1.  []{#ExecSum .anchor}**Executive Summary**

This sampling plan was prepared by the Nevada Division of Environmental
Protection (NDEP) to support the environmental sampling component of the
Centers for Disease Control and Prevention's (CDC) National Center for
Environmental Health (NCEH) study entitled, "A Cross-Sectional Exposure
Assessment of Environmental Exposure Among Children with Acute
Lymphoblastic Leukemia/Acute Myelocytic Leukemia and A Reference
Population In Churchill County, Nevada." This document will be referred
to as the CDC/NCEH study protocol within this sample plan.

The CDC/NCEH study protocol was designed to assess exposure to a variety
of chemicals, radioactive elements, and infectious agents among children
diagnosed with leukemia (acute lymphocytic leukemia \[ALL\] and acute
myelocytic leukemia \[AML\]), and compare their exposure to that of
their immediate family members (parents and siblings only) and to
reference families. The reference families will consist of children
without cancer diagnoses, and their parents. Exposure will be assessed
by measuring for specific analytes within blood, urine, and indoor and
outdoor environmental samples, in conjunction with a questionnaire about
pertinent risk factors.

As described in the CDC/NCEH study protocol, the study was designed as a
cross-sectional exposure assessment of current exposures; it is very
difficult to collect reliable information about exposures that happened
in the past. Environmental samples will be collected from the current
household of each participating case and control family to help
interpret the results of the blood and urine tests. In addition to the
case-family's current home, environmental samples will be collected from
each house they previously occupied within Churchill County, Nevada
during the defined time period for this study. Environmental samples
will also be collected from the previous residences of 1 out of every 4
control children in each frequency strata. The control family whose
historic residences will be sampled will be randomly selected without
prejudice to number of residences or duration of residence. The CDC/NCEH
study protocol determined that environmental samples would consist of
indoor air, play yard soil, drinking water, and household dust from each
past and current residential location. NDEP will collect samples,
coordinate the laboratory analysis, and disseminate the results of the
indoor air, play yard soil, and household dust; the US Geological Survey
will be responsible for the collection and analysis of drinking water.

The CDC/NCEH will be provided the laboratory analysis of the
environmental measurements from participating family homes. If
environmental contamination or exposure is detected above enforceable
action levels, appropriate action by the Nevada Division of
Environmental Protection (NDEP) or other appropriate governmental entity
will be taken.

2.  []{#Background .anchor}**Background -- Study History**

The following background information was taken from the CDC/NCEH study
protocol document. In July 2000, Dr. Randall Todd, State Epidemiologist,
identified an increase in the incidence rate of ALL for Churchill
County, Nevada. According to the Nevada State Cancer Registry, the first
case of ALL diagnosed in Fallon, Nevada was in 1997, with 2 subsequent
cases in 1999, and 9 additional cases diagnosed by July 2000. In
September 2000, Dr. Todd began an investigation of the case families by
administering a questionnaire and collecting drinking water samples from
case-family homes. The questionnaire covered residential history prior
to conception, pregnancy history, water supply choices and use, chemical
use inside the home, occupational history of parents, sources for
radiation and electromagnetic (EMF) exposure, child activities, and
smoking in the home. The investigation did not reveal any obvious risk
factor or etiology. In total, 14 cases of childhood leukemia were
detected in Churchill County, Nevada between 1997-2001.

In February, 2001, Dr. Mary Guinan, State Health Officer for Nevada,
convened an Expert Panel to review the State of Nevada's investigation
and other literature about ALL among children. Following recommendations
from this Expert Panel, the State of Nevada formally requested
assistance from both CDC/NCEH and ATSDR on March 7, 2001 for further
evaluation of risk factors or etiologic exposures linked to this
childhood leukemia cluster in the Fallon area. ATSDR has been asked to
evaluate contaminant releases in Churchill County, Nevada and provide an
assessment of completed exposure pathways for the case families.
CDC/NCEH was asked to design and conduct a cross-sectional exposure
assessment of selective contaminants using environmental (household) and
biologic specimens for case families and a reference population.

**1.3** []{#SiteLocation .anchor}**Site Location and Description**

Environmental samples will be collected from residential properties of
both case and control families. Residences will be located both in
Fallon and throughout Churchill County. The control homes will be
selected by CDC/NCEH through a random-digit dialing protocol. There are
approximately 21 case homes, which include current and past Fallon
residences of the case families. There will be approximately 60 control
residential properties.

Situated in the Lahontan Valley at an elevation of 3,965 feet above mean
sea level, the City of Fallon is located 60 miles east of Reno, Nevada.
U.S. Highway 50 crosses the town in the east-west direction, and U.S.
Highway 95 passes through the town in the north-south direction. U.S.
Interstate 80 passes the area in a southwest-northeast direction 28
miles northwest of town and can also be reached traveling 32 miles north
of town. The incorporated area occupies approximately two square miles
within Sections 1, 25 and 36 of Township 19 North, Range 28 East, and
Sections 30, and 31 of Township 19 North, Range 29 East, Mount Diablo
Baseline and Meridian. The geographic coordinates are 39° 28' to 39° 29'
N latitude, 118° 27' 45\" to 118° 28' 45" W longitude.

**2.3** []{#Objectives .anchor}**Objectives and Data Use**

The objective of this sampling event is to support the Centers for
Disease Control and Prevention's study plan for "A Cross-Sectional
Exposure Assessment of Environmental Exposure Among Children with Acute
Lymphoblastic Leukemia/Acute Myelocytic Leukemia and a Reference
Population in Churchill County, Nevada." The CDC study design is a
cross-sectional exposure assessment of selective contaminants using
biological specimens and environmental field sample analysis for
case-family homes and a reference population. The cross-sectional
exposure assessment design will allow for the comparison of laboratory
testing results from case-children's blood and urine to their family
members' samples; and between case families and control families.
Environmental samples will be collected from the current and household
of each participating family (case and control) to assist the CDC's
interpretation of their results of the blood and urine tests. Past
households of case families and a portion of the control families will
also be sampled. The data collected in this study will also be used by
ATSDR to investigate and assess any completed exposure pathways in the
case families. Finally, the results of the environmental sampling will
be reviewed by the NDEP. If environmental contamination is detected
above enforceable action levels, appropriate action will be taken by the
NDEP.

**2.4** []{#Scope .anchor}**Scope of Work**

The NDEP designed this environmental sampling protocol for the
collection of surface soil, indoor air and home dust sampling for the
participating study homes. The NDEP will implement this environmental
sampling plan upon concurrence of the CDC/NCEH and appropriate agencies
that are part of this multi-agency investigation.

The CDC/NCEH study protocol estimated that environmental samples would
be collected from approximately 100 residences in Churchill County. This
figure includes current and past residences of cases (n=22), and current
residences of all control subjects (n=52), and past residences of 1 out
of every 4 control children enrolled in the study, assuming each control
family has 2 past residences in Churchill County (n=26).

The types of samples and analytical parameters were determined based on
goals and objectives of the CDC/NCEH study protocol and recommendations
of the expert panel that met in March and July 2001.

The locations and analytical parameters of the sampling will be
discussed in the following sections. Overall, NDEP will be collecting
the same set of samples from each participating case and control home.
These samples will include:

-   One outdoor soil sample

-   One indoor air sample

-   One indoor dust sample

-   One indoor radon kit

Field sampling will be consistent with EPA standard operating procedures
(SOPs), as appropriate, or other SOPs as determined by NDEP. Sample
handling and shipping will follow standard EPA Chain of Custody
protocols. All SOPs may be found as attachments to this document. If any
significant deviations from the SOPs occur during field implementation,
the sampling team will be responsible for documenting such deviations.

