Soil Suitability/ Nitrate Loading Study <br />Lease Property ■ Acampo, California <br />December 17, 2021 Terracon Project No. NA217090 <br />Ircerr on <br />mg/L-N. Groundwater sample GW -2 reported below laboratory reporting limits of 0.010 <br />micrograms per liter (ug/L) for DBCP. <br />Based on the nitrate loading balance, nitrate levels for the existing residence is 4.0 mg/L-N below <br />the MCL of 10.0 mg/L-N. The proposed three bedroom modular is anticipated to increase nitrate <br />levels to 6.4 mg/L-N, also below the MCL. <br />In summary, the parcel appears suitable for the proposed development. The septic system design <br />should accommodate peak flows and follow the San Joaquin County OWTS standards where <br />applicable. <br />4.0 LIMITATIONS <br />As indicated, our study takes into account the subject property only with the sewage load applied <br />over the property site area. The study does not take into account surrounding properties and/or <br />lands. The method utilized for the nitrate loading analysis is based on a simple mass balance <br />formula, discussed in a published article by Hantzsche and Finnemore (1992), which provides a <br />convenient and simplified method to estimate long-term groundwater nitrate impacts on an area - <br />wide basis. Amore detailed analysis was not requested nor intended. <br />Our professional services were performed, our findings obtained, and our conclusions proposed <br />in accordance with generally accepted engineering principles and practices.

Test findings and statements of <br />professional opinion do not constitute a guarantee or warranty, expressed or implied. <br />Responsive ■ Resourceful ■ Reliable 18 <br />
