Focus and Agenda

The 21st Annual EPA Drinking Water Workshop, which took place on September 17-19, 2024 in Cincinnati, Ohio, was hosted by EPA's Office of Research and Development and Office of Water in partnership with the Association of State Drinking Water Administrators (ASDWA).
The workshop focus was on PFAS and lead (Pb) topics, and was designed for EPA and Tribal, state, and territory government agencies responsible for drinking water regulations compliance and treatment technologies permitting. It provided current technical and regulatory information, resources, and training needed to help in building systems capacity and sustainability and with providing equitable access to drinking water. The focus on specific topics and government agencies allowed EPA and ASDWA to optimize networking, increase engagement, and promote a shared learning experience.
The workshop included technical information sessions, interactive training sessions, breakout group roundtable discussions, topical deep dive and posters session, regional networking session, and other networking opportunities.
Technical session post-workshop webinars
For those unable to attend the workshop, opportunities to benefit from the technical session presentations were provided in a virtual setting as part of the Small Drinking Water Systems Webinar Series. Extended PFAS webinars were held on September 24 and October 29 in 2024 and extended Pb talks were held on December 3, 2024, and April 29, 2025.

Workshop History

To provide timely information that support the efforts of state and local officials to assist their small systems, EPA’s Office of Research and Development (ORD) and Office of Water (OW), in partnership with the Association of State Drinking Water Administrators (ASDWA), have hosted an in-person annual drinking water workshop in the Cincinnati, Ohio metropolitan area for over 20 years.
The workshop is held in the Cincinnati area because of the large number of staff from EPA’ s ORD and OW that work at EPA’s Andrew W. Breidenbach Environmental Research Center (AWBERC) and lead or support drinking water-focused research, technical assistance, and regulatory efforts. EPA’s AWBERC, located near the Cincinnati Innovation District, is the Agency’s second largest research and development facility and is internationally recognized for water research, bioremediation, and pollution prevention. Because of this, holding the workshop in the Cincinnati area is the most cost-effective location for the Agency and provides workshop participants an opportunity to benefit from engagement and training opportunities with EPA drinking water experts.
When the first workshop was held in 2004, it was by invitation only and designed as an educational opportunity for state staff working with small communities to install arsenic treatment technologies. In 2008, at the encouragement of state agencies, the workshop was opened to the public and expanded to include small drinking water system distribution, water quality, source water, treatment, and operations topics.
As the workshop grew over the years, attendance rose from the 100s to up to the 600s, and some of the sessions were broadcast live as webinars for those unable to attend. In 2020 and 2021, the workshop was held entirely in a virtual platform due to travel restrictions related to the pandemic and had upwards of 3,000 attendees. In 2023, we celebrated the workshop’s 20-year anniversary with close to 400 in-person participants from federal, Tribal, state, territory, and local governments; international governments; utilities; non-government organizations; consulting and technical assistance services; academia; private industry; and others
About Small Systems

There are 145,720 active public water systems in the United States (including territories). Of these, 95% (138,923) are considered small systems under the Safe Drinking Water Act, meaning they serve 10,000 or fewer people.
- Small systems serving 500 or fewer people: 114,928
- Small systems serving 501-3,300 people: 18,753
- Small systems serving 3,301-10,000 people: 5,242
While many of these active small systems consistently provide safe, reliable drinking water to their customers, many face a number of challenges in their ability to achieve and maintain system sustainability. Some of these small system challenges include lack of expertise to choose, operate, and maintain systems; lack of financial resources; aging infrastructure; limited options for residual disposal; and state agencies with limited resources to support the large number of small systems. EPA's research is developing tools, technologies, and approaches to help small systems lower costs and provide safe drinking water now and in the future.

Additional Resources
Webinar Series
In addition to this annual workshop, EPA also holds a free monthly webinar series. The Small Drinking Water Systems Webinar Series provides a forum for EPA to communicate directly with drinking water professionals to provide training and foster collaboration and dissemination of information. Beginning in January 2024, some webinars in the series are now being held in partnership with ASDWA.
Webinar topics vary each month and are primarily designed for Tribal, state, and territory government agencies responsible for drinking water regulations compliance and treatment technologies permitting. However, others may also benefit from the webinars, including water system operators, technical assistance providers, NGOs, local government personnel, academia, and private sector. This series will continue to provide the latest information on solutions for challenges facing small drinking water systems, but will now be more of an extension of the in-person workshop as it will include presentations that were given during the events. Webinars in this series are typically held on the last Tuesday of the month, from 2 to 3 p.m. ET.
