Private Drinking Water Wells


Memorandum concerning the new set back requirements

Check the Status of a Well Permit

Johnston County Environmental Health inspects, sites, and permits private drinking water wells and agricultural/irrigation in accordance with county well rules. This includes:

  • Locating the well a safe distance from possible sources of contamination;
  • Observing the grouting of the well to prevent potential avenues of contamination around the well casing;
  • Obtaining water samples to ensure that the well is producing safe, potable water.

Water Samples

Johnston County Environmental Health provides the public with a water sampling service that allows for water to be tested for several different parameters including:

    • Bacteriological
    • Chemical
    • Nitrates and Nitrites
    • Petroleum and Pesticides

A new drinking water well requires bacteriological, chemical and nitrate and nitrite samples to be taken. These samples must be free of coliform bacteria before a certificate of completion will be issued. The samples may be taken by a private lab.

For assistance in interpreting water sample results, please consult the state lab or follow the links below:
