Each well was located and inspected upon arrival at the site. Using a Solinstm Water Level Meter and/or an oil/water interface probe, each well was then gauged for depth to groundwater, depth to floating product (if present) and total well depth. Gauging devices were decontaminated between each well using a triple-rinse method of tap water and non-phosphate detergent, tap water, and then deionized water. Wells were also gauged in expected order of increasing hydrocarbon concentrations to prevent cross- contamination. The based the analytical results obtained the sampling sequence was on during previous quarters sampling event. Wells showing a petroleum hydrocarbon sheen during gauging or initial purging were not fully purged or sampled only if no sheen was observed following purging and recovery Wells containing floating product were not sampled; the thickness of floating product in these wells was measured and recorded and then the free product was removed by bailing. Groundwater Purging and Sampling. During the semi-annual groundwater sampling performed in March 2000, off-site monitoring wells (SE-MW-51, GMX-MW-60, GMX-MW-61, and GMX-MW-62S), which are constructed with more than 20 feet of submerged well screen, were purged and sampled by Wayne Perry, Inc. (WPI) using low-flow (micro-purge) methods. The purpose of the micro-purge technique was to obtain relatively depth-discrete samples to assess the vertical distribution of MtBE concentrations in wells completed with longer screen intervals. The micro-purge depth-discrete samples were collected using a 2-inch diameter Grundfos Rediflow submersible pump at two vertical depth intervals at each well. The pump was initially lowered to a depth of approximately 5 feet below the measured groundwater surface to purge and collect the first sample. The second sample was collected in the lower portion of the well screen interval at a depth of approximately 90 feet bgs. Purging was initiated and maintained at the lowest rate attainable by the pump to minimize vertical mixing within the well. Water levels were monitored during purging and confirmed that the drawdown during purging was negligible. For the pumping and discharge tubing used by WPI during this sampling program, the lowest flow rate able to be maintained was approximately 500 milliliters per minute, Purging continued until a minimum of two discharge-line volumes were removed and the water quality parameters (pH, SEC, and temperature) stabilized. Following purging at each specific depth, groundwater samples were collected from the discharge line on the and transferred directly into sample containers provided by the pump laboratory. The containers were capped with Teflon msepta, labeled, and placed on ice for transport to American Anal,vtics, a state-certified laboratory located in Chatsworth; California. The pump and discharge tubing were decontaminated between samples with a non-phosphate detergent washwater solution that was cycled through the pump and discharge tUbing followed with a deionized water rinse.. For the on-site monitoring wells, at least three casing volumes of groundwater was removed from each well using a PVC bailer or submersible Pump. During purging, water parameters including pH, temperature, conductivity, and turbidity were monitored to calculate stabilization within 10% of each parameter and ensure that groundwater, representative of the aquifer, was entering the well. The .bailer was decontaminated between each well using a triple-rinse method of tap water and non-phosphate detergent, tap water, and then deionized water. The pump and discharge tubing were decontaminated by cycling the washwater through the pump followed with a deionized water rinse. Wells were also purged in expected order of increasing hydrocarbon concentrations to prevent cross-contamination. After purging, Wells were allowed to recharge to at least 80% of their original capacity prior to sampling. Groundwater samples were collected using a polyethylene disposable bailer attached to clean string. Samples were decanted into containers provided by the laboratory appropriate to the analysis to be performed. The containers were capped with TeflonTM septa, labeled, and placed on ice for transport to American Analytics. New sampling equipment (string, bailer, etc.) was used on each well to prevent the possibility of cross-contamination.

Quality control samples submitted to the laboratory included two duplicate groundwater samples and laboratory-prepared trip blanks. One trip blank was kept in the sample cooler and submitted with each set of groundwater samples to the laboratory. Wayne Perry, Inc. initiated a Chain-of-Custody Recordin the field immediately following sample collection to accompany the samples to the laboratory. LPH Removal. LPH removal was conducted from wells MW-7 and SE-SVE-42C, using the automated LPH recovery system as needed. Removed LPH is stored in a polytank for later transport to a recycling facility. LPH was also removed from wells MW-7, SE-SVE-42C, and SE-AS/VE-47C using a vacuum track and transported off-site immediately. Currently wells are placed online intermittently to due the low LPH thickness and elevated groundwater levels. water this monitoring event was stored on-site in drums and two Waste Disposition. Purge generated during 400-gallon polytanks and was later transported off-site by Asbury Environmental Services. Purge water, although characterized as non-hazardous waste, was transported to DeMenno/Kerdoon in Compton as a hazardous waste for recycling. Removed product and condensate from the HCVES generated during this period was stored on-site in appropriate polytanks. Waste recycling/disposal documentation is attached. ! ! i P:\5825.000.0\5825.005.0\1 sthalff)0\GW-REPORT.doc 4 l!
