Bonide Annual Grub Beater does not have application restrictions regarding properties with a well. In general, we recommend that you do not apply pesticides within 10 feet of a well or cistern for extra precaution. The product label specifies: "This chemical demonstrates the properties and characteristics associated with chemicals detected in groundwater. The use of this chemical in areas where soils are permeable, particularly where the water table is shallow, may result in groundwater contamination."
