Contamination from pesticides is primarily a result of the use of Caseron G and Prefix G for controlling weeds. The decomposition product 2.6-dichlorbenzamide - BAM - comes from dichlorbenil which forms part of Caseron and Prefix. Today, waterworks bore wells are analysed for many different types of pesticides and pesticides are found in relatively many waterworks bore wells.
BAM can be reduced in a pressure filter with a filter material based on activated carbon. Activated carbon is a natural product made from stone, wood, or coconut shell. An activated carbon filter can among other things remove free chlorine, pesticides, and organic solution agents.
A point source of pollution can threaten the groundwater well. To prevent contaminated water from reaching the groundwater well, an additional drilling between the polluting source and the waterworks drilling can be established.
EUROWATER has delivered mobile pressure filter plants for additional drilling projects.
