Effects of water treatment on pesticides in freshwaters.

The aim of this investigation was to evaluate the effectiveness of various water treatment processes for the removal of selected pesticides from freshwaters. Of particular interest were the herbicides likely to contaminate water courses used for potable water supplies in Grampian Region. Laboratory based simulation experiments were set up to determine the removal of chlorphenoxyalkanoic acid, substituted urea and benzonitrile herbicides from freshwaters. These simulation experiments included filtration using various natural materials (sand, clay and peat) and artificial adsorbents (activated carbon and Fullers earth), jar tests using alum to simulate coagulation and flocculation processes, and chlorination. Overall, the most cost-effective and efficient treatments for removal of the herbicides tested were filtration using activated carbon and garden peat.
