SECTION B. EXECUTIVE SUMMARY 

1. Summary of Activities Associated with Current TA 

WithersRavenel, Inc. (WR) conducted a soil and groundwater sampling event at the J&J Mart site 
located at 905 S. Main St. in Star, Montgomery County, North Carolina in association with TA‐01 
under NCDEQ Contract #N70522‐C.  The scope of work for this project included sampling 
existing monitoring well MW‐1 and conducting soil sampling in the vicinity of the inactive UST 
system.  

2. Soil, Groundwater and LNAPL Assessment Information 

Soils 
Soil samples were obtained from direct‐push boring locations in the vicinity of the 10,000‐gallon 
compartmentalized UST (two 4,000‐gallon gasoline compartments and one 2,000‐gallon diesel 
compartment) on August 25, 2023. Soil samples were collected continuously at four‐foot intervals 
with the exception of the interval collected from 20 to 25 feet below ground surface (bgs). Soil 
samples were screened using a photoionization detector (PID). From each boring, one sample 
between the interval of 0 to 12.5 feet bgs and one sample between the interval of 12.5 and 25 
feet bgs exhibiting the highest PID reading were submitted for analysis by Environmental 
Protection Agency (EPA) Method 8260D. The two soil samples collected from the boring at the 
western end of the UST contained naphthalene above the Residential Maximum Soil Contaminant 
Concentration (MSCC). Three of the borings (a total of four samples) contained compounds above 
the Soil‐to‐Groundwater MSCCs. None of the compounds exceeded the established 
Industrial/Commercial MSCCs.   
Groundwater  
Laboratory analytical results from the August 25, 2023 sampling event revealed the following: 
 Monitoring well MW‐1 contained the following compounds above the Gross 
Contamination Levels (GCLs): benzene at 44,500 micrograms per liter (g/L) and 1,2‐
dibromoethane at 271 g/L.  
 Monitoring well also MW‐1 contained the following compounds above the North Carolina 
Groundwater Quality Standards (2L Standards): 1,2‐dichloroethane (1,2‐DCA) at 322 g/L, 
ethylbenzene at 4,240 g/L, di‐isopropyl ether at 6,290 g/L, isopropylbenzene at 183 
g/L, 2‐hexanone at 355 g/L, methyl tert‐butyl ether (MTBE) at 3,090 g/L, naphthalene 
at 888 g/L, n‐propylbenzene at 421 g/L, toluene at 83,500 g/L, 1,2,4‐trimethylbenzene 
at 3,020 g/L, 1,3,5‐trimethylbenzene at 731 g/L, and total xylenes at 23,500 g/L. 

Light Non‐Aqueous Phase Liquid (LNAPL) 
LNAPL was reportedly detected at a thickness of 4‐inches by a consultant on‐site to provide a 
UST removal quote in 2015.

3.       Receptor Information 

S&ME previously identified ten water supply wells within 1,000 feet of the source area, one of 
which was active, WSW‐6A, located 900 feet west‐northwest of the source area.  Based on the 
information obtained during the updated receptor survey, one active water supply well (WSW‐
6A), one well of unknown usage (WSW‐4), and six inactive wells (WSW‐1, WSW‐2, WSW‐3, 
WSW‐6, WSW‐8, and WSW‐9) were identified. Previously identified water supply wells WSW‐5 
and WSW‐7 were outside the 1,000‐foot radius as determined from the location of MW‐1.   

WR inquired with the Town of Star Public Works Department to obtain information regarding the 
connection status of the properties within 1,000 ft of the site.  The Town of Star indicated that all 
properties within 1,000 feet of the source area were serviced by the municipal water supply and 
they were unaware of in‐use water supply wells in the area.  However, the properties addressed 
on Alma Drive (WSW‐4 and WSW‐5) and Allen Drive (WSW‐6 and WSW‐6A), both of which are 
private roads, do not have municipal connections. The properties where water supply wells WSW‐
4 and WSW‐5 are located are reportedly vacant. Water supply well WSW‐6 went dry and was 
replaced by WSW‐6A which is currently in use.  

Although subsurface utilities were identified in the site vicinity, the depth to water at the site is 
approximately 30 feet below ground surface.  Therefore, these utilities are not expected to be 
pathways for contaminant transport. 

