Mr. Andrew A. Woods 14 September 1998 Page 3 using Teflon sheets secured by plastic caps. The sample will then be labeled to indicate a unique sample number, the date and time collected, and the sampler's identification. Labeled samples will be placed into clean Zip-lock bags and preserved in an ice-chilled cooler during transport to a State- certified laboratory for analysis. The end tubes will be used for sample logging, soil classification using the Unified Soil Classification System, and qualitative field screening purposes. The soil samples selected for analysis will be delivered with completed chain-of-custody forms to Excelchem Environmental Labs in Roseville, a State-certified laboratory. Field screening of soil samples will be conducted by monitoring the headspace of sealed plastic bags containing soil samples for the presence of organic vapors. Organic vapors will be measured by a photo-ionization detector equipped with an 11.8 eV bulb. Results of the headspace monitoring and the visual inspections are present on the attached soil boring logs. After the wells are installed and the grout has been allowed to set for at least 48 hours, they will be developed by hand bailing and surging until the water appears free of sediments. The wells will be sampled within two weeks after being developed. Samples will be collected after a minimum of three well volumes are purged and field measurements of pH, electrical conductivity and temperature have stabilized. One field duplicate will be collected and a travel blank will accompany the samples for quality control purposes. Samples will be collected in 40-m1 glass VOA containers which will be labeled as to the collector's identification, the time and date of sampling, and the sample origin. The containers will be stored in a chilled ice-chest during transport to Excelchem Environmental Labs for analysis of chlorinated hydrocarbons. Storaize of Drill Cutting and Purze Water The drill cuttings, development water and purge water will be stored in drums at the All Pure Chemical Company site for subsequent disposal. After receiving the results of the laboratory analyses, we can advise you on the options that are available for disposing of the cuttings and pumped water. Task 2- Collect One Hydropunch Sample One hydropunch groundwater sample will be collected from the location shown on Figure 1. The sample will be collected by first drilling a soil boring to a depth of approximately 9 feet below the ground surface and collecting a soil sample. A groundwater sample will then be collected by driving the hydropunch sampler below the saturated zone (estimated at 10 feet below the ground surface) and retrieving the groundwater sample from the hydropunch sampler with a hand bailer. Protocol for drilling, soil and groundwater sampling, sample preservation, and handling of drilling cuttings will follow the procedures described above for the installation of the groundwater monitoring wells.
