A Groundwater Story

Wells with high radium levels from aquifers in Wisconsin, Minnesota, Iowa, Illinois, and Missouri and the Mid-Atlantic states negatively impact drinking water and wastewater, etc.  “Na-4 mica” (via kaolinite clay) is a synthetic clay.  The synthetic clay of Professor Komarneni and his research team at PSU is cheaper (by about half) and better at removal and storage of radium (224,226,228Ra) from drinking water, groundwater, and wastewater.  Removal of Ra is via conventional ion exchange systems and/or Permeable Reactive Barriers (PRBs), and permeable clay liners.  This ceramic water filter is superior for other divalent metals (90Sr2+, Ba2+Co2+, Ni2+, Zn2+and Cu2+) – from cradle to grave
