D. GROUNDWATER INFORMATION 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 2016 Lines of Equal Depth Map indicate the groundwater depth under the property to be approximately 65 feet below grade. In 1983, the depth to groundwater was 70 ft and in 1999 the depth was 60 ft. The Fall 2016 Lines of Equal Elevation Map illustrates the groundwater directional flow to be in a northeasterly direction. NLS§ 2.2,3.1, SSS§ 2.1, 4.2. Since the surrounding properties have been farmed for a number of decades, the potential for nitrate contamination to the underlying groundwater aquifers can be considered significant. NLS§ 2.3, SSS§ 4.3, 4.4, 4.5, 4.6. There are two domestic wells and one irrigation well on the subject Parcel. The well that serves the existing Temple Facility was sampled to quantify nitrate as nitrogen, ammonia-nitrogen, total alkalinity, Ec, and pH concentrations. The following Table summarizes the test results: TABLE 3 TEMPLE WELL: ANALYTICAL RESULTS OF TESTED CONSTITUENTS SAMPLE ID NITRATE AS AMMONIA- TOTAL TOTAL Ec PH NITROGEN NITROGEN NITROGEN ALKALINITY Temple Well 5.62 mg/L 0.0 mg/L 5.62 mg/L 104.0 mg/L 0.337 mmhos/cm 7.1 Page -4- Chesney Consulting
