How hard is Arvada's water?
  • Water hardness is the measure of the amount of calcium and magnesium in the water.
  • Arvada has soft to moderately hard water. It ranges from about 20 mg/L to 100 mg/L, with an average of 84 mg/L (about 5 grains per gallon).
  • Moderate hardness of the water builds scale on pipes which can help prevent corrosion of plumbing. 
  • Customers may notice white residue deposits in their humidifiers. This can be remedied by only using distilled water in the humidifier. Do not use distilled water for consumption unless directed to do so by your doctor.
  • Salespeople may try to sell you a water softener. Arvada’s water does not need to be softened. Water softeners replace calcium with sodium. Consuming this water over an extended period of time can potentially lead to heart issues. 
    • In addition, the systems need to be regularly maintained and if not, can be a source of bacteria in your drinking water.  Water softeners may lead to increased corrosion of plumbing fixtures and cause leaching of metals from the pipes in your home.
