LAKE IN THE HILLS – The village plans to send a message to residents this week about a recent violation of drinking water standards set by the federal Environmental Protection Agency.

However, village officials said, subsequent tests have come back clear.

In August, two of the village’s 30 test samples showed the presence of coliform bacteria, “which are naturally present in the environment and are used as an indicator that other potentially harmful bacteria may be present,” the village said in a draft notice presented at the Village Board meeting Thursday.
