With heavy rain and flooding expected from Hurricane Florence, residents are reminded to avoid the water and bubbling manholes.

Flood water and standing water pose various risks, including infectious diseases, chemical hazards, and injuries, according to the Centers for Disease Control.

Here’s why.

During heavy rain events, storm water infiltrates the sewer system through cracked pipes, taking up system capacity, raising the level of the sewage, and occasionally pushing it up through manholes into the street where people and pets may contact it, according to a spokesman with Charleston Water System. 

Water runoff also contains contaminates from yards, like pet waste.

Flood waters can displace animals, insects, and reptiles, which may bite. 

Health experts warn to avoid the water and clean toys after the water subsides.
