations were evaluated)
Hazard indices ranged from approximately 004 (mean) to 01 (maximum) In contrast potential
carcinogenic risks and hazard indices from shellfish ingestion (hard-shelled clams) from the Boys
Creek area were substantially higher than through the direct ingestion and dermal contact pathways
Adult lifetime carcinogenic risks were greater than 1E-03 and hazard indices were in the
approximate range of 40 to 46 Older child trespasser risks were somewhat lower but still
remained relatively higher as compared with the ingestion and dermal contact pathways Organic
chemicals were the primary contributors to health risks
Based on these results sediment HHRBCs from incidental ingestion dermal contact and shellfish
ingestion were calculated for an adult visitor presumed to be a local resident who fishes in Boys
Creek Based on the 1995 RI report (EPA 1995a) it was assumed that the exposure frequency was
32 days per year
22 UPLAND AND MARSH SOILS
In the RI report (EPA 1995a) the soil ingestion and dermal contact pathways were evaluated for
upland soils under several human health exposure scenarios A separate risk evaluation based on
marsh surface soil exposure scenarios was not conducted In this report upland soils and marsh
soils were treated collectively as one location and human health exposure input assumptions were
identical An exposure frequency of 32 days per year was assumed based on those used in the 1995
RI report
MNHLAN01|G PROJECTSV1097102O001REVHHRBCHRBC1017 DOC gt) 1O1797
3 ESTIMATION OF RISK-BASED CONCENTRATIONS
HHRBCs for soils and sediments were calculated by rearranging standard risk equations used in
the Superrund Risk Assessment process (EPA 1989a 1991) Site-specific exposure assumptions
were applied where possible based on the RI report (EPA 1995a) HHRBCs were based on a target
cancer risk level of 1E-06 and a target hazard quotient level of 01 Appropriate toxicity values
were obtained as discussed below in Section 4 HHRBCs for each chemical were first estimated by
individual exposure pathway Total HHRBCs for a given medium based on all exposure pathways
were then calculated using the method of Rosenblatt et al (1982)
31 INGESTION AND DERMAL CONTACT WITH SOILS AND SEDIMENTS
Table 1 presents the HHRBC algorithm and exposure assumptions used for incidental ingestion of
soils (upland and marsh) and sediments (Boys Creek) Exposure assumptions were based on the
those used in the RI report (EPA 1995a) As previously noted for the purposes of this report
upland soils and marsh soils will be treated collectively as one location and human health
exposure input assumptions will be the same HHRBCs calculated for marsh soils using this
approach may be conservative since human exposure to marsh soils may be less frequent than to
upland soils
Table 2 shows the algorithm for estimating HHRBCs through the dermal contact pathway for soils
and sediments Interim chemical-specific dermal absorption factors from soil were provided by
EPA Region I (EPA 1991f) These interim dermal absorption factors are presented in Table 3 It
was assumed in the dermal contact calculations for both soils and sediments that the surface areas
of the hands and the feet would be exposed To obtain the soil contact rate (SCR) shown in the
algorithm in Table 2 the estimated exposed surface area (1800 cm2 EPA 1992) was multiplied
by the soil-to-skin adherence factor (AF) recommended by EPA (1992) This AF represents an
upperbound value Differences in soil HHRBCs based on dermal contact between marsh and
upland soils would be inversely related to the exposure input assumptions (eg exposed skin
surface area) HHRBCs for marsh surface soils could be recalculated by substituting a new
MNHIAN01|G PROJECTS1097102CPV001REVHHRBCHRBC1017CKX -7 KV1797
exposure input assumption into the algorithm in Table 2 Refer to Section 5 for a discussion on
impact to the integrated HHRBCs
32 SEDIMENT HUMAN HEALTH RISK-BASED CONCENTRATIONS BASED ON SHELLFISH INGESTION
HHRBCs for sediments based on shellfish ingestion were calculated from the algorithm shown in
Table 4 It was assumed that the exposure frequency was 32 days per year The fraction ingested
(FI) of contaminated shellfish was assumed to be 100 that is all shellfish ingested as part of the
diet was assumed to come from Boys Creek sediments
Biota-sediment accumulation factors (BSAFs) were determined from empirical data summarized in
the RJ report (Volume 4 EPA 1995a) The BSAF for each chemical of concern for the sediment
pathway was determined by dividing the reported wet weight tissue data by the reported dry weight
