end in death. Because of this, quality of drinking water and the water supply is so important to people. When the quality of water is impacted, concerns begin to
arise. First, there is the question of how "hard" water is. The hardness of water generally refers to the measurement of
minerals, most commonly Calcium Carbonate, in a particular measurement of water (City of Toronto, 2003). For example, Torontos drinking water has 125 mg/L or 8.8 grains of Calcium Carbonate per
Imperial gallon of water (City of Toronto, 2003). This is described as moderately hard drinking water (City of Toronto, 2003). Soft water would contain 0 to 75 gr. per Imperial
gallon; with 152 to 300 gr. per Imperial gallon making comp hard water; and 300 gr. per Imperial gallon making up very hard water (City of Toronto, 2003). Hardness levels
more than 200 mg/L are considered before a tolerable, while those in excess of 500 mg/L are unacceptable (City of Toronto, 2003). As few harmful health effects have been associated
with calcium and magnesium minerals in drinking water, there are no health standards for these minerals (City of Toronto, 2003). In addition
to minerals in water, another measurement is that of pH -- which measures acidity in water (City of Toronto, 2003). Harder water is likely to have a higher pH --
hard water is high in carbonates, making the water more alkaline (City of Toronto, 2003). However, the opposite is not good either -- water with a high degree of acidity
can corrode pipes, not to mention provide gastrointestinal problems for humans. One problem with water distribution, particularly in the United States, is
