Dear Mr. Yates:
URS Corporation (URS) is pleased to provide this report describing the Phase II
Environmental Site Investigation (ESI) at the above-referenced property, which is located
within the risk area boundaries of the Carson River Mercury Superfund Site (CRMS). The
Phase II ESI was conducted according to the Sampling and Analysis Plan (SAP), dated
September 27, 2011, and approved by the Nevada Division of Environmental Protection
(NDEP) on September 27, 2011. The SAP was based on the Draft Long-Term Sampling and
Response Plan (LTSRP), dated August 5, 2011, for the CRMS and conversations between
URS and NDEP.
ENVIRONMENTAL ISSUES
A Phase I Environmental Site Assessment (ESA) was prepared for the Site by ATC, dated
November 5, 2010. At the time of the Site reconnaissance, the Site consisted of
approximately 27 acres of generally undeveloped, graded land that contained a 50%
complete model home in the northwestern portion of the Site and two stormwater retention
basins in the southwestern and southeastern portions of the Site. The Site was described as
mostly vacant, desert land with evidence of past grading activities. Paved access roads were
located on the Site.
ATC identified the following recognized environmental condition (REC) associated with the
Site:
Mr. Jack YatesNevada Division of Environmental ProtectionJanuary 11, 2012Page 2
• The Site is located within the risk area of the CRMS, per the NDEP. The NDEPwebsite dedicated to the CRMS depicts a map of the sampling locations, and theclosest data points to the Site are located in Fallon. ATC states that the designation ofwhat is within the CRMS in itself does not mean that the area is impacted, just thatthe potential exists. As a portion of the Site falls within the 100-year flood zone, thatarea of the Site would need to follow the sampling protocol for moderate risk.
According to Mr. Jack Yates, the case officer with the NDEP Bureau of CorrectiveActions, based on the Site’s location within a 100-year flood zone (Zone AE), the Siteis in the CRMS risk area and needs to undergo sampling per the LTSRP.
Mr. Yates provided the Carson River Mercury Superfund LTSRP Risk Assessmentand Management Guidelines to ATC. Based on the information provided by Mr.Yates, portions of the Site are within the risk boundary of the CRMS, which is a RECto the Site.
SCOPE OF WORK
The purpose of the investigation is to evaluate if Contaminants of Concern (CoCs), which
include mercury, arsenic, and lead, related to the CRMS are present on the 138 undeveloped
residential lots and one partially developed lot at the Site at levels which exceed
screening/action levels. One developed lot was present on Site (Lot 14); however, this lot
was identified to be owned by others and was not included in this investigation. There are
other areas of the Site that are not proposed for residential development (Figure 1). The two
stormwater retention basins were not included in this assessment. The LTSRP guidelines are
required to be followed for any future development or construction activities that fall within
the CRMS risk zones.
URS spoke with NDEP on August 31, 2011 to clarify the scope of work required for the Site.
NDEP indicated that the LTSRP had been updated on August 5, 2011. URS discussed the
scope of work proposed for the Site in a subsequent email message, and NDEP confirmed
that the sampling on the moderate risk sites could remain at four soil borings per lot, per the
previous draft of the LTSRP. However, upon review of the Draft SAP for the Site on
September 20, 2011, NDEP advised URS to select lots to sample as moderate risk per the
new LTSRP, which requires 10 soil borings and eight soil samples per lot. The changes to
the low risk lots included collecting five samples from the ground surface to 6 inches in the
front and back portions of each lot (for a total of ten 6-inch deep holes per lot) and analyzing
Mr. Jack YatesNevada Division of Environmental ProtectionJanuary 11, 2012Page 3
two 5-point composite samples for Site CoCs. NDEP also indicated that lots that are mapped
primarily outside of the 100-year flood plain may be designated as low risk.
The approved SAP and letter from the NDEP are presented in Attachment A.
HEALTH AND SAFETY AND GEOGRAPHIC INFORMATION SYSTEMS (GIS)
Prior to mobilizing equipment to the Site, a health and safety plan was prepared and kept on
Site during all field activities in accordance with Code of Federal Regulations (CFR)
Title 29, part 1910.120.
