1.0 INTRODUCTION

This report has been prepared by ESS Group, Inc. (ESS) on behalf of Invenergy Thermal Development LLC (Invenergy; the Client) and summarizes the objectives and findings of the focused subsurface investigations (the Investigation) performed on the proposed Clear River Energy Center (CREC) property in Burrillville, Rhode Island (the Property). The investigations were performed in accordance with the Focused Work Plan – A-80 Investigation (dated August 14, 2018; Work Plan) and the Focused Work Plan Supplemental A-80 Investigation (dated September 26, 2018; Supplemental Work Plan), prepared by ESS on behalf of Invenergy, included in Appendix A. These Work Plans were developed in consultation with Natural Resource Services (“NRS”), the consultant retained by the Town of Burrillville (the Town). Figure 1 shows the location of the proposed CREC.

Prior to the initiation of these field activities, notices were provided to theTown by Invenergy. Advance notices of field activities were also provided to NRS by ESS. NRS provided technical oversight on behalf of the Town during the performance of the investigation activities.

The objectives of the initial A-80 Investigation, as noted in the Work Plan, were as follows:

To determine whether the subsurface conditions (i.e., presence/absence of “meaningful” stratified drift), as determined by a certified geologist, along the southwestern boundary of the Property support inclusion of this area within the A-80 Overlay District.

To determine, in conjunction with the findings of the 2015 Geotechnical Investigation performed by GZA GeoEnvironmental, Inc. (GZA, 2015), whether the subsurface conditions are consistent with the subsurface conditions within the remainder of the proposed area of development.

The objectives of the Supplemental A-80 Investigation, as noted in the Supplemental Work Plan, were as follows:

To assess the northern extent of subsurface conditions observed at the Test Pit-2 (TP-2) location.

To evaluate the depth to the water table at the TP-2 location.

The following sections provide further details and discussion on the background, field investigation approach and methodologies, data compilation and analysis, and findings and conclusions.

2.0 BACKGROUND

The Town has established aquifer protection zoning (Section 30-202. – Aquifer Zoning, Burrillville, RI Code of Ordinances) in order to protect these resources. The purposes of the aquifer protection zoning are provided in the ordinance as follows.

In order to protect the water resources of the Town of Burrillville, prevent the development or use of land in the groundwater sources and aquifer area in a manner tending to adversely affect the water quality within the Town of Burrillville, or tending to destroy or have a substantially adverse effect on the environment of the town by virtue of pollution of the land or water by foreign substances including noxious liquids, gases or solid wastes or any potentially harmful conditions which may endanger the health, safety and general welfare of the citizens of the Town of Burrillville. Through use of the following sections, density and uses will be controlled over and around our groundwater sources and aquifer zones;

A-80 Zone Investigation January 7, 2019

To protect, preserve and maintain the quality and supply of groundwater reservoirs upon which the residents of the Town of Burrillville and others depend for drinking water supply;

To protect the quality and supply of water by regulating the use and development of land adjoining wetlands and watercourses which replenish groundwater reservoirs, to protect primary groundwater recharge areas, and to prevent uses of land detrimental thereto; and

To otherwise protect the health, safety and general welfare of the public.

The USGS mapped the extent of stratified drift within the Branch River Basin, which includes the Town (USGS, 1974). The Town’s aquifer protection zoning is based on this extent of stratified drift as mapped by the USGS. The aquifer protection zoning also reportedly takes into consideration public water supply Wellhead Protection Areas mapped by the Rhode Island Department of Environmental Management (RIDEM). Wellhead protection areas are shown on a separate town map from the Aquifer Overlay Zone Map.

Stratified drift is defined as “Unconsolidated sediment that has been sorted by glacial meltwater and deposited in layers, or strata” in the 1974 USGS report.

