There’s a New Storymap for the NMS Watersheds Alliance!
Clean Air Council and the Naamans, Marcus Hook, Stoney Creek (NMS) Watersheds Alliance are excited to announce the launch of the new NMS Watersheds Storymap! The storymap is an ArcGIS platform that shares the history, geography, and importance of the NMS Watersheds, as well as the story of the creation of the NMS Watersheds Alliance, and the accomplishments and goals of the group.
Take a Sneak Peak!
The Naamans Creek, Marcus Hook Creek, and Stoney Creek Watersheds
Naamans Creek, Marcus Hook Creek, and Stoney Creek (NMS) are part of the Delaware River Watershed and represent the last unprotected subwatershed area in Delaware County. The NMS watersheds are situated in and around the municipalities of Marcus Hook, Trainer, Upper and Lower Chichester, and Bethel Township.
Healthy watersheds are an essential foundation for healthy communities and ecosystems. These subwatersheds are a critical and valuable part of our local communities, but are also subject to ongoing pollution and contamination from local industrial sites. Petrochemical processing plants, refineries, tank farms, and other industrial facilities can leave behind legacy contaminants that persist in local ecosystems. Stormwater runoff can carry pollutants such as oil, gasoline, heavy metals, and other toxins that degrade water quality, harm local wildlife, and even impact drinking water. If left unaddressed, these issues can lead to further harm of the watershed, including reduced biodiversity and diminished access to the natural spaces that residents depend on for physical and mental well-being.
The Creation of the NMS Watersheds Alliance
In 2024, with the support of the Clean Air Council and Marcus Hook Area Neighbors for Public Health, residents came together to develop a local watershed group to protect the NMS subwatershed areas. The NMS Watersheds Alliance is a nonpartisan group of residents committed to the protection, restoration, and conservation of the Naamans, Marcus Hook, and Stoney Creek (NMS) watersheds. The Alliance aims to encourage community stewardship and to promote connection, enjoyment, and respect of the watershed by all who live, work, play, and visit. NMS Watersheds Alliance initiatives address conservation, recreation, and water pollution issues in the watershed through outreach and education, advocacy, and stewardship.

Introducing the NMS Watersheds Storymap
To tell the unique story of the NMS and virtually bring people into the watershed, the NMS Watersheds Alliance launched the Naamans, Marcus Hook and Stoney Creek Watersheds Alliance Storymap in early 2026. The creation of this storymap provides visualization of the watershed for residents and serves as an important tool for understanding our local water resources. The storymap details the history and geography of the NMS creeks, Delaware River Watershed, and pollution threats the NMS faces.
Residents can take a virtual tour of the watershed and learn more about the NMS Watersheds Alliance’s initiatives. This includes storm drain marking workshops, tree plantings, creek clean-ups, stream salinity testing, revitalization of local parks, advocating for the mitigation of pollution in our local streams, and more! The NMS Watersheds Alliance will regularly update the storymap with new projects, initiatives, and information about our creeks and watersheds. Check out the storymap to visit the NMS Watersheds virtually and learn more!
