AS Problem Definition/Background

The EPA New England, Office of Environmental Measurement and Evaluation (OEME), at the request of the site project manager, will collect indoor air, ambient air, and/or soil gas samples at various locations to characterize air quality for the target organic compounds of interest inside buildings of concern.

This may include residential homes or commercial buildings that are situated above or adjacent to a groundwater plume contaminated with volatile organic compounds (VOCs) , ambient air samples to monitor a clean-up operation, hazardous air pollutants (HAPs) being emitted from a facility, and/or measure soil gases in the vadose zone.

The specific site history, background, and contaminants of concern (COCs) will be included in the addendum or SAP, see Appendix B.

A6 Project !Task Description

The study will focus on collecting indoor air, ambient air and/or soil gas samples from various sampling locations identified by the EPA Project Manager and Air Engineer. Samples could be analyzed in the field and/or at the EPA New England Regional Laboratory (NERL) depending on the project scope. The numbers of samples to be collected are based upon the data quality objectives. The target analytes and their reporting limits are presented on Tables I and 2 of this QAPP.

The indoor air, ambient air and soil gas data will be used to help EPA and State Agencies detennine if ambient and/or indoor air quality are being adversely impacted and what actions are needed.

The specific site infonnation for the number, type of samples, and sample collection rationale will be included in the addendum or SAP, see Appendix B.

A 7 Quality Objectives and Criteria

The objective of the study is to collect data of known quality to help EPA, States, and other interested parties detennine if the air quality is being adversely impacted and what actions are needed.

Group B Data Generation and Acquisition

Bl Sampling Process Design

The EPA Project Manager will provide the sampling locations and obtain the necessary access agreements prior to the study.

The specific sample rationale information will be described in the addendum or SAP, see Appendix B.

B2 Canister Methods

The EPA Region 1 Standard Operating Procedure for Canister Sampling, ECASOPCanisterSampling.SOP.Rev4, August 31,2007, will be used to collect air samples. Soil gas grab samples will be collected in evacuated 6 or 15 liter canisters using the procedure described in Part 1 of the SOP, referenced above. The time-weighted average (TWA) indoor and ambient air will be collected in evacuated 6 or 15 liter canisters using mechanical flow controllers following the procedures described in Part 2 or Part 3 of the SOP. Detailed descriptions of the quality assurance procedures are provided in Section 14 of the referenced SOP.

B2.1 Canister Cleaning and Leak Certification

B2.1.1 Canister Cleaning Procedure

Prior to the sampling event, all the canisters will be cleaned by placing them in ovens maintained at 150°C, evacuated to at least 10.2 Torr, and then pressurized with humidified nitrogen to approximately 30 psig. This process will be repeated three times. Detailed descriptions of these procedures are provided in the document entitled, Canister Cleaning Standard Operating Procedures, ECASOP-CanisterCleaning.SOP.Rev5, March 16,2009.

B2.1.2 Canister Leak Certification Procedure

At the end of the cleaning process described above, the canisters will be evacuated to less than 10.2 Torr, the vacuum in each canister will be measured with a Pirani sensor. The canisters will then be placed on a shelf for at least 24 hours. At the conclusion of this period, the Pirani sensor will be used again to measure the final canister vacuum which will then be compared to the initial reading to determine if the canisters show signs ofleaking. Detailed descriptions of these procedures are provided in the document entitled, Canister Leak Certification Standard Operating Procedures, ECASOP-CanisterLeak.SOP.Rev3, August 9, 2007.

B2.1.3 Canister Cleanliness Certification Procedure

After all the canisters are certified leak fj'ee, each canister will be pressurized with humidified nitrogen and then analyzed for contamination using the same GC/MS used for the sample analysis. Detailed descriptions of these procedures are provided in the document entitled, Pressurized Canisters for Clean Certification Standard Operating Procedures, ECASOPCanisterPressurizing.SOP.Rev4, August 9, 2007. Canisters are stored under pressure until a few days before the sampling event, when they will be re-evacuated to less than 10.2 Torr. Detailed descriptions of these procedures are provided in the document entitled, "Canister Evacuation Standard Operating Procedures, ECASOP-CanisterEvacuation.SOP.Rev3, August 28, 2007."

