The measure, known as the San Francisco Bay Clean Water, Pollution Prevention and Habitat Restoration Program or Measure AA, passed by the required 2/3 majority in the combined county vote. The measure provides for $500 million in funding for the authority, to be used to restore wetlands and mitigate expected sea level rise. [1] [2] [3] [4]
The Clean Water Act governs pollution of surface waters. [42] In the first several decades since enactment of the 1972 law, EPA and states’ approach to mercury pollution focused on discharges to surface waters from point sources (principally factories, power plants, and sewage treatment plants). A variety of mercury discharge standards have ...
Pollution prevention (P2) is a strategy for reducing the amount of waste created and released into the environment, particularly by industrial facilities, agriculture, or consumers. Many large corporations view P2 as a method of improving the efficiency and profitability of production processes through waste reduction and technology ...
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.

This act applies to surface water, groundwater, wetlands and both point and nonpoint sources of pollution. There are nine regional water boards and one state water board that have resulted from this act. The act requires the adoption of water quality control plans that contain the guiding policies of water pollution management in California.
The difference with water pollution, however, is that the problems that cause local water quality issues differ from those that create regional air pollution problems. Discharges into water are difficult to measure and effects are dependent on a variety of other factors and vary with weather and location.
It also administers a fund to help underground storage tank owners and operators pay for the costs of cleaning up leaking underground storage tanks. The State Water Board coordinates the state's nine Regional Water Quality Control Boards (Regional Water Boards), which serve as the frontline for state and federal water pollution control efforts.
Complete removal of ions from water is possible if the right conditions are met. The water is normally pre-treated with a reverse osmosis unit to remove non-ionic organic contaminants, and with gas transfer membranes to remove carbon dioxide. A water recovery of 99% is possible if the concentrate stream is fed to the RO inlet.