No additional receptors (streams or wetlands) were identified within 500‐ft of the source area.  
There is an unnamed pond approximately 550 feet west of the site. 

The site is not located within a Wellhead Protection Area.     

4. Remediation Activities 

Based on currently available information, WR is unaware of remedial actions that have been 
performed at the site with the exception of the removal of 48 cubic yards of impacted soil during 
the removal of two 1,000‐gallon gasoline USTs.  

5. Recommendations 

Based on the results of assessment and monitoring activities conducted at the site in association 
with this TA, WR recommends the following: 
 Abandon the 10,000‐gallon compartmentalized UST in place due to its proximity to the on‐
site building and previous caving in of soils beneath the on‐site building during the removal 
of two 1,000‐gallon gasoline USTs. 
 Conduct an Aggressive Fluid and Vapor Recovery (AFVR) event on monitoring well MW‐
1. 
 Install two additional monitoring wells to determine groundwater flow direction. 
 Consider replacing MW‐1 as it has a bent casing. 
 Conduct slug testing.

SECTION C. SITE HISTORY AND CHARACTERIZATION 

The following information summarizes the site history and characterization.   

1. UST Information 
In May 1994, during the removal of two 1,000‐gallon gasoline USTs installed in the 1960s, a 
release was discovered. This release is associated with Smith & Son Garage (NCDEQ incident 
number 14008). In September 1995, two 10,000‐gallon gasoline USTs installed in approximately 
1976 were removed from the site. A release was not identified during the removal of the two 
10,000‐gallon gasoline USTs. In December 1995, one 10,000‐gallon compartmentalized UST was 
installed in the vicinity of the former UST excavation areas. In 2015, while conducting a site visit 
to prepare a UST removal quote, Blue Ridge Environmental Services discovered four inches of 
LNAPL in monitoring well MW‐1. The presence of LNAPL was considered to be a new release and 
was assigned NCDEQ Incident #29956 (J&J Mart). A small AST was observed during the site 
reconnaissance activities in July 2016.  However, this AST was no longer present during WR’s site 
visit in June 2021. 
The site location is shown on Figure 1. Figure 2 shows the location of the historical and current 
UST systems. Historical UST and AST information is provided in 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 including: 
• UST Closure Report and Soil Test Results (August 30, 1994) by Environmental Engineering 
Services. 
This report was prepared to document the removal of two 1,000‐gallon gasoline USTs for the 
Smith & Sons Garage (NCDEQ Incident #14008). Samples collected from beneath the USTs 
showed considerable levels of hydrocarbon contamination. TPH‐GRO concentrations ranged 
from non‐detect to 15,000 mg/kg and TPH‐DRO ranged from non‐detect to 1,710 mg/kg. 
During the removal of the impacted soils, caving of soils beneath the garage building prevented 
additional excavation. Approximately 48 cubic yards of impacted soil was stockpiled. The tank 
pit was backfilled with clean soils. 
• Site Reconnaissance and Receptor Survey (December 1, 2016) by S&ME. 
This report documented the results of a receptor survey conducted in July 2016.  The receptor 
survey identified ten water supply wells (WSW‐1 through WSW6, WSW‐6A, and WSW‐7 
through WSW‐9) within 1,000 feet of the site with one of the water supply wells being active 
(WSW‐6A).  The report indicated municipal water was available to the properties within 1,000 
feet of the source area.  
• Geophysical Survey Report (August 16, 2017) by S&ME.  
S&ME completed a geophysical survey using time domain electromagnetics (TDEM) and 
ground penetrating radar (GPR) to accurately locate the UST to determine if removal is

