Merrimack residents voice concerns over sodium chloride contamination from new development

Concerns over rising sodium chloride levels in Merrimack's drinking water took center stage at the recent Zoning Board meeting on March 26, 2025. Residents voiced alarm over the potential environmental impact of a new development, which includes 69 units and extensive parking areas. Local resident Steve Pippenger highlighted the urgent issue, citing a letter from the Merrimack Village District that warned of increasing sodium chloride levels in the aquifer zone, crucial for the town's drinking water supply.

Pippenger explained that the use of road salt for de-icing during winter months contributes significantly to this contamination. "The cost to treat and remove sodium chloride from our drinking water is prohibitive," he stated, emphasizing the need for the community to protect its water resources. The rising levels have already forced the district to inactivate one of its highest-producing wells, raising concerns about future water quality and safety.

Legal implications were also a hot topic during the meeting. Attorney Donald Weiss cautioned that approving the variance for the new development could set a dangerous precedent, allowing future developers to bypass zoning regulations. "If this board approves this variance... any lawyer for any developer in the future... will cite this as a precedent," Weiss warned, underscoring the potential long-term consequences of the board's decision.

As discussions continue, the community remains on alert regarding the balance between development and environmental protection. The Zoning Board's upcoming decisions will be critical in shaping Merrimack's future and safeguarding its vital water resources.
