River Grove
NOTE: River Grove purchases water from City of Chicago which is required to test for bromochloromethane. Sample information shown below was taken by City of Chicago.
Bromochloromethane is a tap water disinfection byproduct; it is also used as an intermediate in chemical manufacturing and as a fire extinguishing agent. Disinfection byproducts in drinking water increase the risk of cancer.
