quantity of lubricating oil within the well . The uppermost ground water beneath the proposed site occurs under partially confined condi - tions within gravelly or silty sands. Depths to ground water beneath the base of planned burial cell excava- tions is generally greater than 100 feet. Capillary rise is estimated to be less than 5 feet. This estimate is based on data in Lohman (1972) correlating the height of capillary rise within the grain size of unconsolidated soil . As would be expected in a generally fine-grained alluvial deposit, permeability of sediments beneath the site is low. In situ and labo- ratory tests were conducted during EMCON's assessment to determine average permeability values of the unsaturated and saturated zones beneath the site. Permeability values in the approximately 100-foot- thick unsaturated zone range from 1 x 10-6 to 2 x 10-8 centimeters per second (cm/sec) . Results of both in situ and laboratory permeability testing are summarized in Table 2, including results of testing con- ducted by J.H. Kleinfelder and Associates (1986) on the proposed and adjacent properties. A slug test performed in Well G-1 indicated a hydraulic conductivity of 9 x 10-3 cm/sec for the saturated aquifer material . C. GROUND-WATERUALIT Q Y Ground water in the eastern portion of San Joaquin County isenerall 9 Y of excellent quality with low total dissolved solids (TDS) of 120 to 550 parts per million (ppm) . Ground-water chemistry data exists from site assessments conducted by EMCON Associates (1987b) and J.H. Kleinfelder and Associates (10a, 1980b, and 1986) . In addi- tion, chemical testing was conducted by EMCON Associates (1987a) on ground-water samples from wells on and adjacent to the nearby Harney Lane Sanitary Landfill . Results indicate that water from monitoring, domestic, and irrigation wells on and adjacent to the proposed PJ9 9390207.00D
