Lake of Ozarks Study Finds No Elevated E. Coli Levels
JEFFERSON CITY - The final water quality sampling of the five-year study of the Lake of the Ozarks found no elevated E. coli.
The geometric mean for the 2011 recreational season at the coves was three E. coli colonies per 100 milliliters of water. This is the lowest geometric mean since the study began in 2007.
The geometric mean at which water is safe for swimming is 126 E. coli colonies per 100 milliliters of water. All of the study's year end results have been below this level.
Over the five years of the study, 2.6 percent of the samples were in excess of the U.S. Environmental Protection Agency's single sample maximum recommended E. coli level for swimming beaches.
