Detection Limits

The upper concentration limit (UCL), lower concentration limit (LCL), and mean levels of sulfate in the mainstem streams of the Allegheny River are displayed in the graphs below. The first graph measures sulfate output in miligrams per liter, while the second graph calculates the sulfate tons per day (tpd).

Sulfate is a salt consisting of one sulfur atom and four oxygen atoms with an oxidation number of -2. Sulfate is naturally occurring in almost all water bodies. It usually comes from oxidation of sulfite ores, dissolution of sulfate minerals, shale, and industrial wastes. High concentrations of dissolved sulfate may give water an unpleasant taste and may be corrosive to plumbing. It may also have health effects including nausea and diarrhea.
