Sampling Campaign

A 4-month sampling campaign has been conducted for the monitoring of three drinking water treatment plants using flow cytometry and culture-based methods to provide information related to changes in bacterial concentration according to treatments. Flow cytometry is a fast and user-friendly technique enabling bacteria quantification and viability assessment in less than 1 hour. Specific profiles regarding log-reduction of total bacteria were obtained for each treatment plant. Chlorination appeared to be the most effective by causing metabolism inactivation and nucleic acid damages. Ozonation showed a significant impact on cell activity in contrast with ultraviolet treatment which strongly affected bacterial DNA. In addition, the results showed that active bacteria quantified by flow cytometry were significantly correlated with culturable bacteria. This alternative approach appeared as gainful compared to culture methods as it greatly facilitates the diagnosis of treatment plant process for drinking water production monitoring.

Abstract The Drinking Water Surveillance Program (DWSP), developed by the Ontario Ministry of the Environment, is an assessment project based on standardized analytical and sampling protocol. This program was recently instituted in response to a series of contaminant occurrences in the St. Clair-Detroit River area of Southwestern Ontario. This paper outlines the details and goals of the program and provides information concerning micro-contaminants in drinking water at seven drinking water treatment plants in Southwestern Ontario.
