There about 800,000 private domestic wells in Illinois, serving about 2 million people. When these Illinoisans have questions about their home water supply, the Water Survey’s Public Service Lab can provide answers. For a modest fee, our lab can analyze water from any Illinois well, checking for parameters including calcium, magnesium, iron, arsenic, manganese, sodium, hardness, total dissolved solids, alkalinity, color, turbidity, fluoride, chloride, nitrate, and sulfate. The lab also can test water samples from wells or households supplied by municipal water for lead.

The first step is to call the lab at 217-300-7420. A staff member will talk about your testing needs and walk you through the sample collection process.