possible. The existing 10,000‐gallon UST was located and pea gravel was determined to be in 
the tank pit and was identified within four feet of the building. Based on the proximity of the 
UST to the building, S&ME recommended abandoning the UST in place.  
• Receptor Survey Update Letter Report (August 13, 2021) by WR.  
WR completed an updated receptor survey in July 2021. The Town of Star Public Works 
Department indicated that all properties within 1,000 feet of the site are serviced by the 
municipal water supply. WR determined that the properties located on Alma Drive (WSW‐4 
and WSW‐5) and Allen Drive (WSW‐6 and WSW‐6A), both of which are private roads, do not 
have municipal connections. The properties where WSW‐4 and WSW‐5 are located are 
reportedly vacant. Water supply well WSW‐6 went dry and was replaced by WSW‐6A which 
is currently in use.  
• UST Abandonment Bid Requests (January 31, 2022) by WR.  
WR prepared a bid request for the abandonment‐in‐place of the 10,000‐gallon 
compartmentalized UST located adjacent to the site building. Due to the potential for 
contamination to exist beneath the pump island, based on observed contaminant 
concentrations in monitoring well MW‐1, WR attempted to contact the property owner 
regarding the removal of the canopy associated with the pump island. However, WR could not 
reach the property owner. 

3.  Brief Description of Site Characteristics 
The property is located at 905 South Main Street in Star, Montgomery County, North Carolina 
(Figure 2). Site photographs are included in Appendix A. The property includes a single‐story slab‐
on‐grade concrete block structure, reportedly constructed in 1950.  The site is currently operating 
as Tienda Estrellita, a retail clothing store.  In addition, the rear of the site is used for pallet 
breakdown and storage.            
Surface coverings at the location include the site structure, concrete, and gravel areas 
(approximately 30% of the area) and grassy areas (approximately 70%). The NC PIN for the 
property is 7569 00 74 8767 and the site is approximately 1.65‐acres.   
Surface drainage through the area generally follows topography or is channeled through wet 
weather ditches running parallel to South Main Street.  At the site location, surface drainage flows 
to the east‐northeast.     

4.       Information on Receptors/Potential Receptors 
S&ME previously identified ten water supply wells within 1,000 feet of the source area, one of 
which was active, WSW‐6A, located 900 feet west‐northwest of the source area.  Based on the 
information obtained during the updated receptor survey, one active water supply well (WSW‐
6A), one well of unknown usage (WSW‐4), and six inactive wells (WSW‐1, WSW‐2, WSW‐3, 
WSW‐6, WSW‐8, and WSW‐9) were identified. Previously identified water supply wells WSW‐5 
and WSW‐7 were outside the 1,000‐foot radius as determined from the location of MW‐1.   

WR inquired with the Town of Star Public Works Department to obtain information regarding the 
connection status of the properties within 1,000 ft of the site.  The Town of Star indicated that all 
properties within 1,000 feet of the source area were serviced by the municipal water supply and

they were unaware of in‐use water supply wells in the area.  However, the properties addressed 
on Alma Drive (WSW‐4 and WSW‐5) and Allen Drive (WSW‐6 and WSW‐6A), both of which are 
private roads, do not have municipal connections. The properties where water supply wells WSW‐
4 and WSW‐5 are located are reportedly vacant. Water supply well WSW‐6 went dry and was 
replaced by WSW‐6A which is currently in use. Water supply well information is provided on Table 
B‐5A, while locations of the wells are shown on Figure 3.  

Although subsurface utilities were identified in the site vicinity, the depth to water at the site is 
approximately 30 feet below ground surface.  Therefore, these utilities are not expected to be 
pathways for contaminant transport. 

No additional receptors (streams or wetlands) were identified within 500‐ft of the source area.  
There is an unnamed pond approximately 550 feet west of the site. 

The site is not located within a Wellhead Protection Area.     

Examination of the U.S. Geological Survey 7.5‐minute series topographic maps of Star and Biscoe 
North Carolina Quadrangles, the site is located approximately 610 feet above mean sea level with 
a topographic relief to the east‐northeast, towards Cotton Creek approximately 1,200 feet from 
the source area (Figure 1).   

5.       Regional and Site Geology and Hydrology 
The site is located within the Piedmont Physiographic Province of North Carolina. More 
specifically, the site is underlain by the Carolina Slate Belt composed of metamorphosed argillite, 
mudstone, volcanic sandstone, conglomerate, and volcanic rock of the Cambrian/Late Proterozoic. 
According to the United States Department of Agricultural (USDA) Natural Resources 
Conservation Service (NRCS) Web Soil Survey, the source area is underlain by the Georgeville‐
Urban land complex (2 to 10 percent slopes).  Georgeville‐Urban land complex is well drained,

SECTION E. GROUNDWATER SAMPLING – AUGUST 2023 

On August 25, 2023, WR personnel mobilized to the subject property to gauge, purge, and sample 
of monitoring well MW‐1. The following paragraphs describe the sampling activities and 
associated laboratory analytical results.  

