The continuing high number of closing and advisory days, combined with a relatively constant level of bacterial contamination at ocean, bay, and Great Lakes beaches, suggests that our nation’s beaches require a more concerted effort to identify and control the sources of water pollution that put swimmers at risk. Even in the relatively dry 2009 beach For the fifth consecutive year, we were able to season, stormwater runoff contributed determine not only the number of closings and advisories, to more than 80% of the closing but also the number of times that each beach violated current public health standards. The percent of beach and advisory days with a reported monitoring samples exceeding national health standards contamination source.
