The Ontario Provincial Police (OPP) have laid criminal charges against two brothers involved in the contamination of the water supply in Walkerton Ontario in 2000. Charges were laid April 23, 2003 in Sarnia against Stan Koebel, former manager of the Walkerton Public Utilities Commission, and Frank Koebel, a Walkerton Public Utilities Commission foreman.
E Coli and Campylobacter jejuni bacteria in the water supply of the small south-western Ontario town of Walkerton resulted in the death of seven people and left hundreds sick in May 2000.
Judicial Inquiry
A judicial inquiry into the tragic water contamination in Walkerton released two reports in 2002 with hundreds of findings and recommendations. Among the findings of the inquiry were that
- proper chlorination of the Walkerton water supply could have prevented the water contamination
- Public Utilities Commision operators engaged in a host of improper operating practices
- Ontario provincial government cutbacks contributed to the tragedy.
