This page features stories about primarily nonpoint source pollution-impaired water bodies, where restoration efforts have led to documented water quality improvements. To explore the stories click on the map.

Annual Success Story Recap

Success Story Recaps are developed annually and provide statistics from the collection of Stories published that year including the types of NPS impairments/pollutants addressed, the number of waterbodies restored/improved, etc. Recaps also feature several example Success Stories. These publications provide a high level overview of the cumulative results from the 40-50 Stories published each year.

About the Success Stories

Clean Water Act (CWA) Section (§) 319 nonpoint source pollution success stories highlight water bodies identified by states as being primarily nonpoint source-impaired and having achieved documented water quality improvements. Projects described on these pages have received funding from CWA §319 and/or other funding sources dedicated to solving nonpoint source (NPS) impairments. These stories also describe innovative strategies used to reduce NPS pollution, the growth of partnerships and a diversity of funding sources.

Why is EPA Developing Success Stories?

The success stories offer an opportunity for states to highlight where their restoration efforts have resulted in water quality improvements in NPS-impaired water bodies. Developing the stories also allows EPA to track the number of NPS-impaired water bodies that are partially or fully restored—which is a key measure in the effort to document how NPS restoration efforts are improving water quality on a segment basis across the nation. This measure is part of EPA's National Water Program Guidance and helps to direct states in their efforts to document results. Only partially or fully restored water bodies that are featured in stories on this Web site can be counted under this measure.

Types of Success Stories

To qualify as a success story, a water body must have been listed on the CWA §303(d) list or on the Integrated Report (IR) as Category 4 or 5 water body during the 1998/2000 listing cycle or subsequent years. Since being listed, water bodies have achieved documented water quality improvements that can be attributed to actual NPS control or restoration efforts. Success stories are separated into one of three types, depending on the type of water quality demonstrated:

Type 1. Waters that are Partially or Fully Restored

These stories feature water bodies that meet water quality standards for one or more pollutants (e.g., nutrients, sediment, mercury, etc.) and/or designated uses (e.g., drinking water supply, recreation, aquatic life support, etc.) after being previously included on the CWA §303(d) list of impaired waters.

Water bodies highlighted in these stories may be either partially or fully restored. In short, partially or fully restored water bodies must:
