Ph of precipitation
WebbAbstract: The pH and salinity of water are important monitoring indicators of the Chinese Ecosystem Research Network (CERN), which can provide important data for the study of long-term changes of water within ecosystems. The pH of precipitation can indicate whether it is acid deposition or not. http://www.subtleenergies.com/ormus/research/precip.htm
