Senior Environmental Engineer

I find it energizing to develop tools that help users improve their knowledge of environmental data and perform novel analyses, and I am always inspired when I see how these tools help our clients become even more effective at performing their work and solving environmental problems.


Eva Knoth (she/her/hers), a senior environmental engineer, blends her expertise in environmental compliance datasets with application development to support and inform decision-making at the U.S Environmental Protection Agency and other agencies. She began her ERG career by developing and enhancing tools for EPA’s Offices of Water and Compliance that enhanced their use of National Pollutant Discharge Elimination System wastewater data under the Clean Water Act. Her work subsequently expanded to developing new tools for EPA air, drinking water, hazardous waste, environmental justice, and right-to-know programs.

As ERG’s operations manager supporting EPA’s Enforcement and Compliance History Online website, Eva has led projects to build, enhance, and maintain dozens of ECHO searches and tools over the last ten years. These tools, including the Water Pollutant Loading Tool and NPDES Noncompliance Report, have helped increase access to and understanding of environmental data. Eva also enjoys developing and delivering trainings to help EPA and its stakeholders understand how to use ECHO applications and share knowledge of complex environmental datasets.

Eva holds a B.S. in neuroscience from the University of Rochester and an M.S. in civil engineering from Carnegie Mellon University. She enjoys hiking and kayaking in her spare time.
