ADEC funded the installation of two additional GW MWs in December, 2002. First sampling of these wells resulted in non detects. Cook's consultant completed the yearly GW monitoring event for 2002. Also performed a domestic water well drawdown test in the effort to determine if pumping of the domestic well would draw down the water table 35 feet away at MW GE-8. No drawdown was detected after 6 hours of pumping. |

Document, Report, or Work plan Review - other |
ADEC received and reviewed the September 2005 MWH July 2005 Annual Monitoring Event Report. GW concentrations were down in 3 MWs, the same in 2 MWs, and up in 1 MW. One of the injection wells (REC-2) in the air stripping GW recirculation treatment system plugged up. Former vapor stripping circulation well VSC-1 was converted to an injection well (newly named REC-3). The groundwater treatment system has nonfunctional due to power outages. ADEC has requested that an auto-dialer and a run hour meter be installed on the system to notify MWH of system shutdowns and to record the number of hours the system operates. These items are to be installed in September, 2005. |

Using Figure 1 from a Drilling and Monitoring Well Installation Report Cook's Service Station, from Kent & Sullivan, dated July 30, 1999, in conjunction with TopoZone Pro and the KPB Parcel Lookup, entered the coordinates for this site. Metadata includes No Topo Basemap, TopoZone Pro Street Maps, Black and White Aerial Photo, on a Medium Size Map, View Scale 1:10,000, Coordinate Datum NAD83. High degree of confidence in accuracy of location. |

Site Visit |
Inspected the site in July 2006, due to reports of a damaged GW MW security casing. Observed that MW KS-3 was exposed due to separation of security casing cover from the security casing. Reported this finding to Asst. A.G. who is in settlement negotiations with the Cook's and their counsel. |

Reviewed the June 2007 SLR Decommissioning of Treatment System and Wells Groundwater Sampling Report. SLR Alaska implemented the decommissioning of the onsite GW treatment system and the decommissioning of 11 off site GW monitoring wells. SLR also sampled 5 remaining GW monitoring wells for purposes of long-term GW quality monitoring. GW quality data were similar to the 2005 GW monitoring data. GW trend is decreasing contaminant concentrations. |
