1.0 Background and General Information Neil O.Anderson&Associates, Inc. (NOA) has been retained by Mr. Nick Sikeotis,President, Jessie's Grove Winery, to perform certain technical tasks as required by the Central Valley Region Water Quality Control Board (CVRWQCB) Order No. R5-2004-0079 (Order). The Order requires, among other items, that groundwater monitoring wells be installed around the area used for land application of winery wastewater. Further, the wells are to be sampled,and the samples analyzed,in order to detect any potential degradation of groundwater quality that may be caused by the application of winery wastewater discharge to the land surface.The purpose of this document is to detail the methods and procedures to be used for the installation of monitoring wells, the sampling and analysis of groundwater, and the analysis of monitoring results. Land application of winery wastewater is potentially beneficial to the environment and to the preservation of groundwater resources in that it reduces or eliminates the need for application of artificial fertilizers to the land surface and reintroduces water removed from the aquifer. The subject property is located at 1973 West Turner Road,Lodi, San Joaquin County, California, Section 32,TAN.R.6E. Based on a review of information compiled from various sources (see Appendix A), the site is underlain by the Lower Member of the Quaternary Modesto Formation which is indicated to consist of unconsolidated, slightly weathered gravel, sand,and silty clay. Groundwater is anticipated to occur at 20 feet below ground level, and groundwater flow is anticipated to be toward the southwest under a hydraulic gradient of 5 to 10 feet per mile (0.0014 ft/ft). Surface soils are indicated to be associated with the Tokay fine sandy loam, 0-2% slopes. Figure 1 shows the location of the subject property and local topography as depicted on the USGS 7.5 Minute Quadrangle for Lodi North. Figure 2 shows the facility layout. 2.0 Proposed Monitoring Well Locations Figure 3 is a scaled site map showing the location of the land application area, the existing wastewater collection and discharge system,and the location of proposed monitoring wells.A total of three groundwater monitoring wells are proposed for the site (see Figure 3). The proposed well locations were generally selected to be situated in a triangular pattern surrounding the land application area. Proposed locations for MW-2 and MW-3 are west-southwest and south-southwest of the land application area,and those wells are intended to be down-gradient monitoring wells. The proposed location for MW-1 is east-northeast of the land application area,and it is the proposed designated up- gradient well (see Figure 3). Proposed well locations were selected to allow for future expansion of the land application area. 3.0 Proposed Well Drilling and Well Construction Activities Prior to drilling,well drilling permits will be obtained from the San Joaquin County Environmental Health Department, and a check for any existing underground utilities shall be conducted at the drill 2
