Current and Future Challenges in Groundwater. II: Water Quality Modeling
Publication: Journal of Hydrologic Engineering
Volume 20, Issue 1
Abstract
Groundwater quality has been a long-standing concern to water engineers and managers. Numerous studies have examined the causes of contamination, and designs for remediation systems have been developed for contamination from domestic, agricultural, and industrial activities. There is renewed interest in groundwater quality of aquifers from recent activities such as induced saltwater intrusion, hydraulic fracturing, carbon dioxide () sequestration, and deep geologic storage of nuclear waste. These topics are reviewed and discussed in this paper, focusing on the new challenges resulting from these activities. In this context, modeling flow and transport mechanisms in fractured rocks is relevant, and some recent advances in the field of fracture hydrology are highlighted. More advanced techniques of analysis, namely, fractional advection dispersion equations, are discussed in light of new interest in this topic. It is clear that advances in theory, numerical modeling, and experimentation are needed to address the complex challenges associated with groundwater quality.
