Environmental Services in Marion County, OR

Long-term agricultural use in the Willamette Valley commonly involves on-site fuel storage for equipment, pesticide and herbicide application, and sometimes on-site chemical storage structures. A Phase I ESA will identify recognized environmental conditions tied to those activities. If the Phase I flags credible concerns, targeted Phase II soil sampling — following ASTM E1903 protocols — can characterize actual soil conditions before you assume liability at closing.

Extended wet seasons in the Willamette Valley can make direct-push boring and monitoring well installation difficult on sites with poor surface drainage or weight-restricted access routes. We recommend scheduling Phase II fieldwork between May and September where the project timeline allows. For projects that cannot wait, we coordinate equipment selection and access planning through our Seattle dispatch hub to minimize weather-related delays.

Oregon DEQ administers the state's voluntary cleanup and leaking underground storage tank programs, and confirmed contamination above applicable cleanup levels typically triggers notification and, depending on severity, formal cleanup plan requirements. Our Phase II reports are structured to document findings in a format that supports DEQ submittals, though regulatory coordination and remediation design fall outside our environmental assessment scope and should involve a licensed remediation consultant.

Field work in Marion County is dispatched through the Seattle, WA regional hub, about 187 miles away. Laboratory testing is performed in Sugar Land, TX under chain of custody, or in a mobile laboratory mobilized to large Marion County projects.

Field sampling and testing in Marion County are performed by our ACI- and NICET-certified technicians. Environmental engineering and professional services are delivered with professionals licensed in Oregon, coordinated under one proposal.