82.2 Canister Sampling

82.2.1 Grab Sample and Time-Weighted Average (TWA) Sample

A canister grab sample is a sample that is collected for approximately one minute. The canister is initially at a pressure of -30 psig and after the canister valve is opened the sampled air is drawn into the canister until the canister pressure reaches atmospheric pressure (0 psig). Grab samples will be collected either in the ambient air, indoor air, or as a soil gas sample.

A TWA canister sample is collected in a similar manner as a grab sample, except a mechanical flow controller is connected to the canister inlet and calibrated to a flow rate so that at the end of the TWA sampling period, the final canister pressure should be below atmospheric pressure, between -8 and -6 inches of mercury ("Hg). lfthis criteria is not met, the data collected using that canister will not be considered representative of the average concentration for the sampling period. Detailed descriptions ofthese procedures are provided in the document entitled, Canister Sampling Standard Operating Procedures, ECASOP-CanisterSampling.SOP.Rev4, August 31, 2007.

82.2.2 Indoor Air Sampling

Indoor air samples will be collected over a predetermined period of time from the basement in a location that is expected to have the highest levels of target compounds. If a portion of the basement is used as living space, a sample will also be collected from this area. Indoor air grab samples will be taken with a syringe and/or canister from areas expected to be points of entry for gases to migrate into the basement and at the same location the canister samples are collected. Detailed descriptions of these procedures are provided in the document entitled, Canister Sampling Standard Operating Procedures, ECASOP-CanisterSampling.SOP.Rev4, August 31, 2007.

82.2.3 Soil Gas Sampling

Soil gas samples are collected using the following procedure: A 1/2 inch diameter steel rod/slam bar is driven into the ground to a depth of approximately 4 feet or to a depth before encountering an obstruction, and then carefully withdrawn to prevent the hole from collapsing. A 1/4 inch diameter copper tube, with a "T" fitting on the end, is inserted into the hole to the desired depth. Native soil is used to form a tight seal at the point where the copper tube exits the ground. If native soil can not be used, clay is placed around the copper tube to form the seal. After the sampling probe is in place, a battery operated portable vacuum pump, calibrated to approximately 1 liter per minute is attached at the end of the "T" fitting to purge the sampling probe for a minimum of I minute before collecting the sample. A magnehelic gauge is incorporated into the sampling system to monitor pressure drops and to ensure a representative sample is collected. The pump continuously withdraws soil gas as a sample is collected. This is accomplished by inserting the needle of a glass syringe through the septa of the "T" fitting and extracting a sample from the soil gas path. The sample is then manually injected into the Photovac GC or Shimadzu GC and immediately analyzed on-site using Region I 's standard air screening method, Air Sample Analysis for Volatile Organic Compounds, EIASOPFLDGRAB4.

At selected soil gas sampling locations, the 1/4 inch copper tube remains in the same position and a new "Too fitting, made of a stainless steel flexible line and an in-line valve, is connected for collecting a canister grab sample. The vacuum pump is attached to the one end of the "Too fitting and the canister connected to the other end of the 'T' fitting. The canister valve remains

Project Title: Generic Air Toxics QAPP Revision Number: 4 Date: I 111711 0 of44

closed as the pump purges the copper tube. Immediately after the in-line valve on the pump end of the "T" fitting is closed, the canister valve is opened to collect a grab sample. Detailed descriptions of these procedures are provided in the document entitled, Canister Sampling Standard Operating Procedures, ECASOP-CanisterSampling.SOP.Rev4, August 31, 2007. All the soil gas canister grab samples are then brought back to the NERL for analysis.

The procedures to collect a sub-slab soil gas sample below a buildings concrete slab are described in the document entitled, SOP for Sub-Slab Soil Gas Sampling, ECASOPSubSlabSoilGasSamplingSOP Revl, August 1,2007.

B2.2.4 Background Ambient Air Sampling

One TWA ambient air canister sample, per sampling day, will be collected from an area adjacent to one ofthe residential properties identified for sampling or upwind from the site. Detailed descriptions of these procedures are provided in the document entitled, Canister Sampling Standard Operating Procedures, ECASOP-CanisterSampling.SOP.Rev4, August 31,2007.

