Taste and Perception
The taste associated with Southern Nevada's water comes from a combination of chlorine used in the treatment process and a high level of naturally-occuring minerals.

Trace amounts of chlorine remain in the water while it is being delivered to the tap to keep the water and our distribution system clean. This amount is minimal (0.2-1.0 parts per million free chlorine residual in the distribution system) and poses no health risks, but it can taste a little odd if you are not used to it.

The taste of the water is not a reflection of the water's quality. Southern Nevada's water supply is among the cleanest in the world. If you don't like the taste of your tap water, try one of the following:

• If water tastes "chlorinated," leave it out overnight or boil it. Exposure to air makes the chlorine taste disappear.
• Refrigerate tap water before drinking, preferably in a glass pitcher, as plastic can provide its own aftertaste.
• Add a teaspoon or two of lemon juice to refrigerated water.
  

Home Treatment Systems
Area tap water surpasses the standards of the Safe Drinking Water Act. Unless you have a medical condition that has compromised your immune system or leaves you at higher risk for waterborne disease, you don't need a home water-treatment system. If you decide to buy a home water-treatment system, the decision should be based on taste preferences rather than water quality concerns.
