MODFLOW-2000 and MODPATH5 model data sets used to evaluate the effects of changes in pumping on regional groundwater-flow paths, 2005 and 2010, and areas contributing recharge to discharging wells, 1990-2010, in the vicinity of North Penn Area 7 Superfund site, Montgomery County, Pennsylvania: U.S. Geological Survey data release
A three-dimensional, groundwater-flow model (MODFLOW-2000) and a particle-tracking program 
(MODPATH5) were used to evaluate the effects of changes in pumping on regional groundwater-flow 
paths, 2005 and 2010, and areas contributing recharge to discharging wells, 1990-2010, in the vicinity 
of North Penn Area 7 …
