*** 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 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.
