6.2 Description of the methods proposed to mitigate any known or future impact to soil and groundwater from nitrate and/or other constituents of concern, at and/or around the project site: The project, as described in this report is sustainable by the site in current conditions. Additions or modifications to the site may require the addition of a waste water treatment system. At the time an addition is proposed, this report should be updated to ensure the adequate improvements are made. 7.0 CONCLUSION AND RECOMMENDATIONS SECTION The conclusions of this report are based on the information provided regarding the proposed development,the use of the subject property,and the site conditions as they existed at the time,we excavated our test holes and performed the percolation test. It was assumed that the test holes and percolation tests and the compiled data results are representative of the subsurface conditions in the general area. The site complies with the San Joaquin County requirement by having a project site with less than 10.0 mg/L-N. The values used for calculations assume that the nitrate concentration of rainfall is 1 mg/L-N as previously noted (Hanztch/Finnermore). Also, the site contains denitrification processes and that based on uses the site effluent stream is 45 mg/L-N. Analyzing all the compiled data, the site is adequate for the proposed use. 7.1 APPENDIX Attachments are all included at the end of this report as part of the Appendix. 8.0 LIMITATIONS Limitations in Nitrate Loading Study: Our services were performed, our findings obtained, and our conclusions proposed in accordance with generally accepted engineering principles and practices. The warranty is in lieu of all other warranties either expressed or implied. Test findings and statements of professional opinion do not constitute a guarantee or warranty, expressed or implied.
