• Hand Auer Borings Five hand auger borings were excavated to collect samples from each of the five dominant soil types present in the area of the teVelde project. The borings were advanced using an AMS soil auger with a 3 1/2 inch diameter auger bit. Each boring was drilled to a depth of approximately one foot below the surface and a sample was retrieved in the bit from the 12 inch to 18 inch depth interval. The sample was immediately packed into a two inch diameter by six inch long brass tube and the ends covered with plastic end caps. Each sample was labeled with the date and time of collection and the site plotted on a USGS 7 112 minute quadrangle map. Laboratory Analysis of Soil Samples One soil sample from a depth of five feet in each boring and the hand auger samples were submitted to A&L Western Agricultural Laboratories in Modesto, California, for analysis of the following constituents: • Organic Matter • Estimated Nitrogen Release • Phosphorus (Weak Bray and Sodium Bicarbonate-P) • Extractable Cations (Potassium, Magnesium, Calcium, and Sodium) • pH • Cation Exchange Capacity • Computed Percent Cation Saturation • Residual Nitrogen as Nitrate-Nitrogen • Soluble Salts • Excess Lime Reference appendix IV B for test results. Soil Physical Properties Analysis - A&L Western Laboratories also performed soil textural analyses on four samples from boring #1, five samples from boring #2, and one sample from boring #3. Reference appendix V C, 1&2. One soil sample from the bottom of each boring was collected for permeability analyses. The samples were retained in the two by six inch brass or stainless steel sleeves and submitted to Sierra Testing laboratories in El Dorado Hills, California. The samples were tested, as received, in the sleeves for Flexible-wall Permeability using ASTM Method #D5084. Reference appendix V E 4 I 24