Groundwater Sampling Activities 
Prior to the purging and sampling of the site monitoring well as described below, WR personnel 
gauged the well with an electronic oil‐water interface meter to determine the depth to LNAPL and 
groundwater.  During the performance of these activities, LNAPL was not identified in MW‐1.     
The depth to groundwater measurement in monitoring well MW‐1 was 38.94 feet below the top 
of casing (ft‐BTOC). The casing was bent in MW‐1 and a bailer designed for a 1” well was necessary 
to purge and collect groundwater samples. Groundwater elevation measurements for this event 
are presented in Table B‐7.   Field notes are included in Appendix A. 
Following gauging, monitoring well MW‐1 was purged and sampled with a disposable polyethylene 
(PE) bailer.  The sample was decanted into pre‐preserved laboratory provided sample containers 
and submitted to Waypoint Analytical, LLC for testing by Standard Method (SM) 6200B. 

Laboratory Results 
Laboratory analytical results from the August 25, 2023 sampling event revealed the following: 

 Monitoring well MW‐1 contained the following compounds above the GCLs: benzene at 
44,500 g/L and 1,2‐dibromoethane at 271 g/L.  
 Monitoring well also MW‐1 contained the following compounds above the 2L Standards: 
1,2‐DCA at 322 g/L, ethylbenzene at 4,240 g/L, di‐isopropyl ether at 6,290 g/L, 
isopropylbenzene at 183 g/L, 2‐hexanone at 355 g/L, MTBE at 3,090 g/L, naphthalene 
at 888 g/L, n‐propylbenzene at 421 g/L, toluene at 83,500 g/L, 1,2,4‐trimethylbenzene 
at 3,020 g/L, 1,3,5‐trimethylbenzene at 731 g/L, and total xylenes at 23,500 g/L. 

Groundwater analytical results are summarized in Table B‐4 and shown on Figure 5.   
Copies of the laboratory analytical report and chain‐of‐custody are included in Appendix C.  WR’s 
generalized standard operating procedures are provided in Appendix D.

SECTION F. CONCLUSIONS AND RECOMMENDATIONS 

This report documents the results of field activities conducted at the site for TA‐01, which included 
advancing five soil borings to a depth of 25 feet bgs each and gauging, purging and sampling 
monitoring well MW‐1. Conclusions based on observations, analytical data and research relating 
to the release at the site combined with historical information include the following: 

 The site is currently operating as Tienda Estrellita, a retail clothing store.  In addition, the 
rear of the site is used for pallet breakdown and storage.            
 Ten water supply wells were identified within 1,000 feet of the site (WSW‐1 through 
WSW‐6, WSW‐6A, and WSW‐7 through WSW‐9).  Municipal water is available in the site 
and surrounding area.  
 The soil samples collected from SB‐3 located at the western end of the UST exhibited 
naphthalene concentrations exceeding the Residential MSCCs, but not the 
Industrial/Commercial MSCCs. 
 Monitoring well MW‐1 was located, gauged, purged and sampled. 
 LNAPL was not identified at the site during this sampling event but was detected in 
September 2015. 
 Benzene and 1,2‐dibromoethane concentrations in groundwater from MW‐1 exceeded 
the GCLs. Numerous targeted compounds exceeded the 2L Standards. 

Based on the results of assessment and monitoring activities conducted at the site in association 
with this TA, WR recommends the following: 
 Abandon the 10,000‐gallon compartmentalized UST due to its proximity to the on‐site 
building and previous caving in of soils beneath the on‐site building during the removal of 
two 1.000‐gallon gasoline USTs. 
 Conduct an AFVR event on monitoring well MW‐1. 
 Install two additional monitoring wells to determine groundwater flow direction. 
 Consider replacing MW‐1 as it has a bent casing. 
 Conduct slug testing.

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

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.
