SLA & PSU to Host Public Meeting Concerning Recent Contaminants Found in Squam Watershed

On Wednesday, November 1st the Squam Lakes Association and PSU’s Center for the Environment invite the public to attend a panel discussion pertaining to recent findings of environmentally significant levels of persistent organic pollutants (POP) in sediments of certain streams draining into Squam Lake.  This public meeting will be held at Plymouth State University's Boyd Science Center, Room #144 at 5:30pm.

A report released by the Loon Preservation Committee this year showed three sampled sites in the Squam watershed contained environmentally significant levels of PCBs. Two of those sites had elevated levels of DDT. Previous analysis of unhatched loon eggs showed presence of significant levels of PCBs, dioxins, flame retardants, stain guards, and pesticides (DDT and chlordane).

“This meeting will provide best available balanced information from environmental experts in the state,” said SLA Director of Conservation, Rebecca Hanson.

Panelists at this meeting will discuss issues pertaining to POP sources and persistence, effects to ecosystem and human health, and private property liability and legacy contaminants. This meeting will also focus on next steps for surveying and identifying legacy sources and potential for confinement and remediation.

Boyd Science Center is located on Highland Street next to PSU's Lamson Library. Parking is available on Highland Street. Please click here for PSU campus map.
