The report shows beach closings due to pollution remained high last year. The National Resources Defense Council reports 200 popular beaches across the nation totaled 20,000 days of closings and advisories.
It's the fourth worst showing for beaches since the council began tracking beaches 19 years ago. The report says rain plays a big role in flushing pollutants into the oceans and it's been pretty dry in California.
Two popular San Francisco beaches are among the U.S. beaches looked at.
"Ocean Beach and Baker Beach did fairly well. Among the 200 beaches we surveyed, they got two and three star ratings; which means the water quality is okay, but there is room for improvement," said Leyla Monroe of the Nat. Resources Defense Council.