Laboratory analysis provided by EPA Region 9 will follow the Regional
Laboratory's Quality Assurance and Quality Control (QA/QC) practices
followed for EPA Superfund Sites. Some samples analyzed through the EPA
Regional laboratory will be sent to EPA Contract Laboratory Program
(CLP) laboratories for analysis. These laboratories will also follow
their EPA contract specified QA/QC procedures. The commercial
laboratories contracted by NDEP will provide the NDEP with information
regarding their use of performance evaluation samples, previous
laboratory audits, and ethical conduct. In addition, specific
information regarding the laboratory\'s performance with the particular
methods to be used for the samples will also be provided. This and other
information will be reviewed by the NDEP Project Manager and deemed
satisfactory before the laboratory is selected and a contract
negotiated.

**3.0** []{#Sampling .anchor}**SAMPLING PROCEDURE**

**3.1** []{#SampleCollection .anchor}**Sample Collection**

All sampling activities will be performed by the NDEP sampling teams.
Each team will consist of a team leader and two to three samplers. A
NDEP field coordinator will be stationed in Fallon and will coordinate
sampling schedules with the team leader and the residents. The team
leader will be responsible for communication with the residents of each
home. Each sample team will be responsible for the proper field
documentation and field collection of environmental samples. NDEP sample
teams will be familiar with the standard operating procedures (SOPs) for
this study and SOPs will be followed whenever possible.

Every effort will be made by the NDEP to ensure that the sample teams
will not know if a residential property is from the case or control
group. Samples will be identified by a house number assigned by the
CDC/NCEH and given to the NDEP field coordinator. The house number and
address will be given to the team leader. All samples and chain of
custody records will only utilize the house number. Sample number and
type will be denoted by the following code:

House Number \-- Matrix \-- Sequence:

House Number:

Assigned by CDC/NCEH. Numbers will run from 001 through 100.

Matrix:

Surface Soil = SS

Home Dust = HD

Wipe Sample = WS

Indoor Air = IA

Radon Kit = RK

Equipment Blank = EB

Sequence:

Samples will be numbered according to the number of samples collected at
each residence. This last number is provided in case additional samples
are needed at a sample location. For example, if two dust samples are
required at House #17, the following sample numbers would be used:

> 017-HD-01 and 017-HD-02

This would denote that House 17 had two dust samples; HD-01 and HD-02.

[Table 1](#Table1) provides a summary of sample type and general
location for the sample.

**3.2** []{#SamplingMatrices .anchor}**Sampling Matrices**

The following sections describe the sample collection procedures for the
various matrices that will be collected during the sampling event.

3.2.1 []{#SoilSamples .anchor} Soil Samples

One soil sample will be collected from a children's play area at each
study residence. The specific area will be determined by the team leader
after consulting with the residents of each home. The sample will
consist of a three-part composite of the surface soil of the designated
play area. Samples will preferably come from dirt play areas.

All surface soil composite samples will be collected at a depth of 0 to
3 inches using disposable scoops and aluminum pans. The sampler will don
a disposable Tyvek suit and booties and use clean powder-free latex or
nitrile gloves at each sampling location to minimize the chance of
cross-contamination. The samples will be homogenized in a dedicated
aluminum tray. Homogenization will be performed by removing all stones
and extraneous matter, thoroughly mixing the aliquots, and dividing the
soil into four roughly equal aliquots. This procedure will be repeated
three times.

If all of the play areas at a study residence are grass covered, three
(3) small areas of grass will be removed and the first 0-3 inches of
soil below the grass cover will be collected from the area. The grass
will be removed with a small disposable or steel garden trowel. Care
will be taken to replace the grass and clean potting soil will be added
below the grass to restore the sample area. All soil sampling activities
will be conducted according to the Surface Soil Sampling Standard
Operating Procedure (SOP) developed for this sampling event; this SOP
may be found as [Attachment A](#AttachmentA).

2.  []{#AirSamples .anchor}Air Samples

One air sample will be collected from a frequently used room of each
study home, such as the living room or other room frequently used by the
children of the family. The sample will be collected as a "grab" or
instant sample by using a Summa canister. The exact location will be
determined after consulting with the residents of each home. The
canister will be placed at a height of approximately three feet off the
ground. This height was selected to approximate a child's breathing
zone.

Air samples will be collected in accordance with the Summa Canister Air
Sampling SOP, developed for this sampling event; this SOP may be found
as [Attachment B](#AttachmentB). The samples will be sent to an approved
laboratory for analysis of volatile organic compound parameters. The
canisters and all sampling equipment will be pre-cleaned and provided by
the EPA Regional laboratory. The Summa will be sent to the selected
laboratory for analysis and then returned to the EPA Regional laboratory
to be cleaned for reuse.

3.  []{#DustSamples .anchor}Dust Samples

Vacuum dust samples will be collected from the living areas of each
study home. This will include the living room, dining room, bedrooms,
hallways and kitchen. Samples will not be collected from generally
inaccessible areas such as behind the refrigerator, storage closet/attic
or crawl spaces. The areas sampled will be measured and recorded in
order to perform quantitative calculations.

Approximately 70 grams of sample will be needed to perform the full list
of analytical parameters described in the CDC/NCEH Cross Sectional
Exposure Study. The EPA Regional laboratory will be using approximately
5-10 grams for metals analysis and approximately 30 grams for
organo-chlorine pesticide and PCB analysis. The remaining sample volume
will be sent by the EPA Regional Laboratory to the Nevada Department of
Agriculture (NDOA) to be analyzed for organo-phosphate, carbamate, and
pyrethroid pesticides.

Samples will be collected with a Nilfisk Vacuum and collection
procedures will follow the Nilfisk Home Dust Sampling SOP, developed for
this sampling event; this SOP may be found as [Attachment
C](#attachment-c).

A separate dust sample will be collected as a dry-wipe sample and will
be laboratory analyzed for gamma spectrometry, and Uranium 234, 235, and
238. This sample will be collected from a television screen in a family
room or a computer monitor, if the television screen is inappropriate
for sample collection. The wipe sample will be sent directly to a
contract laboratory arranged through the Nevada State Health Department.
The field sampling will be conducted according to the Dry-wipe Sampling
SOP, developed for this sampling event; this SOP may be found as
[Attachment D](#AttachmentD).

4.  []{#RadonKits .anchor}Radon Kits

Radon test kits will be placed in an appropriate location by the sample
team leader in accordance with the Radon Canister SOP developed for this
sampling event; this SOP may be found as [Attachment E](#AttachmentE).

The homeowner will be contacted prior to placement of the radon test kit
and instructed to keep the house closed at least 12 hours prior to
placement. It is necessary to keep all external doors and windows closed
for at least 12 hours prior and during the entire test period. Normal
coming and going is acceptable, however external doors should not be
left open for periods of more that a few minutes. Internal/external air
exchange systems other than the furnace, such as high volume attic and
window fans, should not be operated for at least 12 hours prior to and
during the measurement period. Operation of closed circulation systems
should not affect the test. Swamp coolers must not be utilized.

At the end of the test period, the testing team will collect the test
kits, prepare the appropriate forms and send the test kit to the
laboratory for analysis. The homeowner will receive the test results
within two weeks. The Nevada State Health Division will also receive the
test results on a monthly report. The homeowner may obtain
interpretation of the test results from the Nevada State Health Division
at (775) 687-5394 extension 275.

