Ground surface elevation at the Control point("C",shown at the southeast building corner on Figure 2) was assigned a relative elevation value of 20 feet, based on a USGS regional topographic map for Lathrop,CA All ground surface and groundwater elevations are relative to the Control point,i.e.are not surveyed to NAV88 Water samples were tested for volatile organic compounds (VOC) in accordance with the CA LUFT manual guidelines. None of the analytes tested were reported at concentrations greater than laboratory method detection levels in the four water samples (Figure 4).
