Groundwater Recharge
Recharge is the process of adding water to the saturated zone of subsurface aquifers, and cannot be directly measured at most scales.

Well-Withdrawal Footprint Mapping
A simple method for mapping groundwater withdrawals at wells provides an intuitive visualization of the magnitudes by displaying an area, the 'footprint', centered on each well to represent its volumetric rate . Footprints for closely spaced wells are combined to equitably display the area corresponding to the combined withdrawals. The size of the footprints on the map are controlled by a user...
Evaluation of Radon in Groundwater and Indoor Air in Pennsylvania
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.

Hydrologic Effects of Pymatuning Earthquake
Within hours after the Pymatuning earthquake of September 25, 1998, in northwestern Pennsylvania, local residents reported wells becoming dry, wells beginning to flow, and the formation of new springs. About 120 household-supply wells reportedly went dry within 3 months after the earthquake. About 80 of these wells were on a ridge between Jamestown and Greenville, where water-level declines of as...
Bacteriological quality of groundwater used for household supply
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...
