Concentrations of radium, Cambrian-Ordovician aquifer groundwater
Detailed Description
Concentrations of radium in samples of untreated groundwater from the Cambrian-Ordovician groundwater system frequently exceeded the USEPA Maximum Contaminant Level (MCL) of 5 picocuries per liter in Illinois, Iowa, and eastern Wisconsin, where wells tap deeper, older groundwater. From Stackelberg and others, 2018, "Radium mobility and the age of groundwater in public-drinking-water supplies from the Cambrian-Ordovician aquifer system, north-central USA."
