*** NOTE: We do not send Operation Water Drop or Operation Water Biology kits to schools between mid-November and the beginning of March due to freezing temperatures and their effects on the kit materials. If you order an Operation Water Drop or Operation Water Biology kit during this time period, you will receive your kit at the beginning of March. ***

Students in grades four to eight can use this kit to test their local water and control water samples for eight different components. Students will test for alkalinity, ammonia, colour, copper, pH, sulphate, total chlorine and total hardness.

The less plastic kit does not include the empty water bottle in which to collect your local water sample and it does not include the plastic cups or the disposable plastic beakers.

Students in grades nine to twelve can use this kit to test their local water and four other water samples (including control water samples) for twelve different components. Students will test for alkalinity, ammonia, arsenic, colour, copper, iron, manganese, nitrate, pH, sulphate, total chlorine and total hardness.

The less plastic kits do not include the four water bottles in which the water samples to be tested are collected (they still include the water bottle with the deionized water in it), and they do not include the plastic cups and disposable plastic beakers.

This kit, which is for students in grade five to grade 12, includes a digital TDS meter and a digital pH meter. We guarantee that these meters will work for at least two years. Students will use these meters to measure the TDS and the pH of water that they polluted and water that they filtered after doing an activity which is part of the Operation Water Pollution program.

Students in grades nine to twelve can learn about biological water treatment while conducting hands-on experiments to learn more about chlorine, chloramine, ammonia and iron.

*** NOTE: We currently do not have total hardness test materials available. We will substitute these materials with extra materials for the other tests. ***

Students in grades nine to twelve can use this kit to test their local water and four other water samples (including control water samples) for thirteen different components. Students will test for alkalinity, ammonia, arsenic, colour, copper, heterotrophic plate count, iron, manganese, nitrate, pH, sulphate, total chlorine and total hardness.
