Analysis of flow processes in fractured chalk under pumped and ambient conditions (UK)

Chalk hydraulic properties are important for groundwater models evaluating water resources. This paper provides the most comprehensive integrated geophysical and tracer analysis of Chalk to show how flow pathways change during pumping. The work has important consequences for evaluating abstraction well yields and water quality. It stimulated collaboration with Dept. Earth Science and Engineering and led to a NERC CASE studentship (McAllister), funded by Southern Water, to use technology developed by the petroleum industry coupled with these geophysical methods to develop techniques for characterising groundwater flow in Chalk to help protect Brighton’s water supply from saline intrusion.
