Voters in three Island towns will head to the polls Thursday for annual town elections. There are few contested races, and voters will be asked to weigh in issues ranging from fluoridating town water to town spending.

Oak Bluffs voters will decide a contested race for the board of selectmen, with five candidates vying for two seats on the board. Incumbents Kathleen Burton and Gregory Coogan face challenges from newcomers Brian Packish, Abraham Seiman, and Raymond Taylor in the only contested race on the ballot.

Voters will also be asked to decide whether to stop fluoridating the town water supply. Oak Bluffs is the only town on the Island to fluoridate its water supply, but the board of health is considering ending fluoridation, and seeks guidance from voters.

Polling hours are 10 a.m. to 7 p.m. in the meeting room at the town library.

Edgartown voters will head to the town hall meeting room from 10 a.m. to 7 p.m. for the annual town election. There is one race on the ballot; incumbent parks commissioner Joel Graves faces a challenge from Kevin Searle. Arthur Smadbeck is running unopposed for his third term on the board of selectmen.

Voters will also be asked to approve Proposition 2 1/2 debt exemptions that would allow the town to exceed the tax levy for paving Meetinghouse Way, funding a new superintendent’s building and the purchase of a new building for the Dukes County Center for Living. All three of those spending items were approved by town meeting voters Tuesday.

There are no contested races on the West Tisbury ballot, although four-term incumbent selectman Jeffrey (Skipper) Manter 3rd will be challenged by write-in candidate Benoit Baldwin. West Tisbury voters will be asked to weigh in on debt exclusions to fund the Center for Living and repairs to the West Tisbury school and whether to approve funding for the Up-Island regional school district assessment and a new playground at West Tisbury school. Polls are open from 7 a.m. to 8 p.m. at the public safety building.
