Installation-restoration program. Phase 2. Confirmation/quantification. Stage 1 for Kingsley Field, Oregon. Final technical report, September 1983-June619 85

A field investigation was performed at Kingsley Field, Oregon to determine if environmental contamination has resulted from past waste disposal practices in a closed landfill. Site specific activities included an electrical resistivity study to determine the presence and directional flow of groundwater, installation of monitoring wells adjacent to the landfill, and seasonal sampling of groundwater from the two landfill monitoring wells and two domestic water supply wells on nearby off-base properties. Study findings suggest that landfill leachate may be mobilizing and migrating away from the landfill through groundwater transport. However, groundwater quality remains very good in both domestic wells tested and, except for total iron, good in on-base monitoring wells. There are no contaminants yet detected in the groundwater which would threaten public or environmental health. A long-term monitoring program is recommended so as to detect changes in groundwater flow or quality.
