SECTION B. EXECUTIVE SUMMARY

1. Summary of Activities Associated with Current TA 

WithersRavenel, Inc. (WR) sampled monitoring wells MW‐1, MW‐2, MW‐3, MW‐7, and MW‐8 at 
the Foothills Service Center site located at 312 East Union Street in Morganton, Burke County, 
North Carolina in association with task authorization TA‐02 under North Carolina Department of 
Environmental Quality (NCDEQ) Contract #N70522‐C.  

2. Soil, Groundwater and LNAPL Assessment Information 

Soils 
During the installation of monitoring well MW‐8 on February 2, 2023, WR collected a risk‐based 
soil sample from the interval below the fill and above the water table identified as SB‐1 (20‐25). 
This soil sample contained naphthalene above the Industrial/Commercial Maximum Soil 
Contaminant Concentration (MSCC) and several compounds above the Soil‐to Groundwater and 
Residential MSCCs. In addition, as part of a potential property transaction, S&ME advanced 
fourteen soil samples throughout the site and on the adjacent property. The soil samples collected 
in the vicinity of the former underground storage tank (UST) system exhibited concentrations 
above the Soil‐to‐Groundwater and Residential MSCCs, but not the Industrial/Commercial 
MSCCs. These soil samples were collected between 15 and 25 feet below ground surface. 

Groundwater  
WR collected samples from groundwater monitoring wells MW‐1 through MW‐3 and MW‐7 and 
MW‐8 on April 17, 2023.  The groundwater samples were submitted for laboratory analysis of 
volatile organic compounds (VOCs) by SM 6200B. 

Laboratory analysis of the groundwater samples collected from MW‐1, MW‐7, and MW‐8 
indicated benzene above the Gross Contamination Levels for Groundwater (GCLs) and MW‐1 and 
MW‐7 had 1,2‐dibromoethane above the GCL. Monitoring well MW‐2 contained one or more 
petroleum compounds above the North Carolina 2L Groundwater Quality Standards (2L 
Standards). Monitoring well MW‐3 did not indicate compounds above the laboratory detection 
limits. 

Liquid Non‐Aqueous Phase Liquid 
Light non‐aqueous phase liquid (LNAPL) was not detected during the April 17, 2023 sampling 
event. LNAPL has historically been detected in monitoring well MW‐1. 

3.       Receptor Information 

The area within 1,500‐feet of the subject property is supplied potable water by the Town of 
Morganton Municipal Water System.  WR is not aware of any surface water bodies within 500‐
feet of the subject property.

4. Remediation Activities 

Based on WR’s review of historical files available for the site, the following remedial activities have 
been completed at the site: 
 Six 560‐gallon USTs, one 1,000‐gallon UST, one 1,200‐gallon UST, and one 2,000‐gallon UST 
were removed from the subject property on March 23‐31, 2020. A total of 828.99 tons of 
petroleum‐impacted soil were removed the property during the UST removal.   
 In January 2022, WR conducted a Mobile Multi‐Phase Extraction (MMPE) event at the site 
utilizing MW‐1. During the MMPE event, eight gallons of LNAPL and 2,206 gallons of VOC‐
impacted water were recovered and transported offsite for disposal. Based on mass removal 
calculations, 1,083.28 pounds of VOCs or 176.09 gallons of VOCs were removed as vapor 
during the event.   
 WR conducted two air sparge enhanced MMPEs (AS/MMPEs) in March 2023, one the week 
of March 6, 2023 and one the following week. In completion of the AS/MMPE events, a total 
of 9,121‐gallons of contaminated water was recovered and based on mass removal 
calculations, a total of 1,171.24‐pounds or 190.39‐gallons of volatile organic compounds 
(VOCs) were removed as vapor.     

5. Recommendations 
Based on the results of the activities conducted at the site in association with this TA, WR 
recommends the following: 
 Evaluating remedial options after the in situ Chemical Oxidation bench scale testing results 
for the A.G. Jobe site (NCDEQ Incident #30075) are received.

SECTION C. SITE HISTORY AND CHARACTERIZATION

The following information summarizes the site history and characterization.   

