Groundwater Quality

Water-Quality Monitoring

Existing groundwater and indoor air radon-222, hereafter referred to as "radon", concentrations were aggregated and evaluated for 16 geologic units throughout the state of Pennsylvania to provide a better understanding of potential human exposure to radon.

In fractured bedrock aquifers used for domestic supply conditions can exist where contaminants such as bacteria are not filtered out by the soil. Once in the fracture system, little additional filtration takes place. The results of a synotic sampling of domestic wells in the Lower Susquehanna River basin, Pennsylvania and Maryland, showed that bacteria concentrations were higher in areas with high...
