Stormwater best management practices (BMPs) are gaining recognition as effective, flexible, and environmentally sound ways for controlling the quantity and improving the quality of stormwater runoff, while also adding amenity to a wide variety of development projects.
This website is designed to encourage and facilitate the integration of stormwater BMPs into development projects in your area by providing tools and resources for effective communication and implementation as well as in-depth more...

A "coastal ecosystem" includes estuaries and coastal waters and lands located at the lower end of drainage basins, where stream and river systems meet the sea and are mixed by tides. The coastal ecosystem includes saline, brackish (mixed saline and fresh) and fresh waters, as well as coastlines and the adjacent lands.

EPA and the Corps of Engineers have jointly issued a legal memorandum that interprets the June 19, 2006 Supreme Court decision in the consolidated cases Rapanos v. U.S. and Carabell v. U.S. (known as the "Rapanos" decision). The guidance is being released to Corps of Engineers and EPA field offices to ensure nationwide predictability, reliability, and consistency in identifying wetlands, streams and rivers subject to the Clean Water Act (CWA). The EPA/Corps guidance reflects the agencies’ inte more...

EPA is now accepting proposals for water quality trading or other market-based projects through its Targeted Watersheds Grants Program. Projects must address reducing nitrogen, phosphorus, sediment, or other pollutant loadings that cause low oxygen levels in local waters and which enter the Mississippi River system. Projects must be located in one of the three Mississippi River sub-basins with the highest nutrient loads contributing to hypoxia in the Northern Gulf of Mexico: the Ohio River, the more...

Drinking water treatment plants, sewer lines, drinking water distribution lines, and storage facilities ensure protection of public health and the environment. As a nation, we have built this extensive network of infrastructure to provide the public with access to water and sanitation. Much of the drinking water and wastewater infrastructure in the US was built 30 years following World War II, mirroring the increase in population.
We cannot ignore the arriving wave of infrastructure rehabilit more...

What is the condition of our waters? EPA, states, tribes, territories, and interstate organizations regularly monitor and report on the physical, chemical, and biological condition of surface waters such as rivers, lakes, estuaries, and coastal waters. These reports may be national in scope and based on statistical survey techniques, or biennial water qualitiy assessment reports submitted by states, tribes and others and summarized by EPA for Congress.

In 1972, Congress enacted the Marine Protection, Research, and Sanctuaries Act Exit EPA Disclaimer (MPRSA, also known as the Ocean Dumping Act) to prohibit the dumping of material into the ocean that would unreasonably degrade or endanger human health or the marine environment. Virtually all material ocean dumped today is dredged material (sediments) removed from the bottom of waterbodies in order to maintain navigation channels and berthing areas. Other materials that are currently ocean dispo more...
