Cleanup Planning & Implementation


Where remedial action is necessary, EES evaluates mitigation strategies and develops cost-effective alternatives that are consistent with our clients’ goals and land use plans.

Following remedy selection, we design, deploy, and operate practical cleanup programs in the Pacific Northwest.

EES has hands-on practical experience using a range of remedial technologies that have been successfully implemented over a variety of settings, regulatory demands, and timelines.
