Water Quality
ERG provides scientifically sound and realistic approaches for improving the nation’s waters. We offer clients in-depth knowledge about waste streams generated by a wide range of sources. Our engineers and chemists also conduct thorough data evaluations, including targeted field sampling activities, to evaluate the effectiveness of management practices and technology options to meet changing regulatory requirements. Our environmental assessors, biologists, and modelers quantify environmental impacts and benefits associated with these approaches to help identify cost-effective solutions. We also lend our expertise to helping clients meet new water quality challenges and priorities, such as emerging contaminants and climate change impacts.
