This year marks 100 years of flood protection by MCD

While there is a persistent fear of flooding in cities around the world, people and businesses along the Great Miami River go confidently about their lives hardly giving flooding a thought. Since 1922, homes and businesses are protected by MCD’s system of five dry dams, retarding basins, 55 miles of levees, and preserved floodplain which provide a nearly unparalleled level of protection.

PFAS Part IV – PFAS in Major Rivers of the Great Miami River Watershed

Recent river water sampling by the Miami Conservancy District (MCD) shows some Per- and Polyfluoroalkyl Substances (PFAS) compounds appear to be present in the major rivers that make up the Great Miami River Watershed. These results provide further evidence that PFAS compounds are a growing challenge to our region. A strategic roadmap for dealing with the presence of these chemicals in our natural water is needed to help address this challenge. The issue of PFAS toxicity in treated drinking water, as well as natural waters, has gained worldwide attention in recent years. For background information on PFAS read MCD blogs:
