Problem: Well manifold and mainline (well #1 to well #3) plugged with iron bacteria and slime. Low flow rate of 32 gpm.
Treatment: Injected C02 with maximum flow from well #1.
Yield: Pre-treatment flow was 32 gpm; post-treatment flow was 114 gpm
Percentage Improvement: 256% (maximum pump capacity)
Notes: Residual C02 pumped from wells has cleaning effect on mainline pipe system.
Well Description: Groundwater extraction wells; 6 and 8 inch wells in sand/gravel formation. Typical 5 to 10 feet of stainless screen.
Problem: Landfill built without liner over an aquifer.
Treatment: Acid treatment, minimal effectiveness and short life between treatments continued production decline.
|Well #2||Well #3||Well #4||Well #22|
|Pre-Treatment||14 gpm||8 gpm||19 gpm||47 gpm|
|Post-Treatment||39 gpm||25 gpm||31 gpm||82 gpm|
Notes: Pilot project was very successful. WRS Inc. was awarded 21 additional well treatments from the Landfill.