1. UST Information 
In September 2000, seven USTs (UST‐1 through UST‐6, and UST‐9) were emptied and closed in 
place using foam.  In January 2020, WR conducted a ground‐penetrating radar (GPR) survey to 
identify the locations of the closed‐in‐place USTs. In March 2020, WR completed the closure by 
removal of the UST systems which included six 560‐gallon USTs, one 1,000‐gallon UST, one 
1,200‐gallon UST, and one 2,000‐gallon UST.  Information regarding the USTs is summarized on 
Table B‐1. 

2.       Description of Release/General Assessment History 
The following summary of the assessment history is based on WR’s review of historical files for 
the subject incident: 
February 1997 ‐ Phase II–Abandoned UST Study, LAW Engineering and Environmental Services, 
Inc. (LAW)   
LAW completed underground locating and confirmed the presence of five USTs, one UST was 
present in one tank basin and the remaining four identified USTs were in an additional tank basin.  
LAW collected soil samples around the two UST basins. Results indicated the presence of TPH‐
GRO exceeding the current NCDEQ Action Level in four of the seven soil samples collected.  The 
groundwater samples collected from the soil borings indicated the presence of impacts above the 
2L Standards in each of the six samples with the GCL for benzene exceeded in four of the six 
groundwater samples.  LAW personnel did not identify water supply wells on the site or adjacent 
properties and the area is served by municipal water.   

September 2000 – UST Removal and Abandonment, Royster Oil Company, Inc. (Royster)   
Royster abandoned‐in‐place seven USTs using foam and removed one 550‐gallon UST in the 
triangle formed by the intersection of Lenoir Street and East Union Street.  

February 2020 – Initial Groundwater Monitoring Report (WR) 
WR performed a GPR survey and collected soil and groundwater samples. The GPR survey 
identified five USTs at the site. Soil sampling indicated the petroleum release appears to be 
concentrated near the former dispenser island and its adjacent tanks and that soil contamination 
extends to the groundwater table at approximately 25 feet bgs. The groundwater plume appears 
to be primarily concentrated near the dispenser island.  

May 2020 – Initial Abatement Action Report (WR) 
WR supervised the removal of nine USTs consisting of six 560‐gallon USTs, one 1,000‐gallon UST, 
one 1,200‐gallon UST, and one 2,000‐gallon UST between March 23 and 31, 2020. Two additional 
USTs were identified during the UST removal activities in the UST basin previously thought to 
contain one UST. A total of 828.99 tons of petroleum‐impacted soils were removed from the site

during the UST closure activities and transported off‐site for treatment and disposal.  Exceedances 
of the Soil‐to‐Groundwater and Residential MSCCs were observed in the soil samples collected 
from Excavation 1 and Excavation 4.  Excavation 1 encompassed the dispensers and USTs 1 
through 4 and extended to approximately 18‐20 feet bgs and Excavation 4 included USTs 7, 8 and 
9 and extended to approximately 7 feet bgs.  

September 2020 – Subsequent Monitoring Report (WR) 
WR installed and collected samples from monitoring wells MW‐1 through MW‐3 on July 14, 2020.  
The groundwater sample collected from monitoring well MW‐1 indicated benzene and EDB above 
the GCL. Multiple contaminants were identified above the 2L Standards in monitoring wells MW‐
1 through MW‐3. LNAPL was not observed in the site monitoring wells.  The groundwater flow 
direction was determined to be to the south, generally towards an unnamed tributary of Hunting 
Creek approximately 920 feet to the southeast.   

February 2021 – Annual Monitoring Report (WR) 
WR collected samples from monitoring wells MW‐1 through MW‐3 on January 20, 2021.  The 
groundwater sample collected from monitoring well MW‐1 indicated benzene and EDB remained 
above the GCL. Multiple contaminants were identified above the 2L Standards in monitoring wells 
MW‐1 through MW‐3. LNAPL was not observed in the site monitoring wells.   

August 2021 – Corrective Action Feasibility Study (WR) 
Based on the observed soil and groundwater concentrations, LNAPL was determined to likely be 
present at the site. Therefore, WR recommended a surfactant‐enhanced injection and MMPE 
event. Since EDB was not likely to be addressed by this approach, WR recommended treating the 
remaining contaminant mass via a carbon‐based injection such as Trap & Treat BOS 200®, 
PetrofixTM, or similar injectates.  

