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.

Testing Water for Coliforms

Screening for Total Coliform and E. coli as an Indicator of Water Safety

Why should my water be tested for Coliforms and E.coli? Most Coliforms are not harmful but serve as indicators of the general microbial quality of water.

Testing for the Presence of Nitrate

High levels of Nitrate in Drinking Water can be Dangerous to Health

Nitrate is naturally found in many types of food. However, high levels of nitrate in drinking water can make people sick. Exposure to excessive concentrations of nitrate can cause blue baby syndrome as a result of asphyxiation since the blood loses the ability to transport oxygen. 

Hardness Testing

Hard Water forms Deposits that Clog Plumbing

Excessive hard water forms deposits that clog plumbing and requires more soap and detergents for cleaning and laundering clothing.

Fluoride Testing

Proper Amounts of Fluoride Helps Prevent Tooth Decay

Fluoride exists naturally in water sources and is derived from the element fluorine. It is important in the prevention of tooth decay. If you use a well, fluoride levels should be checked by a laboratory. The optimal level of fluoride in the water supply are 0.9-1.2 ppm (parts per million).

2019 ADOPTION OF THE FDA FOOD CODE

2019 ADOPTION OF THE FDA FOOD CODE

In preparation for the January 1, 2019 adoption of the FDA Food Code to the Illinois Food Service Sanitation Code Will County Health Department food inspectors will be providing information throughout 2018 on the changes food service operations should expect. One significant change is the requirement for a PERSON IN CHARGE (PIC). The Person in Charge shall be the permit holder or designated by the permit holder. The Person in Charge shall be present during all hours of operations. This means that when the permit holder or manager has a day off or leaves the food service establishment they must designate a Person in Charge. The Person in Charge shall demonstrate knowledge of food borne disease prevention, the application of food safety principles and the requirements of the Food Code. Not designating a Person in Charge that is capable of fulfilling the requirements would result in a priority violation that could impact whether the food service establishment will Pass, Pass with Condition or Fail the inspection. During this transition period it is important to obtain training for staff and to implement food safety procedures that all staff are aware of and practice on a routine basis. The permit holder and management team should become familiar with the FDA Food Code. It would be advantageous to create a written standard operating procedure manual. Also, establishing a chain of command to identify the Person(s) in Charge will be one step in ensuring that inspections result with PASS.
