  1. This test measures total hardness, i.e. the total content of calcium and magnesium ions in the water.

  2. The expression of hardness results is normally expressed as mg/l CaCO3 (calcium carbonate). This is a convention to allow the comparison of different results and does not necessarily indicate that the hardness is present in the water in only the calcium form.
