1.0 INTRODUCTION <br /> Ramage Environmental has prepared this Groundwater Monitoring Report for the Third Quarter <br /> of 1999, as requested by Mr. Al Vigil of the San Joaquin Catholic Cemetery. The scope of work <br /> .r was reviewed and supervised by Mr. Harlin Knoll of the San Joaquin County Public Health <br /> Services Environmental Health Division (PHSIEHD). The cost to complete the scope of work <br /> was pre-approved on May 27, 1999 by the Underground Storage Tank Cleanup Fund (USTCF), <br /> L <br /> under Claim #1092. <br /> ►r 1.1 Site Description <br /> The subject property is an operating cemetery located on the northeast corner of Harding Way <br /> 6. <br /> and Cemetery Lane in the city of Stockton (San Joaquin County), California (Figure 1). The <br /> project site is located on the east side of the mausoleum building (Figure 2). <br /> 1.2 Previous Work <br /> On November 17, 1989, two underground gasoline storage tanks (UST) and associated <br /> pumping equipment were removed from the site. Based on evidence of impacted soil and <br /> groundwater beneath the site, a total of seven groundwater monitoring wells, two soil vapor <br /> extraction wells and two soil vapor extraction well nests have been installed. <br /> Groundwater has been sampled at the site since August 1990. A dramatic rise in groundwater <br /> elevation since well installation in the early 1990s has resulted in groundwater table levels above <br /> �.. the screened interval of the original five groundwater monitoring wells. The rise in groundwater <br /> elevation also resulted in static groundwater entering the deep soil vapor extraction wells. <br /> On April 28, 1998, Ramage Environmental installed two groundwater monitoring wells (MW-6 <br /> and MW-7) to re-establish a groundwater table monitoring and sampling capability at the site. <br /> +- Currently, groundwater is sampled from MW-6, MW-7 and the two deep vapor extraction wells. <br /> rr. <br /> On May 20, 1998, Ramage Environmental published a Problem Assessment Report and <br /> Corrective Action Plan for the site. Soil vapor extraction and air sparging were recommended as <br /> the most efficient and practical remedial alternatives. On September 8, 1998, the USTCF pre- <br /> approved the cost to construct and operate a soil vapor extraction and air sparging system at the <br /> site. The San Joaquin Catholic Cemetery has contracted with ENSR to complete the pre- <br /> approved scope of work. <br /> 3 <br />