sediment concentration for each chemical Hard-shelled clam chemical concentrations were
determined from the highest reported tissue sample at the six locations shown in Appendix H of the
RJ report (Tables H-52 to H-54 Volume 4 EPA 1995a) Sediment data for each chemical were
obtained from sample location SS-812 (Tables H-26 to H-29 Volume 4 EPA 1995a) Table 5
presents the calculated BSAF values The following rules were used in deriving the BSAFs
bull BSAFs were derived for chemicals in which both shellfish and sediment values were available
bull BSAFs were derived for shellfish samples but where the sediment values were nondetects In this case one-half the sample detection limit for the sediment samples was used
bull If chemicals were detected in sediment but not in the shellfish no BSAF was calculated
4 TOXICITY ASSESSMENT
Oral toxicity criteria were obtained from the Integrated Risk Information System (IRIS EPA 1997)
and the Health Effects Assessment Summary Tables (HEAST EPA 1995b Carcinogenic slope
MNHLAN01IGPROJECTS10971020001REVHHRBCHRBC1017DOC A 101797
factors (CSFs) and noncancer reference doses (RfDs) for the chemicals of concern are presented in
Tables 6 and 7 respectively The toxicity equivalency factor (TEF) approach (EPA 1993) was
used to estimate oral CSFs for the carcinogenic polycyclic aromatic hydrocarbons (PAHs) For
estimating dermal toxicity criteria it was assumed that the administered dose was equivalent to the
absorbed dose as recommended by EPA Region I (EPA 1997f)
5 ESTIMATION OF INTEGRATED MEDIUM-SPECIFIC HHRBCS
Medium-specific HHRBCs for each chemical were calculated by integrating the individual
pathway-specific HHRBCs according to standard EPA methodology The algorithm that was used
is based on the method of Rosenblatt et al (1982) shown in Table 8
The impact of changed exposure assumptions which may be proposed by EPA on integrated
HHRBCs between upland and marsh soils can not be predicted with certainty without knowledge
of the intended changes However the integrated goal would likely change the direction
(increase or decrease) and amount of change depending on the degree of change in the input
assumptions for soil ingestion and dermal contact and the relative importance of each pathway
to the medium of exposure (ie soils) Substitution of revised assumptions in the algorithm in
Table 8 will give new integrated HHRBCs

RI (EPA 1995a) in which sediments data from Boys Creek were evaluated for human health risks
to an older child trespasser and the future adult resident through incidental sediment ingestion
dermal contact with sediment and shellfish ingestion
The RI showed that health risks from ingestion and dermal contact with sediments were
approximately equivalent for the older child trespasser and the future adult resident Lifetime
carcinogenic risks from exposure to all chemicals ranged from 3E-06 (when mean sediment
concentrations were evaluated) to 7E-06 (when maximum sediment concentrations were evaluated)
Hazard indices ranged from approximately 004 (mean) to 01 (maximum) In contrast potential
carcinogenic risks and hazard indices from shellfish ingestion (hard-shelled clams) from the Boys
Creek area were substantially higher than through the direct ingestion and dermal contact pathways
Adult lifetime carcinogenic risks were greater than 1E-03 and hazard indices were in the
approximate range of 40 to 46 Older child trespasser risks were somewhat lower but still
remained relatively higher as compared with the ingestion and dermal contact pathways Organic
chemicals were the primary contributors to health risks
Based on these results sediment HHRBCs from incidental ingestion dermal contact and shellfish
ingestion were calculated for an adult visitor presumed to be a local resident who fishes in Boys
Creek Based on the 1995 RI report (EPA 1995a) it was assumed that the exposure frequency was
32 days per year
22 UPLAND AND MARSH SOILS
In the RI report (EPA 1995a) the soil ingestion and dermal contact pathways were evaluated for
upland soils under several human health exposure scenarios A separate risk evaluation based on
marsh surface soil exposure scenarios was not conducted In this report upland soils and marsh
soils were treated collectively as one location and human health exposure input assumptions were
identical An exposure frequency of 32 days per year was assumed based on those used in the 1995
RI report
MNHLAN01|G PROJECTSV1097102O001REVHHRBCHRBC1017 DOC gt) 1O1797
3 ESTIMATION OF RISK-BASED CONCENTRATIONS
