Did you know that testing your well water for bacteria and nitrates is recommended annually? Most Barrington area residents’ drinking water comes from groundwater drawn from the shallow aquifer system. The state requires public water supplies to be tested for a wide range of contaminants on a routine basis, but there are no requirements for private wells to be tested. Residents relying on private wells are responsible for making sure their water is safe to drink.
Households with private wells are advised to test for bacteria and nitrates on an annual basis to detect these invisible, odorless contaminants. Bacteria and nitrates can result from animal or human waste or fertilizer components reaching the well water and can cause illness in humans.
BACOG, in conjunction with the Lake County Health Department laboratory, annually offers private well water testing that is fast, easy and inexpensive.
