Receipt
The samples were received on 4/16/2020 2:38 PM; the samples arrived in good condition, properly preserved and, where required, on ice.

The temperature of the cooler at receipt was 2.7º C.

GC Semi VOA
Method 8081A: The RPD of the laboratory control sample (LCS) and laboratory control sample duplicate (LCSD) for preparation batch 570-63501 and analytical batch 570-63508 recovered outside control limits for the following analytes: alpha-BHC, Aldrin, beta-BHC, Dieldrin, Endosulfan I, Endosulfan II, Endosulfan sulfate, Endrin aldehyde, Endrin ketone, gamma-BHC, Heptachlor and Heptachlor epoxide. The associated MS/MSD precision was within acceptance limits.therefore data has been reported and qualified.

Method 8081A: Due to the additional level of 4,4'-DDE and 4,4'-DDT present in the spiked samples, the concentration of 4,4'-DDE and 4,4'-DDT in the MS/MSD was above the instrument calibration range. The data have been reported and qualified.

Method 8081A: The continuing calibration verification (CCV) associated with batch 570-63736 recovered above the upper control limit for <Hexachlorobenzene>. The samples associated with this CCV were non-detects for the affected analytes; therefore, the data have been reported.

Method 8081A: The continuing calibration verification (CCV) associated with <Analytical Batch> recovered high and outside the control limits for < Endosulfan sulfate> on one column. Results are confirmed on both columns and reported from the passing column.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Receipt
The samples were received on 4/13/2020 2:07 PM; the samples arrived in good condition, properly preserved and, where required, on ice.

The temperature of the cooler at receipt was 2.1º C.

HPLC/IC
Sample B7-0.5 could not be completed for EPA 7199 due to lack of sample volume.

No additional analytical or quality issues were noted, other than those described in the Definitions/Glossary page.

GC Semi VOA
Method 8151A: The matrix spike / matrix spike duplicate (MS/MSD) recoveries and precision for preparation batch 570-65548 and 570-65548 and analytical batch 570-66030 were outside control limits. Sample matrix interference and/or non-homogeneity are suspected because the associated laboratory control sample / laboratory sample control duplicate (LCS/LCSD) precision was within acceptance limits.

Method 8151A: The continuing calibration verification (CCV) associated with 570-66030 recovered high and outside the control limits for Dalapon on one column. Results are confirmed on both columns and reported from the passing column.

Method 8151A: The laboratory control sample and/or the laboratory control sample duplicate (LCS/LCSD) for preparation batch 570-65548 and analytical batch 570-66030 recovered outside control limits for the following analyte(s): Dinoseb. Dinoseb has been identified as a poor performing analyte when analyzed using this method; therefore, re-extraction/re-analysis was not performed. Batch precision also exceeded control limits for these analyte(s). These results have been reported and qualified.

Method 8151A: The matrix spike/matrix spike duplicate (MS/MSD) for preparation batch 570-65548 and 570-65548 and analytical batch 570-66030 exceeded control limits for the following analyte(s): Dinoseb, Note that this analyte is a known poor performer when analyzed using this method.

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Metals
Method 7471A: The matrix spike / matrix spike duplicate (MS/MSD) recoveries for preparation batch 570-65833 and analytical batch 570-66013 were outside control limits. Sample matrix interference and/or non-homogeneity are suspected because the associated laboratory control sample (LCS) recovery was within acceptance limits.

Method 7471A: Elevated reporting limits are provided for the following sample due to insufficient sample provided for preparation:B7-0.5 (570-25647-1).

No additional analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

Organic Prep
Method 8151A: The following sample was unable to be prepared and/or analyzed due to broken glassware : (570-25647-A-1 MS).

Method 8151A: The following sample was re-prepared outside of preparation holding time due to broken glassware: (570-25647-A-1 MS).

Hi Steve,

We would like to perform the following additional analysis on samples that you have from job number J25057‐1 and J25647‐1:

B4‐0.5, B4‐3.0, B6‐0.5, B6‐3.0, B7‐0.5, B7‐3.0, B8‐0.5, B8‐3.0, B9‐0.5, B9‐3.0, B10‐0.5, and B10‐3.0 for Title 22 Metals EPA 6010B/7471A and Hex Chrome EPA 3060A/7199.

