The upcoming July 4th holiday weekend is expected to be hot, and many people will head to the beach to cool off with a swim in the ocean. However, the Department of Health in Miami-Dade is warning people to stay out of the water at three specific beaches due to a higher-than-acceptable level of bacteria. They have issued a water quality advisory for Oleta River State Park in North Miami Beach, 93rd Street in Surfside, and 21st Street in Miami Beach.

Elevated levels of enterococcus bacteria found in these areas can indicate fecal pollution, which may come from various sources such as stormwater runoff, wildlife, pets, and human sewage. The health department strongly advises against engaging in any water-related activities at these beaches, as swimming in the water could increase the risk of getting sick, especially for individuals with pre-existing health conditions.

John MacLauchlan is a digital content producer for CBS Miami who provides information on the current water quality advisory and the potential risks associated with swimming at the affected beaches. He is a graduate of Florida State University with a degree in Communications and has been part of the CBS Miami digital team since February 2007.
