          Abstract
Examines the geochemistry and transport of chromium in groundwater to determine the extent to which the composition of recharged surface water would evolve to resemble that of ambient groundwater during storage. Also studies whether redox chemistry of chromium can be used to improve removal of hexavalent chromium by coagulation. Tailored Collaboration partner: Calleguas Municipal Water District.
