Although plant protection products are already regulated in Europe under Directive 91/414/EEC, there is increasing concern about the pollution of ground and surface water caused by point sources of pesticides, such as tank filling, spillages, faulty equipment, washing, waste disposal, and direct contamination. One tool for the reduction of pesticide point source contamination is a biological system where chemicals are bound and biologically degraded. This paper presents an offset lined system where wastewaters containing pesticide residues leach through a biomix. A pump system is provided to pump the water onto the surface of the biomix and allow it to drain under gravity, keeping the biomix wet. The analysis of residues of nine pesticides in the water, biomix, and sediment inside the tank showed the biobed to function well, with a water decontamination greater than 90%. The use of this system mitigated the potential for pollution (pesticide concentrations higher than 0.1 microg/L) of 1 km of the river system surrounding the farm.