2.  **Documentation**

A sampling team member will document sample conditions; estimate ambient
air temperature (indoor and outdoor), cloud cover, and other relevant
observations of the sample property and adjacent properties.
Documentation will be conducted by using the Combined Field Data Sheets,
developed for this sampling event. These field data sheets can be found
at the end of every SOP.

**3.4** []{#Decontamination .anchor}**Decontamination**

Personnel field gear and the majority of field sampling equipment
scheduled to be used at this site will be disposable and will be
double-bagged and disposed of as dry industrial waste. Any
non-disposable sampling equipment, such as stainless-steel trowels, will
be decontaminated at the Fallon field office and will utilize
appropriate procedures, such as washing with a solution of Alconox
(phosphate detergent) and distilled water. Decontamination of the
Nilfisk dust sample equipment will follow procedures outlined in the
Vacuum Sampling SOP. All other field decontamination will follow the
Decontamination SOP developed for this sampling event; this SOP may be
found as [Attachment F](#attachment-f).

**4.0** []{#AnalyticalParameters .anchor}**ANALYTICAL PARAMETERS**

[Table 2](#Table2) provides a summary of the sampling matrices,
analytical parameters, analytical methods, sample containers, and
designated laboratory for this sampling event. Detection levels will be
the best achievable given the sample volumes actually collected for each

**5.0** []{#QA_QC .anchor}**QA/QC PROCEDURES**

1.  []{#QA_QC_Responsibility .anchor}**Responsibility**

The NDEP Environmental Sample Coordinator will be responsible for
ensuring that sample quality and integrity are maintained. The Sample
Coordinator will also ensure that sample labeling and documentation are
performed in accordance with the labeling SOP developed for this
sampling event; this SOP may be found as [Attachment G](#AttachmentG).

Air carriers that transport hazardous materials, in particular Federal
Express, require compliance with the current International Air Transport
Association (IATA) Regulations, which applies to the shipment and
transport of hazardous materials by air carrier. This study will be
utilizing air carriers to transport environmental samples (not hazardous
waste samples), and will be shipping small quantities of water samples
preserved with nitric acid. The water samples will be generated during
field QA/QC procedures. NDEP will follow IATA regulations to ensure
compliance.

**5.2** []{#FieldQC .anchor} **Field QC**

Field QC will consist of collecting and analyzing rinsate blanks and
field duplicates.

The duplicate samples will be collected for the soil and air samples at
a rate of one per 20 samples. Duplicates for the air samples will be
collected by filling the containers simultaneously. Duplicates for the
soil will be collected by splitting the sample volume into two distinct
samples. Each sample from a duplicate set will have a unique sample
number; the duplicates will be sent \"blind\" to the lab. Because of
limited availability of amounts (mass) of dust, duplicate dust samples
will be collected as appropriate, based on mass collected in the field.

Rinsate blanks will be collected to test for contamination that could
possibly be introduced by the reusable sample equipment used for this
study. They will be collected on the vacuum sampling equipment that will
be decontaminated for reuse. The blanks will be collected at the rate of
one per 20 samples and be analyzed for all parameters. The blanks will
be collected according to the Field Rinsate Blank SOP, prepared for this
sampling event; this SOP may be found as [Attachment H](#attachment-h).

Field QC will also include completing Chain of Custody documentation.

**5.3** []{#LaboratoryQC .anchor}**Laboratory QC**

A field sample will be designated as a \"lab QC sample\" at a frequency
of 1 per 20 samples and be analyzed for all parameters. The lab QC
sample is the sample the laboratory will use for its internal quality
control analyses. The lab QC sample will be a sample suspected of being
contaminated and which is representative of other contaminated samples.
The lab QC sample will consist of a double volume of sample. The sample
containers and paperwork will be clearly labeled \"Lab QC Sample.\"

Laboratory QC samples will be collected from the soil and dust samples
as field conditions permit:

The EPA Regional Laboratory QC will comply with all Regional Laboratory
SOPs. Contract Laboratory Program (CLP) analysis will consist of all QC
stated in the CLP Statement of Work (SOW) and includes all forms and
deliverables required in the SOW. Laboratory QC for commercial labs will
be determined by the NDEP contract with the laboratory.

The NDOA and contract laboratories will follow their standard QC
procedures.

4.  []{#FieldVariances .anchor}**Field Variances**

As conditions in the field may vary from that planned or conceived, it
may become necessary to implement minor modifications to sampling as
presented in this plan. When modifications are needed, the team leader
will be notified, and when appropriate, other members of the project
team may be consulted. In all cases, documentation of field changes will
be conducted by the sample team.

**5.5** []{#DataValidation .anchor}**Data Validation**

Data validation for the samples analyzed through EPA Regional laboratory
and CLP laboratory will be performed by EPA Region 9 Regional
Laboratory's Quality Assurance Staff in accordance with CLP National
Functional Guidelines for Data Review for all soil and dust samples
analyzed through EPA. Data validation for analysis through commercial
labs will be determined by the NDEP contract with the laboratory.

**6.0** []{#Reporting .anchor}**REPORTING**

Information gathered from this study will be received by the NDEP. NDEP
will compile the analytical results and field reports according to study
number designations. The completed sampling information will be
forwarded to the CDC/NCEH. **[A summary of the results will also be
prepared so that a report from NDEP can be forwarded to the property
owner of each study home.]{.underline}** The results of the
environmental sampling will also be reviewed by NDEP. If environmental
contamination is detected above enforceable action levels, appropriate
action by will be taken by the NDEP.

1.0 SCOPE AND APPLICATION

The purpose of this Standard Operating Procedure (SOP) is to provide the
sampling teams with a step-by-step guide for collecting composite
surface soil samples using hand trowels. Samples will be collected in
outdoor areas most frequently used by children.

2.0 EQUIPMENT/MATERIAL REQUIRED

Below is a list of the materials needed for surface soil sampling
events. Both disposable and reusable sampling equipment are required.

-   Personal protective equipment (as specified in the Health and Safety
    Plan)

-   Sampling Plan (SP)

-   Property location Map/Fallon Street Map

-   8-oz glass sample containers w/lids

-   Sample log sheets

-   Sample labels/tags

-   Coolers

-   Ice

-   Aluminum mixing tray

-   1-gallon Ziploc® bags

-   Paper towels

-   Ballpoint pen

-   Permanent marker

-   Plastic (disposable) trowels

-   Steel trowel

-   Plastic trash bags

-   Potting soil

3.0 SAMPLING PROCEDURES

> 3.1 Perform a general site reconnaissance to verify actual site
> conditions consistent with the HASP. Make entries onto the field data
> sheet as called for on the sheet.
>
> 3.2 Locate surface soil sampling area: Identify area of the property
> most used by children, for example; play areas, or walk ways. Describe
> the area on the Field Data Sheet and estimate the distance and
> direction from a permanent marker, (20 feet NW of the NE corner of the
> house, utility pole, etc.).
>
> 3.3 Select a sample area of approximately 25 square feet for the
> collection of a three-part composite sample. Sample parts will be
> collected from three locations within the sample area. If the
> child-use area is less than 25 square feet, see Grab Sample
> instructions in Step 3.10 below.
>
> 3.4 Collect Samples: Put on clean, disposable latex surgical gloves
> (equivalent) prior to collecting soil samples.
>
> With the plastic and/or steel trowel, collect 6 heaping trowel-volumes
> from each of the three-part sample locations (18 total volumes) from
> 0-3 inches below ground surface and put the soil into an aluminum
> mixing pan. Sample collection will focus on soil particles, not other
> materials intermixed in the soil matrix. Using hands covered with
> surgical gloves, remove plant material, roots, pebbles
> greater-than-pea-size (1/4" diameter), rocks, concrete etc. from the
> aluminum mixing pan and place them in one of the sample holes.
>
> If the sample area is covered by grass turf or other non-soil
> material, cut away or remove approximately 1 square foot of the
> non-soil material with a steel trowel and collect soil from 0-3 inches
> below the cut-away material with the plastic trowel. Replace the
> removed soil with potting soil, and place non-soil material on top.
> Tamp it down with your foot and water with home resident's approval
> and water source.
>
> 3.5 Thoroughly mix the soil volume in the aluminum pan with the
> plastic trowel or glove-covered hands. Note the qualities (color,
> texture, etc.) of the homogenized sample on the sample log sheet as
> called for on the sheet.

