Pesticide residues were found in more than half (56,5%) of active waterworks boreholes

While we were away, it was reported that pesticide residues were found in more than half (56,5%) of active waterworks boreholes (drilled wells used to extract drinking water in Denmark) in 2021. In 2016, pesticide residues were found in 25,2% of active boreholes. Danmarks Naturfredningsforening, who conducted the survey, predict it will be even worse in 2022.
