Additional Information
A cluster of wells in Maryland that is influenced by mine dewatering is included in the Composite Hydrograph for the Pennsylvanian aquifer system. This cluster of wells has a major effect on the mean composite hydrograph and this effect should be taken into consideration when interpreting the hydrograph.