HHRBCs for soils and sediments were calculated by rearranging standard risk equations used in
the Superrund Risk Assessment process (EPA 1989a 1991) Site-specific exposure assumptions
were applied where possible based on the RI report (EPA 1995a) HHRBCs were based on a target
cancer risk level of 1E-06 and a target hazard quotient level of 01 Appropriate toxicity values
were obtained as discussed below in Section 4 HHRBCs for each chemical were first estimated by
individual exposure pathway Total HHRBCs for a given medium based on all exposure pathways
were then calculated using the method of Rosenblatt et al (1982)
31 INGESTION AND DERMAL CONTACT WITH SOILS AND SEDIMENTS
Table 1 presents the HHRBC algorithm and exposure assumptions used for incidental ingestion of
soils (upland and marsh) and sediments (Boys Creek) Exposure assumptions were based on the
those used in the RI report (EPA 1995a) As previously noted for the purposes of this report
upland soils and marsh soils will be treated collectively as one location and human health
exposure input assumptions will be the same HHRBCs calculated for marsh soils using this
approach may be conservative since human exposure to marsh soils may be less frequent than to
upland soils
Table 2 shows the algorithm for estimating HHRBCs through the dermal contact pathway for soils
and sediments Interim chemical-specific dermal absorption factors from soil were provided by
EPA Region I (EPA 1991f) These interim dermal absorption factors are presented in Table 3 It
was assumed in the dermal contact calculations for both soils and sediments that the surface areas
of the hands and the feet would be exposed To obtain the soil contact rate (SCR) shown in the
algorithm in Table 2 the estimated exposed surface area (1800 cm2 EPA 1992) was multiplied
by the soil-to-skin adherence factor (AF) recommended by EPA (1992) This AF represents an
upperbound value Differences in soil HHRBCs based on dermal contact between marsh and
upland soils would be inversely related to the exposure input assumptions (eg exposed skin
surface area) HHRBCs for marsh surface soils could be recalculated by substituting a new
MNHIAN01|G PROJECTS1097102CPV001REVHHRBCHRBC1017CKX -7 KV1797
exposure input assumption into the algorithm in Table 2 Refer to Section 5 for a discussion on
impact to the integrated HHRBCs
32 SEDIMENT HUMAN HEALTH RISK-BASED CONCENTRATIONS BASED ON SHELLFISH INGESTION
HHRBCs for sediments based on shellfish ingestion were calculated from the algorithm shown in
Table 4 It was assumed that the exposure frequency was 32 days per year The fraction ingested
(FI) of contaminated shellfish was assumed to be 100 that is all shellfish ingested as part of the
diet was assumed to come from Boys Creek sediments
Biota-sediment accumulation factors (BSAFs) were determined from empirical data summarized in
the RJ report (Volume 4 EPA 1995a) The BSAF for each chemical of concern for the sediment
pathway was determined by dividing the reported wet weight tissue data by the reported dry weight
sediment concentration for each chemical Hard-shelled clam chemical concentrations were
determined from the highest reported tissue sample at the six locations shown in Appendix H of the
RJ report (Tables H-52 to H-54 Volume 4 EPA 1995a) Sediment data for each chemical were
obtained from sample location SS-812 (Tables H-26 to H-29 Volume 4 EPA 1995a) Table 5
presents the calculated BSAF values The following rules were used in deriving the BSAFs
bull BSAFs were derived for chemicals in which both shellfish and sediment values were available
bull BSAFs were derived for shellfish samples but where the sediment values were nondetects In this case one-half the sample detection limit for the sediment samples was used
bull If chemicals were detected in sediment but not in the shellfish no BSAF was calculated
4 TOXICITY ASSESSMENT
Oral toxicity criteria were obtained from the Integrated Risk Information System (IRIS EPA 1997)
and the Health Effects Assessment Summary Tables (HEAST EPA 1995b Carcinogenic slope
MNHLAN01IGPROJECTS10971020001REVHHRBCHRBC1017DOC A 101797
factors (CSFs) and noncancer reference doses (RfDs) for the chemicals of concern are presented in
Tables 6 and 7 respectively The toxicity equivalency factor (TEF) approach (EPA 1993) was
used to estimate oral CSFs for the carcinogenic polycyclic aromatic hydrocarbons (PAHs) For
estimating dermal toxicity criteria it was assumed that the administered dose was equivalent to the
absorbed dose as recommended by EPA Region I (EPA 1997f)
