Students enter their results for the tests: alkalinity, ammonia, colour, copper, pH, sulphate, total chlorine, and total hardness. Students compare their results to the Guidelines for Canadian Drinking Water Quality.
Results: Since there is no Canadian Drinking Water Guideline for Ammonia you will compare results to the European Union limit. The standard should give a result very close to the 0.5 mg/L colour; if the colour is darker then it DOES NOT meet the guidelines.
