The West Lake pond of Monponsett stinks–algae has turned the former pristine water to green slime. It’s visible on Google Earth satellite photos, and it’s spread to the East Lake, to Pembroke’s ponds and to Kingston’s Silver Lake. Wetlands, brooks and the Brockton water supply conduits all connect the the ponds and lakes of Halifax, Hanson, Pembroke and Kingston.
Water run-off from lawns and roads, pond-side septic systems, cranberry bog fertilizers all contribute to algae blooms in local ponds by feeding phosphorus to the algae. The algae clogs the water and emits a foul odor when the phosphorus meets summer sun. The algae die and fill the bottom of ponds and lakes.
Halifax health board chairman John Delano has initiated a regional association to attack the problem – the Monponsett Watershed Association. A kick-off meeting Thursday night in the Halifax Town Hall attracted a wide array of people facing the problem.
Delano told them they should act before the state’s Department of Environmental Protection forces them to act.
“My goal for forming a watershed association is to have a unified, regional approach to solving the water quality problem of the Monponsett ponds,” Delano said. “I think we need to take a grassroots approach from the region and solve the problem of feeding the algae with pollutants that are getting into the water.”
