Plus, Don Bradshaw is giving me a <br /> site tour, as I am the new RB technical PM. <br /> mtm <br /> >>> "Mike Infurna [EH] " <MInfurna@sjcehd.com> 11/10/05 10 :55 AM >>> <br /> thanks again. . <br /> LFR sent in a boring permit application and with your recent approval, I will issue and <br /> set up the drill apt with them. Do you want to know the date or be there? It's scheduled <br /> for 'daytime' , a rarity for this site. <br /> -----Original Message----- <br /> From: Marie McCrink [mailto:mtmccrink@waterboards.ca.gov] <br /> Sent: Thursday, November 10, 2005 10:25 AM <br /> To: Mike Infurna [EH] <br /> Cc: Lucas.Goldstein@lfr.com <br /> Subject: RE: Approval for CPT / MIP Work at Lincoln Center Stockton <br /> Hi Mike, <br /> Following is a reference to an approved work plan in which the CPT procedures are <br /> described, and a description of the MIP technology to be tested. I have accepted this <br /> reference and description as the work plan procedures to be followed for the MIP test. <br /> ' Standard operation procedures are included in LFR's 'Work Plan for <br /> Environmental Investigation' dated September 26, 1996. The aforementioned <br /> work plan includes procedures for direct-push (i.e. CPT) drilling. A <br /> description of the MIP technology is given below. A final work plan will be <br /> submitted after the MIP technology is proven to be 'effective' . <br /> MIP Technology Description <br /> The Membrane Interface Probe(MIP) is advanced using a standard string of <br /> 1.25" or 1.5" rods and a direct push probing unit. Before advancing the <br /> probe, the tubing which houses the carrier gas and conductivity cable is <br /> connected to the MIP tool and is strung through the probe rod. The rods are <br /> then loaded on a rod cart or fixed tool rack for easy dispensing and <br /> storage. As the probe is driven to depth, the advancement is stopped at <br /> desired intervals (typically six inches) to gather VOC data. Conductivity <br /> logging data is gathered on a continuous basis. At the desired intervals, <br /> the permeable membrane interface on the wall of the probe is heated. Any <br /> VOCs that are exposed to the membrane are volatized and picked up by the <br /> carrier gas behind the membrane which in turn delivers the gas the Gas <br /> Chromatograph detectors at the surface, typically and ECD, PID and/or FID. A <br /> stringpot, which is mounted on the probe, senses movement of the probe and <br /> measures depth and speed. The data is stored in spreadsheet compatible <br /> format for later graphing and analysis. The Gas Chromatograph readings <br /> provide total VOC readings and are stored as well for plotting.
