Simulation of Contributing Areas to Selected Public Water-Supply Wellfields in the Valley-Fill Aquifers of New York State Background For effective wellhead protection, the area where water carrying potential contaminants can enter the groundwater system and flow to the supply well must first be defined, and then best management practices need to be implemented to minimize the opportunity for contamination to occur in areas defined as sources of water to the well. Determination of the sources of water and contributing areas to wells is complex because aquifers and their connection with recharge sources are heterogeneous in nature and hidden from direct observation. The major groundwater source for public supplies in upstate New York are valley-fill aquifers of glacial and post-glacial origin. Saturated coarse-grained sediments (sand...

Variations in the current pumping stresses and a planned 72-hour aquifer test provide an opportunity to characterize hydraulic connections in the basal sand and gravel aquifer through continuous monitoring of groundwater levels in selected wells.
