EPA Research in the States
EPA researchers are conducting innovative, anticipatory research and applying their expertise to a range of environmental challenges including helping states and communities make informed decisions about environmental issues they face. You can view some of that research here. EPA research supports all states. This page features select stories to highlight how EPA research benefits states.
States colored blue in the map below have stories showcased here, and gray states do not have stories featured on this page.

Research across States
- Mapping Mercury in the Western U.S.
The western United States is disproportionately impacted by mercury pollution due to historic metals mining, natural geologic processes, local emissions, and trans-pacific transportation. Scientists from ORD and Regions 8, 9, and 10 partnered with the US Geological Survey and the National Park Service to gather decades of site-specific mercury data to create a comprehensive mercury cycling model. Regional and state officials are using this model to make remediation decisions at mercury-impacted impacted sites and evaluate proposals for new mining sites.
- Need for specialized risk assessment training (completed)
“The experience and knowledge of EPA scientists were essential to the success of this important training used by state risk assessors and others to address complex challenges at contaminated sites.”
– California Department of Toxic Substances Control (State Co-chair) Claudio Sorrentino
“The ITRC risk training is more robust as a result of our partnership with EPA experts on this effort.” –
–South Dakota Department of Environment and Natural Resources (State Co-chair) John McVey
EPA ORD partnered with ITRC, a program of the Environmental Research Institute of the States, to develop specialized training for state risk assessors responsible for the cleanup of chemicals released into the environment. Based on feedback from EPA’s Risk Assessment and Training Experience (RATE) program, ORD scientists reached out to ITRC and proposed that ITRC create training modules on the harmonization of risk assessment approaches across state regulators. EPA experts provided materials developed for its RATE program for the ITRC effort. These materials provide up-to-date and comprehensive training for human health risk assessment, ranging from beginner to expert classes.
The ITRC team of approximately 75 representatives from various environmental sectors completed a comprehensive web-based training module entitled, Decision Making at Contaminated Sites: Issues and Options in Human Health Risk Assessment. ORD scientists provided expert technical support as needed along the development processes and extensive peer reviews before release of the final product. Currently, all interested risk assessors in the U.S. and around the globe have free access to this important training material. To date, more than 2,100 people have taken the online course and the associated guidance document is available to download.
- Optimizing Drinking Water Treatment Practices
Algal toxins pose a significant challenge for water treatment plants due to their unique ability to spread rapidly within a drinking water supply. ORD and Region 5 collaborated with public water utilities along Lake Erie to identify the best approaches for removing algal toxins through drinking water treatment processes. The project team provided utilities and regulators across the US with technical recommendations for reducing the spread of algal toxins by changing the water pH and the order of adding treatment ingredients.
- Providing information, technical assistance and training to small drinking water systems (ongoing)
“It's very important that we provide small water systems with timely, easy to use, and accessible tools and training to assist in operating these critical public water systems, and the webinars and one-on-one meetings are perfectly suited to meet this need.”
– Ohio EPA Director Craig Butler
EPA ORD and Office of Water, in coordination with Ohio EPA and ASDWA, began hosting a monthly webinar series in 2015 targeted for state agencies on challenges and treatment solutions for small water systems. Because they have fewer resources than larger systems, small systems face enormous challenges in consistently providing safe and reliable drinking water. The series allows EPA to provide training and foster collaboration and dissemination of information, which, in turn, will help state agencies communicate the latest scientific advancements and current guidance to their small systems. It also serves as a forum for the invaluable flow of information, providing critical insight about the problems small water systems are currently encountering in their day-to-day interactions. With that increased awareness, ORD experts can then modify their research to solve real-world problems that small systems are experiencing.
As of July 2017, the series has attracted 24,374 participants from all 50 states, tribal nations, U.S. territories and international participants, and has provided 13,651 continuing education credit certificates (supported by Ohio EPA). Presenters include representatives from state drinking water agencies to help encourage communication between the states. For the webinar series schedule, registration and past recordings, visit EPA’s website.
In addition to the webinar series, EPA hosts an annual small drinking water systems workshop in collaboration with ASDWA. This free, face-to-face workshop offers in-depth training and information for handling small drinking water systems problems and compliance challenges. It is primarily designed for state personnel responsible for drinking water regulations compliance and treatment technology permitting. The workshop typically attracts between 200-400 attendees from across the nation. The 2017 workshop was held August 22-24 in Cincinnati. Formed during the 2011 workshop, ORD also leads a small drinking water systems technical communications workgroup to focus on targeted communication efforts between EPA and the states, taking into account the different needs system operators. In addition to EPA staff, the workgroup includes state regulatory agency and small water utility representatives from 13 states. A successful lead free communications tool has been developed, and the workgroup meets on a regular basis to decide on needed topics for the webinar series and to discuss the development of new tools.
