The Jackson County Department of Public Health performs water testing  on drinking water for the detection of Coliform, E.coli bacteria and  Nitrate. This service is only available to the general public through  the Environmental Health Section of the department of Public Health. All  water samples must be collected by a qualified Environmental Health  Specialist. There is a fee for bacteria and Nitrate testing.

Arrangements can be made with Environmental Health to  have water tested for other substances such as lead and various other  minerals. There are additional charges for these tests.

Water testing services are also available for public water suppliers.  These suppliers may include but are not limited to Campgrounds, Motels,  Churches, Schools, Restaurants, Mobile Home Parks, Subdivisions,  Convenience Stores, Supermarkets, etc. Other health departments and  consultants with the Regional Office may also utilize the water testing  services.

Our laboratory offers two methods for water testing:

  1. 1. Colilert: Tests for (presence/absence) coliforms and E.coli with definitive results at 24 hours.
  2. 2. Quanti-Tray: Provides rapid and  accurate counts of coliforms and E.coli on the Standard Methods Most  Probable Number (MPN) model. Quanti-tray detects down to one organism  per 100 ml and results are available in 24 hours.

Nitrate testing

Nitrate samples are required annually by the U.S. Environmental Protection Agency (EPA).

Nitrate samples need to be placed in ice and transport to lab immediately after collection.