Please let me know if you have any qu
estions.

Thanks!!

Subject: RE: Huntington Beach 17631 Cameron Lane analysis questions

Laura-

1. Would it be possible to have all 50 samples re‐run for herbicides and Title 22 Metals? EPA 8151 for herbicides and EPA 6010B/7471A for Title 22 metals‐ yes. Holding time for EPA 8151 is 14 days. Sample collected prior to or on 04/08/20 are already past holding time.

2. Would it be possible to re‐run some of the samples for hex chrom e?
Yes – EPA 3060A/7196A or EPA 3060A/7199?

3. What would be the cost for these analyses on a 5‐day TAT and a 48‐hour TAT? EPA 8151 ‐ $200 on 10 day TAT.

EPA 6010B/7471A for Title 22 me tals ‐ $80
EPA 3060A/7196A‐ $60
EPA 3060A/7199 ‐ $80

We can’t rush any of this at this time- these methods (8151 and Hex Cr) take additional time in preparation. Quickest TAT is 10 working days.

Hi Steve,

Yes, please change them – that will be awesome. It would be for both of the attached requests I made to you yesterday (though I’m sure you already know this).

Can you also please change the TAT for the samples we just collected today (job 570‐26822‐ attached) to 72‐hr TAT?

Thanks so mu
ch!!

Site Assessment Report June 25, 2020

S3506.02T, Huntington Beach, CA 1 EEC

1.0 INTRODUCTION

On behalf of the City of Huntington Beach, EEC Environmental (EEC) has prepared this Site Assessment Report for the property located at 17642 Beach Boulevard, Huntington Beach, California (subject property; Figure 1, Site Location Map). The purpose of the site assessment was to address findings of EEC’s Phase I Environmental Site Assessment (ESA) dat ed March 18, 2020. The Phase I ESA identified the following environmental concerns: potential use of pesticides/herbicides and lead‐based paint in connection with former agricultural and residential use of the subject property, and the lack of specific information related to the former use of the east half of the subject property as a storage lot in the 1960s. The Phase I ESA recommended soil sampling and a geophysical survey. The Phase I ESA and the site assessment were completed in connection with a proposed real estate transaction.

This report documents the methods, procedures, and results of the site assessment activities at the subject prop
erty. All work was completed in general accordance with EEC’s April 2, 2020 proposal to the City of Huntington Beach (EEC, 2020) and subsequent correspondence between the City of Huntington Beach and EEC. All work was performed under the supervision of a California licensed Professional Ge
ologist (PG).

1.1 Scope of Work

The completed site assessment activities included the following tasks:

 Preparing a site‐specific health and safety plan (HASP) appropriate for the scope of work.  Contacting Underground Service Alert (USA) a minimum of 72 hours prior to initiation of fieldwork.
 Conducting a geophysical survey.
 Advancing 9 soil borings to total dept hs ranging between 3 feet and 8 feet below ground surface (bgs) and collecting soil samples.
 Analyzing soil samples.

2.0 BACKGROUND

2.1 Site Description

The approximately 0.79‐acre subject property consists of an undeveloped lot identified as Assessor Parcel Number (APN) 167‐042‐09, located at 17642 Beach Boulevard in Huntington Beach, Orange County, California. A Phase I ESA was completed for the subject property on March 18, 2020 (EEC, 2020).

The Phase I ESA indicated th at based on a review of historical aerial photographs, the subject property appeared to be used for agricultural purposes (row crops) from the 1930s to the 1950s and given this usage, it is possible that pesticides and/or herbicides were once used onsite. Additionally, due to the date of construction of the former onsite residences (1930s), lead‐based paint may have been use d onsite. Further, during the 1960s, the east half of the subject property appeared to be used as a storage lot, but information was not obtained related to the specific use. During site reconnaissance for the Phase I ESA, uneven topography was ob served on this portion of the subject property.

Based on this information, the Phase I ESA recommended soil sampling to assess for potential residual pesticides and herbicides from former agricultural use; to assess for potential lead in the locations of the Site Assessment Report June 25, 2020

S3506.02T, Huntington Beach, CA 2 EEC
former residences; and to assess for potential contamination (such as petroleum hydrocarbons, metals, and solvents) from the use of the east half of the property as a storage lot. The Phase I ESA also recommended a geophysical survey to determine if any buried items are present due to the former use as a storage lot.

2.2 Physiography

The most recent topographic map coverage of the subject property is provided by the U.S. Geological Survey (USGS) 7.5‐minute, Newport Beach, California quadrangle map, dated 2012 (Figure 1). According to the USGS topographic map, the subject property is located at an elevation of approximately 25 to 30 feet above mean sea level (msl). The to pography in the general subject property area slopes gently to the north‐northeast.

2.3 Geology and Hydrogeology

Onsite activities described in this report indicated that soil at the subject property consists primarily of silt and silty sand from 1 to 5 feet bgs. At 5 feet bgs, soil consists primarily of clayey sand and sandy clay.

At 8 feet bgs soil consists of sand and clayey sand with gravel.

According
to a Quarterly Status Report, Second Quarter 2019 for a site located approximately 500 feet northwest of the subject property, the groundwater flow direction is southwest (Atlas Environmental Engineering, Inc., 2019). During site assessment activities performed by EEC on the north adjoining parcel (17631 Cameron Lane) in May 2020, groundwater was encountered at 23 and 24 feet bgs.

3.0 SITE INVESTIGATION ACTIVITIES

Between April 13 and May 11, 2020, a total of 9 soil borings were advanced to depths ranging from approximately 3 to 8 feet bgs for the collection of soil samples at the subject property. Additionally, on April 13, 2020, a geophysical survey was completed at the subject property.

3.1 Pre‐Field Activities

Prior to beginning soil sampling activities, EEC completed the following tasks necessary to initiate field activity.

3.1.1 Health and Safety Plan

To protect workers, EEC prepared a site‐specific HASP as appropriate for the scope of work. The HASP informed all site workers of potential risks during field sampling activities and provided engineering controls to avoid physical and chemical hazards. The HASP addressed potential physical and chemical hazards associated with field operations. The HASP outlined the steps to prevent ex posures from all site activities. The HASP also described the safe use of equipment, evaluation of hazards, safe investigation procedures, personal protective equipment, emergency procedures and training required to conduct the site assessment under typical Hazardous Waste Operations and Emergency Response protocol.

S3506.02T, Huntington Beach, CA 3 EEC

3.1.2 Utility Clearance

EEC contacted USA and provided the specific property boundaries so that the proposed work area was provided to utility owners responding to the USA ticket. USA is a regional notification center that notifies owners and operators of subsurface utilities (water, gas, electric, sewer, oil lines, etc.) and informs them of a contractor’s intent to perform subsurface work. EEC notified USA of the intent to perform subsurface work a minimum of 72 hours prior to the beginning of the on‐site activities.

3.1.3 Geophysical Survey

On April 13, 2020, EEC oversaw SubSurface Surveys complete a geophysical survey at the subject property. The geophysical survey was performed to determine if any buried items were present related to the former use as a storage lot. Specifically, the geophysical survey was performed to locate and identify any underground storage tanks (USTs ), backfilled excavations, piping, conduit, or other buried features. The geophysical survey also determined that the boring locations were clear of any piping, conduit, or other buried utilities. The geophysical survey was performed using a combination of electromagnetic induction (EM), magnetometry, and ground penetrating radar (GPR).

Piping and utilities that were found were marked with paint or flags. Numero us metal anomalies were found beneath the ground surface at the subject property. After further investigation with geophysical instrumentation, the anomalies were found to be former or active utility lines and buried metal junk debris. All buried objects were documented on Figure 3 included with th e Geophysical Survey report (Appendix A, Geophysical Survey Report). The Geophysical Survey did not identify any USTs or backfilled areas.

3.2 Hand‐Auger Soil Boring Advancement and Soil Sampling

Between April 13 and May 11, 2020 EEC advanced a total of 7 hand‐auger soil borings at the subject property (B19 through B25; Figure 2, Boring Location Map) to a depth of 3 feet bgs. Once each sampling depth was reached, the hand auger was removed from the borehole and an undisturbed soil sample was collected using a slide hammer sampler including a stainless steel sampling sleeve. Following sample retrieval, both ends of the sleeve were covered with a Teflon sheet and sealed with a plastic end cap.

