The National Water-Quality Assessment Program is a critical component of the United States Geological Survey (USGS) Water Resources Division, which is responsible for assessing the nation's water resources and providing water quality data to support water resource management decisions, in collaboration with the National Water Quality Inventory and the USGS Water Science Centers. The program is designed to provide a comprehensive understanding of the nation's water quality, including the physical, chemical, and biological characteristics of surface water and groundwater, and to identify water quality trends and trends analysis, using data from the USGS National Water Information System and the EPA Storage and Retrieval (STORET) database. The program's findings are used to support the development of water quality standards and total maximum daily loads (TMDLs) by the Environmental Protection Agency (EPA) and state environmental agencies, such as the California Environmental Protection Agency and the New York State Department of Environmental Conservation, in accordance with the Clean Water Act and the Safe Drinking Water Act. The program also collaborates with other federal agencies, such as the National Oceanic and Atmospheric Administration (NOAA) and the United States Department of Agriculture (USDA), to assess the impacts of climate change on water resources, using data from the National Centers for Environmental Information and the USDA National Agricultural Statistics Service.

Program Overview

The National Water-Quality Assessment Program is a long-term program that was established in the 1990s to assess the quality of the nation's water resources, including rivers, lakes, wetlands, and aquifers, in collaboration with the United States Geological Survey (USGS), Environmental Protection Agency (EPA), and other federal agencies, such as the National Park Service and the United States Fish and Wildlife Service. The program involves partnerships with various stakeholders, including state governments, local governments, and non-governmental organizations (NGOs), such as the Nature Conservancy and the World Wildlife Fund, to support the development of water quality standards and total maximum daily loads (TMDLs), in accordance with the Clean Water Act and the Safe Drinking Water Act. The program's goals include assessing the physical, chemical, and biological characteristics of surface water and groundwater, identifying water quality trends and trends analysis, and providing water quality data to support water resource management decisions, using data from the USGS National Water Information System and the EPA Storage and Retrieval (STORET) database. The program also collaborates with other federal agencies, such as the National Oceanic and Atmospheric Administration (NOAA) and the United States Department of Agriculture (USDA), to assess the impacts of climate change on water resources, using data from the National Centers for Environmental Information and the USDA National Agricultural Statistics Service.

Study Design and Methods

The National Water-Quality Assessment Program uses a variety of study design and methods to assess the quality of the nation's water resources, including surface water and groundwater, in collaboration with the United States Geological Survey (USGS), Environmental Protection Agency (EPA), and other federal agencies, such as the National Institute of Environmental Health Sciences and the Centers for Disease Control and Prevention. The program uses a probabilistic sampling design to select sampling sites and monitoring stations, and collects water quality data using a variety of sampling methods, including grab sampling and continuous monitoring, using equipment from manufacturers such as Hach Company and YSI Incorporated. The program also uses laboratory analysis to measure water quality parameters, such as pH, temperature, and nutrient concentrations, using methods developed by the American Public Health Association and the American Society for Testing and Materials. The program's findings are used to support the development of water quality standards and total maximum daily loads (TMDLs) by the Environmental Protection Agency (EPA) and state environmental agencies, such as the California Environmental Protection Agency and the New York State Department of Environmental Conservation, in accordance with the Clean Water Act and the Safe Drinking Water Act.

Water Quality Trends and Findings

The National Water-Quality Assessment Program has identified several water quality trends and findings that are relevant to water resource management decisions, in collaboration with the United States Geological Survey (USGS), Environmental Protection Agency (EPA), and other federal agencies, such as the National Oceanic and Atmospheric Administration (NOAA) and the United States Department of Agriculture (USDA). The program has found that nutrient pollution is a major water quality issue in many rivers and lakes, and that climate change is affecting water quality and water availability in many parts of the country, using data from the National Centers for Environmental Information and the USDA National Agricultural Statistics Service. The program has also found that water quality is improving in some areas, such as the Great Lakes, due to pollution control efforts and restoration activities, supported by the Great Lakes Restoration Initiative and the Great Lakes Observing System. The program's findings are used to support the development of water quality standards and total maximum daily loads (TMDLs) by the Environmental Protection Agency (EPA) and state environmental agencies, such as the California Environmental Protection Agency and the New York State Department of Environmental Conservation, in accordance with the Clean Water Act and the Safe Drinking Water Act.
