(JACKSON, Wyo) Teton County Public Health Department’s Environmental Health Services and the Teton Conservation District are promoting Groundwater Awareness Week. Groundwater is tapped through wells placed in water-bearing soils and rocks beneath the surface of the earth. In observance of the week, the county’s health department is urging residents with private wells to have their water tested for bacteria or other contaminants. Such testing is encouraged to be done routinely once or twice a year. Samples may be brought to the health department on Mondays and Tuesdays before 2:00 pm, and will be tested for a $15 lab fee. Teton County Environmental Health Supervisor Mike Dart points out that private household wells constitute the largest share of all water wells in the US.
