GROTON -- Selectmen Monday night met with the Water Commission and the Great Ponds Advisory Committee to clear the air over a decision to nix a plan to use weed-killing chemicals in Baddacook Pond.
The Great Ponds committee wishes to use chemicals to clear the pond of weeds that threaten to take it over, ruin public use and endanger the local environment.
However, fearful of harm coming to its nearby well site, the Water Commission voted against the plan.
After being requested by Haddad, selectmen decided to meet with both parties to listen to new information given by committee Chairman James Leuning.
The hope by the board and committee members was that the new information would be sufficient for the Water Commission to reconsider its vote.
According to Leuning, information from the state's Department of Environmental Protection indicates that use of the chemicals is allowed on the pond and that study of similar uses of chemicals in Natick found no harm had come to its groundwater.
In fact, said Leuning, salt and asperin are more toxic than chemicals, such as Sonar, used to control aquatic weeds.
Luening finished by reminding those in attendance that alternate forms of weed control are either too expensive or ineffective.
Board of Health member Susan Horowitz told selectmen that use of Sonar in Lost Lake has not shown up in the nearby Whitney well site. In order to make a proper decision, the latest scientific information must be examined, she said.
The hearing ended with no decision on the issue.
When asked, water superintendent and Water Commission member Thomas Orcutt could not say whether the question would be taken up again by the Water Commission.
