*** NOTE: We currently do not have arsenic test materials or 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.