March 2022 – Subsequent Monitoring Report (WR) 
On January 24 through 28, 2022, WR supervised a MMPE event. Prior to the MMPE event, the 
depth to LNAPL and groundwater measurements in MW‐1 were 27.60 feet below the top of 
casing (ft‐BTOC) and 27.99 ft‐BTOC, respectively, for a LNAPL thickness of 0.39 feet. During the 
radius of influence gauging conducted on January 28, 2022, as part of the MMPE event, LNAPL 
was detected in monitoring well MW‐2 at a thickness of 0.07 feet. Approximately eight gallons of 
LNAPL and 2,206 gallons of VOC‐impacted water were recovered and transported offsite for 
disposal. Based on mass removal calculations, 1,083.28 pounds of VOCs or 176.09 gallons of 
VOCs were removed as vapor during the event.   
WR mobilized to the site on March 2, 2022 to sample three Type II groundwater monitoring wells. 
Monitoring well MW‐1 contained LNAPL at a thickness of 0.41 feet and was not sampled. 
Laboratory analysis of the groundwater samples collected from monitoring wells MW‐2 and MW‐
3 identified one or more petroleum compounds above the 2L Standards, but not the GCLs.

March 2023 – Groundwater Monitoring Report (WR) 
WR supervised the installation of two monitoring wells, sampled the five monitoring wells at the 
site, and installed one 4” remediation well and three 2” air sparge wells. During the installation of 
monitoring well MW‐8 on February 2, 2023, WR collected a risk‐based soil sample from the 
interval below the fill and above the water table identified as SB‐1 (20‐25). This soil sample 
contained naphthalene above the Industrial/Commercial MSCC and several compounds above the 
Soil‐to Groundwater and Residential MSCCs.  
Laboratory analysis of the groundwater samples collected from MW‐7 indicated benzene and 1,2‐
dibromoethane above the GCLs and MW‐8 had benzene above its GCL. Monitoring wells MW‐2, 
MW‐3, MW‐4, MW‐7, and MW‐8 detected one or more petroleum compounds above the 2L 
Standards.  
On February 27, 2023, WR personnel along with Geologic Exploration (GEX) mobilized to the site 
to install one 4‐inch groundwater recovery well and three 2‐inch air sparge wells via hollow stem 
auger. The 4‐inch diameter recovery well was installed to a depth of 40 feet with 15 feet of screen. 
The 2‐inch diameter air sparge wells were installed to depths of 40 feet each with five feet of 
screen. The well construction records from GEX are included in Appendix A as they were not 
submitted by GEX prior to submittal of the Groundwater Monitoring Report dated March 30, 
2023. 

April 2023 – Letter Report – MMPE Events (WR) 
WR mobilized to the subject site on March 6, 2023 and March 13, 2023, for the purposes of 
performing two AS/MMPE events on select monitoring wells and recovery well RW‐1 and utilizing 
air sparge wells AS‐1, AS‐2, and AS‐3 for air injection. Throughout the course of the AS/MMPE 
events, effluent emissions ranged from 8,000 parts per million (ppm) to 100,000 ppm. In 
completion of the AS/MMPE events, a total of 9,121‐gallons of contaminated water was 
recovered and based on mass removal calculations, a total of 1,171.24‐pounds or 190.39‐gallons 
of volatile organic compounds (VOCs) were removed as vapor.

5.       Regional and Site Geology and Hydrology 
The Geologic Map of North Carolina (Department of Natural Resources, Division of Land 
Resources, North Carolina Geologic Survey, 1985) shows materials underlying the site to consist 
of “migmatitic granitic gneiss” of Cambrian‐Ordovician age, within intrusive rocks of the Inner 
Piedmont, Chauga Belt, Smith River Allochthon, and Sauratown Mountain Belts.  Base materials at 
the site location are indexed as “foliated to massive, granitic to quartz dioritic; biotite gneiss and 
amphibolite common.”  The site is adjacent to what is mapped as “biotite gneiss and schist” of Late 
Proterozoic‐Cambrian age, with metamorphic rocks of the Inner Piedmont, Chauga Belt, Smith 
River Allochthon, and Sauratown Mountain Belts. Base materials in this area are indexed as 
“inequigranular, locally abundant potassic feldspar and garnet; interlayered and gradational with 
calc‐silicate rock, sillimanite‐mica schist, and amphibolite and contains small masses of granitic 
rock.”  
According to the United States Department of Agricultural (USDA) Natural Resources 
Conservation Service (NRCS) Web Soil Survey, the source area is underlain by urban land soils. 
Urban land is defined as impervious layers over human‐transported material. Boring log and 
excavation records from the site indicate that the general lithology of the site soils consists of 
micaceous silts and clayey silts.   

