The naturally occurring self-purification process at the Boyne River site is monitored. Experiments at several creeks and rivers in GTA area that induced the self-purification process are provided. As a result, the concentration of polluting agents in the water decreases up to 100 % depending on the site and pollutants.3 pagesChemical Physicstext