3.6 With the plastic trowel, place the mixed soil into sample containers
as follows.

-   1 full 8-oz glass jar (Metals analyses)

-   1 full 8-oz glass jar (o-chlorine pesticides analyses)

-   1 full 8-oz glass jar (o-phosphate pesticides analyses)

-   1 full 8-oz glass jar (Aroclor PCBs and SVOCs analyses)

-   1 full 8-oz glass jar (Archive)

-   16 oz (approximate) of soil in a double Ziploc® bag (rad analyses)

> Place remaining soil into one or more of the sample holes. Top off
> with potting soil.
>
> 3.7 Label each sample container according to the labeling conventions
> outlined in the SP. Sample labels will be preprinted. Fill out
> information called for on the label with a permanent marker
> *(ballpoint pen ink bleeds when wet)*.
>
> > 3.8 Place each glass sample container into a separate Ziploc® bag
> > and put on ice in a cooler. Place the double Ziploc® bag sample
> > container (Rads sample) in cooler [without]{.underline} ice.

3.9. Place disposable plastic trowel, aluminum mixing pan and other
trash into a plastic bag for disposal. If a steel trowel is used, place
it in a bag for transport back to the field office where it will be
decontaminated.

3.10 If the sampling location is less-than 25 square feet, collect one
grab sample from one sample hole from 0-3 inches below ground surface.
Follow Steps 3.4 through 3.9.

3.11 Keep samples, clean equipment, and trash separate to prevent
cross-contamination. Transport these items to the field vehicle.

4.  QUALITY ASSURANCE/QUALITY CONTROL

To prevent contamination of soil samples from compounds introduced to
the site by the sampling teams, personal protection equipment must be
worn and used as specified in the Health and Safety Plan (HASP). Health
and Safety procedures outlined in the HASP must be followed.

Duplicate samples shall be collected at a ratio of 1 for every 10-sample
properties (1:10) for quality control purposes (Blind to Labs).

4.1 Collect 12 heaping scoops from each sample hole to be able to fill
duplicate sample containers for each analysis (i.e.: 2 jars for metals,
2 jars for o-chlorine pesticides, etc.).

4.2 Follow Steps 3.4 through 3.6 above.

4.3 Label the original and duplicate sample containers according to the
labeling conventions outlined in the SAAP.

4.4 Follow steps 3.7 through 3.11 above.

Lab matrix blanks shall be collected at a ratio of 1 for every 20-sample
properties (1:20) for quality control purposes (Not blind to Lab).

4.5 Collect extra sample volumes from each sample hole to be able to
fill 5 extra (lab matrix) sample containers.

4.6 Label these samples the same as the original sample and note on the
label "lab matrix QC".

5.  HEALTH AND SAFETY

Health and Safety procedures as described and defined in the NDEP Health
and Safety Plan (HASP) must be observed and implemented prior to dust
sample collection. Chemical exposures are not anticipated, and physical
or mechanical hazards are only those that would be found in any typical
household environment.

1.  SCOPE AND APPLICATION

> The purpose of this standard operating procedure (SOP) is to describe
> a procedure for sampling of volatile organic compounds (VOCs) in
> ambient air. The method is based on samples collected as whole air
> samples in Summa passivated stainless steel canisters. The VOCs are
> subsequently separated by gas chromatography (GC) and measured by
> mass-selective detector or multidetector techniques. This method
> presents procedures for sampling into canisters at final pressures
> below atmospheric pressure (referred to as sub-atmospheric pressure
> sampling). The Fallon Cross-sectional Exposure Assessment (CEA) study
> will include sampling for VOCs from "control and case" sets of homes
> to develop a statistical database. The canisters are sent to a
> certified testing lab in a timely fashion to insure quality of sample.
> The results will be returned to NDEP for consolidation and
> distribution to appropriate agencies or homeowners.
>
> This method is applicable to specific VOCs that have been tested and
> determined to be stable when stored in sub-atmospheric pressure
> canisters. The organic compounds that have been successfully collected
> in pressurized canisters by this method are listed in the Volatile
> Organic Compound Data Sheet at the end of this SOP. These compounds
> have been measured at the parts per billion by volume (PPBV) level.
> Chemical compounds to be analyzed are listed in [Table 3](#Table3).
>
> These are standard (i.e., typically applicable) operating procedures
> which may be varied or changed as required, dependent on site
> conditions, equipment limitations or limitations imposed by the
> procedure or other site limitations. In all instances, the sampling
> team should document the procedures employed.
>
> Mention of trade names or commercial products does not constitute NDEP
> endorsement or recommendation of use.

2.  METHOD SUMMARY

> Sub-atmospheric pressure sampling uses an initially evacuated
> canister. The canister has a hand valve and fixed orifice to regulate
> flow. Sub-atmospheric pressure sampling is performed without a
> micrometering valve for taking grab samples. With this configuration,
> a grab sample of ambient air is drawn into a pre-evacuated Summa
> passivated canister. The canister is placed in the approximate
> breathing height of the child. The hand valve is opened a quarter turn
> until the sound changes as it nears atmospheric pressure, and the hand
> valve is then closed. Normal documentation, custody and sealing of the
> sample are completed and the package is readied for shipping.
>
> 3.0 SAMPLE PRESERVATION, CONTAINERS HANDLING, AND STORAGE
>
> After the air sample is collected, the canister valve is closed, cap
> is installed, an identification tag is attached to the canister, and
> the canister is transported to a laboratory for analysis. Upon receipt
> at the laboratory, the canister tag data is recorded. Sample holding
> times and expiration are to be determined prior to initiating field
> activities.
>
> Care must be taken not to exceed 40 psi in the canister (do not heat
> canister above 140 ^o^F). Canisters should not be dented or punctured.
> They should be stored in a cool dry place and always be placed in
> their cardboard shipping boxes or similar protective carrier during
> transport and storage.
>
> 4.0 INTERFERENCES AND POTENTIAL PROBLEMS
>
> Contamination may occur in the sampling system if canisters are not
> properly cleaned before use. Additionally, all sampling equipment
> should be thoroughly cleaned. Instructions for cleaning the Summa
> canisters are described in ERT/REAC SOP \# 1703, Summa Canister
> Cleaning Procedures. During this study pre-certified and clean
> canisters are being supplied. No cleaning of the exterior is required.
>
> 5.0 EQUIPMENT/MATERIALS REQUIRED

The following equipment/apparatus (see [Figure 1](#Figure1)) is
required:

-   Sub-atmospheric Pressure Sampling Equipment

-   VOC canister sampler -- whole air sampler capable of filling an
    initially evacuated canister by action of the hand valve from vacuum
    to near atmospheric pressure.

6.0 PROCEDURE

1.  Sub-atmospheric Pressure Sampling using a Hand Valve and SUMMA
    (vacuum) Canister.

2.  Prior to sampling collection, the appropriate information is
    completed on the Canister Sampling Field Data Sheet found at the end
    of this SOP and brass cap is removed\
    with ^9^/~16~-inch end wrench.

