Iron(II) concentrations in fresh groundwater in Dutch aquifers range from absent up to 50 mg/l. Evaluation of extensive chemical data sets learned that the maximum logarithmic concentration of iron(II) in aquifers, between ± 6.5

Well field Heel, in the south east of the Netherlands, consists of a row of wells drilled in an anoxic pyrite-containing aquifer alongside a former gravel pit, which now serves as a recharge basin, where water is actively aerated. All wells are serio

Although in Europe atmospheric deposition of sulphur has decreased considerably over the last decades, groundwater pollution by sulphate may still continue due to pyrite oxidation in the soil as a result of excessive fertilisation. Inflowing groundwa

Well bore clogging is caused by accumulation of particles on the well bore. However, all abstracted groundwaters contain particles, but not all wells clog. Apparently, clogging is not caused by the mere presence of particles, but other factors are al

Heavy metals like zinc are encapsulated in ironsulphide minerals (Pyrite). Nitrate addition to soils may change the environmental conditions so that the ironsulphides can be oxydized, which increases the mobility of zinc. The oxidation process in a s