5 ESTIMATION OF INTEGRATED MEDIUM-SPECIFIC HHRBCS
Medium-specific HHRBCs for each chemical were calculated by integrating the individual
pathway-specific HHRBCs according to standard EPA methodology The algorithm that was used
is based on the method of Rosenblatt et al (1982) shown in Table 8
The impact of changed exposure assumptions which may be proposed by EPA on integrated
HHRBCs between upland and marsh soils can not be predicted with certainty without knowledge
of the intended changes However the integrated goal would likely change the direction
(increase or decrease) and amount of change depending on the degree of change in the input
assumptions for soil ingestion and dermal contact and the relative importance of each pathway
to the medium of exposure (ie soils) Substitution of revised assumptions in the algorithm in
Table 8 will give new integrated HHRBCs

3 ESTIMATION OF RISK-BASED CONCENTRATIONS
HHRBCs for soils and sediments were calculated by rearranging standard risk equations used in
the Superrund Risk Assessment process (EPA 1989a 1991) Site-specific exposure assumptions
were applied where possible based on the RI report (EPA 1995a) HHRBCs were based on a target
cancer risk level of 1E-06 and a target hazard quotient level of 01 Appropriate toxicity values
were obtained as discussed below in Section 4 HHRBCs for each chemical were first estimated by
individual exposure pathway Total HHRBCs for a given medium based on all exposure pathways
were then calculated using the method of Rosenblatt et al (1982)
31 INGESTION AND DERMAL CONTACT WITH SOILS AND SEDIMENTS
Table 1 presents the HHRBC algorithm and exposure assumptions used for incidental ingestion of
soils (upland and marsh) and sediments (Boys Creek) Exposure assumptions were based on the
those used in the RI report (EPA 1995a) As previously noted for the purposes of this report
upland soils and marsh soils will be treated collectively as one location and human health
exposure input assumptions will be the same HHRBCs calculated for marsh soils using this
approach may be conservative since human exposure to marsh soils may be less frequent than to
upland soils
Table 2 shows the algorithm for estimating HHRBCs through the dermal contact pathway for soils
and sediments Interim chemical-specific dermal absorption factors from soil were provided by
EPA Region I (EPA 1991f) These interim dermal absorption factors are presented in Table 3 It
was assumed in the dermal contact calculations for both soils and sediments that the surface areas
of the hands and the feet would be exposed To obtain the soil contact rate (SCR) shown in the
algorithm in Table 2 the estimated exposed surface area (1800 cm2 EPA 1992) was multiplied
by the soil-to-skin adherence factor (AF) recommended by EPA (1992) This AF represents an
upperbound value Differences in soil HHRBCs based on dermal contact between marsh and
upland soils would be inversely related to the exposure input assumptions (eg exposed skin
surface area) HHRBCs for marsh surface soils could be recalculated by substituting a new
MNHIAN01|G PROJECTS1097102CPV001REVHHRBCHRBC1017CKX -7 KV1797
exposure input assumption into the algorithm in Table 2 Refer to Section 5 for a discussion on
impact to the integrated HHRBCs
32 SEDIMENT HUMAN HEALTH RISK-BASED CONCENTRATIONS BASED ON SHELLFISH INGESTION
HHRBCs for sediments based on shellfish ingestion were calculated from the algorithm shown in
Table 4 It was assumed that the exposure frequency was 32 days per year The fraction ingested
(FI) of contaminated shellfish was assumed to be 100 that is all shellfish ingested as part of the
diet was assumed to come from Boys Creek sediments
Biota-sediment accumulation factors (BSAFs) were determined from empirical data summarized in
the RJ report (Volume 4 EPA 1995a) The BSAF for each chemical of concern for the sediment
pathway was determined by dividing the reported wet weight tissue data by the reported dry weight
sediment concentration for each chemical Hard-shelled clam chemical concentrations were
determined from the highest reported tissue sample at the six locations shown in Appendix H of the
RJ report (Tables H-52 to H-54 Volume 4 EPA 1995a) Sediment data for each chemical were
obtained from sample location SS-812 (Tables H-26 to H-29 Volume 4 EPA 1995a) Table 5
presents the calculated BSAF values The following rules were used in deriving the BSAFs
bull BSAFs were derived for chemicals in which both shellfish and sediment values were available
