What has been done to reduce Lead exposure in the Northeast Water System?

To achieve Lead & Copper Rule compliance within the Rowan County Northeast Water System (NEWS), Salisbury-Rowan Utilities has implemented changes to the pH and orthophosphate at their water treatment plant (WTP): 

  • Increased the finished water pH leaving the Salisbury WTP to 7.2 - 7.4 (May 21, 2021)
  • Changed corrosion inhibitor to Zinc Orthophosphate at the Salisbury WTP (June 4, 2021)
  • Certification of Optimal Corrosion Control Treatment form for the approved treatment changes at the Salisbury-Rowan Utilities water treatment plant sent to NCDEQ.  (June 11, 2021)
  • The Chemical Booster Station achieved substantial completion and is currently being used to adjust pH levels to maintain compliance with widely varied water rates on the NEWS lines. (January 1, 2023)
