Print Friendly, PDF & Email

The Ohio River is formed by the confluence of the Allgheny and Monongahela River in downtown Pittsburgh, PA.  The river is 981 miles long and flows to the Mississippi River at Cairo, IL.  For the 3RQ program, our geographical focus is on the Upper Ohio River Basin, which is below the confluence of the Allegheny and Monongahela River Basins to the confluence with the Kanawha River Basin.

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.

Reporting Features

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.