SECTION D. GROUNDWATER SAMPLING – APRIL 2023
WR mobilized to the site on April 17, 2023, to sample monitoring wells MW‐1 through MW‐3 and 
MW‐7 and MW‐8. The locations of monitoring wells MW‐1 through MW‐8 are shown on Figure 
2. 
Prior to purging activities, groundwater levels were gauged with a decontaminated electronic oil‐
water interface meter. Groundwater levels measured within the monitoring wells ranged from 
25.71 ft‐BTOC in monitoring well MW‐8 to 26.70 ft‐BTOC in monitoring well MW‐3. The 
monitoring wells were screened across the water table. Groundwater elevations were utilized to

generate a groundwater flow map at the site, based on the April 2023 groundwater levels (Figure 
3).  Groundwater elevation data indicated that groundwater flows to the southeast in the vicinity 
of the source area.  Groundwater elevations and well construction information is summarized in 
Table B‐7. Historical groundwater elevations and LNAPL thicknesses are included in Table B‐9. 
After gauging, the monitoring wells were purged a minimum of three volumes of groundwater 
using dedicated bailers.  Groundwater samples were then placed directly into laboratory‐provided 
containers, placed on ice, and under property chain‐of‐custody procedures, transported to 
Waypoint Analytical, Inc. located in Charlotte, NC, to be analyzed for VOCs by SM6200B. 
Laboratory Results 
Laboratory analysis of the groundwater samples collected from MW‐1, MW‐7, and MW‐8 
indicated benzene above the GCLs and MW‐1 and MW‐7 had 1,2‐dibromoethane above the GCL. 
Monitoring well MW‐2 contained one or more petroleum compounds above the 2L Standards. 
Monitoring well MW‐3 did not indicate compounds above the laboratory detection limits. 
A summary of the groundwater analytical results is presented in Table B‐4 and shown on Figure 
4. A benzene isoconcentration map is included as Figure 5. A photographic record and the field 
notes are included in Appendix B.  A copy of the laboratory analytical report and chain‐of‐custody 
is included in Appendix C.  WR’s standard operating procedures are provided in Appendix D. 

SECTION E. CONCLUSIONS AND RECOMMENDATIONS
This report documents the results of field activities conducted at the site for TA‐02, which included 
a limited groundwater sampling event which included monitoring wells MW‐1, MW‐2, MW‐3, 
MW‐7, and MW‐8. Conclusions based on observations, analytical data and research relating to 
the release at the site combined with historical information include the following: 
 The soil remedial goals for the site are the Industrial/Commercial MSCCs. A soil sample 
collected in February 2023 contained naphthalene above the Industrial/Commercial MSCC.  
 The groundwater remedial goals are the GCLs. Laboratory analysis of the groundwater 
samples collected from MW‐1, MW‐7, and MW‐8 indicated benzene above the GCLs and 
MW‐1 and MW‐7 had 1,2‐dibromoethane above the GCL.  
 The site is currently utilized as a parking lot by the City of Morganton. 
 Contaminant concentrations in monitoring well MW‐2 did not exceed the GCLs. 
 Monitoring well MW‐3 did not exhibit concentrations exceeding the laboratory detection 
limits. 
Based on the results of assessment and monitoring activities conducted at the site in association 
with this TA, WR recommends the following: 
 Evaluating remedial options after the in situ Chemical Oxidation bench scale testing results 
for the A.G. Jobe site (NCDEQ Incident #30075) are received.

Dear Liz Allyn:
Waypoint Analytical, LLC (Charlotte) received sample(s) on 4/21/2023 for the analyses presented in the following report.
The above referenced project has been analyzed per your instructions. The analyses were performed in
accordance with the applicable analytical method.
The analytical data has been validated using standard quality control measures performed as required by the analytical method. Quality Assurance, method validations, instrumentation maintenance and calibration for all
parameters were performed in accordance with guidelines established by the USEPA (including 40 CFR 136 Method Update Rule May 2021) unless otherwise indicated. Certain parameters (chlorine, pH, dissolved oxygen, sulfite...) are required to be analyzed within 15 minutes of
sampling. Usually, but not always, any field parameter analyzed at the laboratory is outside of this holding time. Refer to sample analysis time for confirmation of holding time compliance.
The results are shown on the attached Report of Analysis(s). Results for solid matrices are reported on an as-
received basis unless otherwise indicated. This report shall not be reproduced except in full and relates only to the samples included in this report. Please do not hesitate to contact me or client services if you have any questions or need additional information.
Sincerely,
Angela D Overcash Senior Project Manager