Soil samples were then labeled with an identification number, sealed in a plastic bag, and placed into a chilled cooler.

An unused portion
of soil from each sampling interval was used for field screening using a photoionization detector (PID) for evaluation of organic vapor content and for logging lithology. Field screening was conducted by placing a portion of the unpreserved soil in a sealable plastic bag for approximately 10
minutes. The organic vapor concentration in the headspace of the plastic bag was then measured using a PID. Soil descriptions and PID measurements were recorded and documented on field notes. All field activities were performed under the direct oversight of a PG.

All soil samples were collected and transferred under proper chain‐of‐custody protocols to Eurofins Calscience (Calscience) of Garden Grove, a California state‐certified laboratory. Selected soil samples were analyzed for organochlorine pesticides (OCPs) by United States Environmental Protection Agency (US
EPA) Method 8081A, lead by USEPA Method 6010B, California Title 22 metals by USEPA Method 6010B, mercury by USEPA Method 7471A, hexavalent chromium by USEPA Method 7199, volatile organic compounds (VOCs) by USEPA Method 8260B, and total petroleum hydrocarbons carbon chain Site Assessment Report June 25, 2020

S3506.02T, Huntington Beach, CA 4 EEC
(TPH‐cc) by USEPA Method 8015B. The specific soil sampling method for each sample location is provided in Table 3‐1, Soil Sampling Matrix, on Page 5 of this report.

3.3 Geoprobe Drilling and Soil Sampling

Results of the hand auger soil sampling identified elevated concentrations of hexavalent chromium and lead in B19 and B22, respectively. In order to better understand the vertical and lateral distribution of hexavalent chromium and lead at the subject property, EEC oversaw Strongarm Environmental Field Services, Inc. (Strongarm) drill 2 Geoprobe borings at the subjec t property for the collection of soil samples on May 11, 2020. The borings were placed adjacent to previous boring locations where elevated concentrations of hexavalent chromium and lead were found; therefore, they were given similar nomenclature (B19‐A and B22‐A; Figure 2).

The borings were advanced using Geoprobe direct‐push drilling technology and hand‐ auger equipment to a total depth of eight feet bgs. Direct‐push drilling rigs are hydraulically powered soil probing machines that use both static force and percussion to drive steel boring rods into the subsurface. Before the initiation of drilling, Strongarm cleared the upper 5 feet of the borehole with a hand auger to verify the absence of underground utilities or other shallow obstructions.

A soil sample was collected from 4 feet bgs from each boring using the hand auger. The hand auger was removed from the borehole and an undisturbed soil sample was collected usi ng a slide hammer sampler including a stainless steel sampling sleeve. Following sample retrieval, both ends of the sleeve were covered with a Teflon sheet and sealed with a plastic end cap.

During direct‐push drilling, continuous soil samples were collected using 5‐foot long acetate sleeves. The direct‐push rig hydraulica lly drove the sampling sleeve the entire 5‐foot interval. Following sample retrieval the portion of the sleeve chosen for samples (i.e., 5 feet bgs, 6 feet bgs, 7 feet bgs, and 8 feet bgs) was cut and the ends of each sample were covered with Teflon sheets and sealed with plastic end caps. Soil samples were then labele
d with an identification number, sealed in a plastic bag, and placed into a chilled cooler.

An unused portion of soil from each sampling interval was used for field screening using a PID for evaluation of organic vapor content and for logging lithology. Field screening was conducted by placing a portion of the unpreserved soil in
a sealable plastic bag for approximately 10 minutes. The organic vapor concentration in the headspace of the plastic bag was then measured using a PID. Soil descriptions and PID measurements were recorded and documented on field notes. All field activities were performed under the direct oversight of a California PG.

The collected soil samples were transferred under proper chain‐of‐custody protocols to Calscience. All soil samples collected from B19‐A were analyzed for hexavalent chromium by USEPA Method 7199 and the soil sample collected from 4 feet bgs from B‐ 22A was analyzed for hexavalent chromium by USEPA Method 7199 and lead by USEPA Method 6010B.

4.0 SAMPLING RESULTS

4.1 Soil

A total of 20 soil samples were collected and analyzed for California Title 22 metals, hexavalent chromium, lead, mercury, OCPs, TPH‐cc, and VOCs and between April 13 and May 11, 2020 (Table 3‐1).

