Michael Kith [EH] <br /> From: Abby Racco <abby@logelodi.com> <br /> Sent: Tuesday, March 05, 2019 11:57 AM <br /> To: Michael Kith [EH]; Brittany Farris; Dave Welch <br /> Subject: Re: Farris NLS <br /> Michael, <br /> We do use the same numbers in the end, but we have added additional discussion to explain the selection of the <br /> percolating recharge water value. We have taken into account the latest Eastern San Joaquin County <br /> groundwater subbasin report, and evaluated the choices of recharge water value against the regional recharge <br /> value from that report. The discussion provides a local justification for the rainfall reduction method selected. <br /> Based on the sources discussed in the addendum, we feel confident that the 75% of rainfall method comes <br /> closer to an accurate value for recharge than the precipitation minus evapotranspiration method. Based on the <br /> subbasin report and Dave's discussions with Tim O'Brien at the Water Board several years ago, we are not <br /> comfortable at this time using the evapotranspiration method because it underestimates recharge. As a licensed <br /> professional, Dave would need a technical explanation to justify EHD's directing him to use the <br /> evapotranspiration method. <br /> We are happy to come meet with you and Linda in person to discuss the nitrate loading calculation if that would <br /> be helpful. <br /> Thank you, <br /> Abby <br /> Abby Racco <br /> Live Oak GeoEnvironmental <br /> (209) 369-0375 <br /> (209) 365-3222 cell <br /> www.logelodi.com <br /> On 3/5/19 11:07 AM, Michael Kith [EH] wrote: <br /> It is the same the one you have submitted. <br /> Michael Kith, REHS <br /> Program Coordinator <br /> San Joaquin County Environmental Health Department <br /> 1868 E.