Our People. Your Success.
Soil Sampling, Soil Boring and Monitor Well Installation, Well Development Soil borings are installed utilizing a stainless-steel hand auger, direct-push hydraulic drill or auger rotary
drill using either a macro core™ sampler, hollow stem augers, or air rotary roller cone bit. Soil borings are
typically sampled at discrete intervals from the bucket of a clean stainless steel hand auger, direct push stainless steel sampler with acetate sleeve, or a split barrel sampler. When appropriate, soil samples may be collected from drill cuttings associated with the boring or well installation. Monitor wells are constructed within select soil borings of one, two, or four-inch inside diameter PVC
casing and machine slotted screen in accordance with NCAC Title 15A, Subchapter 02C (Well Construction Standards, Criteria and Standards Applicable to Water Supply and Certain Other Wells). Clean-washed “#2 Torpedo Sand” is typically utilized to fill the boring annulus surrounding the well screen, extending to a minimum of 1-foot above the well screen. A minimum 1-foot thick bentonite clay seal is emplaced above the sand pack and hydrated. Neat cement grout is placed in the remaining annulus
space from the upper portion of the bentonite seal to within 1-foot of surface grade. In coastal plain areas where shallow groundwater is encountered, a variance to construction standards may be employed to ensure the upper portion of the well screen intersects the upper aquifer surface. Wellheads may be completed with either concrete-set flush mounted traffic-bearing steel skirted manholes with bolt down covers or steel above-ground “stick-up” well protectors set in a concrete pad. The monitoring wells are
secured with locking caps. Temporary wells or piezometers may be completed with the PVC riser cut at or above grade, and are abandoned within 24-hours of their installation. Wells may be developed using a bailer, electric submersible pump, pneumatic pump, or peristaltic pump, dependent upon site conditions. When wells are developed by the driller, they may be developed with
any of the methods outlined above, in addition to air or water injection. Soil boring logs and well construction details are typically prepared for presentation in a report appendix. Borings completed in bedrock may be drilled using air rotary, coring, or sonic drilling methods. Groundwater Depth to Water Measurements

Groundwater level measurements are typically obtained using an electronic water level indicator which registers a tone and/or illuminated light when the probe contacts groundwater. Depth to groundwater measurements are obtained by lowering the probe attached to a cable usually marked in 0.01 foot intervals into the well until the probe of the meter intersects the water surface. The measurement from
the top of the riser pipe or top of casing (TOC) to the water level is recorded to the nearest 0.01 foot. The
electronic water level indicator probe and exposed probe cable is decontaminated between measurement locations.

Free Product Level Measurements Light Non-Aqueous Phase Liquid (LNAPL) or “free product” present on the water table is measured using
an electronic oil/water interface probe. The interface probe has both an audible and illuminating light
that indicate when a liquid level is encountered. The oil/water interface probe registers a solid tone and solidly lit light when LNAPL petroleum product is encountered and a beeping tone flashing light when groundwater is encountered. Depth to LNAPL measurements are obtained by lowering the probe attached to a cable marked in 0.01 foot intervals into the well until the probe of the meter intersects the product or groundwater. The measurements from the top of the riser pipe or TOC to the liquid level are
recorded to the nearest 0.01 foot. The thickness of LNAPL is calculated by subtracting the depth to LNAPL measurement from the depth to groundwater measurement. The electronic interface probe is decontaminated between measurement locations. Soil Sampling and Field Screening
Soil sampling is performed in general accordance with ASTM: 1586-84 where applicable. Sampling procedures are followed to protect the chemical integrity of the soil samples and minimize the potential for cross contamination between sample locations, including discarding of the exterior of the sample which contacts the auger bucket, acetate sleeve, or split barrel sampler, the use of stainless steel sampling
equipment, and the thorough decontamination of sampling apparatus prior to use and between sample locations. Soil samples retained as a part of excavation or other intrusive “digging” activities may be collected from the bucket of excavation equipment or using a hand shovel, if appropriate. Care to collect soil samples
from excavation equipment includes retrieving native soil from material that has not made contact with the excavating equipment. Samples are collected in sealable bags or by directly filling sample containers as described above. Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample
integrity and minimize the potential for cross contamination or field personnel exposure to contaminants.
Sampling equipment such as hand auger extensions and buckets, direct push samplers, split spoons or shovels, are decontaminated prior to their use in the collection of samples. Samples are placed within laboratory grade sample containers provided by the laboratory to which the
samples are submitted, labeled, sealed, and placed in an ice filled cooler. An aliquot of the sample is
typically placed in a clean sealable bag and allowed to reach ambient air temperature for future screening of volatile vapor content with a photoionization detector (PID), flame-ionization detector (FID) or other portable screening device.
Screening of samples with a PID, FID or other field screening device is performed in accordance with
device manufacturer specifications for screening, following calibration of the instrument based on manufacturer recommended procedures.

