I. INTRODUCTION This report issues our findings regarding the Nitrate Loading Study for the Beneto, Inc. project which encompasses all three Site Approvals referenced above. The Site Approvals have the preliminary address of 10842 South Harlan Road, French Camp, CA. The APN is 193-330-28. This study is required by the San Joaquin County Department of Environmental Health(PHS- EHD) and complies with the San Joaquin County Development Title, specifically Section 9-1105.2(d). Mr. and Mrs. Steve and Darlene Beneto are the owners of the project. Additional information to complete this study was provided by Mr. Roger Liston of Beneto, Inc. All three Site Approval projects have been issued septic system installation permits and are developed or in the stages of development as of the date of this report. The subject property is located east of Interstate 5, near the intersection of Harlan and Roth Roads. Harlan Road is the frontage road to Interstate 5. The entire property is composed of approximately 29 acres. This acreage does not include an eight-acre parcel in the northeast comer of the subject property and nine-acre parcel in the southeast comer. These areas are currently undeveloped and are not considered in the areal nitrate loading calculations. The 29 acres does include the Kenworth Truck Sales facility in the southwest corner of the property and the Nestle's facility in the northwest comer. Although these facilities are not a part of this project with respect to the Site Approvals, nitrogen contributions from these businesses will be included in the calculations to quantify nitrate loading on an areal basis. The Soil Suitability Study for this project was completed by Wong Engineers, Inc. The purpose of this report is twofold: First, it is known that the top aquifer under the project is heavily contaminated with nitrate. This study has attempted to determine the source(s) of the high nitrate concentration. Secondly,this report specifies septic systems for each of the three Site Approvals which have been designed to protect groundwater underlying the site, based on contemporary scientific studies. III. NITRATE LOADING STUDY RESULTS A. SUBJECT PROPERTY AND SURROUNDING STUDY AREA INFORMATION The subject property and surrounding land use was primarily in agricultural production prior to development. This is evidenced by the attached United States Department of Agriculture (USDA)aerial photograph for the San Joaquin County soil map. The aerial photo taken in the early 1970s illustrates row crops (or pasture) and an orchard. It is known that the nine acres referenced above was a cherry orchard and that a plant nursery was in the same location as the Kenworth facility. The current surrounding land use is composed of commercial operations to the south and north, the SP Railroad and residential to the east, industrial to the south and agricultural to the west. From this past and present, on-site and surrounding land use, it is well documented that any one or more of these land uses could have contributed to the underlying nitrate contamination.
