Groundwater - found below the ground where it accumulated in between soil and rocks. The volume of water can range from small to very large similar to above ground creeks, rivers and lakes.
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.
To allow students to run tests on five different sources of water. Students are expected to collect three samples of water: Urban and Rural (includes Aboriginal and non-Aboriginal communities) treated waters, and a Raw Source Water.
1. One bottle contains 5 micrograms/L arsenic. Put 100 mL of water sample in the second plastic bottle with lid (not the flip top type). Water should be room temperature (20-25 degrees C).
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.
Students enter their test results for the five water samples. Students enter their results for alkalinity, ammonia, arsenic, colour analysis, copper, iron, manganese, nitrate, pH, sulphate, total chlorine and total hardness.
