Section VII-3005 - Groundwater Sampling and Analysis Plan- Appendix C

Groundwater Sampling and Analysis Plan

A. All wells must be measured for total depth and depth to water on the same day and immediately prior to purging. Measurements must be to the nearest 0.01 foot, and the values must be recorded in the field notebook. If 10 percent of the screened interval is blocked by sediments, the well must be redeveloped prior to the next required sampling event. Wells with dedicated sampling devices that preclude total-depth measurement must be measured annually.
B. Each well must be purged by evacuation to dryness or by removing a minimum of three casing volumes. The well must be sampled immediately upon purging and/or when sufficient water for sampling has recharged the well. Purging and sampling methods must be consistent throughout the life of the facility. Samples shall not be field filtered prior to laboratory analysis.
C. Samples must be withdrawn using dedicated or adequately cleaned equipment for each well. No equipment or method may be used that will chemically alter or influence the sample. Sampling devices, other than bailers, must be approved by the administrative authority prior to use in monitoring programs. Care must be taken to avoid placing clean sampling equipment on the ground or on any contaminated surface. Sampling methods and equipment must be compatible throughout the life of the facility.
D. Sample preservation, handling, and analysis shall meet the specifications of SW-846, or an equivalent substitute as approved by the administrative authority. Parameters, containers, preservation methods, and analytical limits are listed in Tables 1 and 2.
E. Analytical methods with the equivalency to SW-846, or analytical methods for parameters not listed in SW-846, shall be approved by the administrative authority prior to implementation.
F. A chain of custody shall be employed that will allow for the possession and handling of samples to be traced from the time of collection through laboratory analysis. All sample containers shall be labeled to prevent misidentification, have proper seals, and indicate the test parameters required.
G. At the site, an up-to-date field logbook shall be kept, which documents for each sample the well identification number, total well depth, elevation of top of casing, water level, water color, well-evacuation procedures and equipment, date, time, sample identification numbers, field measurements (pH, specific conductance, etc.) and methods, name of collector, field observations, calculations of the standing-water volume in the well, and the total volume evacuated.

NOTES:

1 Common names are those widely used in government regulations, scientific publications, and commerce; synonyms exist for many chemicals.

2 Chemical Abstracts Service registry number. Where "Total" is entered, all species in the groundwater that contain this element are included.

3 CAS index numbers are those used in the 9th Collective Index.

4 This substance is often called Bis(2-chloroisopropyl) ether, the name that Chemical Abstracts Service applies to its noncommercial isomer, Propane, 2,2'-oxybis[2-chloro- (CAS RN 39638-32-9).

5 Chlordane: This entry includes alpha-chlordane (CAS RN 5103-71-9), beta-chlordane (CAS RN 5103-74-2), gamma-chlordane (CAS RN 5566-34-7), and constituents of chlordane (CAS RN 57-74-9 and CAS RN 12789-03-6).

6 Polychlorinated biphenyls (CAS RN 1336-36-3); this category contains congener chemicals, including constituents of Aroclor 1016 (CAS RN 12674-11-2), Aroclor 1221 (CAS RN 11104-28-2), Aroclor 1232 (CAS RN 11141-16-5), Aroclor 1242 (CAS RN 53469-21-9), Aroclor 1248 (CAS RN 12672-29-6), Aroclor 1254 (CAS RN 11097-69-1), and Aroclor 1260 (CAS RN 11096-82-5).

7 Toxaphene: This entry includes congener chemicals contained in technical toxaphene (CAS RN 8001-35-2), i.e., chlorinated camphene.

8 Xylene (total): This entry includes o-xylene (CAS RN 96-47-6), m-xylene (CAS RN 108-38-3), p-xylene (CAS RN 106-42-3), and unspecified xylenes (dimethylbenzenes) (CAS RN 1330-20-7).