bull BSAFs were derived for shellfish samples but where the sediment values were nondetects In this case one-half the sample detection limit for the sediment samples was used
bull If chemicals were detected in sediment but not in the shellfish no BSAF was calculated
4 TOXICITY ASSESSMENT
Oral toxicity criteria were obtained from the Integrated Risk Information System (IRIS EPA 1997)
and the Health Effects Assessment Summary Tables (HEAST EPA 1995b Carcinogenic slope
MNHLAN01IGPROJECTS10971020001REVHHRBCHRBC1017DOC A 101797
factors (CSFs) and noncancer reference doses (RfDs) for the chemicals of concern are presented in
Tables 6 and 7 respectively The toxicity equivalency factor (TEF) approach (EPA 1993) was
used to estimate oral CSFs for the carcinogenic polycyclic aromatic hydrocarbons (PAHs) For
estimating dermal toxicity criteria it was assumed that the administered dose was equivalent to the
absorbed dose as recommended by EPA Region I (EPA 1997f)
5 ESTIMATION OF INTEGRATED MEDIUM-SPECIFIC HHRBCS
Medium-specific HHRBCs for each chemical were calculated by integrating the individual
pathway-specific HHRBCs according to standard EPA methodology The algorithm that was used
is based on the method of Rosenblatt et al (1982) shown in Table 8
The impact of changed exposure assumptions which may be proposed by EPA on integrated
HHRBCs between upland and marsh soils can not be predicted with certainty without knowledge
of the intended changes However the integrated goal would likely change the direction
(increase or decrease) and amount of change depending on the degree of change in the input
assumptions for soil ingestion and dermal contact and the relative importance of each pathway
to the medium of exposure (ie soils) Substitution of revised assumptions in the algorithm in
Table 8 will give new integrated HHRBCs
6 RESULTS

risk of 1E-06 and a hazard quotient of 01 respectively Pathway-specific HHRBCs are shown for
each chemical for incidental ingestion dermal contact and the combined pathways Table 11

exposure input assumption into the algorithm in Table 2 Refer to Section 5 for a discussion on
impact to the integrated HHRBCs
32 SEDIMENT HUMAN HEALTH RISK-BASED CONCENTRATIONS BASED ON SHELLFISH INGESTION
HHRBCs for sediments based on shellfish ingestion were calculated from the algorithm shown in
Table 4 It was assumed that the exposure frequency was 32 days per year The fraction ingested
(FI) of contaminated shellfish was assumed to be 100 that is all shellfish ingested as part of the
diet was assumed to come from Boys Creek sediments
Biota-sediment accumulation factors (BSAFs) were determined from empirical data summarized in
the RJ report (Volume 4 EPA 1995a) The BSAF for each chemical of concern for the sediment
pathway was determined by dividing the reported wet weight tissue data by the reported dry weight
sediment concentration for each chemical Hard-shelled clam chemical concentrations were
determined from the highest reported tissue sample at the six locations shown in Appendix H of the
RJ report (Tables H-52 to H-54 Volume 4 EPA 1995a) Sediment data for each chemical were
obtained from sample location SS-812 (Tables H-26 to H-29 Volume 4 EPA 1995a) Table 5
presents the calculated BSAF values The following rules were used in deriving the BSAFs
bull BSAFs were derived for chemicals in which both shellfish and sediment values were available
bull BSAFs were derived for shellfish samples but where the sediment values were nondetects In this case one-half the sample detection limit for the sediment samples was used
bull If chemicals were detected in sediment but not in the shellfish no BSAF was calculated
4 TOXICITY ASSESSMENT
Oral toxicity criteria were obtained from the Integrated Risk Information System (IRIS EPA 1997)
and the Health Effects Assessment Summary Tables (HEAST EPA 1995b Carcinogenic slope
MNHLAN01IGPROJECTS10971020001REVHHRBCHRBC1017DOC A 101797
factors (CSFs) and noncancer reference doses (RfDs) for the chemicals of concern are presented in
Tables 6 and 7 respectively The toxicity equivalency factor (TEF) approach (EPA 1993) was
used to estimate oral CSFs for the carcinogenic polycyclic aromatic hydrocarbons (PAHs) For
estimating dermal toxicity criteria it was assumed that the administered dose was equivalent to the
absorbed dose as recommended by EPA Region I (EPA 1997f)
5 ESTIMATION OF INTEGRATED MEDIUM-SPECIFIC HHRBCS
Medium-specific HHRBCs for each chemical were calculated by integrating the individual
pathway-specific HHRBCs according to standard EPA methodology The algorithm that was used
is based on the method of Rosenblatt et al (1982) shown in Table 8
