Recent Projects

K&S has performed numerous Phase 1 Environmental Site Assessments throughout Oregon & Washington for West Coast Mobile Home Parks, Inc. Additional work included performing soil sampling and decommissioning an underground storage tank by removal. We also excavated contaminated soil, performed sub slab soil-gas sampling in a basement, and completed a risk- based evaluation for the remaining contamination at the site in order to obtain a “No Further Action” determination and regulatory closure from the DEQ.

A local residence had a heating oil tank located beneath the edge of their porch, extending 8 feet laterally beneath the porch and house. K&S hand-excavated 4 ½ feet down to reach the end of the tank. We entered the tank, removed all sludge, and completely cleaned the tank interior. Once cleaned, K&S cut holes in the bottom of each end of the tank and collected soil samples. Since analytical results did not detect petroleum contamination, we returned to the site, properly filled the tank with an inert material, and backfilled the excavation to grade.

At several mobile home parks located in the Northwest, K&S performed Phase 1 Environmental Site Assessments. Additional work included performing soil samples and decommissioning an underground storage tank by removal. We also excavated contaminated soil, performed soil-gas sampling in basements, and completed a risk-based evaluation for remaining contamination at the site in order to obtain a “No Further Action Required” determination and regulatory closure from the DEQ.

Working with Lincoln County Road Department, we manage various environmental and compliance issues for them. Our assistance includes project management, removing UST’s, performing subsurface investigations/drilling, collecting required soil and groundwater samples, risk-based evaluations, Phase 1 Environmental Site Assessment, DEQ correspondence/reporting, and the installation and quarterly compliance sampling of monitoring wells.

For one of our residential projects, a heating oil tank was located in the backyard of a house. To minimize damage to the landscaped yard, we lined the access pathway with plywood. Using a rubber track excavator, we excavated to the top of the tank. Once we had access to the tank, it was cut open and thoroughly cleaned before being removed and hauled to a local recycler. Approximately 10 tons of petroleum-contaminated soil was excavated and disposed of properly. K&S collected confirmation soil samples to ensure that sufficient contaminated soil was removed to meet DEQ’s Soil Matrix cleanup standards. After positive confirmation, the excavation was backfilled to grade and the site was restored.