3.  Place canister at the "breathing height" of the child (approximately
    the height of an average knee) in a room where the child spends the
    most of the time.

4.  A canister, which is evacuated to at least 26 inches Hg hand valve,
    is opened to the atmosphere containing the air to be sampled.

5.  The pressure differential causes the sample to flow into the
    canister.

6.  This technique is used to collect grab samples (duration of 15 to 30
    seconds). The sampling duration depends on the degree to which the
    flow is restricted.

7.  A fixed-orifice flow restrictor will have a decrease in the flow
    rate as the vacuum canister approaches atmospheric (which is
    indicated by a change in pitch or sound level). Shut off hand valve
    immediately to avoid canister becoming neutral with atmosphere. (It
    should remain in a slight vacuum.) If the canister is allowed to
    become neutral, the test is void. Repeat test with new canister.

8.  Upon sample completion at the location, the appropriate information
    is recorded on the Canister Sampling Field Data Sheet and labels
    (Note the final vacuum reading on canister: approximately 2 to 10
    inches of mercury (Hg) by gauge on tank or separate gauge as
    available on each canister. Separate gauge will need to be attached
    and removed. Zero gauge before reading).

9.  Cap the SUMMA Canister with the cap and tighten with wrench slightly
    to seal vacuum.

10. Place canister into a cardboard box labeled for shipping with the
    Field Data Sheet information and labels in the plastic luggage tag
    type of holder.

7.  QUALITY ASSURANCE/QUALITY CONTROL

The following general quality assurance procedures apply:

1.  All data must be documented on standard chain of custody records,
    field data sheets, or site logbooks.

2.  All instrumentation must be operated in accordance with operating
    instructions as supplied by the manufacturer, unless otherwise
    specified in the work plan. Equipment checkout and calibration
    activities must occur prior to sampling/operation, and they must be
    documented.

3.  Duplicate samples will be taken as 1 in 10-samples.

4.  Blank samples or "zero air," (sample not taken) will be returned as
    1 in 20-samples.

8.0 HEALTH AND SAFETY

Health and Safety procedures as described and defined in the NDEP Health
and Safety Plan (HASP) must be observed and implemented prior to dust
sample collection. Chemical exposures are not anticipated, and physical
or mechanical hazards are only those that would be found in any typical
household environment.

1.0 SCOPE AND APPLICATION

The collection of indoor dust samples for multi-purpose comparison
requires systematic and regimented collection and handling protocol. It
is the consistent routine practiced at each individual collection
location that allows a direct and representative interpretation of data.

This sampling method defines the fundamental techniques necessary to
obtain representative and defensible indoor dust samples to support an
environmental project or study effort. Recognize that there may be
site-specific circumstances that necessitate deviation from the standard
protocol described in this sample collection procedure, and in such
case, documentation and record-keeping diligence is of utmost importance
to justify any alternative practice employed.

2.0 METHOD SUMMARY

Sample collection focuses on maximization of both sample mass and
careful documentation of area in which sample mass is collected. The
Nilfisk GS-80 high-volume sampler, equipped with a high-efficiency
particulate air (HEPA) filter, will be used to collect sample mass from
pre-measured areas throughout study homes. Recoverable sample media
includes soil and particulate matter having cross-sectional dimensions
of approximately 5 micrometers (µm) and larger, typically embedded in
carpets or deposited on hard-surface areas.

Sample mass will be collected in a vacuum bag protected and secured with
a secondary poly liner. The poly liner allows the vacuum bag to be used,
removed, and shipped with minimal exposure to cross-contamination
locations. The initial sample is a combination of the dust collected,
the vacuum bag, and the liner until the sample can be properly processed
in a controlled, laboratory environment. A diagram of the Nilfisk GS-80
vacuum is shown as [Figure 2](#Figure2).

Primary sample areas will target living areas in which children are most
likely to play or spend proportionately longer amounts of time, i.e. in
front of the television, in the middle of the family-room floor, and the
bedroom floor. In addition, entryways or areas in front

of doorways will also be considered primary sample target locations
because of the propensity to track dirt and dust inside the home from
outside areas.

It is crucial to the success of this sampling effort to make every
attempt to properly obtain as much sample mass as may be available in
any particular household. Because the target analyte list (TAL) is
relatively extensive, sample mass is the overall limiting factor
affecting the comparability of data obtained. Consequently, in instances
where study homes are relatively small or when extracted dust mass from
primary target living areas is not likely to be sufficient to support
the TAL, secondary target areas including hallways and/or additional
bedrooms may be systematically sampled to increase the total mass of the
dust sample acquired.

In addition to the dust sample collected using the Nilfisk High-Volume
Surface Sampler, relinquished household vacuum bags will be collected as
a precautionary measure. In the event that analytical results pertaining
to the collected dust sample indicate discrepancies or inconsistencies,
additional dust mass will then be available for supplemental
examination. The household vacuum bags will be collected only if they
have been used exclusively in the home.

Collected samples will be transported to the Nevada Division of
Environmental Protection (NDEP) field office for shipment to the
Environmental Protection Agency (EPA) Laboratory in Richmond,
California. If additional TAL analyses are required to be performed at
alternate laboratories, sample mass will be divided at the EPA
Laboratory and shipped under supplemental chain-of-custody procedures.

3.0 EQUIPMENT/MATERIALS REQUIRED

The following materials will be required to conduct the dust samples.
Both disposable and reusable sampling equipment is required.

-   Nilfisk Model GS-80 High-Volume Surface Sampler (vacuum cleaner)

-   Nilfisk vacuum bags

-   Poly liners for vacuum bags

-   Sealed storage container (Ziploc® bags)

-   Razor Blade or knife

-   One (1) square meter (m^2^) folding rulers or similar measuring
    device

-   Masking tape

-   Analytical balance (at field office)

-   Distilled water

-   Methanol

-   Kimwipes™ or equivalent laboratory tissue/towel

-   Plastic bags

4.  SAMPLE PROCEDURES

    1.  Review field data sheets, and documentation materials to confirm
        adequate and appropriate field supplies, sample locations, and
        preliminary measurement requirements.

    2.  Upon arrival at the sampling location, document field conditions
        per the field log forms and record all requested general
        information. Don appropriate field sampling apparel including
        Tyvek™ pants, Tyvek™ over-shirt, and booties. Make sure to don
        booties at the threshold to the residence prior to entering.
        Take extra surgical gloves in the house for subsequent use.

    3.  Survey primary and secondary target sample areas and sketch the
        area to be sampled. At a minimum, primary target areas should
        include the main area in the living room and/or family room, the
        area immediately in front of the television (if possible), the
        main area in the child's or children's bedroom(s), and the entry
        way or area in front of the primary entrance to the home.
        Secondary areas may include hallways or additional bedrooms,
        (not bathrooms) as necessary or appropriate, depending on the
        mass of sample that is expected to be available at the
        residence. Record additional information required on the field
        log forms, as appropriate.

    4.  Use the folding ruler or template to define 1-square meter
        (m^2^) areas to be vacuumed. Masking tape can be used, if
        needed, to mark off the perimeter of the 1-square meter areas
        designated for sample collection. Do not touch the designated
        sample areas with ungloved hands. Using masking tape with
        surgical gloves is not practical; therefore, extreme caution
        must be observed while taping to protect the unaltered integrity
        of the sample area. If square meter areas are immediately
        adjacent, the entire area may be taped in a single unit as long
        as the exact area is measured and logged. Allow narrow walking
        paths between the targeted sample areas for maneuverability.
        Make every attempt to remain outside the delineated areas while
        preparing the sample areas and conducting the sampling. Do
        **not** allow the Nilfisk vacuum canister to roll into the
        segregated sample areas. If used, put the used masking tape in a
        Ziploc® bag when finished taping delineated sample areas.

