Frankly speaking, it just doesn't make a lot of sense to me to <br /> increase the costs by literally thousands of dollars to end up with a grout <br /> seal that has no guarantee to be as good as the seal that we already have <br /> and know is working.And if you feel that this is something that warrants <br /> the approval of the director, please let me know what additional steps <br /> that would require. <br /> Thank you for working this out with me in advance. I, like you, would rather deal <br /> as many issues as possible while sitting nice and cozy in my office than in the cold <br /> January rain that I'm sure will start as soon we break ground. Please give me a <br /> call if you have any questions. <br /> Cheers and have a good weekend, <br /> 0 40thlogo -Josh Ewert I Senior Staff Geologist <br /> Geocon Consultants, Inc. <br /> 3160 Gold Valley Drive Suite 800, Rancho Cordova, CA <br /> 95742 <br /> Tel 916.852.9118 Fax 916.852.9132 <br /> www.geoconinc.com <br /> From: Mike Infurna [EH] [mailto:MInfumaCalsjcehd.coml <br /> Sent: Thursday, October 13, 20113:21 PM <br /> To: Evans, Brenda; Jim Barton <br /> Cc: McKenna, Stephanie; BORGIOTTI, SERGIO I; ngleason(o)DowneyBrand.com; <br /> iayallenl(&att.net; Jim Brake; Josh Ewert <br /> Subject: RE: 5400 and 5606 Pacific Avenue, Stockton -Well Destruction <br /> Information <br /> Ladies and Gentlemen, <br /> I have evaluated the proposal/list of wells and destruction <br /> methods submitted to me and have the following changes <br /> to bring to your attention. <br /> I looked for current and historical soil, water, or vapor <br /> laboratory data for each well that was listed to be <br /> destroyed by pressure grouting. As I have stated before, <br /> the SJCEHD has a Well Standard (Ordinance) that <br /> provides for acceptable well destruction methods. As <br /> stated in this Ordinance, "if the well construction is <br /> unknown and/or is located in an area of known or <br /> suspected pollution or contamination, the well shall be <br /> destroyed by removing all material within the original <br /> borehole (including the well casing, screen, filter pack and <br /> annular seal)".
