WATER STEWARDSHIP INFORMATION SERIES Hardness in Groundwater February 2007 What is water hardness? Water hardness is primarily the amount of calcium and magnesium‚ and to a lesser extent‚ iron in the water. Water hardness is measured by adding up the concentrations of calcium‚ magnesium and converting this value to an equivalent concentration of calcium carbonate (CaCO 3 ) in milligrams per litre (mg/L) of water. The Guidelines for Canadian Drinking Water Quality Hardness divide hardness

Solar Panel The world’s energy demands increase year after year‚ while its resources are consistently being depleted in order to sustain these energy demands. These limited resources will one day be no more. A dependable source of renewable energy must be found. Currently solar energy is not efficient enough to sustain the population. However‚ the technology is constantly advancing‚ and solar energy could one day be that source. The solar cell’s roots can be traced all the way back
