Acid rain is rain or any other form of precipitation that is unusually acidic, meaning that it has elevated levels of hydrogen ions (low pH).Most water, including drinking water, has a neutral pH that exists between 6.5 and 8.5, but acid rain has a pH level lower than this and ranges from 4–5 on average.
Established in 1991, the Acid Rain Annex aimed at reducing and , the main contributors of acid rain. The annex includes preventative measures aimed at minimizing declining air quality, visibility impairment, and actively monitoring emissions. [13]
The Acid Rain Program (ARP) is an emissions trading program for power plants to control the pollutants that cause acid rain. [13] The 1990 CAA Amendments created a new title to address the issue of acid rain, and particularly nitrogen oxides (NO x ) and sulfur dioxide (SO 2 ) emissions from electric power plants powered by fossil fuels, and ...
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 ...
Diagram depicting the sources and cycles of acid rain precipitation. Freshwater acidification occurs when acidic inputs enter a body of fresh water through the weathering of rocks, invasion of acidifying gas (e.g. carbon dioxide), or by the reduction of acid anions, like sulfate and nitrate within a lake, pond, or reservoir.

The Acid Rain Retirement Fund (A.R.R.F) is an all-volunteer, non-profit environmental educational organization, incorporated in Maine, dedicated to reducing pollution by purchasing and "retiring" marketable sulfur dioxide emissions allowances issued by the U.S. Environmental Protection Agency’s Acid Rain Program. A.R.R.F. was created in 1995 ...
Increased dissolution of carbonate rock by acidification from acid rain and mining has contributed to increased alkalinity concentrations in some major rivers throughout the eastern U.S. [7] The following reaction shows how acid rain, containing sulfuric acid, can have the effect of increasing river alkalinity by increasing the amount of ...
The rows formed slow surface water run-off during rainstorms to prevent soil erosion and allow the water time to infiltrate into the soil. Soil conservation is the prevention of loss of the topmost layer of the soil from erosion or prevention of reduced fertility caused by over usage, acidification, salinization or other chemical soil contamination
