Well-KLEAN SOLUTIONS
Predictable, Long-Lasting Water Well Rehab
Stop chasing short-term fixes. The Well-KLEAN® process restores production, improves water quality, and slows declining specific capacity using science-based, non-destructive methods.
Key Outcomes
-
Recover lost production
-
Improve water quality & consistency
-
Extend well life and reduce rehab frequency
-
Minimize downtime and long-term costs
Why Wells Lose Capacity Over Time
Most wells don’t fail overnight—they slowly become less productive, more expensive to operate, and harder to keep in compliance.
The core issue is usually not just “scale” or “age.” It’s the interaction of:
-
Biology – iron bacteria and sulfate-reducing bacteria forming biofilms and slime
-
Chemistry – minerals, metals, and corrosion products building a dense matrix
-
Operation – stagnation, intermittent use, and historic rehab methods
-
Materials – casing alloy (steel, HSLA, copper-bearing, stainless, PVC) and age
Over time, this leads to:
-
Reduced specific capacity
-
Plugged perforations and filter pack
-
Increased energy costs per gallon pumped
-
More frequent, less effective rehabs
This accelerating loss of capacity is what we refer to as Declining Specific Capacity—and it’s exactly why HCT built the Well-KLEAN® program: to reverse that trend and make outcomes predictable and durable.
Why Traditional Well Rehab Often Fails
Many conventional techniques focus on “energy” rather than controlled chemistry and biology:
-
Brush and bail
-
High-pressure jetting
-
Air bursting / surging
-
Dry ice / CO₂
-
Explosives / “fracking”
-
Strong acids (citric, phosphoric, sulfuric)
-
Polyacrylamides / polyphosphates
-
Shock chlorination
These methods can:
-
Shred and redistribute biofilms deeper into the filter pack and strata
-
Provide only short-term relief, followed by faster decline
-
Increase corrosion in steel casing and infrastructure
-
Require prolonged flushing after treatment
If biofilms and bacteria are embedded rather than removed, the well will quickly re-colonize, and production drops again—often faster than before.
The Well-KLEAN Process
The Well-KLEAN® program is designed to diagnose first, prescribe second. Not every well needs every procedure.
1. Discovery
We start by understanding the well and its environment:
-
Groundwater analysis (scaling tendency, LSI, biological risk, food sources for pathogens)
-
Casing alloy, age, and historical performance
-
Operating patterns: run time, idle time, stagnation
-
Previous rehab methods (jetting, acids, lining, etc.)
-
Known issues: coliforms, E. coli, casing damage, wire-wrap fragility
This allows us to identify whether the well is primarily impacted by biology, scale, corrosion, or a combination.
2. Preliminary Assessment & Recommendations
Using Discovery data plus HCT’s empirical database (1,000+ wells assessed), we:
-
Interpret the chemical & biological profile
-
Compare to similar wells and outcomes
-
Provide an initial recommendation and rehab strategy
3. Down-Hole Video
We then:
-
Pull the pump and perform a down-hole video inspection
-
Document well condition, perforations, biofilm, scale and structural issues
4. Video Review & Updated Scope
HCT reviews the video and refines the recommendations:
-
Confirm problem zones (upper aerobic vs lower anaerobic areas)
-
Adjust chemistry, tooling and procedures for the specific well
5. Detailed Well-KLEAN® Scope of Work
Finally, we issue a tailored Scope of Project. This may include:
-
Mechanical removal: brushes, plungers (not swabs), tremie pipe
-
Bioremediation (typically 1–3 cycles)
-
Controlled soak times with targeted chemistry
-
Plunging and agitation to liberate biofilms and deposits
-
Descaling (where scaling is present and beneficial to address)
-
Neutralization / passivation of metals
-
Zonal pumping and lifting to remove liberated materials
-
Final flushing with NSF-compliant chemistry
-
Disinfection that works with the chemistry (not against it)
-
Lay-up chemistry for wells that will sit idle
Every step is customized to your well, based on data—not a one-size-fits-all recipe.
Result: deeper cleaning, better restoration of specific capacity, and longer intervals between rehabs.
What We Need to Get Started
-
Water quality data (chemistry and any biological testing)
-
Any existing video or recent rehab history
