(Live Oak) was contracted by Doug Torres to conduct <br />a Soil Suitability Study and Nitrate Loading Study for the property located at 7942 West <br />Erb Way, Tracy, California (Plate 1). <br />The Soil Suitability Study and Nitrate Loading Study are combined under this report <br />cover and presented as two sections of this report. The formatting of the report has <br />been designed to follow the recommendations of the San Joaquin County <br />Environmental Health Department as described in its Soil Suitability Study <br />Requirements Checklist and Nitrate Loading Study Requirements Checklist. <br />The Soil Suitability Study and Nitrate Loading Study were conducted to determine <br />whether the soils are suitable for use with a septic system, as well as to estimate if the <br />use of septic systems will impact ground water quality.
