Contaminated Soil Cleanup

The DEQ requires USTs to be decommissioned when contamination has been detected from a leaking tank, removing the risk of further pollution.  Following DEQ protocols and standards, EcoTech works with property owners to find the best fit for their clean-up by reducing costs, working within scheduling deadlines and minimizing the disturbance to the property.

When an underground storage tank has had soil samples taken and laboratory analysis has determined the tank has or is currently leaking, the DEQ requires that the site be remediated.  The clean-up of the leaking site is determined by the levels of the contamination and the risk it poses to human health and the environment.

When a tank has leaked above 50 PPM, the contractor will need to report the leak to the Oregon Department of Environmental Quality (DEQ) within 24 hours of discovery.    Once the leak has been reported, the DEQ will send the owner of the tank a letter with information regarding regulations, report requirements, due dates and cost recovery.
