Groundwater Class Action Affirmed

The Superior Court of New Jersey’s Appellate Division affirmed a class action certification in a lawsuit that claims homeowners in two New Jersey towns suffered home value reductions after what they allege is “abnormally dangerous and hazardous chemicals” in the groundwater by company Hoffman-LaRoche.

The plaintiffs have not stated any health or safety concerns related to the contamination. The claim is related to a notification failure, under the Classification Exception Area, where residents were not properly notified that groundwater sources are unfit for certain uses.

Hoffman-LaRoche closed their 118-acre research facility in 2013. The company has filed third-party complaints against nearly 30 other companies as it says they also contributed to the groundwater contamination. Some of these include Shell Oil and Lockheed Martin. Hoffman-LaRoche fought the certification due to their claim the lower court granted the certification improperly by failing to analyze the evidence.
