Using compressed air to clean a groundwater well is an effective method to remove debris, sediment, biofilm, and mineral buildup. This process, known as air surging or airlifting, can help restore well performance and improve water quality. Here’s how to do it safely and effectively:
1. Gather Equipment
Air Compressor (capable of producing at least 100 PSI and a sufficient CFM for well depth)
Air Hose and Pipe (1-2 inch diameter, long enough to reach the well bottom)
Safety Gear (gloves, eye protection, hearing protection)
Well Cap Removal Tools (wrench, pliers)
Water Pump (optional) (to help remove loosened debris)
2. Prepare the Well
- Shut off the well pump and disconnect power.
- Remove the well cap and check for obstructions.
- Measure the well depth and water level to determine the correct pipe length.
3. Insert the Air Pipe
-Add the recommended cleaning treatment to the well e.g. BoreSaver Ultra C
- Lower the air pipe (or hose) to just above the bottom of the well.
- If the well has heavy sediment, position the pipe slightly higher to avoid clogging.
4. Begin Airlifting
- Connect the air hose to the compressor and slowly introduce compressed air.
- The air will create bubbles, lifting debris and water to the surface.
- Alternate between short bursts and steady airflow to agitate sediment and loosen buildup.
- If water becomes cloudy, continue until it clears.
5. Flushing the Well
- Remove the air hose and allow the well to settle.
- Pump out any remaining cloudy water until it runs clear.
- Reinstall the well cap and restore power to the pump.
6. Post-Cleaning Testing
- Run the well for a few hours to ensure proper function.
- Test water quality for clarity, bacteria, and mineral content.
Safety Tips
- Avoid excessive air pressure to prevent well casing damage.
- Work in a well-ventilated area to avoid confined space hazards.
- If the well is very deep or complex, consider hiring a professional.