Groundwater Sampling Groundwater samples are generally collected using one of three standard methods – through the use of a
dedicated, disposable bailer, a peristaltic pump or submersible electric pump.
When sampling with a bailer, a minimum of three well volumes of groundwater are extracted from the well as a means of purging, unless the well is purged to a “dry” state prior to the removal of three volumes of water. Prior to collection of the groundwater sample with the bailer, the water level is allowed to recover to within 80% of the original level measured prior to purging.
When sampling with a peristaltic or submersible electric pump, polyethylene (PE) tubing (or equivalent) is emplaced into the screened section of the monitoring well, and the pump is used to extract water through the tubing. When using the either of these methods, general water quality measurements including but not limited to pH, temperature, dissolved oxygen (DO), oxygen reductive potential (ORP), specific
conductivity and turbidity may be used as methods for determining when an adequate purge of the well has been conducted. When water quality parameters are measured, the resulting data are included in well purge forms or field notes specific to each site and sampling point. Following the purging of three well volumes of groundwater (in the case of the bailed well) or stability of
monitored measurements (in the case of the peristaltic or submersible electric pump), the groundwater sample(s) are introduced directly into sample containers provided by the laboratory to which samples are ultimately submitted for analysis. Any samples requiring chemical preservation are contained in pre-preserved container(s) provided by the laboratory.
Sampling is performed using new, disposable nitrile gloves for each sample location to ensure sample integrity and minimize the potential for cross contamination of samples or field personnel exposure to contaminants. Water Supply Well Sampling

Sampling of water supply wells is accomplished through the collection of a representative sample from an in-line water tap or other point accessible for sampling. Where possible, the sample is collected from a point prior to any filtration or point of entry (POE) system which might be installed on a well. In some cases, samples will be collected from both pre and post-POE locations. Prior to the collection of samples
through an in-place sampling point, the tap or sampling port is cleaned with an Alconox® and deionized
water solution, rinsed with deionized water, and again with an isopropyl alcohol (IPA) rinse. In the case of active supply wells (e.g., a well with a useable well pump with an active power supply), the well pump is energized and allowed to run for a minimum of ten (10) minutes time, after which a sample is
contained in laboratory grade sample containers as described in the previous section. Water quality
parameters may be (but are not necessarily) measured in association with the well purging. Supply wells without active power supplies are not generally sampled, as the well seal cannot be compromised by individuals not certified as a well contractor. However, in the case of a well with no
power supply or pump installed, samples could be obtained through the use of a bailer, peristaltic pump or
electric submersible pump.

Decontamination Procedures Decontamination procedures employed in the performance of field activities will vary dependent upon
the method(s) of sampling performed at any site, but will generally include the following:
• Remove excess soil/sludge from any sampling equipment as needed, • Wash and scrub the equipment with a phosphate-free detergent such as Alconox® or Liquinox® in a contaminant-free tap water solution. Use a brush to remove particulate matter and surface films as necessary,
• Rinse thoroughly with tap water, • Rinse thoroughly with analyte-free water (deionized water),
 Rinse thoroughly with isopropyl alcohol, • Allow the equipment to air dry,
• Prevent inadvertent contamination during storage and transport (accomplished through storage of equipment in foil or plastic bags/sheeting). In the case of disposable bailers and tubing utilized for the purging and sampling of wells, these items may be decontaminated prior to their disposal. In general, no decontamination of these items is necessary
prior to their use in sampling.
