Troubled waters: Infrastructure woes dirty some Texas beaches

As more families head to Texas beaches this summer, some beachgoers might return from vacation with an unfortunate waterborne illness.
An annual report recently published by Environment Texas warns that pathogens pose a threat to swimmers at 90 percent of Texas beaches. Yet, Cameron Countys beaches stood out as the safest in the state.
Last year, 55 out of 61 beach locations monitored by Texas Beach Watch for fecal indicator bacteria were potentially unsafe for swimming on at least one day, according to the Safe for Swimming report, an annual analysis conducted by the Environment Texas Research and Policy Center that was released July 1.
Whenever fecal indicator bacteria levels exceed the U.S. Environmental Protection Agencys most protective Beach Action Value, an estimated of 32 out of every 1,000 swimmers are sickened, according to the report.
