We certainly hope that remediation can begin soon <br /> Judie Kindle and Janet Roberts for Mabel Keir <br /> ----- Original Message----- <br /> From: Margaret Lagorio [EHj <br /> To: .rajak ; acolayite@od_v eo nv.com <br /> Cc: Vicki McCartney[EHj ; Nuel Henderson [EH] <br /> Sent: Wednesday, September 23, 2009 6:22 PM <br /> Subject: RE: Lopez Property <br /> Janet&Judy, <br /> The work plan prepared by AG is based on our letter to you dated April 2, 2009, in which we recommended a <br /> monitoring well be placed east o sourthest of B-6, a boring that was completed in September 2008, where <br /> a water sample collected at 63 66 feet had 14 parts per billion (ppb)of 1,2-DCA. That boring was on the <br /> eastern border of your property Since contamination has to be defined, the investigation has to be to the east <br /> and that means the City right of way or private property. <br /> Consultants prefer private property for safety reasons (no traffic)during installation and sampling and we agree <br /> with that reasoning. Most property owner don't allow access. Unless we have data from right next to their <br /> property that shows there is contamination on their property, we don't have reason to insist on their <br /> cooperation. So in this case A E will probably have to put the well on the City right of way. <br /> I don't know the history of the p ivate property, but generally there should not be contamination on the property. <br /> Data from the soil and groundwater obtained from the new well will be limited to those contaminants on your <br /> property. We hope the well will be clean and can be used to show the contaminant plume is defined and <br /> perhaps if needed can be used in any groundwater modeling that may be required. <br /> All wells are constructed to kee out surface contaminants so this should not be a concern. <br /> The most eastern monitoring wells on your property are MW 6 and MW 11. There have been no detections of <br /> 1,2 DCA in MW6 samples but samples from MW11 have averaged about 80 ppb of 1,2-DCA. You can see all <br /> these data points on the map in the work plan as well as the proposed well location. <br /> I hope this answers your questi ns. <br /> Margaret <br /> 9/28/2009 <br />
