Soil Sampling

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.

Environmental Sampling

Testing Soil, Groundwater, Soil Gas, and Ambient Air for the Presence of Contaminations that may Impact Our Human Health and/or Our Environment

From residential Heating Oil Tanks (HOT) buried next to your homes to Gasoline Stations and Auto Repair Shops, Dry Cleaners, Commercial Facilities, Industrial Facilities and more, Environmental Works (EW) is ready to partner with you to determine if there is Environmental Issue on your property.

Examples of Environmental Issue Causes could include:

  • Leaks from a Buried Heating Oil Tank
