Calgary's Water Hardness Varies Seasonally and by Location
Water Hardness Levels in Calgary
The hardness of Calgary's water varies seasonally and by location. The Bow and Elbow Rivers, the two main sources of water for the city, have different hardness levels. The Bow River water is generally softer than the Elbow River water. The hardness of the water from the two rivers also changes with the seasons. The water is typically softer during the spring and summer months when the rivers flow is higher.
What is Water Hardness?
By definition, water hardness is the total sum of molar concentrations of calcium ions (Ca 2+) and magnesium ions (Mg 2+). The units of measurement for water hardness are parts per million (ppm) or milligrams per liter (mg/l) of calcium carbonate (CaCO3). There are three main units of measurement for water hardness: * **Grains per gallon (gpg):** This is the most common unit of measurement for water hardness in the United States. One grain of hardness is equivalent to 17.1 mg/l of CaCO3. * **Milligrams per liter (mg/l):** This is the metric unit of measurement for water hardness. One mg/l of hardness is equivalent to 0.058 gpg. * **Parts per million (ppm):** This is another metric unit of measurement for water hardness. One ppm of hardness is equivalent to 1 mg/l of CaCO3.
How to Calculate Water Hardness
You can use a water hardness calculator to convert between different units of measurement. To use the calculator, enter your initial value and select the unit. Then, click on the "Calculate" button to convert the value to the desired unit.
Water Treatment in Calgary
Calgary's water treatment plants make sure that the city's drinking water is safe and of high quality 24 hours a day, 365 days a year. The treatment process includes: * **Filtration:** The water is filtered to remove particles and impurities. * **Disinfection:** The water is disinfected with chlorine to kill bacteria and other microorganisms. * **Fluoridation:** The water is fluoridated to help prevent tooth decay.