The local public utility identification service was contacted to mark utilities crossing the Site
from the Site boundary to a metering point. URS assumed that utilities had been installed in
the roads that were developed on the Site, but had not been extended onto the 138 vacant lots
on the Site, as no houses had been constructed. However, natural gas and electrical utilities
were marked by Southwest Gas in the front of each lot. As a result of these utilities being
present on Site, URS met with Southwest Gas on October 24, 2011 to conduct a Site walk
and clear the soil boring locations. URS did not advance the borings until these safety
measures had been completed.
URS acquired the lot and parcel information for the Site from the Churchill County Assessor.
URS used Geographic Information System (GIS) to outline the lot boundaries and identify
sampling locations prior to mobilizing to the Site. These locations were programmed into a
Trimble GeoXT Global Positioning System (GPS) unit, with an accuracy of less than 1 meter
horizontally, for use by field personnel. The field team used the GPS to navigate to the soil
boring locations, which were marked in the field prior to the drilling activities. The sampling
locations were pre-designated in the GPS, which including identifying the samples that were
composited for analysis.
The soil borings were named with an A through E for the five borings completed in the front
of each lot and with an F through J for the five borings completed in the back of each lot.
The soil boring locations that were marked with the GPS unit are presented on Figures 2
through 4.
Mr. Jack YatesNevada Division of Environmental ProtectionJanuary 11, 2012Page 4
A construction silt fence for stormwater control, followed by wooded land, was observed on
the lots in the northern portion of the Site. The wooded land extended from the silt fence to
the Carson River. Due to the dense vegetation on the lots, the soil boring locations F through
J in the back of Lots 20, 22, 23, 24, 25, and 84 had to be relocated into areas that were
accessible with either the direct push technology (DPT) drill rig or with a hand auger. In
addition, soil sampling location I on Lot 31 was originally located over soft fill material that
would not support the DPT drill rig. This soil boring was relocated a few feet to the north
towards soil sampling location F. The locations actually sampled were surveyed using the
GPS unit. The final soil boring locations on these lots are presented on Figure 2.
The GIS data that was collected as part of this investigation is included on a CD in
Attachment B.
FIELD IMPLEMENTATION
The LTSRP specified collecting composite samples from specific depth intervals down to
2 feet below grade in moderate risk areas and to 6 inches below grade in low risk areas. The
floodplain sediments were anticipated to potentially include gravel or cobbles, which would
be difficult to penetrate with manual sampling tools. Therefore, the soil borings were
advanced with a DPT drill rig. Any modifications to boring locations were resurveyed with
the GPS, as discussed above.
NDEP provided a map that depicted the Site location relative to the low and moderate risk
areas that are described in the LTSRP. The moderate risk areas corresponded to the extent of
the mapped Federal Emergency Management Agency (FEMA) 100-year flood zone. URS
then used GIS to overlay the proposed lot locations onto the map and determined that
112 lots would be assessed as low-risk and 28 lots would be assessed as moderate-risk,
according to the definition in the LTSRP and based on comments provided by NDEP. The
location of the lots relative to the moderate and low risk areas is presented on Figure 1.
According to the requirements of the LTSRP and subsequent correspondence with NDEP,
two sets of five soil samples each were collected from the ground surface to 6 inches below
ground surface (bgs) on each lot proposed for residential development in areas that are
defined as low risk.
Mr. Jack YatesNevada Division of Environmental ProtectionJanuary 11, 2012Page 5
Two sets of five soil borings were advanced to 2 feet bgs on each lot proposed for residential
development in areas that are defined as moderate risk, five borings in the front of the lot (A
through E) and five borings in the back of the lot (F through J). The soil boring locations on
the low and moderate risk sites are presented on Figures 2 through 4.
