Third-Party Optimization Reviews, Nationwide

HGL’s third-party remedial optimization reviews recommend strategies to improve efficiency and effectiveness of remedial actions for sites under both RCRA and CERCLA frameworks. Through contracts with EPA and other federal agencies, HGL has worked on over 100 CERCLA/Superfund sites to optimize remedial actions to reduce energy use, time to cleanup, and cost. Optimization strategies have included reducing monitoring frequency while improving data analysis and reporting, reducing volumes of groundwater extracted to maximize contaminant removal while minimizing energy usage, and recommending alternative remedies at sites where selected remedies are underperforming. Optimization reviews have provided technical information to terminate active remedies and transition to passive remedies, resulting in significant resource and cost savings. Current projects include evaluating remedies for sensitivity to projected climate change impacts.
