In the course of the Eastern Lakes Survey carried out by the U.S. EPA, acid and base titrations were carried out, dissolved inorganic carbon and pH value were determined to estimate carbonate alkalinity, and dissolved organic carbon was also measured. The data was used to characterize the non-carbonato protolytes in waters relatively rich in organic matter (more than 3 mg organic carbon per litre). The results indicated that slightly coloured, low-alkalinity waters could be acidified by organic acids, waters of higher alkalinity would be influenced by higher concentrations of dissolved organic carbon (more than 7 mg per litre), and hard waters would not be affected.
