Pollution and Water Quality
According to the United Nations, declining water quality has become a global issue of concern as human populations grow, industrial and agricultural activities expand, and climate change threatens to cause major alterations to the hydrological cycle. Resources available in this sub-theme include manuals describing water quality testing and treatment, reports and assessments of water quality from around the world, methods of maintaining water quality and managing pollution, and other resources that support enabling environments for effective water quality control.

U.S. Department of Agriculture
AGNPS is a tool for use in evaluating the effect of management decisions impacting water, sediment and chemical loadings within a watershed system.
The term "AGNPS" now refers to the system of modeling components instead of the single event AGNPS, which was discontinued in the mid-1990...Read more
A Procedure to Estimate the Response of Aquatic Systems to Changes in Phosphorous and Nitrogen Inputs
Published:
October 1, 1999U.S. Department of Agriculture
This document provides a simple assessment procedure
to estimate the responsiveness of a waterbody to
changes in the supply (loading) of phosphorus (P) and
nitrogen (N). Lakes, rivers, streams, and estuaries may
be assessed with this procedure. Few data about the
waterbody are required. The...Read more
