Protecting Your Children’s Future As We Protect Our Own

Comprehensive Corrosion Controlprotecting-childrens-future

  • Corrosion Control Program proactively initiated by Greenville Water in the mid-1970s.
  • The corrosion inhibitor creates a protective layer on the inner surface of the pipe to prevent the leaching of metals from the pipe material into the drinking water.
  • Approved by SC DHEC when the Lead and Copper Rule was mandated by the EPA in 1994.
  • Over 700 samples are tested annually for metals at the meter.
  • Greenville Water has never exceeded the EPA’s Lead Action Level of 15 ppb, indicating that the GW distribution system has minimal lead components AND the Corrosion Control Program is working as it should.

Sampling Throughout the Distribution System

370 locations tested twice a year for 20 metals and over 20 other parameters

Additionally, Pb & Cu sampling occurs at 50 DHEC approved residences in accordance with the Lead and Copper Rule.

Proactive Pipeline Replacement Program
