Overhead/Lodi Door Co.• -2- • 8 September 1988 MW-1. Pumping of the wells produced water at extremely low rates. Mr. Harvey discontinued sampling and intended to obtain teflon tubing and lower the pumps in the well bore the next day. At a later date he informed me that the wells were not sampled due to a delay in ordering the tubing. I noted that well numbers should be painted on the well covers to avoid any problem with well identification. August Sampling I returned to O/LDC to observe ground water sampling on 10 August 1988 . The pumps had been lowered in the wells approximately five feet. O/LDC had contracted California Geological to perform the monthly sampling. Doug Lee, geologist and a technician were at the facility along with Mr. Harvey. The static water level in well MW-4 had dropped more than a foot since the previous month. August depth to water in MW-4 was 46. 53 feet. The samplers performed with adequate levels of competence during the time I was on site. We discussed the two additional monitoring wells to be installed for completion of the HAR. MW-5 will be located east of the impoundment (Figure 1) , and will be completed in the shallow water-bearing zone. Well MW-6 will be located as close as possible to MW-4 (Figure 1) . It will be completed in the next deeper water-bearing zone. The existence of an extensive aquitard has been proposed based on offsite drillers logs. Logging of MW-6 will help to substantiate the existence of this strata. The condition of the surface impoundment had not changed since the July inspection. INSPECTION SUMMARY 0/LDC has satisfied the cease discharge requirement of TPCA by removing wastes and temporarily covering the impoundment. Work to complete the HAR will proceed soon- Monthly ground water saiapling is continuing. ohn K. Woodling Associate Engineering eologist
