• The well casing needs to stick up above the ground, up to 12 inches but local rules vary. Your local or state health department has the information.
• There should be no gaps or spaces between the well casing and the material or soil around it.
• Make sure the casing does not have holes or cracks.
• Does the well cap fit tightly? Are any openings or vents covered by a screen?
• Be sure there is not a low area near the well where rainwater can collect. Rainwater carrying pollutants can get into well water.
• Don't keep gas, oil, weed killer, or other chemicals in your well house.
