Mobile components in a landfill may enter the groundwater and contaminate the aquifer. This risk is controlled by monitoring around the landfill. Should, however, groundwater contamination occurs due to leaching, possible remediation measures may become necessary. The treatment used depends, of course, on the substance found in the groundwater. Common substances include chlorinated hydrocarbons such as chlorinated ethenes and ethanes, chlorinated benzenes and aromatic hydrocarbons.
The usual remedial treatment consists of a pump & treat procedure. The bioscreens that we have developed are certainly also recommended in order to ensure sustainable prevention of unwanted dispersal of contaminants into surrounding areas. Bioscreens result in pollutants being degraded into harmless substances. We use both aerobic and anaerobic screens to prevent the outflow of contamination.
Screens may also be used in combination, and other options include a preceding feasibility study as well as a pilot project. For a project at a landfill in Italy, we used two bioscreens to eliminate the risk of dispersal into the surroundings. The first screen involved anaerobic degradation, subsequent to which the remaining pollutants were degraded in the second aerobic screen.
