Any past agricultural activities and the present use of septic systems in the area should <br /> be considered potential ground-water contamination sources. <br /> t X1.3 Water Sample3 ple Location <br /> � n <br /> fNo well permits were found for the subject property during file review at EHD on January 6,2005. <br /> No water sample was taken because there are no wells on the property. <br /> 5.0 SOIL PROFILE AND GEOLOGIC INFORMATION <br /> i depicted on the Geologic M o the Sara Francisco -San ose uadran le California 9999 as <br /> The Site s p g Map f J Q g , f ( �, <br /> within a region of Quaternary Riverbank Formation.
