A group of researchers at Cornell University has developed a new, faster test to determine whether bacteria are present in beach water.

Beaches are supposed to close to swimmers when bacteria levels in the water surpass state limits, but the test in use in most of the Great Lakes region takes 24 hours to return results, leaving swimmers at risk in the meantime, said Ruth Richardson, an engineering professor at Cornell University.



Today, local teens are hitting the beach for more than just a little "fun in the sun."

They're participating in a study to investigate an ongoing problem in the community, the water.
