Washington, Stockton, site. The changes to the ori- <br /> ginal work plan include discrete rather than composite sampling for surface <br /> soils, additional soil sampling in the area where storage containers are <br /> located (at the southern boundary of the property) , and drilling of an addi- <br /> tional groundwater monitoring well and soil boring adjacent to a suspected <br /> second underground fuel storage tank. The approximate locatio.n of this well <br /> and boring is shown on the attached figure. Drilling, construction, and sam- <br /> pling for this well will be performed as described in the original Work Plan. <br /> Changes in the Work Plan were made to incorporate comments from the Department <br /> of Health Services and the Central Valley Regional Water Quality Control <br /> Board. Additional information was obtained about the possible presence of a <br /> second underground storage tank. In addition, information recently supplied <br /> to us about the contents of the storage containers has prompted us to collect <br /> additional samples and analyses near this area. <br /> Should you have any questions concerning the amended Work Plan, please call <br /> me. <br /> Very truly yours, <br /> KENNEDY/JENKS/CHILTON <br /> Mark S. Dockum, R.G. <br /> Project Geologist <br /> Attachment <br /> cc: Mr. Ed James, Central Valley Regional Water Quality Control Board, <br /> Sacramento <br /> Mr. Bill Kilgore, Department of Health Services, Toxic Substances Control <br /> Division, Sacramento <br />
