Delaware River Basin Interactive Map

On July 31, 2018, the Environment America Research & Policy Center unveiled an interactive map of the Delaware River watershed.  The map allows journalists, policymakers, and citizens to pinpoint pollution sources and other threats to this important water source for drinking, wildlife and recreation.

The map was created using >5,000 data points from more than a dozen sources to major pollution threats in the basin, including:

  1. runoff from agriculture and impervious surfaces;
  2. 660+ industrial sources;
  3. 250+ sewage treatment plants; and
  4. fossil fuel infrastructure such as pipelines, abandoned coal mines, and refineries.
