Prince William Water is aware of the September 2024 U.S. District Court ruling from California regarding fluoride in drinking water. Prince William Water purchases our drinking water wholesale from Fairfax Water and the City of Manassas, both of which are awaiting guidance from the Environmental Protection Agency and the Virginia Department of Health on this matter.

Currently, both Fairfax Water and the City of Manassas add fluoride to drinking water at or near 0.7 parts per million (ppm), following federal and state public health agency standards, including the Virginia Department of Health (VDH) and the Centers for Disease Control (CDC). Fluoride is added to drinking water to serve a public health goal to decrease the occurrence and severity of tooth decay and reduce the risk of dental fluorosis.  VDH, CDC and Fairfax Water have additional information and data on fluoridation on their websites at the following:

• Virginia Department of Health
• Fairfax Water
• Centers for Disease Control & Prevention

Odors like rotten eggs or sulfur suggest bacteria in your drain or water heater. Use bleach to clear the drain. Let the cold water run. Bring a cup of cold water from the sink where you noticed the odor to another room to smell it. If the smell persists, check the water heater. Most manufacturers recommend annual water heater cleansing. Consult your manufacturer's instructions.

General guidelines for classification of waters are as follows: 0 to 17 mg/L as calcium carbonate is classified as soft; 17.1-60 mg/L as slightly hard; 61 to 120 mg/L as moderately hard; 121 to 180 mg/L as hard; and more than 180 mg/L as very hard.  

Our water is moderately hard in the East and West Systems and hard in Bull Run Mountain/Evergreen. For more information, visit our 'Water Hardness Information' page.
