Opportunities to protect drinking water sources and advance watershed goals through the Clean Water Act

We live in times of both declining public agency resources and increasing complexity of environmental and public health problems, like the increasing occurrence, intensity, and duration of harmful algal blooms and precursors to disinfection by-products in drinking water. These and other problems are compounded by population growth, climate extremes, and excess water in some places as well as insufficient water in others.
Complex times demand creative and thoughtful approaches to challenges. It is critical that we find innovative solutions that leverage expertise, resources, efficiencies, and authorities to achieve our Nation’s water quality and source water protection goals.

As part of a State-U.S. Environmental Protection Agency (EPA) collaboration initiative, a workgroup was formed to identify opportunities to coordinate among clean water and drinking water programs. This workgroup recognizes that many difficult issues cross program boundaries, and thus a coordinated approach has the potential to make greater headway nationally. In developing the product that follows, the workgroup also drew on the experiences of states and EPA practitioners managing these programs.

This Toolkit is a result of state and EPA collaboration. It could not have been developed without the time, effort and dedication of those who contributed to it and particularly the expertise of the state and EPA regional participants who are implementing the practices in this report.

This initiative and Toolkit invite a more holistic and coordinated planning and funding approach between the clean water and drinking water programs, and with other public and private partners at the federal, state, and local levels, including water and wastewater utilities. The opportunities outlined in this Toolkit do not reflect all possible environmental authorities that may work together to protect drinking water; it is beyond the scope of this document to acknowledge all threats to, and challenges involved in, protecting drinking water. Instead, the suggestions below describe the fundamental steps toward protective actions that may catalyze broader collaboration among a diversity of programs and entities.

It is important to note that this Toolkit does not impose legally binding requirements on EPA, states, tribes, or the regulated community, nor does it confer legal rights or impose legal obligations on any member of the public. This Toolkit does not constitute a regulation, nor does it change or substitute for any Clean Water Act or Safe Drinking Water Act1 provision or EPA regulations. Rather, this Toolkit is designed to support discussion, institutional change, and advance water quality goals and the protection of drinking water sources of public water systems (PWSs)2, also known as source water protection.
