Lisa A Senior
Lisa Senior is a hydrologist with the USGS Pennsylvania Water Science Center and has been involved with both groundwater and surface-water investigations since 1986, becoming Project Chief for numerous studies in Pennsylvania since 1988.
Recent Studies
- Baseline surveys of groundwater quality in and near areas of Marcellus Shale gas development
- Evaluations of naturally occurring radionuclides, trace elements, and methane in groundwater
- Effects of land use on groundwater and surface-water quality
- Modeling of surface-water quality
- Characterization of fractured-rock hydrogeology of the Newark Basin to support contaminant delineation, monitoring, and remedial management in southeastern Pennsylvania

Science and Products
Groundwater-level trends and forecasts, and salinity trends, in the Azraq, Dead Sea, Hammad, Jordan Side Valleys, Yarmouk, and Zarqa groundwater basins, Jordan
Changes in groundwater levels and salinity in six groundwater basins in Jordan were characterized by using linear trends fit to well-monitoring data collected from 1960 to early 2011. On the basis of data for 117 wells, groundwater levels in the six basins were declining, on average about -1 meter per year (m/yr), in 2010. The highest average rate of decline, -1.9 m/yr, occurred in the Jordan Side