The soil laboratory results are summarized below and in Table 1, Summary of Soil Analytical Results – Metals
and Table 2, Summary of Soil Analytical Results – Pesticides, TPH, and VOCs. Estimated values (J) detected below the reporting limit and above the laboratory method detection limit are included in the summary. Analytical results were compared to the USEPA Regional Screening Levels (RSLs) for residential soil and DTSC Screening Lev els (SLs) for residential soil. If both RSLs and SLs were available for a particular analyte, then the more stringent value was used. Laboratory analytical results, chain‐of‐ custody documentation, and quality control data are provided in Appendix B, Laboratory Analytical Reports, Chain‐of‐Custody Record, and QA/QC Data.

4.1.1 Metals

 With the exception of lead and hexavalent chromium, metals detected in soil samples were at concentrations below their respective USEPA RSLs, DTSC SLs, or established background levels.

 Lead was detected at 91.3 milligrams per kilogram (mg/kg) in B22‐3.0, exceeding the USEPA RSL of 82 mg/kg and DTSC SL of 80 mg/kg. In the four foot sample collected from B22‐A, immediately adjacent to B22, lead was detected at 3.24 mg/kg, below both the USEPA RSL and DTSC SL. The four foot sample results indicated that lead at this location has been defined vertically.

 Hexavalent chromium was detected at 310 micrograms per kilogram (µg/kg) in B19‐3.0, which exceeded the USEPA RSL and DTSC SL of 300 µg/kg. In soil samples collected from B19‐A, Site Assessment Report June 25, 2020

S3506.02T, Huntington Beach, CA 6 EEC
immediately adjacent to B19, hexavalent chromium was detected at 350 µg/kg at 4 feet bgs and at 310 µg/kg at 5 feet bgs. At 6 feet bgs, hexavalent chromium was not detected above 400 µg/kg, which was the lowest method detection limit the laboratory could achieve due to the high mineral content of the sample. Therefore, it was not determined if the hexavalent chromium concentration in the 6‐foot sample from B19‐A exceeded the USEPA RSL and DTSC SL.

Samples collected from 7 and 8 feet bgs in B19‐A were not detected above the method detection limit of 200 µg/kg, resulting in vertical delineation at this location.

4.1.2 Pesticides, TPH, and VOCs

 Several organochlorine pesticides were detected in shallow soil, including 4,4’‐ Dichlorodiphenyldichloroethylene (4‐4’‐DDE), 4‐4’ Dichlorodiphenyltrichloroethane (4,4’‐DDT), and toxaphene. All concentrations were below the USEPA RSLs and DTSC SLs for residential soil.

 TPH‐cc was detected in low concentrations in shallow soil. No USEPA RSLs or DTSC SLs are established for TPH; however, these concentrations are not viewed as a risk driver for the subject property.

 VOCs were not detected above laboratory reporting limits in any of the soil samples that were analyzed.

4.2 Investigation Derived Waste and Excavated Soil

Soil cuttings and decontamination water generated during this assessment work were stored onsite in ten United States Department of Transportation (DOT) approved 55‐gallon drums. The drums were labeled documenting the accumulation start date, description of contents, and applicable contact information. Wastes will be profiled, manifested, and disposed of within 90 days of gen eration. If available at the time of report preparation, the manifest(s) signed by the disposal facility will be included in the final report.

5.0 CONCLUSIONS AND RECOMMENDATIONS

This site assessment was performed to address the findings of the Phase I ESA report. Based on the results of the site assessment, soil with elevated concentrations of hexavalent chromium was found in B19 and B19‐A at depths between approximately 3 and 6 feet bgs and soil with elevated concentrations of lead was found in B22 at a depth of 3 feet bgs. Hexavalent chromium and lead were not detecte d
above screening levels in the deeper soil samples collected from these borings.

EEC recommends additional soil sampling to determine the horizontal extent of the contamination followed by excavation of impacted soil.

