A young Ohio business, Blue Water Satellite, Inc., is using Landsat 5 and 7 data to detect potentially harmful pollutants in water bodies across the U.S. used for recreation and for drinking water supplies. Using Landsat and algorithms developed at Ohio’s Bowling Green State University, Blue Water can detect E. Coli, cyanobacteria, phosphorus, and Red Tide. Dr. Robert K. Vincent, a geology professor at BGSU, used NASA and NOAA grant money to help develop the pollutant-detection algorithms.
