I do not believe that the presence of phosphorus in this well <br /> is indicative of anything other than the leaching and diffusion of this class of material from fertilizers <br /> that have certainly been used extensively in this area. This phosphorus level in this well was docu- <br /> mented by EPA Procedure 363.2. <br /> Results obtained under EPA Methods 8260B were developed using a combination gas chromatogra- <br /> phy and quadruple mass spectrometry. Please note that every organic chemical that can be detected <br /> by this procedure showed"ND"-'non detectable—results. It is my judgment that no further action <br /> should be required on this well or the surrounding surface and sub-surface areas. <br /> Should you have any questions on any of the data,or any of the conclusions of this Supplemental <br /> Report,please do not hesitate to contact me. Thank you very much for permitting me to be of service <br /> to you in this matter. <br /> Sincerely, <br /> <���1.� UVJ ✓ {r�L�4'�r�.l�_ <br /> Edward W.Finucane,PE,QEP,CSP,CIH <br /> EWF:gwf <br /> xc: Alan Biedermann,R.E.H.S. <br /> San Joaquin County Environmental Health Department <br /> Matt Browne, C.C.E.
