Research on Hydrochemical Processes at the Ground Water-Surface Water Interaction Zone
Ground water discharge to surface water is recognized as an important process governing contaminant fate and transport and ecosystem viability within watersheds. Reliable assessment of long-term patterns of the chemistry and hydrology in watersheds under the influence of ground water discharge is dependent on establishing a monitoring strategy that captures both the spatial and temporal dynamics of processes occurring at the ground water-surface water (GW-SW) interaction zone. The information gathered from this monitoring effort provides the basis for assessing the impact of ground-water discharge on human and ecosystem health and for evaluating ecosystem response to remediation and restoration activities.
