The Wareham Fire District Water Department hopes to use a $204,250 state grant to purchase 35 acres of woodlands off Glen Charlie Road to help protect the local water supply. Michael A. Martin, the district’s superintendent, said the land is owned by Maple Park Campground LLC of Vermont, and the department will approach the company to “open discussions” about buying the property. Martin said the department has received the easements already. “We’re very grateful for the generosity and cooperation of Maple Park to give us the easements at no cost,” he said. Martin said the department has $400,000 available and that buying the land would not affect Maple Park’s campground operations, because no one camps on that 35-acre portion of the property. The water department hopes to reach a deal soon, because the state grant expires in July.
