National Aquatic Resource Surveys
The U.S. Environmental Protection Agency, states, and tribes are conducting a series of national aquatic resource surveys. Often referred to as probability-based surveys, these studies report on core indicators of water condition using standardized field and lab methods. The surveys include a national quality assurance program and are designed to yield unbiased, statistically-representative estimates of the condition of the whole water resource (such as rivers and streams, lakes, ponds, and reservoirs, wetlands, etc).
