Since 1980, the municipal water supply company of Karlsruhe has been using a new treatment technology for the purification of oil-polluted groundwater at one its waterworks (Durlacher Wald). This purification project has already shown great success. The water of the most polluted well is treated with ozone and infiltrated again through the contaminated ground. In the infiltration area a barricade against the polluted groundwater is built. Furthermore, the ozone treatment leads to a better biodegradation of the organic pollutants and to a biological self-cleaning process underground. Analytical data prove that this process leads to excellent groundwater quality. The water is pumped out of the other clear wells and distributed without any further treatment, even without chlorination.