    5.  Record the area designed for sampling in each room, as well as
        the total area designated for sampling within the entire
        residence.

    6.  Assemble the Nilfisk GS-80:

(Done at office before leaving by staff)

1.  Unlatch the two lower, side canister wing nuts configured in the
    front and back of the unit (below the Nilfisk logo and above the
    hose connection).

2.  Cut a 3-inch cross in one side of the poly liner approximately ½-way
    between the top and bottom of the liner.

3.  Slip the cut aperture over the vacuum intake port and fit the body
    of the liner into the canister so that the edges of the liner fold
    out over the lip of the canister bottom. The top of the liner bag
    will be seen from the outside of the canister and will be secured
    when the top of the canister is reattached.

4.  Set the vacuum bag on top of the poly liner (note the bag indicates
    which side should face up) and expand the bag manually to allow
    unimpeded flow through the bag.

5.  Secure the opening of the vacuum bag to the aperture where the hose
    fits onto the canister.

6.  Once the poly liner and the bag are secured, reseat the top of the
    canister over the housing compartment, engage the wing nuts, and
    fold the wings for a secure fit. Make sure not to pinch or tear the
    edges of the exposed poly liner. Tape down wing nuts with packing
    tape to prevent opening.

> (Done in the field)

7.  Insert the hose into the intake port, matching the notches in the
    male connection to the notches in the female port, press and turn to
    engage and lock the connection. The hose should be snug, without
    lateral give, and the rubber gasket should be square to the base of
    the intake port.

8.  Slip the appropriate vacuum head for the sample surface onto the
    loose end of the vacuum hose. This connection is a tapered-slip
    connection, therefore, use conservative pressure to secure the
    vacuum head to the hose. Should the vacuum head dislodge, slightly
    twist the hose into the vacuum head while applying pressure to
    create additional friction.

9.  Adjust the vacuum head to extend brush down on hard surfaces or up
    for use on carpet surfaces.

```{=html}
<!-- -->
```
7.  Working from the sample area at nearest side of each room toward the
    farthest, begin sample collection at one corner of a delineated
    sample area. Move the vacuum head slowly and deliberately in strips
    the width of the vacuum head along a lateral axis of the square
    area. Pass the vacuum head back and forth four times over each
    lateral strip, for a total of eight strokes, and on the last pass,
    angle the vacuum head to the right or left (depending on the initial
    corner selected) to begin the next strip, which will be the width of
    the vacuum head, immediately adjacent to the completed strip. Again,
    pass the vacuum head back and forth for four complete cycles over
    the second lateral strip and then angle the vacuum head to begin the
    third adjacent strip. Continue this process until the entire
    designated unit has been vacuumed with four "double" passes of the
    vacuum head.

8.  Visually inspect the sampled area to assess sample collection
    efficiency. If visible dust and dirt remain, or if dust or dirt can
    be dislodged by agitating carpet fibers with fingertips, then
    document the observations and rationale used for continuing the
    sample collection protocol and repeat step 4.7. If not, prepare to
    sample the remaining delineated sample areas.

9.  Move to the next delineated area designated for sample collection
    and repeat steps 4.7 and 4.8 until all of the delineated sample
    areas have been carefully sampled. Turn off the vacuum when sampling
    is complete.

10. After all delineated sample areas have been vacuumed according to
    steps 4.8 and 4.9:

    1.  Hold the vacuum head in the air away from any objects or
        surfaces and turn on the vacuum;

    2.  Tap the nozzle against your hand to dislodge any residual dust
        remaining in the nozzle or the hose for collection in the
        canister;

    3.  Turn off the vacuum cleaner and allow it to sit undisturbed for
        at least 30 seconds;

    4.  Unsnap the two lower wing-nuts and remove the upper body of the
        canister from the collection chamber;

    5.  Carefully pull the poly liner away from the outside of the
        canister and surround the inner vacuum bag;

    6.  Carefully pull the vacuum bag away from the intake port and fold
        the aperture to secure the dust contents to the degree possible
        without the use of adhesives. Close the poly liner around the
        vacuum bag using caution to secure the package;

    7.  Transfer the poly liner/vacuum bag package into a Ziploc®
        plastic bag;

    8.  Label the exterior of the plastic bag with the designated sample
        number as described in Section 3.0 of the Sampling Plan; and

    9.  *(By office staff*): Log the sample numbers on the proper
        Chain-of-Custody form(s). Complete the field sample form and
        store the secured sample in a moderately chilled cooler during
        transportation and shipment to the designated laboratory.
        Custody-seal the cooler prior to shipment.

4.11 Unplug and prepare the Nilfisk GS-80 for demobilization. Collect
all auxiliary equipment and gear and remove them from the residence.

4.12 Request from the residence, if available, contents of the
household's vacuum bag for back-up samples.

5.  CONTINGENCY SAMPLE MEASURES

    1.  If there is no carpet, measure and tape, if needed, hard-floor
        areas using the same protocol as that described for carpeting,
        but work with the vacuum head brushes down. It will be
        imperative to maximize sample area and avoid touching delineated
        sample areas with anything except the vacuum head. Delineated
        sampling units in a configuration that affords access and
        maneuverability and follow the standard operating procedures.

    2.  Determine if the household vacuum has been used exclusively in
        the home and if so, politely request the study participant to
        relinquish the household vacuum bag. If the study participant
        consents, collect the vacuum bag while wearing gloves to avoid
        contaminating the sample, and secure the vacuum bag in a plastic
        bag. Double bagging may be necessary. Label the household vacuum
        bag sample in accordance with the procedures defined in Section
        3.0 of the Sampling Plan.

5.3 Maximizing sample mass is critical to the success and comparability
of this environmental sampling event. Consequently, if subject residence
conditions are atypical and cannot be accommodated by standard operating
procedure, alternative sampling procedures may be implemented as long as
conditions and rationale used to justify such deviations are documented
and recorded in detail on field sample forms. There is no reasonable way
to anticipate every possible conditional anomaly, therefore, field teams
must use sound judgment and good, defensible scientific practice if
implementing sampling procedures alternative to those described.

[6.0]{.smallcaps} NILFISK SYSTEM DECONTAMINATION GS-80 S

At the end of each sampling event, decontaminate the Nilfisk GS-80 and
all auxiliary equipment in a well-ventilated area in accordance with the
following procedure:

1.  Assemble one of the sampling trains to be used as the
    decontamination unit for decontaminating all of the used vacuum
    heads, hoses, and wands. Insert a clean poly liner and vacuum bag to
    perform the bulk decontamination procedure.

2.  Put on clean surgical gloves and attach a hose and vacuum head
    assembly to the vacuum canister. Turn on the vacuum and use a bottle
    brush to remove any accumulated dust. Tap your hand on the vacuum
    head to remove any visible dirt that accumulates on the brush. When
    the vacuum head is visibly clean, remove the vacuum head and spray
    with reagent grade methanol. Allow the vacuum head to air dry on a
    clean surface.

3.  Use the bottle brush again to clean the wand and hose to dislodge
    residual dirt and dust. Again, tap your hand on the wand intake
    while cleaning with the bottle brush to increase the vacuum in the
    hose.

