. An additional groundwater sample was collected from MW-1 after <br /> purging the well, and analyzed for total petroleum hydrocarbons as <br /> motor oil (TPH MO)using EPA Method 8015 <br /> No additional analytical work was completed in accordance with the November 19, 2004 <br /> directive ENSR completed quarterly sampling separately which win be reported in the fourth <br /> quarter monitoring report <br /> VIDEO RECORDING <br /> The inner casing was video taped from top of casing (TQC) to total depth(TD) prior to and <br /> after development, as requested by the Board There appears to be some residual sealant from <br /> approximately 30 feet below ground surface (bgs) to static water level (SWL) measured at <br /> approximately 37 00 feet bgs It appears that the first attempt to swab the well was successful, <br /> however visual observations of the casting indicates a bend to the well casing inhibiting the <br /> effort to scrub the casing below the bend There also appears to be some residual sealant around <br /> ajoxnt at SWL <br /> The water column appears to be clear and free of any visible floating sealant, and the screened <br /> interval appears clear and free of any obstructions, but contains a moderate amount of organic <br /> growth adhered to the well casing <br /> REDEVELOPMENT ACTIVITIES <br /> Approximately 210 gallons of groundwater were purged from the well at a rate of seven gallons <br /> per minute Manual measurements of the SWL dunng development showed a water column draw <br /> down of approximately 5 feet from the initial SWL <br /> Purged groundwater was pumped unto 55-gallon drums and stored on-site prior to disposal The <br /> purged water will be disposed of as a non-hazardous waste by a certified waste hauler after the <br /> lab data are received <br /> GROUNDWATER SAMPLING <br /> Groundwater samples were collected from well MW-1 on January 4, 2005, prior to disturbing the <br /> wells water column and after purging activities The samples were collected using a disposable <br /> bailer and placed in appropriate laboratory prepared containers, using proper sample handling and <br /> char of custody (COC) protocol The sample containers were properly labeled, stored in a <br /> cooler at 4°C or less, and transported to SunStar Laboratories, a state certified laboratory under <br /> completed COC documentation <br /> An ENSR representative was also onsite to observe redevelopment and sampling activities Split <br /> samples were not collected during this event <br />
