Lead Service Line Inventory

Find more information on the Lead Service Line Inventory, due to the Public Water Supply section in October 2024, on this page.

It is the responsibility of the Public Water Supply Section to regulate public water systems within the state under the statutory authority of G.S. 130A Article 10. Public water systems are those which provide piped drinking water to at least 15 connections or 25 or more people 60 or more days per year.

There are nearly 6,000 regulated public water systems in the state. About three-fourths of the state's population lives in areas served by community water systems. Other people are served by different types of public water systems, such as workplaces, schools, parks or restaurants.

  • Inspections, investigations, and technical assistance for water systems;
  • Emergency responses and complaint investigations;
  • Source water assessment, protection, and wellhead protection;
  • Capacity development; and
  • Administration of an operating fee permit program.

In the absence of these responsibilities, the consuming public would be subjected to risks such as drinking contaminated water and having substandard drinking water facilities.
