Illinois EPA Notifies Sauk Village Public Drinking Water Supply of Right to Know Requirements
Springfield, IL – The Illinois Environmental Protection Agency (Illinois EPA) has notified the Sauk Village public drinking water supply that there has been a confirmed detection of groundwater contamination that poses a threat of exposure to the public and is above the Illinois maximum contaminant level (MCL) prevention standard.
Sauk Village also provides finished drinking water to Candlelight Village Mobile Home Park and Weatherstone Lakes Mobile Home Park, which are secondary users.
Vinyl chloride (VC) has been detected and confirmed in finished (distributed) water at 1.68 parts per billion (ppb). This level exceeds the MCL prevention standard for vinyl chloride of 1.0 ppb. Illinois’ MCL prevention law requires treatment below 1.0 ppb.
The Environmental Protection Act requires the water supply, and any secondary users, to provide notification to its customers of this contamination by mail, email, post card, text message or telephone, within five business days of official receipt of the Illinois EPA’s notice. The public drinking water supply must provide the Illinois EPA with written proof of the notifications within seven calendar days after they are sent.
The Illinois EPA will post this press release and other appropriate notifications on its web site at: http://www.epa.state.il.us/water/drinking-water-watch/pws-well-contamination/index.html.
U.S EPA has indicated that there is no safe level of VC. Some people who ingest water contaminated with VC over long periods of time can experience adverse health effects. The factsheet containing complete health information for VC can be found on U.S. EPA’s website at: http://water.epa.gov/drink/contaminants/basicinformation/vinyl-chloride.cfm.
The Illinois Department of Public Health also provides information on vinyl chloride at: http://www.idph.state.il.us/envhealth/factsheets/vinyl-chloride.htm
This notification is required under Section 25d-3(a) of the Environmental Protection Act [415 ILCS 5/25d-3(a)], and this triggers the MCL prevention standard under Section 17.10 of the Illinois Environmental Protection Act [415 ILCS 5/17.10].
