IDPH Recommends Testing of Private Water Wells Near Lake Bluffs Estates Mobile Home Park
Elevated levels of contaminant in nearby groundwater raises concerns
SPRINGFIELD - The Illinois Department of Public Health (IDPH) advises residents who obtain their drinking water from private wells near the Lake Bluff Estates Mobile Home Park formerly Rockland Mobile Home Park) in Lake Bluff to consider testing their water for contaminants. Routine testing of the Mobile Home Park's water supply wells indicates the contaminant 1,4-Dioxane could be present in nearby private wells at levels greater than Illinois' groundwater quality standard.
Residents with private wells in an area bounded by the Elgin Joliet and Eastern Railway to the north and west, Illinois Route 131 to the east, and Illinois Route 176 to the south are encouraged to have their water tested for 1,4-Dioxane by a private laboratory. Additional options include installing carbon filters or requesting a connection to the Village of Lake Bluff community water supply.
The Illinois Environmental Protection Agency (Illinois EPA) has adopted a groundwater quality standard of 0.78 parts per billion (ppb) for 1,4-Dioxane. Years of exposure to 1,4-Dioxane above 0.78 ppb may lead to an increased risk of liver cancer. The level of 1,4-Dioxane detected in the Mobile Home Park's water supply was 0.95 ppb.
For a list of laboratories certified to analyze drinking water for 1,4-Dioxane, interpretation of test results, contaminant health effects information, and recommendations for individuals who regularly consume well water, please contact IDPH by phone at (217) 782-5830 or by email at dph.tox@Illinois.gov.
For information concerning the Lake Bluff Estates Mobile Home Park community water supply, please contact Jeff Guy (IEPA) at (217) 785-8724 or via email at Jeff.Guy@Illinois.gov.
