Operation Water Pollution

Operation Water Pollution enables students in grades five to twelve to learn about water pollution (including what causes it, how it is cleaned up, how it can be prevented, and what they can personally do about the problem). The Operation Water Pollution program directly connects with science and social studies curricula.

Generally, sponsored Operation Water Pollution kits are sent to schools every Monday during the school year. Purchased kits are usually sent on the same dates, but teachers can request that they be sent as soon as possible and we will do our best to accommodate their request.

Notes to teachers from Tracy Webb, Science Teacher and Member of the SDWF Board of Directors:

The 11 lessons in the Operation Water Pollution program represent a comprehensive unit on water issues. Each lesson generally builds on the previous one and includes relevant, up-to-date, and well-researched fact sheets and background information. However, teachers may use any lesson on its own, or any combination, understanding that they may need to add some of the background information provided in other lessons. Every lesson can be further modified or enriched for the age and abilities of students, from grades 5 to 12. Lessons may be easily changed to reflect local conditions and situations as well, especially if teachers are/become aware and informed about their own area's water issues.

For the experimental activities, teachers may wish to substitute according to their own available supplies and/or approach to the lesson. Quantities suggested in the lesson may also be adapted as determined by the teacher.

Every lesson includes additional suggested activities and resources, along with references to other sources of information.


For lessons five and six you will need a digital TDS meter and a digital pH meter. These digital meters are included in Operation Water Pollution kits which are available from the Safe Drinking Water Foundation.

The cost of an OWP kit is $170 and includes both a digital TDS and a digital pH meter. It should be noted that each meter is guaranteed to be reusable for at least two years. Many school kits are available free of charge as a result of different sponsors. However, if there is not a sponsored kit available for your school or you want a kit right away it is best to purchase a kit.

Or, phone us at 1-306-934-0389 to pay for your kit with Visa or MasterCard.

Or, mail a cheque payable to Safe Drinking Water Foundation to:

Safe Drinking Water Foundation

Saskatoon, SK S7L 0Z6

Please remember to condition the pH meter before using it each time in your classroom by placing it in tap water, pH 7 buffer solution, pH 4 buffer solution, or KCL solution for at least 30 minutes before students use the meter. Also, please remember to calibrate the meter periodically.
