Meeting Jan. 24 to discuss Round Lake water contaminants

The village of Round Lake will hold a public meeting Jan. 24, to discuss what’s being done about elevated levels of potentially hazardous chemicals in the village drinking water.

Levels of trihalomethanes, which are a by-product of chlorine water disinfection, are slightly above the 0.08 milligrams per liter maximum safe standard set by the state Health Department — high enough to prompt quarterly notices being sent out to the village’s 305 households.

The Saratoga County Water Authority, which is the ultimate supplier of the village’s water, has had an ongoing problem with disinfection by-products since the fall of 2011.

“It’s got to end,” said village Mayor Dixie Lee Sacks. “As far as I’m concerned, they’re selling us a product, and it’s not meeting specifications.”

Village, county and state officials agree there’s no immediate health risk from the traces of trihalomethanes, though long-term exposure is a risk.

The water authority is taking a variety of steps to address the ongoing problem, said Ed Hernandez, its acting director.

“We have been steadily improving,” he said Wednesday. “But because of long detention times in the system, in communities at the end of the line like Round Lake and Stillwater, it continues to be a problem.”

Trihalomethanes form from the chemical reactions between chlorine and organic materials in the water, so the longer the water goes between chlorination and consumption, the higher the trihalomethane concentration.

Round Lake, a village of about 625 people that uses about 36,000 gallons per day, buys its water from the Clifton Park Water Authority, which purchases part of its supply from the county water authority. The county authority draws its water from the Hudson River in Moreau, and pipes it 27 miles south to the central part of the county.

The county authority has been working on the issue since high levels of chlorination by-products were first detected in September 2011. The authority recently formed a technical committee to discuss more possible solutions.

Hernandez said the authority has been flushing the system more often, changing the disinfection blend and taking other measures, but it can take time to see how well they are working. “We may have to do some more localized further treatments,” he said.

The village meeting, to be held at 7 p.m. Jan 24 in the Village Hall community room, will include representatives of the state Health Department, county water authority, Clifton Park Water Authority, and Lamont Engineers of Cobleskill, the village engineers.
