Cleanup Complete
The former gas station service bay floor drains and sump discharged to a drywell. The drywell was filled with sediment and sludge. Soil samples from the drywell showed that diesel and heavy-oil contamination required cleanup. About 1.82 tons of sediment and sludge were removed.
Soil around the drywell was excavated to 2 to 4 feet around the outsides of the drywell wall and about 5 feet below the base. Five confirmation soil samples were taken from all sides and under the drywell. Soil sample results show diesel and heavy-oil contamination to be below safe levels.
Ecology completed an initial investigation in April 2024 and decided no further cleanup was required in May.
