EOA

What EOA does

EOA, Inc. is a multi-disciplinary environmental consulting firm founded in 1993 and headquartered in Berkeley, California, with a second office in Sunnyvale. The firm specializes in water quality stewardship, combining sound science, engineering, regulatory expertise, and GIS-based information management to serve public agencies, private businesses, and research institutions primarily in the San Francisco Bay Area and throughout California. Its six service lines cover municipal and industrial stormwater management, green stormwater infrastructure planning and design, wastewater and recycled water engineering, water quality monitoring and assessment, pollutant control and watershed management (including TMDL planning), and environmental information management.

The firm's revenue model is professional services, delivered through project-based consulting engagements and long-term program management contracts, most notably continuous roles as program manager for the Santa Clara Valley Urban Runoff Pollution Prevention Program (SCVURPPP) since 1997 and the San Mateo Countywide Water Pollution Prevention Program (SMCWPPP) since 1993. EOA has built proprietary information management tools including the SunLab Laboratory Data Management Application for the City of Sunnyvale Water Pollution Control Plant and the RMC Information Management System for BASMAA's Regional Monitoring Coalition, both compatible with State Water Resources Control Board SWAMP standards. Pricing is project-specific and not publicly disclosed.

The customer base is dominated by California public-sector entities: six county-wide clean water programs, more than 25 municipal and county clients, water and sanitary districts (EBMUD, Santa Clara Valley Water District, Las Gallinas Valley Sanitary District), one industrial client (Port of Oakland), and research institutions (NWRI, WERF, WateReuse Foundation). EOA maintains board-level influence at BASMAA and CASQA, and co-founder Adam Olivieri has co-chaired NWRI expert panels that shaped California's Direct Potable Reuse framework. Leadership includes Olivieri as Principal/Founder and Senior VP, Chris Sommers as President, and Ray Goebel as Director and VP of Operations. The firm is privately held with no disclosed funding, M&A, or external investors.

Core offering

EOA is a multi-disciplinary environmental consulting firm that delivers scientific, engineering, regulatory and public policy expertise to help public agencies, private businesses, and organizations protect, restore and enhance the water environment. The firm's core offerings span six service areas: stormwater management, green stormwater infrastructure, wastewater and recycled water, water quality monitoring and assessment, pollutant control and watershed management, and environmental information management, supported by custom-built data systems such as SunLab and the RMC IMS.

Product overview

EOA is a multi-disciplinary environmental consulting firm offering six core service areas rather than a unified software platform. Services include Stormwater Management, Green Stormwater Infrastructure, Wastewater and Recycled Water, Water Quality Monitoring and Assessment, Pollutant Control Programs and Watershed Management, and Environmental Information Management. The Environmental Information Management service includes custom data management tools such as the SunLab Laboratory Data Management Application built on Microsoft Access, and the RMC Information Management System for creek status monitoring. EOA does not offer a software product with modular architecture; rather, they provide consulting services with bespoke data management solutions tailored to individual client needs.
