This 15-month study was carried out to evaluate seasonal fluctuations in microbiological water quality of the Ottawa River at one station and to evaluate the potential of the coliphage as a water quality indicator. Weekly samples were collected from September 1984 to December 1985, and tested for fecal coliforms by MF and MPN procedures, E. coli MF, fecal streptococcus MF and coliphage.

"Malathion is a registered insecticide and acaricide used on a wide variety of sites including agricultural and non-agricultural sites. In 2018 (the most recent year for which data are available), over 25 000 kg of malathion was sold in Canada. Malathion may be released into surface water or soil as runoff from the application site. Malathion is not usually found in drinking water sources in Canada. Low levels of malathion have been found in several Canadian provinces. The maximum reported concentrations are well below the MAC. Malathion is rarely detected in foods"--Executive summary.
