Utah Real-time Water Quality

Utah Real-time Water Quality

Real-time computed concentrations of water-quality constituents such as suspended sediment, total nitrogen, and total phosphorus are calculated using ordinary least squares regression models. The results of these models, along with direct water-quality measurements, can be viewed here as time-series graphs, or downloaded as tabular data.

Ordinary least squares regression models on this site use conventional sensor measurements (for example, discharge, temperature, pH, specific conductance, turbidity, and dissolved oxygen) to compute concentrations and loads of other water-quality constituents in real time. This makes it possible to compute instantaneous values of many constituents in real time for public safety without the lengthy time delay of collecting a sample and waiting for analysis of a sample at a laboratory.
