As a leader in resolving complex environmental issues for over three decades, EOA is a small environmental engineering consulting firm located in the San Francisco Bay Area. We specialize in assisting the public and private sector clients on water quality management.

Our exceptional technical staff of engineers, scientists and planners, most with advance technical degrees and over 10 years of consulting experience, have led in the development and implementation of award-winning water quality control and monitoring and assessment programs. We have also successfully conducted numerous studies and policy initiatives designed to protect and restore fish and wildlife in California.

With a focus on public agency assistance, we’ve created and assisted cities and counties in managing the impacts of stormwater and wastewater on local creeks, rivers, estuaries and the Pacific Ocean through innovative techniques such as green stormwater infrastructure. We’ve also provided invaluable services to resource managers by conducting risk assessments and identifying pollutant control programs and watershed management actions needed to evaluate practical solutions to challenging water quality problems. Data and information collected through these efforts is easily accessible to our clients through our advance information management systems.
