Definitions
  • mg/l = Milligrams per liter, same as parts per million (ppm)
  • ug/l = Micrograms per liter, also expressed as parts per billion (ppb)
  • MCL = Maximum contaminant level is the highest level of a contaminant allowed in drinking water
  • TTHM = Total Trihalomethanes
  • NTU = Nephelometric Turbidity Units is a standard measurement of cloudiness in water, more sensitive than even the human eye can see. We monitor turbidity because it is a good indicator of the effectiveness of our water filtration system. High turbidity can hinder the effectiveness of disinfectants
