NH HB 398 requires PFAS disclosure in real estate transactions

New Hampshire HB 398 requires home sellers to notify potential buyers about the possibility of PFAS water contamination prior to executing any contract for sale of real property. Sellers must alert buyers that PFAS have been found throughout New Hampshire exceeding state and federal standards, and inform them that testing can determine if water filtration systems are needed. PFAS was added to existing mandatory disclosure requirements alongside radon, lead, and arsenic. The requirement does not apply to rental properties.
