The Environmental Health Division routinely monitors private and public drinking water, private wells, streams and lakes, wastewater, air, soil and food for contaminants of potential environmental and public health concern. It also responds to environmental and man-made emergencies such as compromised water supplies due to chemical spills and flooding with testing needed to protect public health. Services include testing samples submitted by the general public, local health departments and state agencies.
