Sampling locations and concentrations of Radium

Map showing sampling locations, combined Ra (226Ra + 228Ra) concentrations and estimated mean groundwater ages

Detailed Description

Sampling locations, combined Ra (226Ra + 228Ra) concentrations and estimated mean groundwater ages. Areas without grid cells are too saline for potability. (Figure 1 from Radium mobility and the age of groundwater in public-drinking-water supplies from the Cambrian-Ordovician aquifer system, north-central USA).
