Ohio-Kentucky-Indiana Water Science Center


Ohio Kentucky Indiana Water Science Center Laboratories

The U.S. Geological Survey (USGS), Ohio Water Microbiology Laboratory (OWML) addresses water-related public-health concerns for Ohio and the rest of the Nation. The OWML is involved in investigations of processes that affect microorganisms in the environment and testing of new methods to improve detection and interpretation of microbiological presence in water. 

The U.S. Geological Survey (USGS) , Kentucky Sediment Laboratory performs an analysis of physical characteristics of fluvial sediment, which determines the suspended-sediment concentration (SSC), fine/sand separation, and particle size distribution (PSD).

Using models to estimate microcystin concentrations in Ohio recreational and source waters

Cyanobacterial harmful algal blooms (cyanoHABs) and associated toxins, such as microcystin, are a major global water-quality issue.  In Lake Erie and inland lakes in Ohio, elevated microcystin concentrations have caused water-resource managers to issue recreational water-quality advisories, and detections of microcystin in source waters have caused drinking-water plant managers to increase...