> 6.4 Repeat steps 6.2 and 6.3 for each vacuum head, wand, and hose
> assembly requiring decontamination.

5.  When all ancillary Nilfisk GS-80 equipment has been decontaminated,
    remove the dirty dust bag and poly liner and wipe the inside of the
    collection chamber with distilled water. Wipe the inside of all
    other collection chambers with distilled water as well. Spray all
    Nilfisk collection chambers with reagent grade methanol and allow to
    air-dry. If decontaminating equipment between residences, wipe the
    inside of the collection chambers between uses.

6.  Wipe the one (1) square meter (m ^2^) folding ruler, or equivalent,
    with distilled water and then spray with methanol. Allow to air-dry
    on a clean surface.

7.  Label decontaminated equipment indicating the date of last
    decontamination and the initials of the person performing the
    decontamination procedure.

**Never collect a dust sample without being completely sure that the
Nilfisk GS-80 and auxiliary equipment have been properly decontaminated
prior to use.**

[7.0]{.smallcaps} QUALITY ASSURANCE/QUALITY CONTROL

With limited sample mass available for primary TAL analyses, duplicate
or replicate sample protocol may not be viable or feasible (if the team
leader determines a duplicate sample is viable, he or she will use the
extra bags supplied by the field office). If viable, duplicate samples
can be taken for 1 in 10-samples.

[8.0 SAFETY PRECAUTIONS]{.smallcaps}

Health and Safety procedures as described and defined in the NDEP Health
and Safety Plan (HASP) must be observed and implemented prior to dust
sample collection. Chemical exposures are not anticipated, and physical
or mechanical hazards are only those that would be found in any typical
household environment.

1.0 SCOPE AND APPLICATION

This standard operating procedure (SOP) outlines the recommended
protocol and equipment for collection of a dry-wipe sample to analyze
potential surface contamination.

This method of sampling is appropriate for surfaces contaminated with
non-volatile species of analytes. Sample size should be determined based
upon detection limit desired and the amount of sample requested by the
analytical laboratory. Typical sample size for this investigation is
95.72 square inches (in^2^). Based upon sampling location, the sample
size may need modification due to area configuration but only one gauze
pad will be used.

These are standard (i.e., typically applicable) operating procedures
which may be varied or changed as required, dependent on site
conditions, equipment limitations or limitations imposed by the
procedure or other procedure limitations. In all instances, the ultimate
procedures employed should be documented and associated with the final
report.

Mention of trade names or commercial products does not constitute NDEP
endorsement or recommendation for use.

2.  METHOD SUMMARY

Since surface situations vary widely, no universal sampling method can
be recommended. Rather,\
the method and implements used must be tailored to suit a specific
sampling site. The sampling location should be selected based upon the
potential for contamination. For this investigation, the recommended
sampling locations are: tube television screens, the top and sides of a
projection television, computer monitor screens, and similar surfaces
that attract dust.

Dry-wipe samples are collected from a measured surface to indicate
surface contamination. While wearing a new pair of surgical gloves, open
a sterile gauze pad and stroke firmly over the sample surface,
vertically and horizontally, to ensure complete coverage. The pad is
then transferred to the sample container, labeled and sent to the
laboratory for analysis.

3.  SAMPLE PRESERVATION, CONTAINERS, HANDLING, AND STORAGE

Samples should be stored in a plastic bag, labeled, placed in a second
plastic bag, and shipped to the laboratory performing the analysis. The
laboratory will provide the shipping labels and containers. The amount
of sample required has been determined in concert with the analytical
laboratory.

4.0 INTERFERENCES AND POTENTIAL PROBLEMS

This method has few signification interferences or problems. Typical
problems result from rough porous surfaces, which may be difficult to
wipe.

5.0 EQUIPMENT/MATERIALS REQUIRED

Equipment required for performing wipe sampling is as follows:

-   Clean plastic bags (Ziploc®)

-   Pre-measured template

-   Field data sheets

-   Sample labels

-   Disposable surgical gloves

-   Sterile wrapped gauze pad (4 in. x 4 in.)

-   Chain of custody records

6.  PROCEDURES

Wipe-sampling is accomplished by using a sterile gauze pad, wiping a
pre-determined, pre-measured area. The sample is packaged in a plastic
bag, labeled, double-bagged and packed in shipping containers provided
by the lab. Each gauze pad is used for only one wipe sample. (Use a
second gauze pad to clean the rest of the surface; see 6.9 below.)

1.  Choose an appropriate sampling surface. Without contacting the
    surface, measure off the designated area or use the pre-measured
    template (95.72 in^2^).

2.  Record the surface area to be wiped.

3.  Don a new pair of disposable surgical gloves.

4.  Open a new sterile package of gauze pads.

5.  Wipe the marked surface area using firm strokes. Wipe vertically,
    then horizontally to ensure complete surface coverage.

6.  Place the gauze pad in a plastic bag.

7.  Seal the plastic bag, attach the label and place in a second plastic
    bag (and place in container [without]{.underline} ice).

8.  Record all pertinent data on the field data sheets.

9.  Using a new gauze pad, clean the remainder of the surface and
    dispose of template and cleaning gauze pad properly.

10. Complete the sampling analysis request form and chain of custody
    record (this can be done by the office staff).

```{=html}
<!-- -->
```
7.  CALCULATIONS

Results are usually provided in pCi/area, or other appropriate
measurement. Calculations are typically done by the laboratory.

8.  QUALITY ASSURANCE/QUALITY CONTROL

The following general quality assurance procedures apply:

All data must be documented on standard chain of custody forms, field
data sheets.

> The following specific quality assurance activities apply to wipe
> samples:

For wipe samples, a blank sample should be collected at one out of every
20^th^ sampling event. This consists of a sterile gauze pad placed in a
sample container done in the home. The blank will help identify
potential introduction of contaminants via the sampling methods, the
pad, and the sample container.

Duplicate samples will be collected at one out of every 10^th^ sampling
event.

9.  DATA VALIDATION

A review of the quality control samples will be conducted and the data
utilized to qualify the environmental results.

10. HEALTH AND SAFETY

Health and Safety procedures as described and defined in the NDEP Health
and Safety Plan (HASP) must be observed and implemented prior to dust
sample collection. Chemical exposures are not anticipated, and physical
or mechanical hazards are only those that would be found in any typical
household environment.

FIELD DATA SHEET E

1.  SCOPE AND APPLICATION

The purpose of this standard operating procedure (SOP) is to describe a
procedure for sampling of radon and radon decay product measurements
found in homes. This method is based on samples collected in
pre-packaged kits manufactured and distributed by Key Technology, Inc.,
P.O. Box 562, Jonestown, PA 17038, Phone (717) 274-8310. Nevada Health
Division (NHD) has purchased the kits and contracted with Key
Technology, Inc. to perform the lab test and provide the results for
this study. Nevada Division of Environmental Protection (NDEP) will
place each kit in the home, collect the kits, and mail them to the lab.

2.  METHOD SUMMARY

The method is based on the sample collected in a test period of 48 to 96
hours (2 to 4 days) in a room where the canister will not be disturbed
and away from drafts, an open door, windows, fireplace, (about 3 feet
distance), etc. It should be placed preferably in a basement or the
lowest level of the home (for multi-level homes), and 1 foot away from
the exterior walls of the home, but not in the kitchen, laundry room,
cupboard, closet or bathrooms. The canister should be placed at a height
of 2 feet above the floor, and the space chosen should have remained
closed for 12 hours previous to the test period (normal entry and exit
is OK).

