WOODSTOCK – McHenry County Department of Health conducted beach water samplings at 37 licensed beaches on Wednesday, May 21. All beaches are open for the Memorial Day weekend.
To prevent illness associated with swimming, all licensed beaches on the 13 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 http://www.mcdh.info (click Environmental Health, quick links, “beach testing results”) or call (815) 334-4585.
