Item Techniques for Tracking, Evaluating, and Reporting the Implementation of Nonpoint Source Control Measures: I. Agriculture(United States Environmental Protection Agency, 1997-09) United States Environmental Protection Agency Office of WaterThis guidance is intended to assist state, regional, and local environmental professionals in tracking the implementation of best management practices (BMPs) used to control agricultural nonpoint source pollution. Information is provided on methods for selecting sites for evaluation, sample size estimation, sampling, and results evaluation and presentation. The focus of the guidance is on the statistical approaches needed to properly collect and analyze data that are accurate and defensible. A properly designed BMP implementation monitoring program can save both time and money. For example, there are over 37,000 farms in the state of Virginia. To determine the status of BMP implementation on each of those farms would easily exceed most budgets and thus statistical sampling of sites is needed. This document provides guidance for sampling representative farms to yield summary statistics at a fraction of the cost of a comprehensive inventory.
