| Description | The Palermo Wellfield subdrain system was monitored in November 2006 and June 2007. The subdrain lowered groundwater levels three to five feet below ground surface for the northern and central homes, but not the two southern homes. Sediment that accumulated in subdrain cleanouts CO-3 through CO-8 was removed in 2006. 2007 data indicate that some sediment is still present in cleanouts CO-4, CO-5 and CO-8. Sediment deposition or scouring does not appear to be occurring in the catch basins and lagoon. PCE (22 µg/L) and TCE (22 µg/L) concentrations continue to be highest in water samples from the southern and central portions of the subdrain. Concentrations in the treated water that discharges to the Deschutes River were below the remediation goals of 0.8 µg/L (PCE) and 2.7 µg/L (TCE). |