B2.3 Canister Flow Controller Cleaning and Calibration

B2.3.1 Flow Controller Calibration Procednre

All flow controllers will be calibrated to a predetermined flow rate so that at the end of the TWA sampling period, the final canister pressure should be below atmospheric pressure, between -8 and -6 inches of mercury ("Hg). The calibration procedure will take place at the EPA NERL following the procedures provided in the EPA Region 1 Standard Operating Procedure for Canister Sampling, ECASOP-Canister Sampling SOP, Rev4, August 31, 2007, Section 14.l. The flow controller is connected to a "dummy" evacuated canister and an Aalborg Electronic Mass Flow Meter, Model GFMs-O I 0020 or other flow measuring device is attached to the flow controller's inlet port. As room air is drawn into the canister, the flow controller needle valve is adjusted until the flow rate is maintained at the desired rate.

B2.3.2 Flow Controller Cleaning Procedure

After the flow controllers are calibrated they will be cleaned. The flow controllers will be placed in ovens maintained at 100°C and purged with humidified nitrogen for approximately one hour. Detailed descriptions of these procedures are provided in the document entitled, Flow Controller Cleaning Standard Operating Procedure, ECASOP-FlowControllerCleaning.SOP. RevO, September 13, 2007.

B3 Sample Handling and Custody

Field notes and the Chain of Custody form, Figure I, will be completed by the field engineer. All canister samples will be logged into the laboratory immediately upon arrival, transferring the sample custody to the laboratory personnel according to the EPA login procedure, Sample Login. Tracking, and Sample Disposition, EIASOP-ADMLOGI3, Rev13, March 24, 2006. Figure 2 is the laboratory's login checklist. Canisters will be stored on the shelves in the hallway outside Room 173.

84 Analytical Methods

84.1 Field Methods

Field screening using the portable gas chromatograph is used for tentative identification and quantitation of volatile organic compounds in air samples. This screening technique can provide quick and reliable results to assist in important on-site decision making. Table 1 is a list of the routine target VOCs and estimated reporting levels. The EPA method is Air Grab Sample Analysis for Volatile Organic Compounds, EIASOP-FLDGRAB4, August 21,2007. This method can be used to provide analytical data in a timely manner to help direct ongoing field work. Based on the project's data quality objectives (DQOs), the operator can modify some conditions. For example, the injection volumes can be changed depending on the levels found at the site.

An aliquot ofthe air sample is injected into a calibrated gas chromatography (GC) equipped with a photoionization detector (PID) and electron capture detector (ECD). The compounds are separated on a mega-bore capillary or packed column. Retention times are used for compound identification and peak heights are used for quantifying the identified compounds.

84.2 Fixed Laboratory Analytical Methods

The TWA samples and selected canister grab samples are analyzed using a gas chromatograph/mass spectrometer (GC/MS) following the EPA Region I standard operating procedure entitled, Standard Operating Procedures for the Analysis ofVolatile Organic Compounds in Air by GC/lon Trap Detector, Revision 9, August 6, 2007, a modification of EPA Method T015 - The Determination of Volatile Organic Compounds in Ambient Air using SUMMA Passivated Canister Sampling and Gas Chromatographic Analysis, from the Compendium of Methods for the Determination of Toxic Organic Compounds in Ambient Air, EPA-600/4-84-041. This analytical procedure will be used to identify and quantify the VOCs listed on Table 2.

86 Instrument/Equipment Testing, Inspection, and Maintenance

Maintenance logs are kept for all the instruments and equipment. An inert carrier gas is constantly flowing through all chromatographic equipment. Before field operations begin, a standard is run on the gas chromatograph (GC) to insure the GC is operational. The gas chromatography mass spectrometer (GC/MS) has a maintenance contract for the operation. Additional information is located in the laboratory quality management plan (QMP).

B8 Inspection/Acceptance of Supplies and Consumable

The ECA section has an inventory list of all the canisters, which is checked periodically. The analytical supplies and chemicals are routinely ordered by the laboratory personnel.

B9 Non-Direct Measurements

Meteorological data, such as air temperature, barometric pressure, relative humidity, wind direction, and wind speed, may be collected and reported in the final report, if required. The meteorological data can be measured at the study location by EPA personnel using in-house equipment or obtained from the nearest meteorological station, (i.e. airport) only if it represents the conditions for the study area.

