-2- The soils underlying the wastewater pond shall be sampled and analyzed, as well as the sludge in the pond. A systematic groundwater monitoring well construction and samping/ analysis program for the site to define the hazardous constituents and the extent of any contaminating plume in both the shallow and deeper aquifers. Analyses on all samples can be made in a specific sequence with re- spect to vertical characterization, until a clean area is found. However, all surface an immediately subsurface samples shall be analyzed. A minimum of three locations for background samples shall be chosen, and these locations must be approved by the Department. Soil samples shall be taken at surface, 5 feet, 10 feet, 20 feet and 30 feet for each background sample location. All background samples shall be analyzed for total heavy metals, soluble heavy metals using the WET and hexavalent chromium. A description of all soil and groundwater sampling equipment and procedures to be used shall be submitted to the department. All soil samples shall be collected using a hollow stem auger and either a splitspoon or Shelby tube. Split samples shall be provided to the department for all samples collected. The splitting of the samples shall be done by Marley's laboratory. Some field splits will be collected. A groundwater sampling /analysis program for the site to define any contaminated plume in both the upper aquifers and the lower aquifers . c. A quality control/safety element to assure that sampling is all soil and groundwater representative, laboratory analysis is accurate, and procedures prevent exposure to hazardous waste. The laboratory Marley choses to use must be acceptable to the Department. Marley shall provide the Department the use of a contract laboratory for analyses. Marley's laboratory shall follow quality assurance and quality control in accordance with the U.S. Environmental Protection Agency's "Test Methods for Evaluating Solid Waste - Physical/Chemical Methods" (SW 846) , 2nd Edition, 1982. There shall be a chain of custody for the samples from the time of collection until the last analysis is performed.
