Water Resources and Quality

Water is essential to every American community, from drinking water supplies to agriculture and industry. The federal government works across multiple agencies to manage the nation’s water resources, protect water quality, and ensure reliable supplies for families, farms, and businesses. Understanding how federal, state, and local governments coordinate on water management helps navigate infrastructure projects and environmental protections.

Water Quality and Safety

The Environmental Protection Agency sets and enforces national standards for water quality and treatment, while states implement programs like Total Maximum Daily Load to control pollution in surface waters.

Managing Water Supply and Resources

Federal efforts focus on preserving water sources, delivering infrastructure, and meeting health standards through agencies like USGS, Interior, and Commerce. These support forecasts, desalination, and recycling, including major projects like California’s Central Valley Project balancing agriculture, supplies, and ecosystems. Disaster management for floods and droughts addresses climate impacts.

Broader Water Governance

Water resources include coastal and ocean areas under federal authority. See Understanding U.S. Maritime Zones: Territorial Waters vs. Exclusive Economic Zones for U.S. governance of these waters. Watershed organizations and governments share planning to meet public health and environmental needs.
