Current Research Focus Areas
In New England, fractured crystalline bedrock is relied upon for water supply for domestic and public supply wells. Despite the importance of the fractured bedrock for water, we know very little about it. Where does the water come from? How much withdrawal can be sustained? Where are sources of contamination? What processes and conditons influence the water quality? These and many other fundamental questions about the bedrock water supply cannot be answered with any certainty. Our overall focus is to address these issues using a variety of approaches including GIS analyses, groundwater modeling, field testing and tracer experiments, These are our current projects:
Using GIS based analyses in evaluating spatial and temporal trends in bedrock well hydraulic characteristics and water quality;
Evaluating the occurrences and sources of high levels of manganese, arsenic, uranium and banned pesticides in bedrock drinking water wells;
Assessing temporal trends in ground water levels in Connecticut in response to global climate change;
Evaluating historical trends in salt levels in surface water and ground water in Connecticut;
Developing management approaches to sustain the water resource in fractured crystalline bedrock;
Using tracer dilution for determining fracture flow characteristics in crystalline bedrock wells.
