Private Drinking Water Wells
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.
Johnston County Environmental Health provides the public with a water sampling service that allows for water to be tested for several different parameters including:
- 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.
