Eight months after town health officials first detected a contaminated plume running beneath Edgartown Meadows subdivision, they are turning their attention to installing clean drinking water in the neighborhood instead of pinpointing the cause.

"This has dragged on for more than half a year. It's obviously more of a long-term problem," said Matthew Poole, Edgartown health agent.

"The most important thing is for people to have safe drinking water regardless of whether the source is septic systems or the golf club or something we haven't even considered," he added.
