According to the Florida Department of Environmental Protection, the Sarasota County Lockwood Ridge booster station failed the afternoon of July 9, causing about 36,000 gallons of untreated wastewater to spill from the Siesta Key Master Lift Station into Grand Canal in the 5100 block of Oakmont Place. About 14,700 gallons was recovered.

In the advisory, people were urged to take precautions when in contact with the waters of Grand Canal. Water contaminated with wastewater overflow presents several health risks to humans. Untreated human sewage with microbes could cause gastrointestinal issues and other conditions.
