National Estuary Program - EPA's National Estuary Program was established by Congress in 1987 to improve the quality of estuaries of national importance.
Gulf of Mexico Program - Dedicated to finding and applying environmental solutions that work in concert with sound economic development. Our many partners from Alabama, Florida, Louisiana, Mississippi and Texas work hard to protect the 1.8 million square miles that make up the beautiful waters of the Gulf.
Wetlands - The Clean Water Act is a 1977 amendment to the Federal Water Pollution Control Act of 1972, which set the basic structure for regulating discharges of pollutants to waters of the United States.
Section 404 - establishes a program to regulate the discharge of dredged and fill material into waters of the United States, including wetlands.
Great Waters Program - On November 15, 1990, in response to mounting evidence that air pollution contributes to water pollution, Congress amended the Clean Air Act and included provisions that established research and reporting requirements related to the deposition of hazardous air pollutants to the "Great Waters." The water bodies designated by these provisions are the Great Lakes, Lake Champlain, and Chesapeake Bay, and certain other coastal waters (identified by their designation as sites in the National Estuarine Research Reserve System or the National Estuary Program).
Great Lakes National Program Office (GLNPO) - The Great Lakes National Program Office oversees and helps all Great Lakes stakeholders work together in an integrated, ecosystem approach to protect, maintain, and restore the chemical, biological, and physical integrity of the Great Lakes.
Rivers and Streams - Information on programs and actions to protect and restore rivers, streams and other aquatic resources.
Mercury - Mercury is a naturally occurring element that is present throughout the environment. Human activity can release some of that mercury into the air, water and soil. This site provides information on effects on health and wildlife, regulatory programs, and spill clean-up/waste disposal. 
Ocean Regulatory Programs - This site has information about ocean dumping and dredged material management, marine and ocean discharges, vessel discharges.
Beaches - Consists of five areas to meet the program goals of improving public health and environmental protection programs for beach goers and providing the public with information about the quality of their beach water.

Oceans, Coasts, & Estuaries - Coastal environments are strongly influenced by upstream sources of pollution and freshwater inflow, and are subject to an ever-growing coastal population. EPA protects these resources through a watershed approach and its regulatory and cooperative management programs.
Total Maximum Daily Loads (TMDLs) - A calculation of the maximum amount of a pollutant that a water body can receive and still meet water quality standards, and an allocation of that amount to the pollutant's sources. The Clean Water Act, section 303, establishes the water quality standards and TMDL programs.

Chesapeake Bay Program - EPA's Chesapeake Bay Program Office coordinates the goals of the Chesapeake Bay Program (CBP) with the other offices located in EPA's regional office in Philadelphia, Pennsylvania. The CBP is a unique regional partnership leading and directing restoration of the Chesapeake Bay. Our mission is to lead and empower others to protect and restore the Chesapeake Bay ecosystem for future generations.

Great Lakes Information Network (GLIN) - The Great Lakes Information Network is a partnership that provides one place online for people to find information relating to the binational Great Lakes-St. Lawrence region of North America.
GLIN offers a wealth of data and information about the region's environment, economy, tourism, education and more. Thanks to its strong network of state, provincial, federal and regional partner agencies and organizations, GLIN has become a necessary component of informed decision making, and a trusted and reliable source of information for those who live, work or have an interest in the Great Lakes region.
