In these environments the exchange of water and solute depends primarily on the hydraulic gradient between the reservoirs. We hypothesize that daily changes in river stage associated with anthropogenic water releases (such as those from a hydroelectric dam) cause anomalous mixing in the near-stream environment by creating large hydraulic head gradients between the stream and adjacent aquifer. We present field observations of hydraulic gradient reversals in a shallow aquifer. Important physical processes observed in the field are explicitly reproduced in a physically based two-dimensional numerical model of groundwater flow coupled to a simplistic surface water boundary condition. Mass transport simulations of a conservative solute introduced into the surface water are performed and examined relative to a stream condition without stage fluctuations. Simulations of 20 d for both fluctuating river stage and fixed high river stage show that more mass is introduced into the aquifer from the stream in the oscillating case even though the net water flux is zero. Enhanced transport by mechanical dispersion leads to mass being driven away from the hydraulic zone of influence of the river. The modification of local hydraulic gradients is likely to be important for understanding dissolved mass transport in near-stream aquifer environments and can influence exchange zone processes under conditions of high-frequency stream stage changes.

The University of Massachusetts Department of Geosciences and Office of the Massachusetts State Geologist were asked by the Franklin Regional Council of Governments to make an assessment of the extent, thickness and hydraulic properties of the West Charlemont aquifer located in valley fill deposits along the Deerfield River in the Town of Charlemont, Massachusetts. Previous work by Gay et al. (1974) mapped these fill deposits as a medium yield aquifer (51 gallons per minute, gpm, to 200 gpm). The purpose of this investigation is to evaluate further the potential of this medium yield aquifer as a viable groundwater resource for the Town of Charlemont. Results from six new seismic refraction surveys, three new boreholes, analysis of grain size distribution curves and a review of previous borehole logs and geophysical surveys were compiled to build a conceptual 3-dimensional visualization of the aquifer system. These data were used to make a first-order estimate of potential yield.

Surface water, groundwater, and water quality data are compiled from these local, distributed databases into a national information system. The groundwater database contains records from about 850,000 wells that have been compiled during the course of groundwater hydrology studies over the past 100 years. Information from these wells is served via the Internet through NWISWeb, the National Water Information System Web Interface. NWISWeb provides all USGS groundwater data that are approved for public release. This large number of sites is excellent for some uses, but complicates retrievals when the user is interested in specific networks, or wells in an active water- level measurement program. These "groundwater watch" web pages group related wells and data from these active well networks, and provide basic statistics about the water-level data collected by USGS water science centers for Cooperative Programs, for Federal Programs, and from data supplied to us by our customers through cooperative agreements.