The aquifer zoning ordinance establishes three overlay districts based on the mapping of stratified drift by the U.S. Geological Survey (USGS, 1974) and ranges of estimated transmissivity (feet/day) as follows:

1. A-80 Overlay District (0-2,500 feet/day)

2. A-100 Overlay District (2,500-5,000 feet day)

3. A-120 Overlay District (5,000+ feet/day)

The ordinance also specifies permitted and prohibited uses within these overlay districts. The ordinance refers to an Aquifer Overlay Zone Map that shows the overlay districts.

Glacial till, the predominant surficial geologic deposit within and in the vicinity of the proposed CREC property, is defined as “Predominantly nonsorted, nonstratified, unconsolidated sediment deposited directly from glaciers” in the 1974 USGS report.

A geotechnical investigation of the Property performed by GZA in 2015 to support the design of the CREC identified the subsurface materials as glacial till over a majority of the Property, consistent with the 1974 USGS report and the surficial geology mapping available through the Rhode Island Geographic Information System (RIGIS).

The CREC property and proposed power-generation facility were designed to avoid the A-80 Overlay District as mapped by the USGS and adopted by the Town. During initial Energy Facility Siting Board (EFSB) hearings, the Town expressed uncertainty as to the mapped extent of the A-80 Aquifer Zone and requested that Invenergy determine the extent of the A-80 Overlay District proximal to the CREC property.

Invenergy prepared the Work Plan to outline the proposed investigation approaches and techniques. The Work Plan was reviewed and accepted by NRS prior to the start of the work. The objectives of this initial work plan are noted in Section 1.0. Based on the preliminary results of the initial A-80 Investigation,



additional investigation activities were warranted to support the initial findings. The Supplemental A-80 Investigation was performed in accordance with the Supplemental Work Plan and the objectives of the supplemental field activities are noted in Section 1.0. As noted above, both work plans were provided to and agreed to by NRS and are provided in Appendix A.

3.0 FIELD INVESTIGATION

To accommodate the Town’s request, the A-80 field investigation was performed on the southwestern portion of the proposed CREC property, proximal to the area where the retention basin for the CREC facility is proposed to be located. The initial field investigation included the performance of the following activities.

Excavation and logging of five (5) shallow test pits, designated TP-1 through TP-5

o Included one additional test pit (TP-5) completed at the request of the Town

Drilling of two (2) soil borings, designated as BH-1 and BH-2

The supplemental A-80 field investigation included the performance of the following additional activities.

Excavation and logging of two (2) shallow test pits, designated as TP-6 and TP-7

Drilling of one (1) soil boring, designated as BH-3

Installation and development of one (1) monitoring well, within the completed BH-3 boring

Periodic monitoring of depth to water in the newly-installed monitoring well between October 26 and November 28, 2018

The locations of the completed test pits, borings and monitoring well are shown on Figure 2.

3.1 Field Methods

The following sections provide details on the field methodologies used for the completion of the shallow test pits, soil borings and well installation, as well as the monitoring of water levels in the BH-3 monitoring well. In addition to the activities described below, a reconnaissance of the southwestern area of the proposed CREC property was performed by an ESS geologist.

3.1.1 Test Pits

Shallow test pits were excavated to depths ranging from approximately three feet (TP-5) to eight feet (TP-3) below grade using a tire-mounted backhoe. Test pit excavations were observed in the field by an ESS geologist. Test pits TP-1 through TP-5 were completed on September 20, 2018. As noted previously, TP-5 was completed at the request of the Town. Test pits 6 and 7 were completed on October 24, 2018. Soils from the test pits were side-casted and then used to backfill the excavations. Depths to various soil layers and geologic deposits were measured in each test pit and recorded on test pit logs. Various other characteristics, such as approximate depth of groundwater seeping into test pits, apparent evidence of seasonally high groundwater, and difficulty of excavation, were also noted on the test pit logs where evidenced. Samples of the various soil types and subsurface materials were also collected for detailed logging and selective laboratory analysis (refer to Section 4.0).

Completed test pit logs are included in Appendix B.



