Nonpoint Source Monitoring Guidance


This nonpoint source monitoring and evaluation guide is written for use by both those who monitor and those who evaluate and fund monitoring proposals. For example, the federal, State, and Tribal agencies that support monitoring activities might use the guide to assess the technical merits of proposed monitoring and evaluation plans. These same agencies, university personnel, and others that carry out the monitoring and evaluation might use this guide to formulate their own monitoring plans.

The 1997 guidance focuses on monitoring to determine the effectiveness of nonpoint source controls at the watershed and practice levels. A short overview of monitoring design options is followed by detailed sections on biological monitoring, statistical data analysis methods, and quality assurance and control.
