1 � <br /> ranex <br />' Quality Control Vironex utilizes a response test* prior to each MIP boring A solution containing water, <br /> Trichloroethene & Toluene are mixed and transferred into a galvanized test pipe The MIP is <br /> then lowered into the test pipe for 45 seconds and then extracted The trip time' is then noted <br />' and entered into the SC4000 MIP computer <br />' *Response Test-A test that ensures that the MIP system is working correctly <br /> **Tnp Time-Time it takes for the standard to enter the MIP probe at the probe membrane till the time a significant <br /> response is noticed on the 5C 4000 Computer <br />' MIP Components -Geoprobe 6600 <br /> Used - FC 4000 MIP Computer <br />' - Flow Control Box <br /> - HP Gas Chromatograph <br /> - ECD (Electron Capture Detector) <br /> PID (Photo Ionization Detector) <br /> - FID (Flame Ionization Detector) <br /> 150' Trunk Line <br /> - 1 5" MIP Probe <br />' - 1 5" Drive Rods <br /> Soil Confirmation Confirmation samples were collected and released to Shaw E&I for analysis <br />' The MIP system will detect most VOC's (Volatile Organic Compounds) which have the <br /> Qualitative Analysis capability of migrating through the membrane The ECD (Electron Capture Detector) will <br /> (identification) typically detect chlorinated compounds The PID will typically detect aromatic and double <br />' bonded compounds, typical of gasoline components and some solvents At high <br /> concentrations the ECD, PID and FID may detect other compounds not normally associated <br /> with the detector Physical sod samples which are prepared by EPA Method 5035, and <br />' analyzed by EPA Method 8260, may be semi correlated with the MIP responses The MIP <br /> responses are semi-correlated with most detected compounds, even those which are not <br /> reported nor detected by EPA Method 8260 <br />' Lithology The conductivity of soils is different for each type of media Finer grained sediments, such as <br /> silts or clays,will have a higher EC signal While coarser grained sediments, sands and gravel, <br /> will have a lower EC signal Lithology should be correlated with a physical sod sample <br />' Frank Stolfl <br /> National Director of MIP Services <br />' 4of32 <br /> 1225 East McFadden Avenue a Santa Ana a CA 92705 • USA• Phone 714-647-6290 * Fax 714-647-6291 <br /> San Francisco CA Los Angeles Washington DC Fredericksburg VA Raleigh NC Wilmington DE <br />