3.1.2 Soil Borings

Soil borings were drilled using a track-mounted drilling rig. Soil borings BH-1 and BH-2 were drilled between September 10 and September 13, 2018. Soil boring BH-3 was drilled on October 26, 2018. Soil borings were observed in the field by an ESS geologist. Borings BH-1 and BH-2 were drilled using conventional drive and wash drilling techniques. Boring BH-3 was drilled using conventional hollow stem auger (HSA) drilling techniques. Boring BH-3 was drilled using HSA drilling techniques to eliminate the need to introduce water into the subsurface during drilling and allow for a more accurate evaluation of the degree of saturation of the subsurface materials at this location.

Split spoon samples were collected during the completion of all three borings to allow for detailed logging of the subsurface materials and collection of representative soil samples. Split spoon sampling was performed in accordance with Standard Penetration Test (SPT) techniques to also provide data on the in-situ density of the subsurface materials. Blow counts for each split spoon sample were recorded on field log sheets.

Completed boring logs are included in Appendix C. The split spoon sample intervals are noted on the boring logs.

3.1.3 Well Installation, Development and Monitoring

A shallow monitoring well was installed in the completed boring at location BH-3 (TP-2 location) to allow for the monitoring of groundwater levels at this location. Monitoring well construction was performed on October 26, 2018. The monitoring well was constructed using 2-inch inside diameter polyvinyl chloride (PVC) well materials (perforated screen and solid riser). The annular space surrounding the well materials was backfilled with clean silica sand. A 1.5-foot bentonite seal was also installed within the annular space above the top of the well screen. Details on the monitoring well construction are included on the BH-3 boring log in Appendix C.

Well Development

Well development was performed using a disposable PVC bailer on November 1, 2018. Approximately four (4) gallons of water was purged from the well during development. Well development was performed to remove fine-grained materials from the well that accumulated during well construction and to enhance the hydraulic connection between the well and the surrounding materials.

Water Level Monitoring

Depth to water measurements were performed using either a weighted plunker or an electronic water level meter relative to the top of the PVC well casing. Depth to water measurements were subsequently converted to depth below ground surface.

4.0 DATA ANALYSIS

Soil samples collected from soil borings and test pits were logged in the field or in the ESS Waltham office by an ESS geologist. Soil samples were logged using the USGS visual-manual classification scheme in accordance with the guide sheets included in Appendix D.

Physical parameters collected during the performance of soil borings and test pits (e.g., blow counts, total depth, etc.) and the results of the characterization of soil samples were documented on either soil boring



logs or test pit logs (Appendices B and C). The well construction details for the monitoring well installed at the BH-3 (TP-2) location are included on the BH-3 boring log.

Select soil samples were submitted to Alpha Analytical (Westborough, MA) for grain size and hydrometer testing. The objective of the grain size analysis was to determine the percentages of gravel, sands, silt and clay in each soil sample to assist in the classification of the soil samples. A summary of the results of the grain size analyses are presented on Table 4-1. A copy of the laboratory report is included in Appendix E.

The test pit and soil boring logs include a geologic interpretation regarding the nature of the subsurface materials encountered based on the field observations, classification of the subsurface materials, in-place density and general nature of the materials encountered at each location. The geologic interpretation also relied on the experience of the ESS geologist and review of various geologic and hydrogeologic reference materials.

Depth to water measurements collected in the BH-3 monitoring well were corrected to depth below ground surface and are summarized in Table 4-2 below. Converting the depth to water measurements to depth below groundwater surface allowed for an assessment of the degree of saturation of the interbedded sands identified at this location. Based on the measurements collected between October 26 and November 28, 2018, the depth to groundwater at this location ranged from 5.85 feet to 7.26 feet below ground surface (bgs).

5.0 FINDINGS AND CONCLUSIONS

The findings of the initial A-80 Zone field investigation and the supplemental A-80 Zone field investigation were used to evaluate whether stratified drift materials were present on the proposed CREC property.

The following findings were developed based on results of the field activities, characterization of soil samples, reconnaissance of the southwestern area of the CREC property and monitoring of groundwater levels in the BH-3 monitoring well.

