CENTRAL VALLEY REGIONAL WATER QUALI -,` CONTROL BOARD <br /> INSPECTION REPORT <br /> 17 August 1987 <br /> DISCHARGER: Dallas Corporation, dba Overhead/Lodi Door Co. (O/LDC) <br /> LOCATION & COUNTY: Lodi, San Joaquin County <br /> CONTACT(S) : James Harvey, Dallas Corporation <br /> Steve Raugust, J.H. Kleinfelder (JHK) <br /> INSPECTION DATE: 14 August 1987 <br /> INSPECTED BY: John K. Woodling <br /> ACCOMPANIED BY: ---------- <br /> OBSERVATIONS AND COMMENTS <br /> The purpose of this inspection was to observe the ground water <br /> sampling techniques used by Kleinfelder at O/LDC and to collect <br /> splits of ground water samples to be analyzed for concentrations of <br /> metals. <br /> I arrived at 0930, having been informed on the afternoon of 13 <br /> August that sampling would begin at 0900. No Kleinfelder personnel <br /> were present when I arrived. I met informally with James Harvey and <br /> discussed cleanup of the surface impoundment. Steve Rauaust, the <br /> JHK sampler, arrived at approximately 1045. f made a note to <br /> request ree days notice before any future sampling or other <br /> operations related to the site investigation. This may help <br /> alleviate future miscommunication. <br /> Sampling began with MW-4 , the newly constructed upgradient <br /> monitoring well, and was to proceed with MW-3 , MW-2 and MW-1, <br /> finishing with the well with highest metal concentrations to date. <br /> Monthly sampling had not been performed in June and July. This lag <br /> was the result of ordering and installing dedicated bladder pumps. <br /> Steve Raugust said the pumps were placed at 51 feet depth, which <br /> would be near the center of the saturated portion of the screened <br /> interval. The August ground water monitoring report should include <br /> new well construction diagrams and description of new methods and <br /> equipment. <br /> Water Level Measurements <br /> Static water level was measured with an electronic sounder with both <br /> audible and visible signals. The sounder cable was marked at 1. 00 <br /> foot intervals. The distance from the nearest mark was measured <br /> with a 12-inch engineer's scale. <br />
