Water samples have been tested quarterly since June of 2015, when Marion Water Department received notice that our water system had a level of 6.2 pCI/L for Radium, Combined (226, 228) at source/entry point 05. This exceeded the standard, or maximum contaminant level (MCL) which is 5 pCI/L.
The Marion water supply is routinely monitored for the presence of drinking water contaminants. Quarterly testing over the course of at least one year is required to determine any correcting actions if necessary. As these test results become available, we will continue to report them here.
In the meantime, you do not need to use an alternative (e.g., bottled) water supply. However, if you have specific health concerns, consult your doctor. This is not an immediate risk. 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.
