At an all-staff meeting of the New Hampshire Department of Environmental Services March 20, Mary Butow was presented with her 2018 P2 Educator of the Year (Most Valuable Player) award by Rick Reibstein of the NPPR Board. Mary developed educational services to inform people of toxic constituents in what they use, and performed other significantly valuable research and informational assistance for the public while working as the librarian of the Toxics Use Reduction Institute at the University of Massachusetts at Lowell. Now she is tasked with informing the citizens of New Hampshire of the latest scientific understanding of their newest emerging contaminant, per- and polyfluoroalkyl substances (PFAS). Presenting the award was a great opportunity, afforded by NHDES Commissioner Robert Scott, to remind everyone of the value of the preventive approach. Mary’s whole career exemplifies the importance of thinking about what you are using. The presenter noted that had that approach been applied to the releases and dispersive uses of the PFAS class, we would not have the problems we have today of its persistence in groundwater.
