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. [1] [2] The more acidic the acid rain is, the lower its pH is. [2] Acid rain can have harmful effects on plants, aquatic animals, and infrastructure.
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.

Robert Angus Smith FRS (15 February 1817 – 12 May 1884), commonly referred to as Angus Smith, [1] was a Scottish chemist, who investigated numerous environmental issues.He is known for his research on air pollution in 1852, in the course of which he discovered what came to be known as acid rain.
Turów Power Station, a thermal power station in Bogatynia, Poland Effects of acid rain in the Jizera Mountains in 2006. The Black Triangle (German: Schwarzes Dreieck, Lower Sorbian: Carny tsirozk, Upper Sorbian: Čorny trirózk) is the border region between Germany, Poland and the Czech Republic, long characterized by extremely high levels of pollution.
After the Civil War, smelting operations, which were used to separate sulfur from the copper ore, resulted in acid rain in the area. Combined with the logging of nearby forests to fuel the smelters, this resulted in a massive environmental disaster that left the surrounding landscape barren for more than a century. Several mines, the largest of ...

Flash flood; Rainstorm
Likens is best known for leading the team of scientists that discovered acid rain in North America, and connected fossil fuels with increasing acidity of precipitation. [1] [2] In addition to its scientific impact, this work has influenced public debate and governmental policy, particularly the United States Congress's Clean Air Act Amendments ...