The "KEY-RAD" kit should be stored in a cool dry place and remain in the
box it comes in until the time of use, then returned to that same box.
Radon and radon decay products long-term exposure rate recommended by
EPA and the Surgeon General is 4 pico Curie intensity per liter (pCi/L)
or below. The average indoor rate is 1.3 pCi/L and the outdoor is 0.4
pCi/L. Nevada is in a region of the U.S. where 9% of the housing units
may exceed 4 pCi/L. This is a naturally occurring product where only a
sample can determine the radon or radon decay products exposure rates
for a particular site.

3.  SAMPLE PRESERVATION, CONTAINERS HANDLING, AND SHIPPING

After the radon sample is collected, the container lid is replaced and
resealed with the gray vinyl tape. Make sure the tape tightly seals the
lid to the can in the same fashion as when it was removed. Record the
date and time on the information card and the FIELD data sheet.
Information card and canister must be mailed to the laboratory within 24
hours. Results are returned to the NDEP and the Nevada Division of
Health for consolidation of all sample results. Results will be included
in the environmental sampling results packet to the homeowner.

4.  INTERFERENCES AND POTENTIAL PROBLEMS

Invalidation may occur in the sampling system if canister is punctured,
not properly placed, overexposed to outdoor air supply, overexposed in
the open mode (over 96 hours) or not delivered to the laboratory in a
timely manner. Use of internal/external air exchange systems (other than
the furnace) such as high volume attic and window fans (swamp coolers)
should not be operated for at least 12 hours prior to and during the
measurement period. Any circulation system that brings outdoor air into
the home should not be utilized.

5.  EQUIPMENT/MATERIALS REQUIRED

The radon sample kit as manufactured by Key Technology, Inc., named
"KEY-RAD-KIT."

6.  PROCEDURE

Radon and radon decay products sampling:

1.  A radon kit, "KEY-RAD-KIT" manufactured by Key Technology, Inc. is
    placed in an appropriate site of the control home (on a hard
    surface, at 2 feet or higher above the floor, not in a kitchen,
    bathroom, laundry room, closet, drawer, cupboard, and not near the
    fireplace, a window, nor a place with noticeable drafts). This test
    should not be run during severe weather conditions (i.e. blizzards,
    hurricane, and high winds). The canister should be exposed to the
    air people breathe.

2.  Remove the vinyl tape from the can and remove the lid. Put the lid
    on the bottom of the can and replace the tape around the can. Do not
    allow the tape to twist or pick up any foreign material.

3.  Place the can on a hard surface with the open side up in the
    selected location (it should not be moved). Record the date and time
    (include AM or PM) on the information form and FIELD data sheet.

4.  After 48 hours (2 days) but no more than 96 hours (4 days), pick up
    the unit, reseal the canister and replace the vinyl tape around the
    seam of the canister. If the vinyl tape is lost, use electrical tape
    to seal the canister (the canister must be sealed or it cannot be
    analyzed). Record the date and time (include AM or PM) on the
    information form and FIELD data sheet.

5.  Record on the information form and the FIELD data sheet the type of
    room where the canister was exposed (e.g. basement, living room,
    bedroom, etc.).

6.  Record on the information form and the FIELD data sheet the level of
    the home where the canister was exposed (e.g. basement, 1^st^,
    2^nd^, etc.).

7.  Mail the kit and the information form (place the yellow copy in the
    box the kit came in, keep white copy for NDEP and NHD), tape the
    mailing box closed (use clear tape over the label address and add
    the NDEP phone number, 775-687-4670, at the bottom).

8.  Place in pre-paid postage box with addresses and mail the canister
    within one day.

```{=html}
<!-- -->
```
7.  QUALITY ASSURANCE/QUALITY CONTROL

    1.  All data must be documented on standard chain of custody
        records, FIELD data sheet, or site logbooks.

    2.  All kits must be placed and collected in accordance with
        operating instructions as supplied by the manufacturer, unless
        otherwise specified in the work plan. The radon sample kit
        should be intact when placed in the home and when picked up, and
        must have documentation completed by the agent of the NDEP.

    3.  Duplicate samples will be taken as 1 in 10-samples. Two (2)
        canisters will be set side- by-side at the selected site and
        returned as specified in Section 6.0 above.

    4.  Blank samples or "unopened canisters" (sample not taken) will be
        returned as 1 in 20- samples.

8.  HEALTH AND SAFETY

Health and Safety procedures as described and defined in the NDEP Health
and Safety Plan (HASP) must be observed and implemented prior to dust
sample collection. Chemical exposures are not anticipated, and physical
or mechanical hazards are only those that would be found in any typical
household environment.

## **FIELD DECONTAMINATION** 

## **STANDARD OPERATING PROCEDURE**

The objective of decontamination procedures is to provide clean
equipment for the retrieval of representative environmental samples. All
decontamination will be done in the controlled environment of the NDEP
Fallon Field office.

The types of equipment that have contact with the soil samples and will
be decontaminated are hand trowels and disposable aluminum trays. Data
collection equipment, such as clipboards, floor area vacuuming templates
and pressure gauges for the Summa Canister will also be decontaminated,
as well as any other reusable equipment which enters the homes, such as
buckets for carrying small items. Decontamination of the dust vacuum
sample collection equipment (Nilfisk) is covered under the dust sample
collection SOP.

PROCEDURES:

####### Field Data Collection Equipment:

Clipboards, area templates, calibration equipment (for Summa Canister)
and other equipment will be cleaned using the following procedures:

-   Wipe with a paper towel

-   Alconox and potable water wash

-   Deionized water rinse

-   Air dry

####### Sampling Equipment:

Equipment used for soil sample collection includes: stainless steel
trowels, disposable aluminum trays and the rinsate blank water transfer
funnel. This equipment will be cleaned using the following procedures:

-   Alconox and potable water scrub

-   Thorough potable water rinse

-   Deionized water rinse

-   Air dry

Sampling instruments will be wrapped in aluminum foil after
decontamination to keep them clean before sampling.

# ATTACHMENT H

# FIELD RINSATE BLANK 

# STANDARD OPERATING PROCEDURE

The objective of the rinsate blank is to provide a laboratory analytical
check on possible sources of contamination of a sample that may be
related to equipment decontamination and sample handling procedures. All
rinsate blank samples will be collected in the field. Samples will be
collected at a rate of one blank per 20 soil samples.

The types of equipment that will have contact with the soil samples and
will be decontaminated are steel hand trowels and disposable aluminum
trays. The funnel used for transferring the rinsate blank to the sample
bottles will also be decontaminated according to procedures. Sample jars
and disposable plastic scoops will also come in contact with the soil
sample. The rinsate blank procedures will encompass all these pieces of
equipment.

Rinsate blanks will be handled, transported and analyzed in the same
manner as the soil samples acquired that day. The rinsate blank is
collected in the field and therefore may also be used to assess ambient
conditions that may potentially affect the sample quality.

At the appropriate field location, de-ionized water is passed over the
disposable and decontaminated sample equipment. This equipment includes:
hand trowels, disposable aluminum trays, sample jars and disposable
plastic scoops.

The water is collected into the disposable aluminum tray and transferred
via a funnel to the appropriate sample jars, based on analysis to be
performed:

-   1-liter poly bottle for TAL metals analysis (sample water preserved
    to a pH of \<2 with dilute nitric acid) and sent to CLP Lab.

-   Two 1-liter amber bottles for Pesticide/PCB and sent to CLP Lab.

-   Two 1-liter amber bottles for Semi-Volatile Organics and sent to CLP
    Lab.

All rinsate samples will be packed in coolers and on ice to 4ºCelsius.
