Abstract
A number of water treatment processes have been investigated for their efficiencies in removing certain herbicides from freshwater samples. The herbicides used were the chlorphenoxy acids MCPA and mecoprop and the carbamates, isoproturon, linuron and chlortoluron, as these are used abundantly in Grampian Region and therefore are a potential source of contamination of potable water supplies in the region. Laboratory-based simulations of filtration treatment were set up using a number of types of activated carbon, sand, clay and peat. The results that certain types of activated carbon are very effective for removal of these herbicides from freshwaters. Clay and peat are also effective in removing the herbicides, but sand filtration proved ineffective.
