The number of closing and advisory days at ocean, bay, and Great Lakes beaches jumped 28 percent to more than 25,000, confirming that our nation’s beaches continue to suffer from se- rious water pollution. For the second consecutive year, we were able to determine not only the number of closings and advisories, but also the number of times that each beach violated current public health standards. This year, a curious picture emerged: while the number of closing/advisory days increased, the percent of all samples exceeding national health standards decreased to 7 percent in 2006 from 8 percent in 2005. The culprit is stormwater runoff: the number of closing/advisory days due to stormwater doubled to more than 10,000 in 2006. The structures and infrastructures of our coastal cities and towns The EPA missed its congressionally create the conditions for rain to wash infectious bacteria, vi- mandated deadline to revise the ruses, and parasites into our beachwater. In fact, in many of current public health standards the more populated coastal areas, health officials are so sure that heavy rains will wash sewage, nutrients, and debris into for beachwater quality, which are our coastal recreational waters, that they don’t even wait for outdated and inadequate. the results of monitoring before taking action to protect the public – they close beaches or issue advisories preemptively. In 2006, 79 percent of the closing/advisory days due to stormwater contamination were preemptive. Hawaii, which had record amounts of rain in 2006, accounts for the largest share of preemptive closing/advisory days. CLOSINGS AND ADVISORIES INCREASE AT HIGH-RISK BEACHES For the first time this year, our report puts a special focus on our nation’s highest risk beaches—those with the great- est amount of use and/or proximity to potential pollution sources. This new area of focus is the result of a peer review process NRDC undertook with five professionals from local and state health agencies, academia, and the research com- munity. States must identify their highest risk beaches when they receive federal Beaches Environmental Assessment and Coastal Health Act (BEACH Act) grants from the Environmental Protection Agency (EPA). We found that closing/ad- visory days at these so-called “Tier 1” beaches steadily increased at a rate of 3 percent per year from 2004 through 2006. Heavy rains in some areas, more frequent monitoring, and uncontrolled stormwater and sewage pollution appear to be the major factors contributing to the steady increase. Ninety-seven percent of Tier 1 beaches are monitored at least once a week compared to 79 percent of all monitored beaches.
