NORWALK - A new report says Connecticut has some of the best quality swimming water in the country, but the state still has a problem with pollution.

The National Resources Defence Council found that 108 state beaches were closed last year, down from 135 in 2008.

Byram Beach in Greenwich was closed 20 times last year, more than any other beach.

Calf Pasture and Shady beaches in Norwalk were each closed seven times.

The report says the closings often follow heavy rains that wash pollution into the water.
