elijah_the_man on 23 Oct 14United States Geological Survey (USGS)'s article discusses the definition of pH, its importance, measurement, pH in water quality and pH variation across the US. It's purpose is to get an understanding of what pH is and how it plays a role in the US. The source proved very useful, providing accurate information (some information came from a 2002 country pH survey!).
