In 1948 Congress passed the Federal Water Pollution Control Act (FWPCA). [14] The law authorized the Surgeon General and the Public Health Service to develop programs to combat pollution that was harming surface and underground water sources, but did not create any new regulatory or enforcement authority for pollution control. The FWPCA also ...
The Programme's objectives are to: • Monitor, assess and report on the world's freshwater resources and ecosystems, water use and management, and identify critical issues and problems; • Help countries develop their own assessment capacity; • Raise awareness on current and imminent/future water related challenges to influence the global ...
Nonpoint sources are the most significant single source of water pollution in the United States, accounting for almost half of all water pollution, [1] and agricultural runoff is the single largest source of nonpoint source water pollution. [2] This water pollution has a number of detrimental effects on human health and the environment.
Topsoil runoff from farm, central Iowa (2011). Water pollution in the United States is a growing problem that became critical in the 19th century with the development of mechanized agriculture, mining, and manufacturing industries—although laws and regulations introduced in the late 20th century have improved water quality in many water bodies.

In addition to wastewater discharge monitoring, EPA works with federal, state and local environmental agencies to conduct ambient water monitoring programs in water bodies nationwide. [23] The CWA requires EPA and the states to prepare reports to Congress on the condition of the nation's waters. [24]

The programs now focus not just on improving water quality in an estuary, but on maintaining the integrity of the system as a whole. If all parts of the estuary are not addressed it will be unable to balance the changes and may ecologically collapse, doing more harm than good.
A main focus is nutrient pollution from agricultural runoff of the nation's soybean, corn and food animal production, and problems relating to sediment and toxins. Conservation programs work with local farmers and producers to decrease excess nutrients because they cause major water quality problems along with hypoxia and loss of habitat ...