Glacial till was encountered at all of the test pits and soil borings

o Glacial till was readily discernible from the interbedded sands observed at TP-2/BH-3

o Glacial till exhibited in place densities ranging from medium dense to very dense

o Glacial till is the parent material for all observed topsoil and subsoil, with the exception of the TP-2/BH-3 location



Interbedded sands, including some fine gravels, were only encountered at the TP-2/BH-3 location

o These interbedded sands exhibited in place densities classified as loose

o Glacial till was encountered beneath the interbedded sands

Soil samples collected during the performance of soil boring BH-3 suggest that there is a transitional zone (silty sands) between the interbedded sands and the underlying glacial till

o This transitional zone at BH-3 was estimated to occur between approximately 8.5 and 9.5 feet below ground surface (bgs)

o Underlying glacial till at BH-3, classified by soil texture and soil density, was estimated to be present below approximately 9.5 feet bgs

Depth to water measurements collected in the BH-3 monitoring well ranged from 5.85 to 7.26 feet bgs

o These measurements support that the lower approximately 2 to 3 feet of the interbedded sands are saturated at the BH-3 location.

These findings support the following conclusions regarding the presence of stratified drift materials on the CREC property.

The interbedded sands encountered at the TP-2/BH-3 location were the only subsurface materials identified that could meet the definition of stratified drift (refer to Section 2.0).

The interbedded sands are underlain by glacial till.

The findings of the initial and supplemental field investigations have clearly defined the extent of potential stratified drift deposits on the Property.

o The area of higher topographic elevation (delineated by the dashed line on the snapshot below from the current CREC site plan) is generally consistent with the delineation of the potential stratified drift materials based on the findings of the subsurface activities and field reconnaissance of the A-80 investigation area and immediately surrounding areas.



It is estimated that stratified drift materials may underlie approximately 6,135 ft2 (approximately 0.14 acres) of the proposed CREC property. This represents approximately 0.2% of the overall 67-acre Property.

The results of the water level monitoring support that the lower portion of the interbedded sands are saturated at the BH-3 location, at least under the rainfall and groundwater recharge conditions existing at the time measurements were collected.

The following graphic summarizes the stratigraphy and depth to water information obtained for the TP-2/BH-3 location.



NOTES: represents approximate average depth of water table during October/November 2018

No additional field activities are warranted to further define the area of potential stratified drift on the Property. Invenergy will review the findings of this investigation with the Town and determine if any modifications to the proposed facility design are warranted to not encumber the A-80 overlay district.

A-80 Investigation Work Plans

Focused Work Plan – A-80 Investigation Proposed CREC Property Burrillville, Rhode Island

This focused work plan provides details on the scope of the proposed subsurface investigation on the proposed CREC Property in the Town of Burrillville (the Property). The investigation is being completed on behalf of Invenergy Thermal Development LLC (the Client) in support of their EFSB application.

BACKGROUND The Town of Burrillville has established aquifer protection zoning (Section 30-202. – Aquifer Zoning, Burrillville, RI Code of Ordinances) based on historic geologic mapping completed by the USGS (USGS, 1974) in order to protect these resources. The USGS mapped the extent of stratified drift within the Branch River Basin, which includes the Town of Burrillville. The Town of Burrillville aquifer protection zoning is based on this extent of stratified drift as mapped by the USGS. The aquifer protection zoning also reportedly takes into consideration public water supply Wellhead Protection Areas mapped by the RIDEM.

OBJECTIVES The objectives of the investigation are as follows.

• To demonstrate whether the subsurface conditions (i.e., presence/absence of “meaningful” stratified drift) along the southwestern boundary of the Property support inclusion of this area within the A-80 Overlay District.

• To demonstrate, in conjunction with the findings of the 2015 Geotechnical Investigation performed by GZA GeoEnvironmental, Inc. (GZA, 2015), whether the subsurface conditions are consistent with the subsurface conditions within the remainder of the proposed area of development.

