Nonpoint Source Monitoring: TechNOTES

  • Program Overview
  • NNPSMP TechNOTES
  • Volunteer Monitoring
  • Additional Resources

Through the National Nonpoint Source Monitoring Program (NNPSMP), states monitor and evaluate a subset of watershed projects funded by the Clean Water Act Section 319 Nonpoint Source Control Program. The program has two major objectives:

  1. To scientifically evaluate the effectiveness of watershed technologies designed to control nonpoint source pollution
  2. To improve our understanding of nonpoint source pollution
NNPSMP TechNOTES is a series of publications that EPA  published between 2005 and 2014 that describes this unique research and monitoring effort. TechNOTES offer:
  • guidance on data collection, 
  • implementation of pollution control technologies and monitoring design, 
  • case studies that illustrate principles in action.
