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 Tech Notes is a series of publications that shares this unique research and monitoring effort. It offers guidance on data collection, implementation of pollution control technologies and monitoring design, as well as case studies that illustrate principles in action.
