How to Acidize the Points of a Water Well


When water wells cease to function properly, it may be necessary to acidize. The addition of acids into a well will stimulate productivity by breaking down and removing mineral deposits that may be impeding the well's proper operation. A variety of acids may be used to correct the process, depending on the materials used to construct the well. The acid is pumped into the well's bore under pressure to effect a chemical reaction with the rock to enlarge the existing points, or to create new chambers within the well.

Things You'll Need

  • Safety goggles
  • Gloves appropriate for resisting chemical spills
  • Protective clothing
  • Pump
  • Site-appropriate acid
  • Clean water (in case of accidental splash in the eyes)


  • Determine the materials used to construct your well. This includes the casing and the screen. This will dictate what type of acid should be used.

  • Determine the type of buildup that is preventing proper well operation. This may involve contacting well professionals in your area as well problems tend to stem from many of the same causes in areas with the same soil types and water source.

  • Select an acid appropriate for your well. This could be hydrochloric acid, sulfamic acid, glycolic acid or phosphoric acid. Each type will correct a specific problem and each has unique caustic properties. Know what acid you need before obtaining any.
