The Michigan Environmental Council (MEC) and the Rochester Junior Women's Club will hold a drinking water town hall to give residents the opportunity to learn more about their drinking water. The event, which will be held from 6:30 p.m. to 8 p.m. on June 2 at the Rochester Hills Public Library, will offer residents the chance to learn where their drinking water comes from, how it is treated and transported and what contaminants are potentially present.
