Water Quality - Drinking Water

Newport News Waterworks is committed to providing a reliable supply of high-quality water to our customers. Your drinking water is treated and tested using state-of-the-art equipment and advanced procedures, and it meets state and federal standards for quality.

We hope that you will take a moment to view the 2013 Annual Water Quality Report. This link will take you to both the primary water quality report (for customers in Hampton, Newport News, Poquoson, lower York County and James City County) as well as the Lightfoot Well System report (for our customers in the Lightfoot area of York County) and the expanded versions of each. The expanded version lists additional test results not in the printed version. Paper copies of the report are available at all local libraries in our service area and in our walk-in customer service lobby at City Center Oyster Point (700 Town Center Drive, Newport News). A paper copy will be mailed to you upon request – just call us at (757) 926-1000.

How is our drinking water treated? Water Quality Scalled 10Waterworks treats both surface water and brackish groundwater. The surface water is pumped from our reservoirs to our treatment plants.  The water passes through screens and then aluminum sulfate (alum) and polymer are added.  These chemicals cause tiny particles in the water to cling together (coagulation), making the particles easier to remove.  After the water is clarified, ozone or chlorine (disinfection) is added to kill microorganisms such as bacteria and viruses.  The water is then sent through filters to remove any remaining particles (filtration).  Lime is added to adjust the pH, fluoride is added to prevent tooth decay in children, and zinc orthophosphate is added to control corrosion inside the pipe system.  Finally, chloramines, the secondary disinfectant, are added to maintain disinfection through the pipe system to your home or business. 

The brackish groundwater is pumped to our desalination plant located at our Lee Hall facility.  Using a process called reverse osmosis, water is forced by high pressure through membranes that can remove the salt and most other contaminants to produce very high-quality water.  The water is blended with treated surface water and sent to our customers.