FIELD METHODS Field Preparation

Field preparation activities will need to be completed prior to the initiation of the borings or test pits to ensure that these activities are completed within the Property, proximal to the A-80 Overlay District boundary and outside of the delineated wetland resource areas and their associated buffer zones. These activities will include the following:

• Flagging (or similar) identification of the proposed CREC Property boundary, wetland buffer zone boundary, and A-80 Overlay District boundary by the Project surveyor

• Staking of the proposed boring and test pit locations by the Project surveyor

• DIGSAFE clearance of the proposed borings and test pits (after locations are staked by surveyor)

o Requires 72-hours to obtain clearance

• Determination of access to the proposed locations for the drill rig and backhoe

Borings and test pits will be performed along the southwestern boundary of the proposed CREC Property, outside of the delineated wetland resource areas and their associated buffer zones and within the proposed CREC Property. Refer to Figure A for the approximate location of the borings and test pits. Actual locations for the borings and test pits will be made at the time these activities are undertaken based on field conditions and access.

Soil samples will be collected and logged in the field to evaluate the subsurface conditions in the area of the proposed CREC Property nearest to the designated A-80 Overlay District boundary. Additional details on the proposed approach for the borings and test pits is provided below.

Borings

Soil borings will be completed using standard drive and wash drilling techniques, similar to the technique used for the geotechnical borings on the Property (GZA, 2015). Soil samples will be collected at five-foot intervals to allow for observation and characterization of the subsurface materials. Soil samples may also be collected for grain size analysis (sieve and hydrometer), if warranted. Soil samples will be collected using a 2-inch diameter split spoon sampler in accordance with the requirements of the Standard Penetration Test (SPT) procedure to allow for characterization of the soil density. Borings will be completed to the bedrock surface or to an adequate depth as determined by the field scientist. Based on the findings of the borings completed by GZA, it is estimated that boring depths will range from 40 to 55 feet below ground surface (bgs).

Test Pits

Test pits will be completed to provide additional subsurface information along the proposed property boundary between the borings as identified in Figure A. Test pits will be completed using a backhoe or excavator. Based on the results of the GZA geotechnical evaluation, combined topsoil and subsoil depths ranged from approximately 2 to 3 feet bgs. Test pits will be completed to 6 to 8 feet bgs to allow for characterization of the subsurface materials underlying the soil horizon. Representative soil samples will be collected in gallon-size plastic bags for grain size analysis (sieve and hydrometer). Test pits will be backfilled with the excavated materials upon completion.

REPORTING The findings of the proposed subsurface investigation will be summarized in a letter report. The report will include the following, at a minimum.

• boring logs and test pit logs

• laboratory analytical report(s) (grain size analysis)

• figure showing the locations of the completed borings and test pits

• text describing the following:

o field preparation activities

o methods used for completion of the borings and test pits

Focused Work Plan – Supplemental A-80 Investigation Proposed CREC Property Burrillville, Rhode Island

This supplemental work plan provides details on the scope of the additional subsurface investigations proposed on the CREC Property in the Town of Burrillville (the Property). The investigation is being completed on behalf of Invenergy Thermal Development LLC (the Client) in support of their EFSB application.

BACKGROUND

The Town of Burrillville has established aquifer protection zoning (Section 30-202. – Aquifer Zoning, Burrillville, RI Code of Ordinances) based on historic geologic mapping completed by the USGS (USGS, 1974) in order to protect these resources. The USGS mapped the extent of stratified drift within the Branch River Basin, which includes the Town of Burrillville. The Town of Burrillville aquifer protection zoning is based on this extent of stratified drift as mapped by the USGS. The aquifer protection zoning also reportedly takes into consideration public water supply Wellhead Protection Areas mapped by the RIDEM.

Based on the preliminary results of the initial A-80 Investigation, additional investigation activities are warranted to support the initial findings.

OBJECTIVES

The objectives of the supplemental investigation are as follows.

To assess the northern extent of subsurface materials at the Test Pit-2 location.

To evaluate the depth to the water table at the Test Pit-2 location.

