AWWA JAW10916

Concentrations of 2-methylisoborneol (MIB) forced The Metropolitan Water District of Southern California to shut down a critical water supply reservoir in 1980 and 1981. An algae control measure developed as a result of these experiences was used to correct a taste and odor problem in the reservoir in 1982. The application of 26,760 kg (59,000 lb) of copper sulfate, applied from a boat equipped with a modified agricultural spreader, eliminated growths of blue-green algae in five days. The closed-loop stripping analysis (CLSA) technique for earthy-musty odorants was used to isolate the locations of Oscillatoria curviceps, responsible for MIB production, and Oscillatoria splendida, responsible for a short-lived geosmin appearance. Includes 17 references, tables, figures.
