NITRATE LOADING STUDY FFNLS4CHEMICAL AND PHYSICAL PROPERTIES OF THE SOIL As referenced in the Soil Suitability Study section, the soil chemical and physical properties are covered in the first four pages of the Phase I Report. Nitrate impact and mitigation within the indigenous soil environment are discussed on Page 3. NLS§ 2.0 GROUNDWATER ANALYSIS Equal depth and elevations are illustrated on groundwater maps published each year by the San Joaquin County Flood Control and Water Conservation District in their Groundwater Report. To observe groundwater data over time, five year intervals were chosen over the past 17 years that reflect both rainy years and drought years. The following Table illustrates the year, depth, and elevation to establish groundwater directional flow under the property. As noted,wet years in the mid-to-late 1990s elevated the water table depth, and the recent drought has had the effect of lowering the water table in comparison to the earlier, wetter years. TABLE 2 YEAR DEPTH ELEVATION AND FLOW DIRECTION Spring 2000 55 ft -25 ft, East-northeast Spring 2005 68 ft -38 ft, East Spring 2010 70 ft -35 ft, East-northeast Spring 2014 68 ft -35 ft, East-northeast Spring 2015 70 ft -35 ft,Northeast Fall 2016 80 ft -50 ft,Northeast In June 2015, Senate Bill 83 amended California Water Code §13752 to allow public access to Well Completion Reports. However,the law requires the Department of Water Resources to comply with The Information Practices Act of 1977, redacting personal information from the Well Completion Reports before making them public. Since there are about 800,000 reports on file with the Department, it requires a significant effort to redact the personal data from all reports. Consequently, lithology underlying the property could not be discerned through these well logs. The EHD no longer has any of these Reports since they are now under the control of DWR.
