Page 5 of 6 <br /> Subject: RE: TOC-CP # 5449 <br /> story of my life Ben.. <br /> I neglected to tell you of my vacation plans from June 15 to June 30.... <br /> looks like you may just have to do it w/o me and I'll come by some time <br /> in July to check out the boxes/wells. <br /> anticipate any grouting need please by advising your techs to bring a <br /> bag or two of cement, a bucket and some sort of stirring/mixing device <br /> with them to this FIRST sampling event. It's not uncommon to have the <br /> grout drop out of the bottom of the traffic box after installation. This is <br /> an unacceptable condition to which more grout must be added. It's one <br /> of the things I look for after new wells are installed. <br /> the rule I go by is to have the hardened grout/bentonite seal level inside <br /> the 'lower' half of the traffic box skirt and the PVC casing up in the <br /> 'upper' half of the traffic box. this is for wells NOT scheduled to be <br /> manifolded/added to some remediation trunk line. wells scheduled for <br /> connection later on must at least have an impermeable seal installed <br /> INSIDE the traffic box with the purpose of inhibiting any liquid that <br /> enters the traffic box from migrating down the borehole. <br /> thanks in advance for your consideration in this matter. <br /> Mike Infurna. <br /> From: Ben Chevlen [maiIto:ben.chevlen@atcassociates.com] <br /> Sent: Thursday, June 09, 2011 2:21 PM <br /> To: Mike Infurna [EH] <br /> Subject: RE: TOC-CP # 5449 <br /> Mike—The well development activities are currently scheduled to be <br /> performed on June 16 and 17 (next Thursday and Friday). The wells will likely <br /> be sampled during the week of 6/20; however, a final date has not yet been <br /> set.
