F FI January 27, 2005 NOA Project Number: E04070B F1 Page 2 Three types of wastewater sampling data,influent, effluent, and storage pond,were collected during the year of 2004 to comply with the Monitoring and Reporting Program (MRP) contained within the FI WDRs. Wastewater was not applied to land during this period,but the storage pond water was sampled for the effluent criteria specified by the MRP as though it were to become effluent. All samples were collected and analyzed by the staff of Precision Enviro-Tech of Stockton. i This report should be read in conjunction with the monthly and annual monitoring reports prepared by Morada Produce and submitted each month to the CRWQCB. Attached to those reports are the analytical pages prepared by Precision Enviro-Tech. Physical Setting Groundwater According to the Fall 1998 and Spring 1999 Lines of Equal Depth to Groundmater maps produced by the San Joaquin County Flood Control and Water Conservation District (the most recent published maps available from that source),groundwater occurs at between 90 and 110 feet below ground surface in the vicinity of the subject property. At a site approximately 2.5 miles to the north and at a comparable elevation to Morada Produce, x NOA has measured the depth to groundwater at 106 to 109 feet below ground surface during the p month of January 2005. Soil According to the Soil Survey of San Joaquin County',Morada Produce is located on Hollenbeck silty clay, 0 to 2 percent slopes. The Soil Survey describes this map unit as follows: This moderately well drained, nearly level soil is in interfan basins. .fit is deep to a hardpan. rt formed in alluvium derived from mixed rock sourves.. Typically, the surface layer is grayish brown silty clay about 10 inches thick. The upper 27 inches of the subsoil is brown and yellowish brown clay. The next S inches isgrayish brown silo clay loam. The lowerpart to a depth of 60 inches is variegated lightyelloy ish brown, weakly cemented to stmngy cemented hardpan. Chesney Consulting of Turlock, California,performed an analysis of the on-site soils as part of their C +I 2002 Report of 1Vaste Discharge for Morada Produce Companyz. Chesney collected a soil sample from five feet below the base of the wastewater pond and found it to consist of sandy loam: 57% sand, 36% silt, and 7% clay. Additionally, Chesney advanced a 45-foot exploratory soil boring on the site } and logged the soils as follows: F1I USDA Soil Conservation Service,1992,Soil Survey of San Joaquin County,California.
