Problems/Comments
Crude oil-contaminated soil was detected over the liner north of Tank 15 on 8 October 1988. The release was estimated to involve 20 gallons of crude oil and is believed to have originated from a "mixer motor" spill. Crude-contaminated soils were only discovered above the liner, and confirmation samples were collected from beneath the liner (results unavailable). Contaminated soils were excavated, spiked with fertilizer, and landfarmed.
