Water Quality in the State of Arizona
Water quality in Arizona is governed by the Arizona Department of Environmental Quality. Arizona has relatively hard water. With only 7 inches of annual rainfall in the Phoenix metro area, surface water cannot be solely relied on. Most of the water for public use comes from the Colorado River and groundwater sources known as aquifers. Groundwater is extracted from the Black Mesa and Navajo aquifers, using wells. Depending on the location and depth of the well, the water hardness in these aquifers can range from 200-10,000 PPM. This explains why almost every region in Arizona has very hard water.
Arizona Water Hardness by City
Bullhead City has the hardest water in the state with 619 PPM. The majority of AZ cities have a hardness level of between 210-350 PPM. The most populous Arizona city, Phoenix, has a hardness level of 230 Parts Per Million. Tucson has a water hardness level of 211 PPM, and Chandler's water is 292 PPM. The city of Sierra Vista has a water hardness level of 140 PPM, while this is the lowest in the state, it is still considered hard, based on the USGS water hardness table.
For more information on water hardness in specific Arizona cities, please see the table below.
PPM = Parts Per Million
mg/L = Milligrams Per Liter
gpg = Grains Per Gallon
Mining and Water Hardness
The mining of Copper has been a major industry for the state of Arizona since the 19th century. As of 2006, Arizona was listed as the top copper producer in the United States. Copper mining also produces gold, silver, lead, and molybdenum metal as a byproduct. Arizona is also the nation's second-largest producer of Molybdenum metal. Other industrial minerals used in construction, such as limestone, sand, gravel, gypsum, and clay, are found in abundance in Arizona. The water used in the mining industry is mineral-rich, with a hardness that can reach up to 10,000 PPM.
Solutions to your Water Quality Problems
Fixing your water quality issues in the state of Arizona will depend on your specific water source. It is best to test your potable water supply in order to get a better understanding of your water quality. Testing is relatively cheap. The test results will allow you to understand if your potable water has issues that need to be addressed. Common solutions to water contamination problems may include a water filtration system, a reverse osmosis system, or other whole home water treatment solutions.
A problem that almost all Arizona residents will have to deal with is hard water. One old-fashioned, inefficient, expensive, and unhealthy method to treat hard water is with a salt-based water softener. Most people don’t realize that if you’re using a water softener, you are basically removing calcium and magnesium from your drinking water and adding salt to your diet. In addition, many states are banning the use of salt-based water softeners.
Alternative water treatment solutions such as “water conditioners” have been gaining popularity in recent years because they are cheap to operate and the best eco-friendly solution for hard water. Hydropath technology, which powers the HydroFLOW water conditioners, is by far the most efficient and cost-effective eco-friendly solution to deal with hard water problems.
