The Ministry of the Environment's (MOE) Drinking Water Management Division was created to make sure that Ontarians have clean, safe drinking water. A team of drinking water inspectors is sent to local water treatment plants in cities and towns to make sure every maintenance and operation detail complies with the Safe Drinking Water Act. Along with provincial officer training, drinking water inspectors are experts in the complex process of water treatment. They are often recruited for their engineering or technical backgrounds.
When polluters fail to heed instructions to change their practices or have caused spills through potentially deliberate acts or negligence, officers might refer them to the MOE's Investigation and Enforcement Branch. Investigators gather evidence for possible convictions under Ontario's environmental laws. Some of these investigators are former police investigators or they have similar enforcement backgrounds. When there is an environmental conviction, it's an investigator who lays the charges.
