Re Central Landfill RIFS Progress Report No 39 Work Period July to August 1991

Dear Ms Serowik

This letter serves as the 39th progress report prepared by GZA GeoEnvironmental Inc (GZA) associated with activities completed to date on the Central Landfill Remedial InvestigationFeasibility Study (RIFS) This progress report has been prepared in accordance with the provision of Section 620 of the February 1985 Work Plan prepared by GZA

PROGRESS MADE THIS REPORTING PERIOD

100 DATA VALIDATION

Roy F Weston has completed the validation of the Phase II analytical data and has submitted a data validation report to the RISWMC GZA has obtained a copy of the final data validation report and is presently incorporating the results of the validation into the Central Landfill analytical data base

As described in a previous progress report (No 36) validation of all Phase I analytical data is complete with the exception of the inner landfill wells While GZA has final analytical data reports we do not have available to us the support documentation from RIAL needed to complete data validation

200 DATA MANAGEMENT

GZA has continued to enter analytical test data into our data management system (Groundwater DMS) We anticipate that all Phase I data will be entered and verified by September 1991 and we are presently entering the more recent quarterly groundwater data The scope of this project is greater than anticipated it has been made difficult by the varying reporting formats by the numerous analytical laboratories who have provided testing support over the years

The following major topics were discussed and a consensus reached

bull DNAPL in Borehole MW91-ML7 - The observed presence of a dense non-aqueous phase liquid (DNAPL) in borehole MW91-ML7 was discussed It was determined by all parties that this issue needed immediate attention and that a small scale pump testrecovery study would be performed as discussed below It was also agreed to that additional deep drilling in the vicinity of the former hazardous waste disposal area (HWDA) would not be prudent given the potential for further migration of DNAPL


bull MW91-ML9 - In light of the observed presence of DNAPL in the HWDA all parties agreed to the need for an additional deep multi-level well along Lineament No 2 (identified by the Fracture Trace Analysis report) to the west of the landfill A general location for this well in the vicinity of existing well WE87-10 and Lineament No 2 was selected This location was chosen based on concerns about encountering additional DNAPL in the HWDA and access constraints due the landfill mound and cap location

It was determined that a geophysical survey would be performed in this area in an attempt to chose the optimal location for the well The EPA indicated that if a geophysical survey were not performed prior to drilling and there was a question as to whether the borehole encountered Lineament No 2 they would require that additional holes be drilled in this area The EPA also indicated however that if a location were selected based on a geophysical survey of the area one borehole may be sufficient pending the results of groundwater analysis from the location A geophysical survey has been performed in this area as discussed below and a location for MW91-ML9 has been recommended based on the results of the survey

A decision was also made to end RI field activities and proceed with the feasibility study if no DNAPL or evidence of DNAPL was observed at location MW91-ML9

bull Draft Remedial Investigation (RD Report - December 20 1991 has been selected as the due date for RISWMCs submittal of a draft RI report to the EPA All parties are aware that due to time constraints the analytical results for testing performed at proposed borehole MW91-ML9 will be in draft format

bull Feasibility Study (FS^ Schedule - RISWMC personnel indicated that a consultant had as yet not been selected to perform the FS due to contractual and procurement issues RISWMC also indicated that they would select a FS contractor within six to eight weeks

400 DNAPL STUDY

In accordance with our August 2 1991 Addendum GZA GeoEnvironmental Inc (GZA) completed a limited DNAPL (dense non-aqueous phase liquid) study in boreholes MW91shyML6 MW91-ML7 and MW91-ML8 The following is a summary of activities completed during this study

In June of 1991 GZA initiated drilling of three boreholes designated MW91-ML6 MW91shyML7 and MW91-ML8 for the installation of several deep multi-level monitoring wells in the vicinity of the former hazardous waste disposal area at the Central Landfill (CLF) in Johnston Rhode Island It was anticipated that these three boreholes would be drilled to depths of 200 300 and 400 feet respectively However due to the observed presence


of a DNAPL layer in borehole MW91-ML7 the drilling program was terminated for further evaluation and the three boreholes were actually completed to depths of 200 91 and 99 feet respectively

Observed DNAPL thicknesses in borehole MW91-ML7 measured from non-detectable to approximately two feet following completion of the borehole DNAPL layer thickness measurements recorded at the site are provided on Table 1 It should also be noted that the reported product thickness values are expected to be accurate to +05 feet Initial DNAPL thicknesses were recorded using an ORS electronic water-product interface probe However this instrument became non-functional due to chemical degradation following several measurements and a weighted tape was then used DNAPL thickness measurements were based on an observed black viscous staining on the tape which was lowered to the bottom of the borehole No measurable DNAPL layer has been observed in wells MW91shyML6 or MW91-ML8

