The Wiley Rock Schoolhouse, at 603 Main St. in Wiley, Colorado, was listed on the National Register of Historic Places in 2004. [1] It was built in 1938 as a Works Progress Administration project. [2] It served as an annex to the high school and included space for agriculture classes, for a blacksmith shop, and a music room. [2]
A bathtub faucet with built-up calcification from hard water in Southern Arizona. Hard water is water that has a high mineral content (in contrast with "soft water"). Hard water is formed when water percolates through deposits of limestone, chalk or gypsum, [1] which are largely made up of calcium and magnesium carbonates, bicarbonates and sulfates.
The most familiar of these is probably the presence of calcium (Ca 2+) and magnesium (Mg 2+) that interfere with the cleaning action of soap, and can form hard sulfate and soft carbonate deposits in water heaters or boilers. [13] Hard water may be softened to remove these ions. The softening process often substitutes sodium cations. [14]
Degrees of general hardness (dGH or °GH) is a unit of water hardness, specifically of general hardness. General hardness is a measure of the concentration of divalent metal ions such as calcium (Ca 2+) and magnesium (Mg 2+) per volume of water. Specifically, 1 dGH is defined as 10 milligrams (mg) of calcium oxide (CaO) per litre of

Carbonate hardness, is a measure of the water hardness caused by the presence of carbonate (CO 2− 3) and bicarbonate (HCO − 3) anions. Carbonate hardness is usually expressed either in degrees KH (from the German "Karbonathärte"), or in parts per million calcium carbonate ( ppm CaCO 3 or grams CaCO 3 per litre|mg/L).
