Nonpoint Source Pollution: Impacts
[EPA] 2003 Dec 3. WATERS: Watershed Assessment, Tracking & Environmental Results< http://www.epa.gov/waters/>
WATERS is an information system that connects several surface water quality databases from the EPA’s Office of Water (OW) into a large framework for a more comprehensive look at the health of watersheds. This website can be used to answer questions such as: “Can I eat the fish in my watershed? Is it safe to swim the water?” This site also provides a download for EnviroMapper for Water, an interactive web-based GIS tool that allows you to customize maps of and display water quality information for waterbodies near you.

This document provides an overview of nonpoint source pollution, explains how nonpoint phosphorus and nitrogen can affect waterbodies through eutrophication, identifies the major sources of nonpoint phosphorus and nitrogen pollution, and offers suggestions on ways to reduce nonpoint source pollution. It is published in Issues in Ecology through the Ecological Society of America and is a required module in the EPA’s Watershed Academy Certificate Program.
