Odyssey Landscape—Soil Suitability Section Page 6 of 13 <br /> Our Project Number: NA157000 <br /> March 17, 2015 <br /> Sample results are displayed in the following table: <br /> DBC /L EDB* (ug/L Nitrate as N** m /L _ <br /> Water Sample 1 ND ND <br /> — Water Sample 2 x 7.3 <br /> *EPA method 524.3 <br /> **EPA method 300.1 <br /> ND-non detect. <br /> x-represents that the sample was not tested for the constituent. <br /> The United States Environmental Protection Agency (EPA) sets the maximum contaminant level <br /> (MCL) for DBCP at 0.2 ug/L and for EDB at 0.05ug/L. As indicated in the foregoing <br /> investigation, both DBCP and EDB were non detected. The EPA sets the MCL for nitrate at 10 <br /> mg/L. The nitrate level in the tested result was 7.3 mg/L, which is below the MCL. -N which is <br /> below the MCL set by the United States Environmental Protection Agency of 10 mg/L-N. <br /> 1.5 Soil Profile and Geologic Information <br /> The site is depicted on the Geologic Maps of the Sacramento-San Joaquin Delta, California, as <br /> within the alluvium of the Modesto Formation2. These Pleistocene soils consist primarily of <br /> compact silt and very fine sand (Plate 5). <br /> The surface and near surface soils located at the site are reported by the United States <br /> Department of Agriculture (USDA) Soil Conservation Service (Plate 6) to be composed of <br /> Acampo sandy loam3, consisting of moderately well-drained sandy loam derived from granitic <br /> sources. <br /> 1.5.1 Soil Boring Locations <br /> _ A total of one (1) soil boring was advanced on the Site for percolation performing a percolation J <br /> test. The location of the borings is depicted in Plate 1. <br /> 1.5.2 Soil Boring Dimensions <br /> The soil boring was advanced to 3.25 feet bgs, as noted above, and four (4) inches in diameter. 2 <br /> 1.5.3 Soil Lithology Observed <br /> The table below presents the soil log for the soil boring. <br /> 2 USGS.Atwater, B.F.Geologic Maps of the Sacramento-San Joaquin Delta,Sheet 12.MF 14-01. 1982. 1:24,000. <br /> 3 USDA.
