S November 1990 -5- M88168D I� \ I Monitoring Well Construction. Drill hole MW-1 was completed as a ground water monitoring well. Monitoring well construction specifications were in compliance with CCR, Title 23 , Section 2647. Monitoring well construction specifications are described in Appendix C, and the monitoring well schematic is contained in Appendix A in conjunction with the monitoring well log. It should be noted that monitoring well MW-1 was completed to a depth ' of 80 feet bgs and currently exist as a dry well. This well may be utilized once the ground water table in the area rebounds to normal, historical, elevations. Ground Water Sampling. On October 9, 1990, a ground water sample was collected from within the hollow stem auger at DH-2 at a depth of approximately 90 feet bgs for laboratory analysis of TPH, BTEX, and total lead. This ground water sample was collected from inside the hollow stem auger because the drill rig had reached its mechanical limit and the construction of a proper ground water monitoring well was not possible (see Appendix C, Monitoring Well Construction Section) .
