Water Quality & Hardness
Updated: 03/2024
WATER QUALITY & HARDNESS IN THE STATE OF UTAH
Water quality in Utah is governed by the Utah Department of Environmental Quality. According to the Utah Department of Environmental Quality, there are over 1,800 drinking water sources here in Utah and over 970 public drinking water systems. These systems are rated by the Division of Drinking Water (DDW) to help ensure quality.
Water in Utah is considered to be very hard. People across the state must deal with hard water daily. The state average is right around 298 PPM.
WHAT IS HARD WATER, AND HOW CAN YOU TREAT IT?
Hard water is water that contains a high concentration of dissolved minerals, primarily calcium and magnesium. It forms when water passes through deposits of limestone, chalk, or gypsum, which are made up of calcium and magnesium carbonates, bicarbonates, and sulfates.
Here is a short video that may answer some of your questions on how to treat it:
Water hardness can vary from location within a service area. If you are interested in finding out the water hardness at your property, the easiest and most affordable way to do this is to take a sample of your water to a local pool store. Many times they will do the test for you right then & there for free.