Based on the requirements of the LTSRP, URS advanced 280 soil borings on the moderate
risk lots at the Site. Soil samples were collected in 6-inch intervals (0 to 6 inches, 6 inches to
12 inches, 12 inches to 18 inches, and 18 inches to 24 inches) to the total depth of 2 feet bgs,
either with the DPT drill rig or with a hand auger (e.g., several locations in the back of lots
20, 21, 22, 23, 24, and 84). Samples from each discrete depth interval, from the front and
back of the each lot, was composited by the laboratory into two 5-point composite samples
and analyzed (e.g., two 5-point composites from 0 to 6 inches, two 5-point composites from
6 inches to 12 inches, two 5-point composites from 12 inches to 18 inches, and two 5-point
composites from 18 inches to 24 inches). Eight soil samples were submitted for analysis
from each lot, for a total of 224 samples from the moderate risk lots.
On the low risk lots, the LTRSP requires that 10 samples from the ground surface to 6 inches
be collected, five samples each from the front (A through E) and back (F through J) of the
lots. Based on these requirements, URS collected 1,110 samples with a hand auger or trowel.
Lot 14 was not sampled, as originally proposed, as this lot is owned by another party and is
not part of this project. The 10 discrete soil samples from each lot will be composited into
two 5-point composite samples that were submitted for analysis. Two samples were
submitted for analysis from each lot for a total of 222 samples.
A total of 446 soil samples were collected for submittal to the laboratory for analysis from
both the low and moderate risk lots.
Soil cores from the DPT drilling or hand augering on the moderate risk lots were collected
continuously in 6-inch or 2-foot intervals to a maximum depth of 2 feet bgs for the 280 soil
borings on the moderate risk lots. These samples were collected into acetate sleeves, which
were cut in the field by the geologist to the desired 6-inch intervals or soil sampling jars.
During the soil sampling activities, there was no visual or olfactory evidence of impacts
observed.
Mr. Jack YatesNevada Division of Environmental ProtectionJanuary 11, 2012Page 6
The soil materials on Site were generally classified as sand, silt, silty sand, sandy silt, and silt
with minor sand from the ground surface to 2 feet bgs on the moderate risk lots. These
observations were generally consistent across the entire Site (both low and moderate risk
lots). Some of the lots had sparse gravel across the surface, which resulted from prior
grading of the lots at the Site.
On lots 18, 22, 24, and 84, adjacent to the south of the Carson River, and on lots 130 and 155
sand, sand with minor silt, and sandy silt was observed to a depth of approximately 1 to 1.5
feet bgs, which was underlain by slightly moist to moist clayey silt or clay with very fine
sand to the boring termination depths of 5 feet. These observations were made in the soils to
the back of lots 18, 22, 24, and 84, adjacent to the Carson River.
Decontamination and Investigation Derived Waste
All reusable drilling and sampling tools that contacted subsurface materials were
decontaminated between uses as appropriate by washing with a non-phosphate detergent
solution, rinsing with potable water, and air drying.
Soil cuttings were not generated during this investigation, due to the nature of the soil
sampling. The soil borings on the moderate risk lots were sealed with bentonite grout to the
ground surface. The soil borings on the low risk lots were filled with native material present
on Site.
Disposable sampling equipment and personal protective equipment was managed as solid
waste in plastic garbage bags and placed in a receptacle for disposal.
Laboratory Analysis
In accordance with the LTSRP, dated August 5, 2011, all of the samples analyzed were
laboratory sieved to 250 microns (60 mesh) prior to analysis.
The soil samples were analyzed for arsenic, lead, and mercury by Environmental Protection
Agency (EPA) Method 6010B/7471 as specified in the LTSRP. The soil samples were
analyzed by Pace Analytical of Lenexa, Kansas, on standard turnaround.
Mr. Jack YatesNevada Division of Environmental ProtectionJanuary 11, 2012Page 7
URS directed the laboratory to analyze 50 field duplicate soil samples at a frequency of
approximately 10% of the total samples. The duplicate samples were analyzed for quality
assurance (QA)/quality control (QC) to evaluate the validity of the sample results for a total
of 496 samples analyzed.
Based on the data quality evaluation, no systematic problems were detected, and the overall
data objectives for sample contamination, precision, accuracy, and sample integrity were
met. These analytical data are of acceptable quality and may be used for their intended
purposes, with the qualifications noted. The complete laboratory data validation is presented
in Attachment C.