FIELD METHODS

Field Preparation

Field preparation activities will need to be completed prior to the initiation of the borings or test pits. These activities will include the following:

Staking of the proposed test pit locations by the Project surveyor

DIGSAFE clearance of the proposed boring and test pits (after locations are staked by surveyor)

o May be able to perform work under or extend the previous clearances for the completed borings and test pits

Determination of access to the proposed boring location for the drill rig and test pit locations for backhoe

o Limited clearing may be necessary to access investigation locations

Coordination with subcontractors

The additional boring and test pits will be performed proximal to the southwestern boundary of the proposed CREC Property, outside of the delineated wetland resource areas and their associated buffer zones and within the proposed CREC Property. Refer to Figure A for the approximate location of the additional boring

and test pits. Actual locations for the boring and test pits will be determined at the time these activities are undertaken based on field conditions and access.

Soil samples will be collected and logged in the field to evaluate the subsurface conditions encountered at each location. Additional details on the proposed approach for the borings and test pits is provided below.

Boring

One additional soil boring will be completed at the Test Pit-2 location using standard hollow stem auger (HSA) drilling techniques. HSA drilling technique is proposed to avoid introducing water into the formation during the drilling process.

Soil samples will be collected at five-foot intervals to allow for observation and characterization of the subsurface materials. Soil samples may also be collected for grain size analysis (sieve and hydrometer), if warranted. Soil samples will be collected using a 2-inch diameter split spoon sampler in accordance with the requirements of the Standard Penetration Test (SPT) procedure to allow for characterization of the soil density. The boring will be advanced into the glacial till suspected to underlie the sandy materials identified in Test Pit-2.

Upon completion of the boring, a 2-inch diameter PVC monitoring well will be constructed. The well will be constructed with five or ten feet of well screen located at the top of the till materials. Upon completion of the well construction, an electronic water level meter will be used to determine if groundwater is present in the well. If groundwater is present, limited well development may be performed to remove any fines from the well and enhance the hydraulic connection with the surrounding materials.

Additional water level measurements will be performed approximately one week and two weeks after well construction.

Test Pits

Additional test pits will be completed at approximately 25 to 50-foot spacings, as needed, to further characterize the subsurface materials on the southwestern portion of the Property. The two supplemental test pit locations shown on Figure A show the general direction the test pits will be performed relative to the Test Pit-2 location. Additional test pits, in addition to those shown on the attached plan, may be performed to refine the assessment. Test pits will be completed using a backhoe or excavator. Test pits will be completed to approximately 6 to 8 feet bgs to allow for characterization of the subsurface materials underlying the soil horizon. Representative soil samples may be collected in gallon-size plastic bags for grain size analysis (sieve and hydrometer). Test pits will be backfilled with the excavated materials upon completion.

REPORTING

The findings of the proposed supplemental subsurface investigation will be summarized in the letter report proposed in the initial A-80 Investigation Work Plan.

GENERAL NOTES:

1. Logs of subsurface explorations depict subsurface soil, rock, and water conditions only at the specific locations and on the dates indicated. Soil and rock conditions and water levels at other locations may differ from conditions and levels occurring at the subsurface exploration locations. Also, the passage of time may result in a change in the conditions and water levels at the subsurface exploration locations.

2. Water levels noted on the logs were monitored at the times and under the conditions indicated. In test borings, these water levels could have been affected by the introduction of water into the boring during drilling, extraction of tools, or other procedures and thus may not reflect the actual groundwater level at the test boring location. Fluctuations in groundwater levels can occur due to variations in precipitation, season, tidal fluctuation, adjacent construction activity and other factors.

Case Narrative

The samples were received in accordance with the Chain of Custody and no significant deviations were encountered during the preparation

or analysis unless otherwise noted. Sample Receipt, Container Information, and the Chain of Custody are located at the back of the report.

