Polluted Runoff: Nonpoint Source (NPS) Pollution

Handbook for Developing Watershed Plans to Restore and Protect Our Waters

This handbook helps communities, watershed organizations, and environmental agencies develop and implement watershed plans to meet water quality standards and protect water resources, and should be particularly useful to organizations that work to restore impaired or threatened waters.

This handbook supplements existing watershed planning guides that have already been developed by agencies, universities and other nonprofit organizations. The handbook is generally more specific than other guides with respect to guidance on:
  • quantifying existing pollutant loads,
  • developing estimates of the load reductions required to meet water quality standards,
  • developing effective management measures, and
  • tracking progress once the plan is implemented.
