NOTICE TO CUSTOMERS/USERS OF THE WOODHAVEN ASSOCIATION’S WATER SYSTEM
Levels of Total Radium, Above Drinking Water Standards
Our water system recently exceeded a drinking water standard on the water supplied from our Well #2 facility. Although this is not an emergency, as our customers, you have a right to know what happened, what you should do, and what we are doing to correct this situation.
We routinely monitor for the presence of drinking water contaminants. Quarterly testing results from July 2017 (5.47), November 2017 (5.34), January 2018 (5.28), and April 2018 (6.22) show that our system exceeded the standard, or maximum contaminant level (MCL), for combined radium. The standard for combined radium is 5 pico curies per liter (pCi/L). The average level of combined radium over the last year is 6 pCi/L (5.57).
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. If it had been, you would have been notified immediately.
The United States Environmental Protection Agency (EPA) sets drinking water standards and has determined that Radium 226 and Radium 228 are of health concern at certain levels of exposure. Some people who drink water containing total radium in excess of the MCL over many years may have increased risk of getting cancer.
Woodhaven’s water system receives its supply from two wells. Well #1 is located at the Water Plant in Section 15 and is treated to reduce radium levels. In February 2018 the results from testing showed combined radium levels of 2.04 pCi/L. Well #2 is located behind the Nature Center in Section 15 and is blended with water from Well #1 during time periods when demand exceeds the capacity level of Well #1. We are currently working with the Illinois EPA to resolve the radium issue at Woodhaven and will keep you informed of our progress.
Please share this information with all the other people who drink this water, especially those who might not have received this notice directly (for example, guests, contractors, and other visitors to Woodhaven). You can do this by posting this notice in a public place or distributing copies by hand or mail.
