Re: Sensitive Receptor Survey Quik Stop# 132 3555 W. Hammer Lane Stockton, CA Dear Ms. McCartney: This report has been prepared by ATC Associates on behalf of Quik Stop Markets. This sensitive receptor survey was performed to identify surface water bodies, and domestic water wells near the site referenced above(Figure 1)in support of a forthcoming request for closure at the site. SENSITIVE RECEPTOR SURVEY ATC performed a sensitive receptor survey within a 2,000 foot radius of the site, Figure 1. The survey included identifying surface water bodies, and reviewing California Department of Water Resources (DWR) records to identify domestic water wells within the survey area. Based on groundwater elevation data for August 24, 2005 the groundwater flow direction in wells, in both the upper and lower screened intervals, was toward the southeast at a gradient of approximately 0.002 feet per foot (ft/ft) and 0.003 ft/ft, respectively. This is consistent with past reports of groundwater flow direction and gradient for this site. FINDINGS Sensitive Receptors: ATC performed a search of the nearby areas for day care facilities, nursing homes, hospitals, and schools. Four facilities were located and are shown on Figure 1 and tabulated in Table 1. Two of the four facilities, located within the search radius, are located down-to-cross-gradient of the subject site at distances of 0.13 mile and 0.42 mile. One facility is located up-gradient and the other facility is located cross-gradient of the subject property at distances of 0.30 mile and 0.09 mile respectively. I Surface Water Bodies: Stockton street maps and the 1993 United States Geological Survey 7 %z minute quadrangle topographic map for Stockton, California were reviewed to identify surface water bodies within the survey area. The surface water bodies identified within the survey area were the North—South arm of Mosher Stough, and a concrete lined community pond. Mosher Slough is located approximately 600 feet to the west, up-gradient of the subject site. The concrete lined community pond is located Sensitive Receptor Survey October 24,2005 Quik Stop # 132 Page 1 of 2 3555 W.Hammer Lane Stockton,CA
