Underground Tank Soil Sampling Services in Portland
Immediate Preliminary Results and Official Lab Results Within 24 Hours of a Soil Test
Soil Samples Determine if an Underground Tank Has Released Hazardous Material Into the Environment.
Soil sampling is often requested by a purchaser of a property when an underground heating oil tank is present and has not been decommissioned under the Oregon Department of Environmental Quality (ODEQ) Heating Oil Tank (HOT) Program.
ODEQ Compliance
Soil samples are taken in an effort to determine whether a tank has released heating oil to the surrounding soil. Soil sampling procedures are defined by DEQ regulations, which dictate the sample depth and location, collection method, handling, and laboratory analysis. Please keep in mind that clean soil samples do not guarantee that a tank has not leaked. The ODEQ requires that any site with a confirmed release of heating oil be reported to them within 72 hours. If heating oil release is found, we can offer several cleanup and remediation options.
