There were more than 20-thousand beach closings and health advisories in the U-S last year because of contamination. That's the worst of any of the 16 years records have been kept.
The Natural Resources Defense Council says the closings show the nation's beaches have serious water pollution problems. The council says the problem is so serious that it's going to sue the Environmental Protection Agency for not modernizing its standards, as ordered by Congress six years ago.
In most cases, the water was contaminated with bacteria. Overall, eight percent of the beach water samples, taken across the country, violated health standards.
The director of the council's Clean Water Project, Nancy Stoner, says a day at the beach shouldn't "turn into a night in the bathroom, or worse, in the hospital." Nine of the 22 beaches rated dirtiest by the council are in California.
