Louisiana Administrative Code › Title 33 - ENVIRONMENTAL QUALITY › Part VII - Solid Waste › Subpart 1 - Solid Waste Regulations › Chapter 30 - Appendices › Section VII-3005 - Groundwater Sampling and Analysis Plan- Appendix C

Current through Register Vol. 50, No. 6, June 20, 2024
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				  must be withdrawn using dedicated or adequately cleaned equipment for each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
