What are the standards for chemical conditioning?

The use of detergents, chlorine, acids or other chemicals in wells for the purpose of increasing or restoring yield, shall be used according to manufacturer's recommendations. Within a consolidated formation, the placement or use of packers and subsequent pressurization within the bore hole or casing while cleaning or hydrofracturing shall not damage the seal at the drive shoe. Except for disinfection and cleaning of wells, a well drilling license is required for all other chemical conditioning that alters the condition of the water well.
