INTRODUCTION <br /> ` Our office was contracted by Mr. Joe Berghold to conduct a soil suitability/nitrate <br /> loading study for the proposed remodeling of the Berghold Winery located at 8215 E. State <br /> Route 12, Lodi,CA(Plate 1). The parcel number of the property is APN 051-030-09 (17.15 AC) <br /> and 051-030-09 (32.21 AC) for a total of 49.36 acres(AC). The winery facility is located on <br /> APN 051-030-09 (17.15 AC) and occupies approximately 1.5 AC of the parcel. Mike Smith <br /> Engineering is the civil engineer for the project. <br /> The soil suitability/nitrate loading study was conducted to determine whether the soils are <br /> suitable for the use of a septic system and to estimate whether the proposed project will impact <br /> ground-water quality. The Soil Suitability/Nitrate Loading Study was conducted was performed <br /> according to the requirements of Section 9-1105.2(d) of the San Joaquin County Development. <br /> Major elements of the field work included the drilling of one(1) percolation test boring and <br /> conducting one(1)percolation test in an area designated for a future septic system. The <br /> percolation test was required by San Joaquin County Public Health Services Environmental <br /> Health Division(SJC PHS-EHD) for project approval. <br /> In addition to conducting a percolation test, a review of published soil information, <br /> geologic maps, and available ground water information was reviewed to determine the suitability <br /> of soils. Due to San Joaquin County Public Health Services, SJC PHS-EHD's concern of nitrate <br /> contamination of shallow ground water in the area, a nitrate loading balance was a requirement <br /> for project approval. The nitrate loading study was conducted to estimate the potential impact of <br /> leaching nitrates from the septic system into ground water. This report presents the results of our <br /> study. <br />
