Private Wells and Cisterns
MCPH recommends private wells be tested seasonally for bacteriological contaminants.
The Coliform test will show whether or not your well or cistern water contains bacteria.
If polluted groundwater is consumed, it could cause illness. Groundwater pollution can be caused by seepage through landfills, failed septic tanks, underground fuel tanks, fertilizers and pesticides, as well as runoff from urban areas. Testing your water ensures the health of you and your family.
