Dynamic redox zoning during artificial recharge of groundwater



Reactive transport simulation of the development of redox zones below and downstream a recharge pond, Berlin. Variable infiltration rates as a result of pond floor clogging and re-developement by the site operator, and seasonal temperature changes impact the location and extent of the oxic, nitrate reducing and managnese reducing redox zones. The biodegradation of the some pharmaceutical residues, such as the analgesic compound phanazone contained in the infiltration water was found to be highly dependend on the existance of an oxic zone below the pond.
