Soil Suitability / Nitrate Loading Study Cherokee Memorial Park Vineyard Chapel Addition ■ Lodi, California March 5, 2021 ■ Terracon Project No. NA207102 Responsive ■Resourceful ■Reliable 4 the break room, janitorial and flower prep needs. Septic system design should be based on the San Joaquin County On-Site Wastewater Disposal Standards or other engineering recommendations.” The 2015 SSS indicated a groundwater sample collected from the onsite well was analyzed for Nitrate as Nitrogen (N) and Dibromochloropropane (DBCP). Nitrate as N was reported at 0.12 milligrams per liter (mg/L) and DBCP was reported below laboratory reporting limits. The 2015 SSS additionally indicated, two shallow percolation test borings were advanced in the area of the primary (P1) and secondary (P2) leach fields, at approximately three feet below grade surface. Soils consisted of brown fine silty sand. Both soil percolation tests P1 and P2, demonstrated satisfactory percolation rates of 15.63 and 20.83 minutes per inch respectively. The report indicated a prior geotechnical investigation (Project Number NA145054) did not identify groundwater in borings advanced to 16.5 feet bgs. n Neil O. Anderson & Associates, a Terracon Company, Nitrate Loading Study (NLS), Cherokee Memorial Park Chapel, 14165 North Beckman Road, Lodi, California dated January 14, 2015 (Project Number NA145063). The 2015 NLS was prepared for a 13.25-acre parcel APN 061-030-47 and the Vineyard Chapel development and future development. The following information was obtained from the report, soil denitrification factor (20%), rainfall volume (5.16 inches/year), rainfall nitrate concentration (1.0 mg/L-N), waste effluent quantity (employee/13 gallons per day[gpd] and visitor/5 gpd), waste effluent nitrate concentration (85 mg/L-N), average daily flow (1,614 gpd and 2,337 gpd). Nitrate loading results were reported at 17.1 mg/L-N and 22.1 mg/L-N above the maximum drinking water contaminant level (MCL) of 10 mg/L. n Neil O. Anderson & Associates, a Terracon Company, Engineered Septic System (ESS), Cherokee Memorial Park Chapel, 14165 North Beckman Road, Lodi, California dated August 17, 2015 (Project Number NA157002G). Based on a review of the report, with the approval of the EHD, the waste effluent quantity for a visitor was reduced from 5 gpd to 2 gpd. The average daily flow for the Vineyard Chapel was revised to 669 gpd. The nitrate loading calculation was revised to 7.2 mg/L-N, below the MCL of 10 mg/L. 1.1.1 Site Description The site consists of an approximately 51.18-acre tract of land located at 13951 North Beckman Road, Lodi, California, San Joaquin County, California, Assessor Parcel Number (APN) 061-030- 71.Based on client interviews and a review of the historical information, the site is a cemetery established in 1940 and is improved with approximately ten buildings, seven septic systems, one domestic groundwater well, two irrigation wells, utilities, landscaped gardens, mausoleums and monuments. The following table includes a list of the reported buildings and septic systems currently located on the site.
