Full Text of CPLR 214-h
Plain-English Summary
CPLR 214-h addresses litigation over contaminated public water systems — cases involving PFAS, 1,4-dioxane, and other substances the section calls emerging contaminants. It defines who qualifies as a public water supplier or wholesale water supplier by reference to the number of connections or people served, and it defines the technical terms that matter for accrual: contaminant, source of water supply, plant intake, well, and raw water.
A supplier's three-year period runs from the latest of three triggering events: detection of a contaminant above a regulatory notification, action, or maximum contaminant level; the last wrongful act by any person whose conduct contributed to the contamination; or the last detection of the contaminant above the relevant regulatory level. Critically, this calculation applies separately to each well and each plant intake, so the expiration of the period for one location has no effect on a separate claim tied to a different well or intake.
The section preserves a supplier's right to sue for abatement of an imminent contamination threat regardless of these deadlines, and it includes its own revival window: claims involving an emerging contaminant that were already barred as of a 2022 amendment's effective date could still be commenced, provided suit was filed before or within eighteen months after that date.
CPLR 214-h extends the same discovery-based logic found in CPLR 214-c, 214-b, and 214-f to an institutional plaintiff — a water supplier — rather than an individual injury victim, applying the family's shared principle that a claim shouldn't be measured from the contamination itself when detection takes years.
Frequently Asked Questions
What does CPLR 214-h cover?
Damage to property owned, managed, or operated by a public or wholesale water supplier resulting from the presence of a contaminant in its source of water supply.
How long does a water supplier have to sue over contamination?
Three years from the latest of specified triggering events, including detection of a contaminant above a regulatory level or the last wrongful act contributing to the contamination.
Does the three-year deadline run separately for each well?
Yes. The period applies separately to each well and each plant intake, so its expiration at one location doesn't affect a claim tied to another.
Can a water supplier always sue to stop an ongoing contamination threat, regardless of this deadline?
Yes. CPLR 214-h preserves the right to bring an action to abate an imminent threat of contamination, or to recover the costs of that abatement, without regard to the three-year period.
Is there a revival window for older emerging-contaminant claims under CPLR 214-h?
Yes. Claims involving an emerging contaminant that were already barred as of a 2022 amendment's effective date could still be brought before, or within eighteen months after, that date.
