Soil Sample Collection: <br /> Soil samples were collected in a two inch diameter California modified split-spoon sampler at intervals <br /> of five feet unless sample tool refusal was encountered. The sampler was driven in advance of the augers <br /> to collect relatively undisturbed samples for logging and possible laboratory analysis. Blow counts were <br /> recorded for each six inch interval. Refusal was reached if a total of fifty blow counts were required to <br /> drive the sampling tool six inches. Sampling for that interval was then suspended and drilling was <br /> resumed. <br /> Soil samples from the split spoon were collected in clean brass or stainless steel sampling tubes. Once <br /> retrieved from the split spoon, liner ends were covered with in plastic end caps to inhibit the escape of <br /> water vapor. <br /> All soil samples collected for laboratory analysis were labeled with the location,date and time,and <br /> immediately placed into a cooler chilled to 4 degrees Celsius and containing"blue ice"coolant. All <br /> sampling information was recorded on the boring log forms. <br /> All soil samples were described in the field by the site geologist. Field observations noting sediment <br /> type,color,grain size, sorting, hardness, texture,clay content, moisture content, visible evidence of <br /> contamination, odor,and any other information important to the investigation were recorded in the field <br /> on appropriate log forms by the site geologist. <br /> Soil chemical analysis: <br /> Note: The capability of soil to receive agricultural waste is classified in three categories:slight, <br /> moderate and severe. Each labeling the soils' capability limitations to the applications of agricultural <br /> Soil# 193(Area of other soils is insignificant): <br /> Soil pH: Moderate: Measured, 8.07. <br /> Soils with surface layers with pH greater than 6.5 are considered to be slight. Soils with a high pH can <br /> have it reduced with the continuous,high applications of agricultural waste. <br /> Organic matter: <1%. <br /> Nitrate is held very loosely to the anion exchange sites of the soil and move readily with percolating soil <br /> water. As the organic fraction is impoverished because of poor farming practices, the soil's ability to hold <br /> these elements is drastically reduced. <br /> Salinity,very slight: <2 mmhos/cm. <br /> Soils with <4 mmhos/cm are considered very good for the application of agricultural waste. <br /> Laboratory Analysis of Soil Samples: <br /> Soil samples collected from boring MDS-1 were submitted to Geo Analytical Laboratories in Modesto, <br /> California,(a California State certified analytical laboratory)for analysis of the following constituents <br /> using the stated methodologies: <br /> *Total Kjeldahl Nitrogen(TKN), Method 351.3: Detection Limit 5.0 ug/kg <br /> •Total Nitrate(NO,), Method 300L Detection Limit 1.0 ug/kg <br /> •Total Dissolved Solids(TDS), Method 160.1: Detection Limit 5.0 ug/kg <br /> *Total Phosphate(P), Method 365.2: Detection Limit 0.5 mg/kg <br /> Reference appendix: <br /> Figure 15 Phosphorus/TDS Test @ Profile- MSD-1 <br /> Figure 16 TKN/Nitrate Test @ Profile- MSD-1 <br /> Figure 17 Quality Control Report- Phosphorus <br /> Figure 18 Quality Control Report-TDS <br /> Figure 19 Quality Control Report- TKN/Nitrate <br /> Figure 20 Chain of Command- Soil sample- MSD-1 <br /> 5 <br />
