Injection The injection phase is the main disturbance of the groundwater system, as oxic, nutrient and organic matter enriched, low ionic strength water enters a commonly anaerobic, nutrient poor, brackish groundwater. The pH is commonly around neutral for stormwater and free dissolved metals are likely to adsorb to the immobile or mobile groundwater matrix near the injection well. Complexed metals and colloidal metals are more mobile and are likely to get transported until they reach areas of higher salinity (Ryan and Gschwend 1994; Bunn et al.

1999). Stormwater quality and quantity is rather variable, however, and depends on a range of parameters, but commonly occurring priority pollutants have been identified (Eriksson et al. 2007). 45 lm) deriving from natural and anthropogenic sources. TSS concentration in stormwater ranges typically from 50 to 450 mg/L with lower concentrations found in roof runoff and highest concentrations found in urban road runoff. g. g. Dempsey et al. 1993; Mikkelsen et al. 1994; Deletic and Orr 2005). While the coarser particles are likely to be settling out before use in ASR schemes, the finer, more contaminated 28 A.

Around the well (\10 m) where particulates are entrained, a so called ‘‘treatment’’ or ‘‘proximal’’ zone with highly elevated microbial activity develops. Here dissolved oxygen is eliminated in a few days, followed by nitrate reduction (Greskowiak et al. 2005; Vanderzalm et al. 2006) triggering further geochemical reactions such as degradation of organic contaminants, mineral dissolution/precipitation, sorption and pH changes that influence the quality of the recovered water (Dillon et al. 2005).
