Illinois State Water Survey Public Service Laboratory - Water Testing
The PSL analyzes water samples from household taps, wells, cisterns, lakes, and ponds throughout Illinois. Tests include calcium, magnesium, iron, arsenic, manganese, sodium, hardness, total dissolved solids, alkalinity, color, turbidity, fluoride, chloride, nitrate, and sulfate. Where lead (Pb) may be a concern (older homes, especially if lead pipes or solder present), the laboratory can provide additional testing. This lead testing is available to all homeowners in the state (municipal or private well supplies). The Public Service Laboratory does not perform analyses for bacteria, pesticides/herbicides, oils, or gases.
