Gross Alpha

Important Information about your Drinking Water

Level of Gross Alpha, Excl. R & U at one location in Brookfield Water Utility water exceeds standard

On February 13, 2013 (test results received on March 14, 2013) the water sample from 127 S. Moorland Road indicated the presence of Gross Alpha, Excl. R & U above the 15 PCI/L Maximum Contaminant Level (MCL) in the City’s drinking water. Further sampling on 8/27/13 confirmed the high levels of Gross Alpha, Excl. R & U. This was a violation of State and Federal Safe Drinking Water Regulations at that time. For reference, one PCI/L is one trillionth of a Curie per liter of water – so these are extremely small values.

The Wisconsin DNR requires notification of customers of said violation for a period of up to one year or until the average of samples taken over four quarters is below the MCL. Because of the one high value discovered in February, it will take time for the average to get below the MCL.

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?
There is no immediate risk. If it had been, you would have been notified immediately. Certain minerals are radioactive and may emit a form of radiation known as alpha radiation. Some people who drink water containing alpha emitters in excess of the MCL over decades may have an increased risk of getting cancer.

What has been done to correct the problem?
The Utility has already performed routine or preventative maintenance on the filtering system and made adjustments as needed. Additional water sampling confirmed maintenance activities were successful in lowering gross alpha levels to within the MCL. Compliance was achieved on June 2, 2014.
