Nonpoint Source Monitoring: TechNOTES
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:
- To scientifically evaluate the effectiveness of watershed technologies designed to control nonpoint source pollution
- 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.
