6. Many Beaches Across the U.S.
There are thousands of miles of coastline across the country, and some of it is in better shape than others. You’ll find polluted beaches in every state with a coastline — largely due to storm water. You never want to swim in a beach that has posted warnings. You should also avoid city beaches after it has rained. But just because there’s no warning doesn’t mean the beach is safe. Nearly half of beaches aren’t monitored at all, and, of the ones that are, only 45 percent are monitor at least once a week.
Instead Try: The NRDC has a searchable list of popular beaches across the country. Find a five star beach in your area. The list isn’t comprehensive, though, and the NRDC recommends finding out how often your beach of choice is monitored, because nearly half of beaches aren’t.
