Key Results

A review of existing data was conducted to evaluate the occurrence and distribution of gross alpha-particle activity, gross beta-particle activity, radium, and polonium in public water (groundwater) systems in Charles County, Maryland. The study was prompted by the exceedances of the U.S. Environmental Protection Agency’s Maximum Contaminant Level for gross alpha-particle activity at five public water systems.
