Waking Up to Changing Water Quality

Abstract

During the summer and early fall of 2001, higher than usual raw and treated water manganese levels were detected at the District Municipality of Muskoka MacTier Water Treatment Plant in Ontario, Canada. This article reports on an extensive study to investigate the source of manganese and to establish factors that contributed to the sudden rise in manganese levels. The study was later expanded to determine a treatment that would control manganese concentrations at the MacTier WTP.
