Surban did exactly what I told him to do and a good job at <br /> it too..Unfortunately, at the time I didn't open ALL of the well heads but told him to repairl all the wells. HE <br /> did...but some were NOT wells.. <br /> There are some few things needing your attention before I sign this off... <br /> please have your people address/repair the following items. When they tell you they are completed, get in <br /> touch with me and I'll schedule a re-inspection. <br /> 1- MW-12 needs grout INSIDE traffic box lowered. Grout is AT the top of the PVC casing and they are both <br /> are too high in the traffic box (touching the bottom of the lid) and not allowing proper locking/securing of the <br /> well head. <br /> 2- there's a -14' deep by 10" diameter steel casing inside a traffic box located inbetween the center and <br /> east UST. This 10"-steel casing APPEARS to be a 'conductor casing' placed inbetween the USTs at UST <br /> installation time for future confirmation soil sampling/drilling AFTER the site completes its remediation and <br /> qualifies for No Further Action. My notes indicate that I advised these could be installed so drilling <br /> BETWEEN USTs later would not be so dangerous. Unfortunately, this casing is FULL of water with a slight <br /> sheen (petro?)on the surface. Allowing liquid (contamination) to migrate from the surface to 14' bgs is <br /> unacceptable. This site does NOT need further contamination/sources. I'm confident there is a cement <br /> grout bottom (at 14' bgs) preventing MOST of the liquid migrating into the soil, but I'm not sure how <br /> impenetrable it is. What I want is this well head/lid to be WATERTIGHT...I will accept a silicone seal being <br /> applied to the inside of the lid, AFTER ALL the water is pumped out and containerized. But if you have <br /> other thoughts on how to seal it, fine...What I want is NO water to enter this casing, as the final result. <br /> 3-1 recommended that this 'conductor casing' box, as well as a 'sewer' cleanout box (that has a Monitoring <br /> well box and lid) be sealed with unique bolt/screws so that normal monitoring and sampling techs DON'T <br /> have the correct tool to open there—just a suggestion since these boxes appear to be wells, but aren't <br /> really... <br /> let me know. <br /> -----Original Message----- <br /> From: Network Administrator [PHS] <br /> 3/22/2006 <br />