GZA completed a limited DNAPL study in the area between July 31 1991 and August 12 1991 This study included multiple extractions of DNAPL from MW91-ML7 via a submersible pump Additionally pumping and monitoring of boreholes MW91-ML6 and MW91-ML8 in a similar manner was performed Product thickness and recovery rates were also to be measured in borehole MW91-ML7 however due to the limited accuracy of DNAPL measurements and the apparent lack of additional DNAPL in-flow to the borehole monitoring of recovery rates and product thicknesses was not possible

A Timco Mfg Inc PVC and Teflon airgas lift pump and a Timco pump controller were used to remove product and water from the bottom of the boreholes Nitrogen gas was used to drive the pump system Pump effluent was collected in 16 ounce clear glass jars and allowed to stand for visual observation of liquid phase separation Recovered fluids were subsequently bulked in a 20-gallon poly-drum placed within a 55-gallon steel drum

GZA personnel began the DNAPL study on July 31 1991 An initial DNAPL layer thickness of 21 feet was measured in borehole MW91-ML7 using the weighted tape Non-detectable DNAPL layer thicknesses were recorded in boreholes MW91-ML6 and MW91-ML8 Following these measurements a submersible pump was used to pump liquids from the base of each borehole The pump intake was set approximately 01 feet above the base of the borehole Approximately 5 gallons of groundwater was pumped from both MW91-ML6 and MW91-ML8 The water appeared to be light brown (silty) in color no DNAPL was observed

Following pumping of these boreholes the pump was set to the base of borehole MW91shyML7 Liquids pumped from this borehole were dark brown to black in color and exhibited strong volatile organic odors Approximately 75 gallons of DNAPL was recovered As pumping continued beyond 75 gallons the liquids turned relatively clear in color and pumping was terminated No DNAPL thickness measurements were made following

oz


pumping The 75 gallons of DNAPL removed from the borehole is in fairly good agreement with a calculated volume of 55 gallons for the 21 foot measured layer thickness within the 8-inch diameter borehole The 2 gallon difference may be the result of partial mixing with ground water during pumping

On August 1 1991 approximately 24 hours following the initial pumping GZA personnel returned to the site to monitor product recovery in borehole MW91-ML7 No measurable DNAPL was observed on the tape lowered to the bottom of the borehole at this time The submersible pump was again used to evacuate approximately 1 gallon of liquid No distinct DNAPL layer was observed however some individual DNAPL globules were recovered by the pump

Pumping was again performed in borehole MW91-ML7 on August 6 and 12 1991 six and twelve days following the initial pumping respectively Field observations on these two dates were the same as on August 1 in that no measurable DNAPL layer thicknesses were observed and no measurable DNAPL was recovered

500 GEOPHYSICAL SURVEY

GZA completed a limited geophysical survey at the Central Landfill in Johnston Rhode Island The survey was used to evaluate subsurface conditions in the area of existing monitoring well WE87-10 and a previously identified fracture system (ie Lineament No 2) using surficial geophysical methods The purpose of the survey was to identify the approximate ground location of Lineament No 2 to aid in the selection of a drilling location for proposed deep multi-level well MW91-ML9 The scope of services included

bull execution of VLF (very low frequency) resistivity and electromagnetic surveys

bull data interpretation and

bull the preparation of this report

510 BACKGROUND

In June of 1991 GZA initiated drilling of three boreholes designated MW91-ML6 MW91shyML7 and MW91-ML8 in the vicinity of the former hazardous waste disposal area at the Central Landfill in Johnston Rhode Island These boreholes were to be subsequently used for the installation of a deep multi-level monitoring well cluster of up to six wells It was anticipated that these three boreholes would be drilled to depths of 200 300 and 400 feet respectively However due to the observed presence of a DNAPL layer in borehole MW91-ML7 the drilling program was terminated for further evaluation The three boreholes were actually completed to depths of 200 91 and 99 feet respectively

GZV


During subsequent meetings with USEPA RISWMC RIDEM and GZA it was concluded that an additional deep multi-level cluster well should be installed The proposed location of this well designated MW91-ML9 was approximately determined to the southwest of the former hazardous waste disposal area along Lineament No 2 in the vicinity of existing well WE87-10 This location was selected based on concerns over providing potential pathways for the downward migration DNAPL by drilling to greater depths in the HWDA Lineament No 2 was identified and described in a 1987 report entitled Fracture TraceGeophysical Investigation of Central Landfill Site Johnston Rhode Island by Dr John J Fisher Dr Reinhard K Frohlich and Dr Daniel W Urish all of the University of Rhode Island Data presented in this report show several northeast-southwest (NE-SW) trending fractures traversing the CLF site including Lineament No 2 which passes through the HWDA

