Valley Interfaith is drawing a connection between stories of cancer-related deaths, three gas stations and a benzene plume moving through a neighborhood blocks from St. Joseph the Worker Catholic Church in McAllen. Leaders are in the midst of a research campaign with the Texas Commission on Environmental Quality (TCEQ), Texas state legislators and County Commissioners to get to the bottom of the benzene plume. Discovery of the toxic gas plume emerged from a listening campaign about the concerns of Rio Grande Valley residents.
