Agitation can occur when the lines are turned off for repairs or when a water line breaks. The amount added is only enough to ensure that the water at your house is free of bacteria and parasites. A slight chlorine odor or no odor indicates that the chlorine is working properly as a disinfectant. Some people buy sink filters to remove the chlorine for taste reasons. This is fine, but do not leave the filtered water out too long since it no longer has its disinfecting abilities.
Cloudy water is usually the result of dissolved air in the water lines.
Air may be introduced into the lines as a result of line maintenance, line repairs, or fire-hydrant operations. The condition is usually temporary, although it may take several hours for the air to dissipate in the lines. To check if the cloudy water is due to dissolved air, fill a glass with water and leave it on a counter for a few minutes. The water should become clear again. Cloudy water of this type is safe to use.