According to this report Lineament No2 is the second most prominent NE-SW trending fracture trace through the site It was mapped as 12000 feet in length and having prominent fracture trace features which include aligned drainage (20) linear streams (15) elongated lakes (10) linear terrain (10) and swamps and wetlands (5) It is also prominent on SLAR and 1975 aerial photographs and in bedrock at the 295 and 195 interchange

520 SITE DESCRIPTION

The geophysical study area (site) is located approximately 2600 feet southwest of the former hazardous waste disposal area and 600 feet southwest of the base of the landfill The site location is shown on Figure 1 detailed site features are shown in Figure 2 Its location was chosen to be along Lineament No 2 and proximate to the former disposal area while avoiding excessive fill (up to 150 feet thick) and closed landfill areas which are covered by an HOPE landfill cap material

The topography of the study area is relatively flat sloping gently to the northwest Locally however there are moderate to steeply sloping embankments along two stream channels which cross the area Bedrock outcrops are largely evident in the southern half of the site These outcrops resulted from mining of the overlying sand and gravel deposits for use as cover material at the landfill The central portion of the site is characterized by a flat plateau area which averages approximately 3 to 8 feet above the northern and southern bordering areas The area is vegetated by high grass A road constructed from rip-rap rock material also crosses the central portion of the site

Two streams flow through the study area (see Figure No 2) The southern stream receives runoff from elevated areas south of the study area and flows westerly to a large pond located approximately 100 feet southwest of the site The northern stream Cedar Swamp Brook accepts drainage from the pond as well as much of the northwestern and southeastern areas of the CLF property and flows in an easterly direction



The following paragraphs describe the methodology of the geophysical surveys conducted and interpretation of the data collected

531 Methodology

On August 7 and 81991 GZA conducted a multi-phased geophysical survey across the area identified as Lineament No 2 in the vicinity of monitoring well WE87-10 The purpose of this study was to locally map fractured areas associated with Lineament No 2 and based on the results determine an optimal location for drilling a deep borehole in this area The geophysical survey included methods known as Very Low Frequency (VLF) electromagnetic resistivity and conventional electromagnetic or EM methodologies

5311 Very Low Frequency Method

The VLF geophysical method can be used to identify steeply dipping structures having large cross-sectional areas that differ in electrical resistance with respect to their surroundings Typically this method is used to locate water-bearing fractures and is particularly well suited for fractures in crystalline rocks An ABEM WADI-VLF detection device was used in the present survey

The WADI-VLF instrument utilizes the principal of electromagnetic induction to identify changes in the conductance beneath a site It uses the magnetic components of the electromagnetic field generated by long-distance radio transmitters in the VLF band These transmitters are large off-site antennas operated by the Department of the Navy located throughout the world and emit powerful very low frequency electromagnetic signals These signals are conducted away from their point of generation via several wave paths (eg direct ground reflected) and can be detected for thousands of miles from their source

When these emitted electromagnetic waves strike a structure having a relatively low electrical resistivity (such as a water-filled bedrock fracture) a secondary electromagnetic field is induced within that body The WADI-VLF device is tuned to the particular frequency for a given transmitting antenna and readings are collected across the site in an attempt to locate these secondary fields caused by resistivity variations within the subsurface

GZA personnel completed four VLF profiles across the study area on August 7 and 8 1991 The location of each profile is shown on Figure No 2 Each profile was located perpendicular to the strike of Lineament No 2 and measurements were recorded at 25-foot spacings along each line The instrument was tuned to a VLF station operating at 24 Khz located in Cutler Maine This station is located generally northeast of the site

oz


and along the strike of the anticipated fracture system Transmitters located along the strike of the anomalous structures of interest provide optimal induction to produce the secondary electromagnetic fields

In complicated cases unfiltered or raw VLF data can be very difficult to interpret or ascertain the position of individual anomalies Because of this the WADI instrument is designed with an internal data processor which filters the observed data and produces an filtered curve output which can be considered representative of secondary currents in the ground In the filtered output anomalies are shown by the bulges or peaks of the magnetic data which occur directly over the fracture zone The typical effective depth of exploration with the VLF is on the order of 150 feet