BIO Data Management

All of the data, both hard copy and electronic, and the completed chain-of-custody forms are stored at the EPA New England Regional Laboratory (NERL) in North Chelmsford, MA for at least 6 years. This includes the sample dilutions, instrument logs, calibrations, and sample analyses. All field notes are written in a field log book by the air engineer and stored at NERL.

Project Title: Generic Air Toxics QAPP Date: 11117110


Group C Assessment and Oversight

CI Assessment and Response Actions

Project assessments are accomplished by EPA personnel through the quality control program. Typically, the air engineer evaluates the overall project by reviewing both the field and analytical data. If warranted, the EPA project manager can request the quality assurance unit perform a formal audit on the project. This audit will include a proficiency test, review of the field notes, compliance with the sampling and analytical standard operating procedures, and a final assessment report.

C2 Reports·to Management

For field analyses, any instrument problems or discrepancies with the quality control criteria are documented and immediately reported to the air engineer or project manager. The project manager will decide the severity of the problem and decide if the study will continue or stop until the situation is resolved. If the quality control is satisfactory, the field data is reported to the air engineer or project manager. At the end of the day, all the data is reviewed for outliers or data gaps.

The final results ofthe study will be presented in a report prepared by the air engineer and provided to the project manager for review. The project manager will forward the report to the appropriate parties within EPA, States, and all other interested parties. The final report will describe where samples were collected, any modifications, and the sampling and analytical procedures used for the study. In addition, all the sampling and quality assurance/quality control (QNQC) data will be reported in tabular fonn. The collected data will be validated following the QC criteria described in Section B5. The air sampling and analytical techniques used for this study will provide the data necessary to assist EPA and States with evaluating the air quality. Examples of reporting tables are provided in Appendix A. The project will be considered complete upon submission of the final report to the project manager. If additional data are needed, a modification will be developed.

Project Title: Generic Air Toxics QAPP Revision Number: 4 Date: 111 17/] 0 of44

Group D Data Validation and Usability

DJ Data Review and Verification

The field data is reviewed on-site by the air engineer or project manager as to the site's target levels, relative concentrations, and completeness. The project manager will decide if a field duplicate, or subdividing a sampling grid for more information, is necessary.

The NERL EIA personnel use the Project Review Fom1, Figure 3, to ensure the data folder is complete, the chain of custody is included, and the holding times are met. This data package will contain information used to validate the reported data.

D2 Data Evaluation and Data Validation

The validation process is used to accept, qualify, or reject data. The NERL ErA personnel use the Project Review Form, Figure 3, to validate the laboratory data. The data reported by the laboratory will be compared to the measurement performance criteria specified in Quality Control Section, BS, to evaluate the data's usability. All data will be reported and qualified as needed. The air engineer will review the whole project from the beginning to the end: weather, sampling locations, flow rates, and the validated analytical data. All of the variables will be combined with regard to the project's data quality objectives and any issues will be discussed with the project manager. The study will be repeated, ifthere are major discrepancies, data gaps, or more information is needed. The final project report prepared by the air engineer will contain all pertinent documentation, any limitations of the project, and the reported data.

D3 Reconciliation with User Requirements

The air engineer will determine if the 90% completeness goal has been satisfied, the data quality objective (DQOs) have been fulfilled, and if the reporting limits were below State Air Regulations, the EPA Regional Preliminary Remediation Goals, and other predetermined site specific action limits. Based on this information the project manager will determine if more data is required. This information will be included in the final report.

1. Introduction

This SAP is an addendum to the QAU approved Generic Air QAPP, revision 2, October, 2007, RFA # 08002.

In this section include SAP distribution li st and purpose of SAP.

2. Background

In this section provided information on the site, history, hot spots, recognized environmental conditions or areas of concern, contamination of concern, previous investigations including data and sample locations, observations, etc.

3. Project Description/Objective

In this section add the target compounds, field screening, dynamic screening, and health risk criteria.

4. Sampling Design

This section should include infonnation as to the sampling locations and various chemical analyses, and rationale for that location.
