Water Quality
Overview
Water quality is becoming more and more emphasized by health regulations and the United States Environmental Protection Agency. Recently, promulgated rules make it harder for water systems to maintain compliance. However, new regulations don't necessarily mean that the water quality has changed.
  • Nitrate in excess of 10 milligrams per liter (mg/1) (as Nitrate-Nitrogen) is a health concern to infants. High nitrate water should not be used in formula for infants under six months of age. Kearney's water contains on average 1 mg/1 nitrate.
  • Fluoride is important in the development of teeth in children. The optimum fluoride concentration is 0.9 to 1.5 mg/1. Kearney's water contains 0.5 mg/1 naturally and 0.5 mg/1 is injected to achieve a target of 1.0 mg/1.
  • Chlorine is added to the water to insure that it is free of bacteria. Kearney's water contains between 0.2 and 0.6 mg/1. The maximum contaminant level for chlorine is 4.0 mg/1. Most swimming pools maintain a level of 1 mg/1 to 5 mg/1.
