Important information about your Drinking Water
Levels of Radium, (226 + 228) in Oconto Waterworks water exceed standard
Dear Residents of the City of Oconto:
The City of Oconto’s Utility Commission has been informed by the Wisconsin Department of Natural Resources that Well # 7 located on VanHecke Ave in the City of Oconto has exceeded the Radium, (226 + 228) maximum contaminant level (MCL) based on four quarterly samples taken from Well 7 between April 2014 and March 2015. The average of these samples is 5.72 PCI/L, which exceeds the 5 PCI/L MCL for Radium, (226 + 228) as specified in ch. NR 809, Wis. Adm. Code.
Well 7 can remain in operation, but we have chosen to shut this well down, until a solution is found to keep the levels under the MCL. The City of Oconto has two other wells that will supply the City and its residents with safe drinking water.
What precautions should be taken at this time?
You DO NOT need to use an alternative (e.g. , bottled) water supply. However, if you have specific health concerns, consult your doctor.
What does this mean?
This is not an immediate risk. If it had been, you would have been notified immediately. Some people who drink water containing radium 226 or 228 in excess of the MCL over many years may have an increased risk of getting cancer. For example, if you drank 2 liters of water every day over a seventy year period with the above MCL’s you would have a one in 10,000 chance of getting cancer.
The number one priority of the City is to supply safe drinking water to its customers and will work with the D.N.R and its staff as well as other water specialists to resolve the problem as soon as possible. We will notify you when the problem is resolved.
If you have questions regarding the safety of our drinking water, please contact:
