As of December 1, 2016, McHenry County Department of Health will no longer be accepting routine private water samples for analysis. We do recommend that you continue to sample your private water supply for coliform bacteria and nitrates annually. There are several water laboratories located in and near McHenry County that can conduct this analysis for you. A list of these laboratories is located below for your reference. Department staff remains available to answer any questions you may have regarding your water well and/or sampling.

Our laboratory will continue to provide testing of water samples for coliform bacteria and nitrates from non-community public water supplies and newly constructed private water wells within McHenry County. A list of current laboratory services and fees are below. Should you need any additional information or wish to discuss this further, please do not hesitate to contact the Division of Environmental Health at 815-334-4585.