ANALYTICAL RESULTS
URS compared the soil sample results to the CRMS screening/action levels defined in the
LTSRP. The screening/action levels defined for arsenic, lead, and mercury are as follows:
• Arsenic – 32 milligrams per kilogram (mg/kg)
• Lead – 400 mg/kg
• Mercury – 80 mg/kg
The individual lots are identified by the lot number provided by the Churchill County
Assessor. The lots in the southeastern portion of the Site repeated numbers; therefore, a
1 was placed in front of these lot numbers to differentiate them from the other lot of the same
name on the Site. For example, if the lot number is Lot 24 in this area, it is identified on
Table 1 and in the text as Lot 124. The soil analytical results compared to the CRMS
screening/action levels are presented on Table 1. The mercury, arsenic, and lead analytical
results are presented on Figures 5 through 19. The complete analytical laboratory reports are
included as Attachment D.
Moderate Risk Lots
Twenty-eight lots (lots 2, 3, 9 through 12, 18, 20, 22, 24, 28, 31, 40, 44, 64, 71, 76, 82, 84,
102, 107, 121, 126, 130, 135, 138, 148, and 155) on the Site were selected as moderate risk
lots based on their proximity to the Carson River and randomly throughout the Site in the
Mr. Jack YatesNevada Division of Environmental ProtectionJanuary 11, 2012Page 8
FEMA 100-year floodplain. A total of eight 5-point composite samples were analyzed per
lot in discrete 6-inch intervals from the ground surface to 24 inches bgs for a total of 224
samples.
Mercury was detected above the laboratory reporting limits in 211 of the 224 samples
analyzed at concentrations that ranged from 0.043 mg/kg (Lot 126 18-24 Front) to
15.7 mg/kg (Lot 20 18-24 Back). None of the mercury results from the moderate risk lots
exceeded the CRMS screening/action level of 80 mg/kg.
Arsenic was detected above the laboratory reporting limits in all 224 of the samples
analyzed. Concentrations ranged from 4.6 mg/kg (Lot 28 18-24 Front) to 27.6 mg/kg
(Lot 155 12-18 Back). None of the arsenic results from the moderate risk lots exceeded the
CRMS screening/action level of 32 mg/kg.
Lead was detected above the laboratory reporting limits in all 224 of the samples at
concentrations that ranged from 2.7 mg/kg (Lot 28 6-12 Back) to 24.2 mg/kg (Lot 130 12-18
Back). None of the lead results from the moderate risk lots exceeded the CRMS
screening/action level of 400 mg/kg.
The results of the duplicate samples analyzed were comparable to the original sample results,
and none of these results exceeded their respective CRMS action levels.
Low Risk Lots
The remaining 110 lots on the Site were characterized as low risk. Lot 14 is owned by
others; therefore, no sampling was conducted as the lot is not part of the project. These lots
were identified as low risk based on the location of the lots relative to the Carson River 100-
year floodplain and conversations with the NDEP. A total of two 5-point composite samples
were analyzed from each lot for a total of 222 samples analyzed. The discrete samples were
collected from the ground surface to 6 inches bgs as discussed above.
Mercury was detected above the laboratory reporting limit in 221 of the 222 samples
analyzed, and the concentrations ranged from 0.056 mg/kg (Lot 33 Front) to 52.8 mg/kg (Lot
57 Front). None of the mercury results from the low risk lots exceeded the CRMS
screening/action level of 80 mg/kg.
Mr. Jack YatesNevada Division of Environmental ProtectionJanuary 11, 2012Page 9
Arsenic was detected above the laboratory reporting limits in all 222 of the samples
analyzed. Concentrations ranged from 5.2 mg/kg (Lot 25 Front) to 28.5 mg/kg (Lot 57
Front). None of the arsenic results from the low risk lots exceeded the CRMS
screening/action level of 32 mg/kg.
Lead was detected above the laboratory reporting limits in all 222 of the samples analyzed at
concentrations ranging from 3.3 mg/kg (Lot 25 Back) to 18.7 mg/kg (Lot 109 Front). None
of the lead results from the low risk lots exceeded the CRMS screening/action level of
400 mg/kg.
The results of the duplicate samples analyzed were comparable to the original sample results,
and none of these results exceeded their respective CRMS screening/action levels.
SUMMARY
This investigation generally followed the scope of the SAP, dated September 27, 2011, and
approved by the NDEP on September 27, 2011. The SAP was based on the Draft LTSRP,
dated August 5, 2011, for the CRMS and conversations between URS and NDEP.
Deviations from the SAP included relocating several soil boring locations due to the presence
of a construction silt fence for stormwater control, followed by wooded land on the lots in the
northern portion of the Site. The wooded land extended from the silt fence to the Carson
River. Due to the dense vegetation on the lots, the soil boring locations F through J in the
back of Lots 20, 22, 23, 24, 25, and 84 had to be relocated into areas that were accessible
with either the DPT drill rig or with a hand auger. In addition, soil sampling location I on
Lot 31 was originally located over soft fill material that would not support the DPT drill rig.
This soil boring was relocated a few feet to the north towards soil sampling location F. The
locations actually sampled were surveyed using the GPS unit.
URS used GIS to overlay the proposed lot locations onto the Site map and determined that
there were 28 lots to be assessed as moderate risk and 110 lots to be assessed as low risk,
according to the definition in the LTSRP, the location of the lots relative to the 100-year
FEMA floodplain and based on comments provided by NDEP.
Mr. Jack YatesNevada Division of Environmental ProtectionJanuary 11, 2012Page 10
Lots 2, 3, 9 through 12, 18, 20, 22, 24, 28, 31, 40, 44, 64, 71, 76, 82, 84, 102, 107, 121, 126,
130, 135, 138, 148, and 155 were evaluated as moderate risk lots, based on their location
proximal to the Carson River and randomly on Site within the 100-year FEMA floodplain.
Ten soil borings were advanced to 2 feet bgs on each moderate risk lot, five borings each in
the front (A through E) and back (F through J) of the lot. Soil samples from these lots were
collected in 6-inch intervals (0 to 6 inches, 6 inches to 12 inches, 12 inches to 18 inches, and
18 inches to 24 inches) to the total depth of 2 feet bgs. Each discrete depth interval, from the
front and back of the each lot, were composited by the laboratory into two 5-point composite
samples and analyzed (e.g., two 5-point composites from 0 to 6 inches, two 5-point
composites from 6 inches to 12 inches, two 5-point composites from 12 inches to 18 inches,
and two 5-point composites from 18 inches to 24 inches). Eight samples were submitted for
analysis from each lot for a total of 224 samples from the moderate risk lots.
The remaining lots were evaluated as low risk. URS collected 1,110 samples with a hand
auger or trowel on these low risk lots, five from the front (A through E) and five from the
back (F through J) of each lot. The 10 discrete soil samples from each lot were composited
by the laboratory into two 5-point composite samples for analysis for a total of 222 soil
samples analyzed.
No visual or olfactory evidence of impacts was observed in any of the soil borings.
A total of 446 soil samples and 50 field duplicate samples were submitted to the laboratory
for analysis of mercury, arsenic, and lead by EPA Method 6010/7471.
On the moderate risk lots arsenic and lead were detected above the laboratory reporting limits
in all 224 of the soil samples analyzed, and mercury was detected above the laboratory
reporting limits in 211 of the 224 samples analyzed. None of the soil results exceeded the
CRMS screening/action levels of 80 mg/kg for mercury, 32 mg/kg for arsenic, or 400 mg/kg
for lead.
On the low risk lots, mercury was detected above the laboratory reporting limits in 221 of the
222 samples, and arsenic and lead were detected above the laboratory reporting limits in all
222 of the samples analyzed. None of the soil results exceeded the CRMS screening/action
levels of 80 mg/kg for mercury, 32 mg/kg for arsenic, or 400 mg/kg for lead.
