Another round of beaches closed Wednesday because of harmful bacteria levels. Unfortunately, the ‘no-swimming’ warnings you get are usually too late. Also, as of now it’s almost impossible to find out where the bacteria is coming from.

On Wednesday, another round of Palm Beach County beaches were closed because of harmful bacteria levels that were in some cases nearly three times higher than what is needed for an advisory. The closures mark 14 times this year advisories were issued at county beaches. In all of 2018, 15 advisories were issued.

...a lack of water circulation and heavy runoff are likely key reasons for enterococcus advisories. That could be why the Gulf Coast suffers more advisory days with runoff from rivers such as the Hillsborough into Tampa Bay, the Peace River into Charlotte Harbor and the Caloosahatchee River into San Carlos Bay.

“The biggest thing I would think is the flushing,” said Sullivan, noting that testing for enterococci is a laborious process that can take two days. “An E. coli detector is the holy grail of technology.”
