Merrimack Wastewater Facility faces PFAS contamination challenges from Saint Gobain's operations

The New Hampshire Environmental Services Department's recent meeting highlighted critical concerns regarding PFAS contamination linked to the Merrimack Wastewater Facility and its impact on local water quality. A significant focus was placed on the facility's requirement for Saint-Gobain to implement a pre-sanitary sewer filtration system, aimed at reducing the discharge of harmful substances into the sewer system. Despite these measures, ongoing testing revealed that PFAS levels in compost produced from biosolids remain alarmingly high, raising serious public health concerns.

Participants in the meeting expressed frustration over the inadequacy of current regulations governing PFAS emissions and the management of wastewater. The discussion underscored the need for stricter oversight, particularly regarding storm drains and other pathways that contribute to contamination. One speaker noted that water samples taken from local drains showed elevated PFAS levels, indicating that the problem persists despite efforts to mitigate it.

The meeting also touched on the broader implications of PFAS contamination in the food chain, emphasizing that agricultural practices and the use of contaminated biosolids could lead to further environmental and health risks. The Manchester Wastewater Facility was mentioned as the only facility in the region that incinerates sludge, raising questions about the safety and effectiveness of current disposal methods.

As the community grapples with these challenges, the need for comprehensive regulatory reforms and proactive measures to address PFAS contamination has never been more urgent. The discussions from this meeting signal a pivotal moment for New Hampshire as stakeholders seek to protect public health and the environment from the ongoing threat of PFAS pollution.