Results contained within this report relate only to the samples submitted under this Alpha Lab Number and meet NELAP requirements for all

NELAP accredited parameters unless otherwise noted in the following narrative. The data presented in this report is organized by parameter

(i.e. VOC, SVOC, etc.). Sample specific Quality Control data (i.e. Surrogate Spike Recovery) is reported at the end of the target analyte list

for each individual sample, followed by the Laboratory Batch Quality Control at the end of each parameter. Tentatively Identified Compounds

(TICs), if requested, are reported for compounds identified to be present and are not part of the method/program Target Compound List,

even if only a subset of the TCL are being reported. If a sample was re-analyzed or re-extracted due to a required quality control corrective

action and if both sets of data are reported, the Laboratory ID of the re-analysis or re-extraction is designated with an "R" or "RE",

respectively. When multiple Batch Quality Control elements are reported (e.g. more than one LCS), the associated samples for each element

are noted in the grey shaded header line of each data table. Any Laboratory Batch, Sample Specific % recovery or RPD value that is outside

the listed Acceptance Criteria is bolded in the report. All specific QC information is also incorporated in the Data Usability format of our Data

Merger tool where it can be reviewed along with any associated usability implications. Soil/sediments, solids and tissues are reported on a

dry weight basis unless otherwise noted. Definitions of all data qualifiers and acronyms used in this report are provided in the Glossary

located at the back of the report.

In reference to questions H (CAM) or 4 (RCP) when "NO" is checked, the performance criteria for CAM and RCP methods allow for some

quality control failures to occur and still be within method compliance. In these instances the specific failure is not narrated but noted in the

associated QC table. The information is also incorporated in the Data Usability format of our Data Merger tool where it can be reviewed

along with any associated usability implications.

Please see the associated ADEx data file for a comparison of laboratory reporting limits that were achieved with the regulatory Numerical

Standards requested on the Chain of Custody.

HOLD POLICY

For samples submitted on hold, Alpha's policy is to hold samples (with the exception of Air canisters) free of charge for 21 calendar days

from the date the project is completed. After 21 calendar days, we will dispose of all samples submitted including those put on hold unless

you have contacted your Client Service Representative and made arrangements for Alpha to continue to hold the samples. Air canisters will

be disposed after 3 business days from the date the project is completed.

Please contact Client Services at 800-624-9220 with any questions.

Grain Size Analysis

The WG1161946-1 Laboratory Duplicate RPDs for % fine gravel (34%), % total gravel (34%) and % clay fine

(37%), performed on L1838538-01, are outside the acceptance criteria. The elevated RPDs have been

attributed to the non-homogeneous nature of the native sample.

I, the undersigned, attest under the pains and penalties of perjury that, to the best of my knowledge and belief and based upon my personal inquiry of those responsible for providing the information contained in this analytical report, such information is accurate and complete. This certificate of analysis is not complete unless this page accompanies any and all pages of this report.

Estimated Detection Limit: This value represents the level to which target analyte concentrations are reported as estimated values, when those target analyte concentrations are quantified below the reporting limit (RL). The EDL includes any adjustments from dilutions, concentrations or moisture content, where applicable. The use of EDLs is specific to the analysis of PAHs using Solid-Phase Microextraction (SPME).Estimated Maximum Possible Concentration: The concentration that results from the signal present at the retention time of an analyte when the ions meet all of the identification criteria except the ion abundance ratio criteria. An EMPC is a worst-case estimate of the concentration.Environmental Protection Agency.

Laboratory Control Sample: A sample matrix, free from the analytes of interest, spiked with verified known amounts of analytes or a material containing known and verified amounts of analytes.Laboratory Control Sample Duplicate: Refer to LCS.

Laboratory Fortified Blank: A sample matrix, free from the analytes of interest, spiked with verified known amounts of analytes or a material containing known and verified amounts of analytes.Method Detection Limit: This value represents the level to which target analyte concentrations are reported as estimated values, when those target analyte concentrations are quantified below the reporting limit (RL). The MDL includes any adjustments from dilutions, concentrations or moisture content, where applicable.Matrix Spike Sample: A sample prepared by adding a known mass of target analyte to a specified amount of matrix sample forwhich an independent estimate of target analyte concentration is available. Matrix Spike Sample Duplicate: Refer to MS.

