To reduce health impacts and encourage economic revitalization, EPA added 2 hazardous waste sites that pose risks to human health and environment to National Priorities List (NPL) of Superfund sites. EPA also proposes adding 6 more sites. According to EPA's Mathy Stanislaus, "Superfund cleanups help advance the economic well-being of communities by turning contaminated properties into productive community resources that can enhance property values, create jobs and broaden tax bases."
