An analysis of well water tests by the nonprofit environmental watchdog group Raritan Headwaters Association (RHA) has detected a “disturbing increase” in concentrations of arsenic, a known carcinogen, according to a study released on Thursday, June 9… “No law requires that homeowners test their wells except when selling their property to someone else, a requirement to protect the buyer only,” noted Daniel Van Abs, associate research professor for Water, Society and Environment at the Rutgers School of Environmental and Biological Sciences. The analysis was peer reviewed by Richard Lathrop, professor of environmental monitoring and restoration ecology at Rutgers University’s School of Environmental and Biological Sciences.