This report is to present the results of our geophysical survey carried over portions of property located at 17631 Cameron Lane in Huntington Beach, California (Figure 1), on Apr il 13th, 2020. Purpose of the survey was to locate and identify, insofar as possible, the existence of any underground storage tanks (USTs), backfilled excavations, piping, conduit, and other buried features that ma y exist within the survey area. The secondary purpose of the survey was to locate and identify, insofar as po ssible, piping, conduit, and other buried utilities that may exist in the vicinity of eight (8) specific locations for guidance in future drilling activities.

A combination of electromagnetic induction (EM), magnetometry, and ground penetrating radar (GPR) were applied to the search. A utility locator with line tracing capabilities was also brought to the field and used where risers exist onto which a signal could be impressed and traced.

Huntington Beach, California
Project Number: 20-164
Survey Design – The area to be surveyed, along with the specific borehole locations, were indicated in the field by the client. The magnetic gradiometer, line tracer, EM61, M- Scope and GPR were traversed systematically, access permitting, in many directions over the survey area. Additional traverses were taken, access permitting, for detailing and confirmation where anomalous conditions were found. Multiple GPR profiles were also collected throughout the area and in specific areas for confirmation where other instruments detected anomalies.

The line tracer was also used to trace out all detectable utilities in the area.

A rectilinear grid was established over the designated area to guide the acquisition of recorded data. The grid measured 240 feet wide and 125 feet long. The EM61 was then used to collect EM data at 0.66 foot intervals along north-south trending grid lines spaced 5.0-feet apart. This data was then downloaded for further analysis where anomalous conditions were encountered.

Additionally, these instruments were traversed systematically over each borehole along the eight lines of the standard search pattern (Figure 2), wherein, there are two sets of three parallel lines, mutually orthogonal, and two diagonals, all centered on the marked drill location. Adjac ent parallel lines are approximately 5 feet apart, and each line is approximately 20 feet long, access permitting. Other traverses were taken, access permitting, for detailing and confirmation where anomalous conditions were found.

Figure 2: Standard search pattern around target

The line tracers were used to impress signals onto pipes, gener ally through accessible risers and tracer wires when present, to delineate the lines’ locations and orientations. The instruments were also used in passive mode, configured to detect 60 Hz electrical signals and other common radio-frequency signals.

A Geonic’s model EM61 and a Fischer M-Scope was used for the EM sampling. A Sensors and Software Noggin Ground Penetrating Radar unit with a 500 MHz antenna pro duced the radar images. The magnetic gradiometer was a Schonstedt GA-52, and a Metrotech 9890 and RI DGID SR-60 SeekTech utility locator rounded out the tools applied.

Brief Description of the Geophysical Methods Applied - The line locator is used to passively detect energized high voltage electric lines and electrical conduit (50-60 Hz), VLF signals (14-22 kHz), as well as to actively trace other utilities. Where risers are present, the utility l ocator transmitter can be connected directly to the object, and a signal (9.8-82 kHz) is sent traveling along the c onductor, pipe, conduit, etc. In the absence of a riser, the transmitter can be used to impress an input signal on the utility by induction. In either case, the receiver unit is tuned to the input signal, and is used to actively trace the signal along the pipe’s surface projection.

The magnetic gradiometer has two flux gate magnetic fixed senso rs that are passed closely to and over the ground. When not in close proximity to a magnetic object, that is, only in the earth's field, the instrument emits a sound signal at a low frequency. When the instrument passes over a buried iron or steel object, so that locally there is a high magnetic gradient, the frequency of the emitted sound increases. The frequency is a function of the gradient between the two sensors.

The EM61 instrument is a high resolution, time-domain device fo r detecting buried conductive objects. It consists of a powerful transmitter that generates a pulsed prim ary magnetic field when its coils are energized, which induces eddy currents in nearby conductive objects. The decay of the eddy currents, following the input pulse, is measured by the coils, which in turn serve as receiver coils. The decay rate is measured for two coils, mounted concentrically, one above the other. By making the meas urements at a relatively long time interval (measured in milliseconds) after termination of the primary pul se, the response is nearly independent of the electrical conductivity of the ground. Thus, the instrument is a super-sensitive metal detector. Due to its unique coil arrangement, the response curve is a single well-defined positive peak directly over a buried conductive object. This facilitates quick and accurate location of targets.

