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.
The charts below are an example of the reporting features within the 3RQ database. Within several clicks, helpful graphs and summary charts allow users to see their data visually, as well as a list of averages, min, max, etc., without spending valuable time manipulating spreadsheets. Moreover, these reports can be shared easily in a variety of formats, such as pdfs, excel spreadsheets, and word documents.
