GLENVILLE — Work to bring public water to about 100 homes in the path of a contaminated brownfield site's underground plume is complete, the state Department of Environmental Conservation said Tuesday.
The $2 million project has brought town water to the Sunnyside Gardens-Sunnyside Road neighborhood, which is just south where the former Kenco Chemical Company on Freemans Bridge Road left groundwater contamination that has spread.
The water line extension work began in 2015 after it was determined contaminants from the Kenco site had spread to the groundwater at the northern end of the neighborhood. Residents were told they should stop using their wells. A separate ongoing DEC study is looking at ways to remediate the contamination.
"Protecting public health in these neighborhoods is DEC's top priority and the quick completion of this project to connect these homes to the public water supply will ensure these families have access to a steady source of clean drinking water," DEC Commissioner Basil Seggos said in a prepared statement. "I commend our staff for working quickly to advance this portion of our remediation project as we continue to address contamination in the area."
A contractor hired by DEC installed 2,800 feet of 12-inch water main along Sunnyside Road and 4,080-feet of 8-inch line throughout the Sunnyside Gardens neighborhood. The connections were made and the work declared finished this fall after property restoration and warranty work was done.
The $2 million cost is coming from the state Superfund program.
The contamination was discovered in 2006 as plans were being made for a Lowe's Home Improvement store. Subsequent testing determined that contaminants from the one-acre Kenco site had spread as far at the Sunnyside area, the nearest residential development.
"I want to thank the DEC for all their work in ensuring that our residents are on the town's safe and clean water supply," said Town Supervisor Chris Koetzle. "This was a critically important project to our residents and I am proud that the town and the state worked so closely together to ensure they were protected from any potential threat."
The Kenco site at 107 Freemans Bridge Road was historically used for chemical distribition and warehousing, according to DEC, with activity ceasing in about 1999. The identified contaminants include volatile organic compounds such as dichloroethene, trichloroethene, and tetrachloroethene.
DEC officials said a remediation program is being developed, with work expected to begin next year. It's expected to last a decade or longer at an estimated cost of around $14 million to $16 million.
Documents related to the project are also available at the Glenville Public Library, 20 Glenridge Road, Glenville.