The GPR instrument beams energy into the ground from its transducer/antenna, in the form of electromagnetic waves. A portion of this energy is reflected back to the anten na at a boundary in the subsurface across which there is an electrical contrast. The instrument produces a continuous record of the reflected energy as the antenna is traversed across the ground surface. The greater the electrical contrast, the higher the amplitude of the returned energy. The radar wave travels at a velocity unique to the material properties of the ground being investigated, and when these velocities are known, the two-way travel times c an be converted to depth. The depth of penetration and image resolution produced are a function of gro und electrical conductivity and dielectric constant.

The M-Scope device energizes the ground by producing an alternating primary magnetic field with AC current in a transmitting coil. If conducting materials are within the area of influence of the primary field, AC eddy currents are induced to flow in the conductors. A receiving co il senses the secondary magnetic field produced by these eddy currents, and outputs the response to a meter in the form of ground conductivity values for the M- Scope. The strength of the secondary field is a function of the conductivity of the object, say a pipe, tank or cluster of drums, its size, and its depth and position relative to the instrument's two coils. Conductive objects, to a depth of approximately 7 feet for the M-Scope are sensed. The devices are also somewhat focused; that is, they are more sensitive to conductors below the instrument than they are to conductors off to the side.

Interpretation and Conclusions - The interpretation took place in real time as the survey progre ssed, and accordingly, the findings of our investigation were marked on the ground cover with spray marking paint at the site and further documented with a Site Interpretation Map with EM data (Figure 3), and site photographs (Figures 4-13).

Piping and utilities detected during the survey were marked with spray marking paint on the ground cover using red for electric, blue for water and yellow for gas. Pink paint was used to highlight metal junk debris (Figure 8).

The EM data shows numerous underground metallic anomalies spread over the property. Some of these anomalous features are linear in fashion while other anomalies were localized and appear to be one single object.

After further investigation using geophysical instrumentation the linear features were found to be former or active utility lines; while the higher EM signatures (centered at X=90, Y=90; and X=150, Y=5) were caused by small metal junk debris.

Once all detectable buried cultural objects were marked and acc ounted for, our findings were discussed in the field with the client at the conclusion of the survey. Each borehole was then marked cleared by Subsurface Surveys and Associates with a white circle, orange pin flag and a yellow “SSS”. Please use the graphics along with the markings in the field for a better representation of our findings.

Limitations and Further Recommendations - It should be understood that limitations inherent in geophysical instruments and/or surveying techniques exist at all sites, and nearly all sites exhibit conditions under which instruments might not perform optimally. Consequently, the detection of buried objects in all circumstances cannot be guaranteed . Such limitations are numerous and include, but are not limit ed to, rebar-reinforced ground cover, abrupt changes in ground cover type, above-ground obstacles preventing full traverses or traverses in one direction only, above-ground conductive objects interfering with instrument signal, nearby powerlines or EM transmitters, highly conductive background soil conditions, limiting GPR penetration, non-metallic targets, shallower or larger objects shielding deeper or smaller targets, tracing signal jumping from one line to another, and inaccessible risers, cleanouts, valve boxes, and manholes. If one or more geophysical instrument is rendered ineffective and cannot be utilized, the quality of the survey can be somewhat degraded.

For the above reasons, and in the interest of maximum safety, w e encourage our clients to take advantage of Underground Service Alert (USA), Dig Alert, or other similar se rvices, when possible. Furthermore, we recommend hand-auguring and the use of a drilling method known as air knifing and vacuum extraction, when feasible or if applicable to this project. These methods may s ignificantly limit damage to underground pipes, conduits, and utilities that might not have been detectable during the course of this survey. Please bear in mind, that geophysical surveying is only one of several levels of protection that is available to our clients.

SubSurface Surveys may include maps in some reports. While they are an accurate general representation of the site and our findings, they are not of engineering quality (i.e., measured and mapped by a licensed land surveyor).

SubSurface Surveys and Associates makes no guarantee either exp ressed or implied regarding the accuracy of the findings and interpretations present. And, in no event will SubSurface Surveys and Associates be liable for any direct, indirect, special, incidental, or consequential dam ages resulting from interpretations and opinions presented herewith.

All data acquired in these surveys are in confidential file in this office, and are available for review by your staff, or by us at your request, at any time. We appreciate the opportunity to participate in this project. Please call, if there are questions.
