Project: City of Oakesdale, Oakesdale, WA
Description: Well #5; 18 inch by 487 feet, open hole, basalt formation.
Problem: Video showed heavy iron buildup, unable to see where well casing ended. Lost production gradually over 20-year period with no maintenance.
Treatment: Wire brushed well casing to 300 feet. Aqua Freed treatment, 17,000 lb of CO2.
Yield: New: 500 gpm Pre-Treatment: 200 gpm Post-Treatment: 750 gpm
Percentage Improvement: New: 50% Post-decline: 275%
Notes: City mainlines apparently very dirty. Residual CO2 pumped from well caused release of these deposits into the system.
