Annual monitoring continues until future plans for the site are known or no Volatile <br />Organic Compounds (VOC's) are detected. <br />2. Results of the private well testing continue to be sent to the individual residences. <br /> <br />Backlround/Discussion <br />Liesch Associates, Inc. completed the yearly groundwater sampling on June 7, 2007. Samples were taken <br />at monitoring wells MW -2, and MW -3 within the dump, and the Vandenberg and Hipsag residential wells <br />located west and southeast of the dump. The Kirkeide and Brown residences, formerly located south of <br />the dump, no longer exist. MW -1 formerly located north of the dump was sealed in 2002 when a parking <br />lot for the city park was constructed in the area where the well was located. <br /> <br />FINDINGS <br />· Volatile Organic Compound (VOC) detections were at a low level in MW -2 and no VOCs <br />were detected at MW-3. 1,1,2,2-tetrachloroethylene (pC E) was identified at 1.0 parts per <br />billion (Ppb) in MW-2. The PCE level detected in MW-2 is consistent with historic low <br />PCE concentrations <br />· No VOCs were detected at the Vandenberg and Hipsag residential wells. <br />· VOC concentrations at the monitoring well locations continue to be stable. <br />· The concentrations are below current Minnesota Department of Health (MD H) Health Risk <br />Limits (HRLs) for drinking water. <br /> <br />Financial Impact <br />Annual cost of monitoring is $500.00, which is paid for out of the Landfill Abatement fund. <br /> <br />Attachments <br />-June 2007 Groundwater Monitoring Results for the Old City Dump; Tom C.
