'GROUNDWATER INFORMATION r i NLS§ 2.1, SSS§ 4.1. Groundwater depths and elevations throughout San Joaquin County are illustrated on maps published by the County Flood Control and Water Conservation District. The Fall 2010 Lines of Equal Depth Map indicate the groundwater depth to be approximately 80 feet below grade. The Fall 2010 Lines of Equal Elevation Map illustrates the groundwater directional j flow to be in a southeasterly direction. NLS§ 2.2,3.1, SSS§ 2.1, 4.2. Since the subject property and surrounding properties were farmed for a number of decades, the potential for nitrate contamination to the upper groundwater aquifers,B� can be considered significant. However, from extensive studies conducted by EHD, high nitrate groundwater has not been observed in the Morada area. This can be most likely attributed to the , high clay content soil in the surface soils within this area. The on-site well to supply domestic water for the future Church has a nitrate concentration of 16 ppm as nitrate. This is approximately one-third the Maximum Contaminant Level (MCL). NLS§ 2.3, SSS§ 4.3, 4.4, 4.5, 4.6. As referenced, the on-site domestic well was sampled for 6/-v E analysis. The on-site domestic well was sampled from the sampling port on the discharge pipe, with the well located on the east side of the house. The water was allowed to run for 30 minutes �L with the pump cycling several times to ensure that aquifer formation water was sampled and not stagnant well casing or tank water. A nitrate water sample was drawn into a one-quarter liter plastic bottle and the DBCP sample was drawn into three VOC,glass vials with preservative. The four sample containers were placed in a cooled ice chest and then stored overnight under refrigeration. The following day, the samples were transported to A & L Western Agricultural Labs in Modesto, under the attached Chain of Custody found in Appendix F. The constituents tested were for nitrate and Dibromochloropropane (DBCP), with the test results found in Appendix D, and illustrated below in Table 3. 5 Chesney Consulting