The impact of changed exposure assumptions which may be proposed by EPA on integrated
HHRBCs between upland and marsh soils can not be predicted with certainty without knowledge
of the intended changes However the integrated goal would likely change the direction
(increase or decrease) and amount of change depending on the degree of change in the input
assumptions for soil ingestion and dermal contact and the relative importance of each pathway
to the medium of exposure (ie soils) Substitution of revised assumptions in the algorithm in
Table 8 will give new integrated HHRBCs
6 RESULTS
61 UPLANDMARSH SOILS
Tables 9 and 10 present the HHRBCs for chemicals of concern selected for upland soils at a cancer
risk of 1E-06 and a hazard quotient of 01 respectively Pathway-specific HHRBCs are shown for
each chemical for incidental ingestion dermal contact and the combined pathways Table 11
summarizes the soil HHRBCs for carcinogenic and noncarcinogenic effects For chemicals which

combined pathways Table 14 summarizes the sediment HHRBCs for carcinogenic and
noncarcinogenic effects For chemicals which had both carcinogenic and noncancer HHRBCs the

= Noncarcinogenic reference dose (RfD0 mgkg-d)
SCR f= Soil or sediment contact rate (mgday) = Adult sediment exposure (1800 mgday hands and feet) = Adult soil exposure (1800 mgday hands and feet)
RAF = Relative absorption factor (unitless) See Table 3
CF = Soilsediment conversion factor (106 kgmg)
EF = Exposure frequency 32 daysyear
ED = 30 years
The SCR is based on the following assumptions approximately 1800 cm2 of adult skin surface area exposed for feet plus hands (EPA 1992 Dermal Exposure AssessmentmdashPrinciples and Applications) and 1 milligram per square centimeter (mgcrn2) soil to skin adherence factor

factors (CSFs) and noncancer reference doses (RfDs) for the chemicals of concern are presented in
Tables 6 and 7 respectively The toxicity equivalency factor (TEF) approach (EPA 1993) was
used to estimate oral CSFs for the carcinogenic polycyclic aromatic hydrocarbons (PAHs) For
estimating dermal toxicity criteria it was assumed that the administered dose was equivalent to the
absorbed dose as recommended by EPA Region I (EPA 1997f)
5 ESTIMATION OF INTEGRATED MEDIUM-SPECIFIC HHRBCS
Medium-specific HHRBCs for each chemical were calculated by integrating the individual
pathway-specific HHRBCs according to standard EPA methodology The algorithm that was used
is based on the method of Rosenblatt et al (1982) shown in Table 8
The impact of changed exposure assumptions which may be proposed by EPA on integrated
HHRBCs between upland and marsh soils can not be predicted with certainty without knowledge
of the intended changes However the integrated goal would likely change the direction
(increase or decrease) and amount of change depending on the degree of change in the input
assumptions for soil ingestion and dermal contact and the relative importance of each pathway
to the medium of exposure (ie soils) Substitution of revised assumptions in the algorithm in
Table 8 will give new integrated HHRBCs
6 RESULTS
61 UPLANDMARSH SOILS
Tables 9 and 10 present the HHRBCs for chemicals of concern selected for upland soils at a cancer
risk of 1E-06 and a hazard quotient of 01 respectively Pathway-specific HHRBCs are shown for
each chemical for incidental ingestion dermal contact and the combined pathways Table 11
summarizes the soil HHRBCs for carcinogenic and noncarcinogenic effects For chemicals which
had both carcinogenic and noncancer HHRBCs the lowest HHRBC is footnoted

(SCR)(RAF)(CF)(EF)(ED)
Where
RBCdCT = Risk-based concentration in soil or sediment (mgkg) equivalent to target risk level
TR = Target risk (eg carcinogenic = 1E-06 hazard quotient = 1)
BW = Adult body weight (70 kg)
AT = Averaging time cancer (25550 days) noncancer (10950 days)
TC0 = Oral toxicity criteria
= Inverse of carcinogenic slope factor (1 CSF0 mgkg-d)
= Noncarcinogenic reference dose (RfD0 mgkg-d)
SCR f= Soil or sediment contact rate (mgday) = Adult sediment exposure (1800 mgday hands and feet) = Adult soil exposure (1800 mgday hands and feet)
RAF = Relative absorption factor (unitless) See Table 3
CF = Soilsediment conversion factor (106 kgmg)
EF = Exposure frequency 32 daysyear
ED = 30 years
The SCR is based on the following assumptions approximately 1800 cm2 of adult skin surface area exposed for feet plus hands (EPA 1992 Dermal Exposure AssessmentmdashPrinciples and Applications) and 1 milligram per square centimeter (mgcrn2) soil to skin adherence factor