Plots of the filtered VLF data obtained and the interpreted anomaly locations are included as Attachment 1 The anomaly locations are also shown in plan view on Figure No 2 and are discussed in Section 500 below

5312 Electromagnetic (EM) Conductivity Survey

An electromagnetic (EM) or ground conductivity survey was completed in the study area on August 8 1991 The EM method is used to map geology by measuring the electrical conductivity of the ground The method is able to sense very small variations of conductivity contrasts and is considered more sensitive to these variations than conventional DC resistivity (ie electrical) resistivity surveys A Geonics EM31 Ground Conductivity Meter was used

The EM method is similar in principal to the VLF method in that electromagnetic signals area used to induce currents into the subsurface thus producing secondary magnetic fields which are sensed by the instrument receiver The magnitude of these resultant secondary magnetic fields are proportional to the ground conductivity The transmitter and receiver units on the Geonics EM31 instrument are located 3 meters apart unlike the VLF method where they are many miles apart The typical effective depth of exploration with the EM31 is on the order of 45 meters (approximately 25 feet)

i

GZA personnel completed three EM profiles across the study area The location of each profile is shown on Figure No 2 Each profile was located perpendicular to the strike of Lineament No 2 and measurements were recorded at 25-foot spacings along each line Plots of the observed EM data obtained and the interpreted anomaly locations are included as Attachment 2 The anomaly locations are also shown in plan view on Figure No 2 and are discussed in Section 500 below

5313 Resistivity Profiles

The resistivity method is used to evaluate the response of the subsurface to the impression of an electrical current The resistance of the ground to the transmission of the electrical energy is measured by placing electrodes into the ground impressing a small current into the ground and measuring the amount of current received at a second set of electrodes placed into the ground some distance from the current electrodes The depth of penetration is dependent upon the distance between the current and receiving electrodes The measured results are reported as apparent resistivities because variable subsurface resistivities beneath the electrode array are averaged the true resistivity would be recorded only if the subsurface was infinitely uniform

On August 8 1991 one resistivity profile was completed along Profile No 1 (see Figure No 2) This profile was conducted to provide data for comparative purpose to the EM data A Wenner electrode array (four equally spaced electrodes) was used with an inter-electrode A spacing of 25 feet The theoretical maximum depth limit for a 25shyfoot spread is approximately 25 feet (the A spacing)

The Wenner electrode array is typically used in conducting horizontal resistivity profiling and is well suited for delineating lateral changes in subsurface apparent resistivities (reciprocal conductivities) Theoretically lateral changes in apparent resistivities result primarily from changes in lithology and pore water resistivities Therefore localized decreases in apparent resistivities (ie increase conductivities) across the study area may be indicative of water-bearing fracture zones An ABEM Terrameter SAS 300 resistivity meter was used to collect the data

A plot of the observed resistivity data is included as Attachment 3 These data are discussed in Section 540 below

540 RESULTS

The following sections describe the results of the geophysical data collected at the site

541 Survey Results and Interpretation

The data plots and interpreted data plots of the VLF survey are provided in Attachment 1 and the interpreted anomalies are shown in plan view on Figure No 2 The cross-hatched areas on Figure No 2 show where the instrument gave a positive or anomalous area of conductivity Also shown are the interpreted fracture location and dip directions for the structures producing these anomalous conductivities The interpreted structures and dip directions were determined using WADI interpretation software stored on the VLF instrument

GZ


In general the magnitude of the observed anomalies are small with maximum Hzr (vertical real magnetic field component) responses ranging from 2 to 5 percent of the total magnetic field Maximum Hzi responses (vertical out-of-phase or imaginary magnetic field component) range from approximately 1 to 25 percent of the total magnetic field In a highly resistive terrain the ratio of in-phase (real) to out-of-phase (imaginary) response is a measure of the targets conductivity Modeled studies (ABEM Interpretation Guide) have shown that rock fractures filled with conductive water (eg salt water) produce imaginary responses that are sometimes on the same order of magnitude as the real phase Freshwater filled fractures yield lower magnitude imaginary-component anomalies

The interpreted VLF data show between 3 to 5 anomalies on each profile The observed anomalies consist of two types vertical fractures and northerly dipping fractures In plan view these fractures appear to lie along preferred NW-SE andor NE-SW strike directions The northwesterly dip direction of these anomalies is consistent with results of the 1986 fracture trace study which showed preferred dip directions in both the northerly and southerly directions The data however do not show one major fracture coinciding with the anticipated strike direction of Lineament No 2 as depicted by points 4 and 5 on Figure No 2

