Steps to become a "supervised person"
Ont. Regulation 170/03 requires persons taking a chlorine residual or turbidity test to hold either a valid drinking water operator’s certificate or be a trained person (depending on the category of system). The regulation also allows persons working under the supervision of a certified operator to conduct these tests.
Requirements to become a “Supervised Person”
Operational checks for chlorine residual and turbidity must be conducted on-site and are done using portable or hand-held testing kits or devices. These tests must be performed by a certified drinking water operator, water quality analyst or a Trained Person (depending on the category of the system). Individuals who are not certified can also perform chlorine residual and turbidity tests if all of the following conditions are met:
- they were trained by a certified operator to conduct these tests (limited to the systems listed below); and
- they work under the supervision of a certified operator; and
- they immediately advise a certified operator of all test results.
Individuals who meet the criteria above are considered “Supervised Persons”.
Systems where a “Supervised Person” can conduct these tests
“Supervised Persons” can conduct chlorine residual and turbidity tests in the following drinking water systems, while working under the supervision of a certified operator:
- Municipal:
- a small municipal residential system
- a small municipal non-residential system serving a designated facility
- a large municipal non-residential system serving a designated facility
- Non-municipal:
- a small non-municipal non-residential system serving a designated facility
- a large non-municipal non-residential system serving a designated facility
- a non-municipal year-round residential system
- a non-municipal seasonal system serving a designated facility.
Steps to Become a “Supervised Person”
- Get training from a certified drinking water operator on conducting chlorine residual and/or turbidity tests. The certified operator documents this training. The ministry’s Training Manual for Supervised Persons Conducting Operational Checks may be used to train supervised persons.
- The certified operator provides supervision, including direction to the “supervised person” on testing frequency and locations. The certified operator is available by phone, pager or other means if required.
- You have obtained your Supervised Person status.
