Bowen Property <br /> 26783 North Cherokee Lane <br /> Lodi,California 95632 <br /> Assessor's Parcel Number: 005-110-13 <br /> SR0078905 <br /> SUBJECT: Response to EHD Review Document <br /> Reference is made to the attached EHD Review Document dated February 8,2019. I have been asked to <br /> respond to Item 2 of this document. The first sentence of Item 2 states"The data indicates the onsite water <br /> well has elevated level of nitrate and may not be a suitable source for the potable water supply for new <br /> development." Attached, is Page 5 and Table 3 from my Studies summarizing the Well Water Analysis. <br /> As noted,the Analyte in column one is for"Nitrate as Nitrate,"not"Nitrate as Nitrogen." The <br /> concentration found was 15 ppm in column two. The third column indicates the Maximum Contaminant <br /> Level(MCL)to be 45 ppm. <br /> When nitrate test results are issued as"nitrate as nitrate,"the MCL is 45 ppm(actually 44.43 ppm). When <br /> nitrate test results are issued as"nitrate as nitrogen,"the MCL is 10 ppm. As noted on the A&L <br /> Laboratories Water Analysis Report,the Analyte tested was for Nitrate,not Nitrate-Nitrogen. Therefore, <br /> the water test results are actually one-third of the MCL for nitrate. This nitrate test result was confirmed <br /> with Mr.Robert Butterfield, owner of A&L Laboratories West. <br /> Respectfully submitted, 4tofessio� <br /> a,��aon D ChesdBf�` <br /> CHESNEY CONSULTING q <br /> No.75479 <br /> Don Cheney, PE `Pfafe C;vi1 tr`� <br /> Registered Civil Eng' er#C75479 of Calito <br /> Attachments: <br /> 1.
