Four areas at state parks are closed to swimmers today due to increased bacteria in the water.  Kettletown State Park in Southbury and Indian Wells State Park in Shelton are closed for swimming.  The state Department of Energy and Environmental Protection has now added Silver Sands in Milford and Sherwood Island in Westport to the closure list. 

Water retesting is being scheduled by DEEP to determine when it is safe to reopen. 

After heavy rain, storm water runoff can increase the amount of bacteria in the water.  Water quality testing is done on a regular basis by DEEP at swim areas at state parks.
