McHenry County Department of Health (MCDH) conducted beach water samplings at 37 licensed beaches on Thursday, May 21. All beaches tested satisfactory. Please check with beach operators to see if your local beach will be open for the Memorial Day holiday.
To prevent illness associated with swimming, all licensed beaches on the 12 lakes in McHenry County are tested every 2 weeks for E. coli throughout the summer to determine water quality. Additional and more frequent sampling is done when elevated bacterial levels are found.
Water sampling results are reported to the appropriate beach authorities. MCDH will post an advisory or closed signage for beaches with elevated E. coli results. All beach water results and locations are readily available at the MCDH webpage www.mcdh.info (click Environmental Health, Public Beaches) or call 815-334-4585.
