It is important to know the location of the well on the property. It’s a good idea to keep contaminants and their storage containers away from the well area. Substances like paint, motor oil, fertilizer and pesticides should be kept away from the well, pump and pressure tank at all times to avoid the water supply becoming contaminated. A homeowner should routinely visually check the well cover or cap to make sure it is securely attached and in good condition to keep insects, rodents and other pests out of the water source.
