Water tests find bacteria again


Two more tests by the town’s Water Department found levels of nonhazardous coliform bacteria in the public water supply that exceed acceptable limits. Taken on Jan. 4 and Jan. 18, the tests add to a string of coliform alerts in Medfield that goes back to last June. While the bacteria is not harmful, it can be an indicator of other potentially dangerous bacteria in water, officials said. Kenneth Feeney, superintendent of the Department of Public Works, said follow-up tests have shown the points where coliform was detected are now clear. In response to high coliform levels in December, Feeney said, officials wanted the town’s water tower cleaned. The project is still waiting for state Department of Environmental Protection approval, but Feeney said he expects that hurdle to be cleared by Thursday. The tower cleaning, and the installation of a mixer in its tank to prevent sediment buildup, is expected to cost about $40,000.