Not Applicable.

Not Calculated: Term is utilized when one or more of the results utilized in the calculation are non-detect at the parameter's reporting unit.N-Nitrosodiphenylamine/Diphenylamine.

Not Ignitable.

Non-Plastic: Term is utilized for the analysis of Atterberg Limits in soil.

Reporting Limit: The value at which an instrument can accurately measure an analyte at a specific concentration. The RL includes any adjustments from dilutions, concentrations or moisture content, where applicable.Relative Percent Difference: The results from matrix and/or matrix spike duplicates are primarily designed to assess the precision of analytical results in a given matrix and are expressed as relative percent difference (RPD). Values which are less than five times the reporting limit for any individual parameter are evaluated by utilizing the absolute difference between the values; although the RPD value will be provided in the report.Standard Reference Material: A reference sample of a known or certified value that is of the same or similar matrix as the associated field samples.Semi-dynamic Tank Leaching Procedure per EPA Method 1315.

Toxic Equivalency Factors: The values assigned to each dioxin and furan to evaluate their toxicity relative to 2,3,7,8-TCDD.

Toxic Equivalent: The measure of a sample¿s toxicity derived by multiplying each dioxin and furan by its corresponding TEF and then summing the resulting values.Tentatively Identified Compound: A compound that has been identified to be present and is not part of the target compound list (TCL) for the method and/or program. All TICs are qualitatively identified and reported as estimated concentrations.

Analytical Method: Both the document from which the method originates and the analytical reference method. (Example: EPA 8260B is shown as 1,8260B.) The codes for the reference method documents are provided in the References section of the Addendum.Final pH: As it pertains to Sample Receipt & Container Information section of the report, Final pH reflects pH of container determined after adjustment at the laboratory, if applicable. If no adjustment required, value reflects Initial pH.Frozen Date/Time: With respect to Volatile Organics in soil, Frozen Date/Time reflects the date/time at which associated Reagent Water-preserved vials were initially frozen. Note: If frozen date/time is beyond 48 hours from sample collection, value will be reflected in 'bold'.Initial pH: As it pertains to Sample Receipt & Container Information section of the report, Initial pH reflects pH of container determined uponreceipt, if applicable.Total: With respect to Organic analyses, a 'Total' result is defined as the summation of results for individual isomers or Aroclors. If a 'Total' result is requested, the results of its individual components will also be reported. This is applicable to 'Total' results for methods 8260, 8081 and 8082.

1 The reference for this analyte should be considered modified since this analyte is absent from the target analyte list of the original method.

Spectra identified as "Aldol Condensation Product".

The analyte was detected above the reporting limit in the associated method blank. Flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times (10x) the concentration found in the blank. For MCP-related projects, flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times (10x) the concentration found in the blank. For DOD-related projects, flag only applies to associated field samples that have detectable concentrations of the analyte at less than ten times (10x) the concentration found in the blank AND the analyte was detected above one-half the reporting limit (or above the reporting limit for common lab contaminants) in the associated method blank. For NJ-Air-related projects, flag only applies to associated field samples that have detectable concentrations of the analyte above the reporting limit. For NJ-related projects (excluding Air), flag only applies to associated field samples that have detectable concentrations of the analyte, which was detected above the reporting limit in the associated method blank or above five times the reporting limit for common lab contaminants (Phthalates, Acetone, Methylene Chloride, 2-Butanone). Co-elution: The target analyte co-elutes with a known lab standard (i.e. surrogate, internal standards, etc.) for co-extracted analyses.Concentration of analyte was quantified from diluted analysis. Flag only applies to field samples that have detectable concentrations of the analyte.Concentration of analyte exceeds the range of the calibration curve and/or linear range of the instrument.

The concentration may be biased high due to matrix interferences (i.e, co-elution) with non-target compound(s). The result should be considered estimated.The analysis of pH was performed beyond the regulatory-required holding time of 15 minutes from the time of sample collection.