The results of the EM survey are provided in Attachment 2 and are shown in plan view on Figure No 2 These data were used to map lateral conductivity variations only and not to determine structural dip directions Similar to the VLF results the EM data show anomalous conductivities along each of the three profiles The locations of the EM anomalies appear to be in good agreement with the VLF data

Results of the resistivity survey are provided in Attachment 3 and are also shown on Figure No 2 As previously noted resistivity data was collected along Profile OE only The resistivity data show values ranging from approximately 325 to 700 ohm-meters (ohmshym) across the profile with the lowest resistivities (ie lt 450 ohm-m) between locations 20 to 100 feet and 220 to 230 feet respectively

A broad relative low resistivity (ie lt 500 ohm-m) anomaly was detected along the southern end of the profile (stations 15 to 130) Interestingly this low resistivity zone is located in the portion of the site where the expected low resistivity cover material is at a minimum thickness

Resistivity sounding G7 was conducted at a location approximately 600 feet northeast of the present study area in the 1987 fracture trace study The observed apparent resistivities at that location decreased from a maximum of approximately 700 ohm-m at the surface to 224 ohm-m at the maximum electrode spacing (ie maximum depth of


investigation) A resultant model from these data showed subsurface resistivities of 610 ohm-m to 10 300 ohm-m to 85 feet 1200 ohm-m to approximately 110 feet and an infinite half-space of 200 ohm-m underlying the sounding location The data from the present study are in general agreement with these previous results

Tne results of the geophysical survey suggest that several parallel fractures occur in the study area This is not unexpected since major lineaments typically consist of numerous en echelon fractures across a relatively narrow horizontal distance The fractures also appear to be trending in a NE-SW direction The majority of the interpreted fractures are located approximately 75 feet southeast of mapped Lineament No 2

542 Proposed Boring Location - MW91-ML9

It is GZAs opinion that the results of the geophysical survey are somewhat inconclusive in that the magnitude of the anomalies are relatively small and many different interpretations of the data are possible None of the evident data interpretations yield an anomaly with a strike consistent to that of mapped Lineament No 2 Not withstanding GZA has selected a preferred drilling location based on the geophysical data obtained during this study GZAs recommended location to install the proposed deep multi-level well MW91-ML9 is along Profile OE roughly between stations 170N and 185N as shown on Figure No 2

VLF data across this interval shows a relatively narrow large amplitude Hzr and Hzi response The instrument modeled response of this anomaly indicates the presence of a northerly dipping fracture between stations 166 and 183 This was the largest (greatest magnitude) VLF anomaly observed during the study The VLF data was weighted more heavily than the EM and resistivity data due to the greater depth penetration of the method (ie 150 feet vs 25 feet) and the recognized superiority of the method to the purposes of this study

The observed EM data also indicated the presence of a conductor in this area Although it was not the largest EM anomaly observed on this profile it was located in an area otherwise characterized by low conductivities The observed resistivity data is similar to the inverse of the conductivity data in that the lower resistivities were observe in this interval although the interval between stations 150 to 200 was generally higher than other areas of the profile

Another factor that was considered in the selection of this location was the alignment of anomalies across one or more profiles As previously noted several anomalies traversed one or more profiles but due to ambiguity one could argue trends in either the NE-SW or NW-SE directions As can be seen in Figure 2 the recommended drilling location lies at an intersection of these two possible trend directions

Re Central Landfill RIFS Progress Report No 39 Work Period July to August 1991

Dear Ms Serowik

This letter serves as the 39th progress report prepared by GZA GeoEnvironmental Inc (GZA) associated with activities completed to date on the Central Landfill Remedial InvestigationFeasibility Study (RIFS) This progress report has been prepared in accordance with the provision of Section 620 of the February 1985 Work Plan prepared by GZA

PROGRESS MADE THIS REPORTING PERIOD

100 DATA VALIDATION

Roy F Weston has completed the validation of the Phase II analytical data and has submitted a data validation report to the RISWMC GZA has obtained a copy of the final data validation report and is presently incorporating the results of the validation into the Central Landfill analytical data base

As described in a previous progress report (No 36) validation of all Phase I analytical data is complete with the exception of the inner landfill wells While GZA has final analytical data reports we do not have available to us the support documentation from RIAL needed to complete data validation

200 DATA MANAGEMENT

GZA has continued to enter analytical test data into our data management system (Groundwater DMS) We anticipate that all Phase I data will be entered and verified by September 1991 and we are presently entering the more recent quarterly groundwater data The scope of this project is greater than anticipated it has been made difficult by the varying reporting formats by the numerous analytical laboratories who have provided testing support over the years
