Perched water was encountered in the 25 foot deep borehole <br /> located on proposed parcel one. The water appeared to be located on top of a localized hardpan <br /> layer. <br /> Ground Water Contamination Issues in the Area <br /> Potential groundwater issues in the area consist of contamination from leaching of <br /> agricultural chemicals, dairy manure ponds, fuel tank leakage, septic system usage and storm <br /> water infiltration. <br /> Water Sample Location <br /> A water sample was collected from the domestic well located onsite adjacent to the garage on <br /> March 24, 2009. A faucet is located adjacent to the well head and was used to collect the ( 3) <br /> sample. <br /> Water Sample Constituents <br /> Samples where sent to Argon Laboratories in Ceres, California and analyzed for Total Nitrogen <br /> and DBCP (1,2-Dibromo-3-chloropropane). The Results reported 14.2 mgll of Total Nitrogen as <br /> N d 1.0 ug/L b) of DBCP. California MCL for Total Nitrogen is 45 mg/L and for DBCP is ( �� <br /> 0.2 u <br /> Water Sampling Handling <br /> The water sample was collected in laboratory provided sample containers. The well was <br /> allowed to flow for about fifteen minutes prior to collection of the sample. The sample port only <br /> allowed collection of the water sample when the well was actively pumping. The samples where <br /> JR SQUARED CONSULTING,INC. ENVIRONMENTAL-ENGINEERING•GEOLOGY <br /> 6532 MCNEIL COURT,VALLEY SPRINGS,CA 95252 PHONE(209)772-3841 •FAX(209)740-4303 <br />
