Environmental Health Division Laboratory Safeguards Wells and Septic Systems

Testing Water Quality Protects Public Health

The Environmental Laboratory safeguards the quality of private wells and septic systems. Testing water quality is crucial to maintaining public health in Will County.

We are here to help you find answers to your water quality questions. We want you to know about the quality of your water so you can make informed decisions about its impact on you and the environment in which we live. Why do we test water? A large number of human diseases, particularly those of the gastrointestinal tract are spread through contaminated water.

The EH Laboratory supports the work of the division by testing potable water for bacteria, hardness, nitrates and fluoride. The EH Laboratory is certified by the Illinois Department of Public Health and NELAC for drinking water analysis.

All samples must be brought in on ice in one of our sterile bottles which can be picked up at any health department location. Samples may be placed in a sandwich bag or container with ice cubes. Please alert staff if you have a hydrogen peroxide system or a chlorinator when picking up sterile bottles. All water from private wells should be analyzed for bacteria at least once a year.

If laboratory analysis of your well water indicates that it is unsatisfactory for drinking or cooking it will need to be disinfected. A useful description of the procedures to be followed in the disinfection of your well is contained in our Well Chlorination Instructions. This document can be downloaded and viewed below.
