Losing equipment down a groundwater monitoring well is one of the most disruptive and costly events that can occur on an environmental field project. Whether it is a bladder pump, bailer, transducer, level logger, tubing, or any other downhole device that has become dislodged and fallen to the bottom of the casing — field teams have historically had no choice but to improvise. Until now, there has simply never been a purpose-built solution on the market that was fast, reliable, safe, and field-ready for exactly this situation. Fishing hooks on wire, makeshift grapples, and other improvised tools became the industry standard not because they worked well, but because nothing better existed.
That has changed with the Extraction Kit — but it is worth understanding the real costs and risks of improvised retrieval methods, because many field teams are still unaware there is now a better option:
The limitations of improvised retrieval methods
Improvised tools fail far more often than they succeed, and the consequences go well beyond simple inconvenience:
Equipment damage — Blindly lowering a hook or wire into a well casing with no visibility means working entirely by feel. This frequently results in the hook catching the wrong part of the object, inverting it, pushing it deeper into the casing, or damaging sensitive components like pump diaphragms, transducer housings, or electronic data loggers. Equipment that might have been fully recoverable is rendered unusable.
Well casing damage — Repeated blind insertion of wire, hooks, or improvised tools into a 2-inch or 4-inch casing risks scratching, scoring, or cracking the casing wall — potentially compromising the integrity of the well itself and creating a much larger remediation problem.
Personal injury — Improvised retrieval tools under tension — particularly wire and cable — can snap back unexpectedly, posing a serious laceration and eye injury risk to field personnel. Working at depth with makeshift equipment and no visibility creates unpredictable load conditions that even experienced field teams underestimate.
Wasted time and escalating costs — At $500–$1,500 per day for a two-person field crew — including labor, vehicle, and per diem — plus equipment rental, site access, and project timeline delays, the cost of a failed DIY retrieval attempt can easily reach $5,000–$10,000 before any actual solution is found. Every hour spent on an improvised method that does not work is an hour of billable project time lost.
There is now a better option
The Extraction Kit was built specifically to fill the gap that has existed in this industry for decades. Its integrated inspection camera gives your team live visual confirmation of exactly what is down the well and how it is positioned — before any retrieval attempt is made. The patented lock-off grabber head then secures the object precisely and pulls it to the surface intact.
This applies to any lost downhole equipment — not just bladder pumps. Bailers, transducers, pressure sensors, level loggers, data loggers, PVC pipe sections, tubing, and sampling devices have all been successfully recovered using the Extraction Kit. If it fell down the well, there is a good chance we can get it back.

"Stuck" and "lost" equipment are two distinct situations — and the distinction matters for choosing the right retrieval approach.
Lost equipment refers to objects that have become fully dislodged and fallen freely to the bottom of the well — a bladder pump whose safety line broke, a bailer that slipped, a transducer that detached. This is the primary scenario the Extraction Kit is designed for. Because the object is no longer under tension or wedged against the casing, the integrated camera can locate it and the lock-off mechanism can secure and retrieve it reliably.
Stuck equipment refers to objects that are lodged, wedged, or seized against the well casing under tension — for example, a pump that has swollen, corroded, or become mechanically jammed in place. The Extraction Kit may still be able to assist in these situations, particularly if the object can be freed or made loose enough to retrieve. We assess stuck-equipment situations on a case-by-case basis.
In either scenario, field teams face the same high-cost alternatives if retrieval fails: well abandonment ($8,000–$40,000) or continued loss of a productive monitoring point. Fill out our quote request form describing your situation — we will tell you honestly whether the Extraction Kit is the right tool for it. For urgent situations call us directly at (910)-218-9954.
-
Yes. The Extraction Kit is specifically engineered to recover equipment even when no safety line is present. This is one of its most important design features, as safety lines frequently break or detach — which is often the reason the equipment is lost in the first place. The integrated inspection camera allows the operator to visually locate the object at depth, and the patented lock-off mechanism secures it for retrieval regardless of whether a line is attached.
-
The Extraction Kit is designed to retrieve virtually any lost downhole equipment, including:
Bladder pumps (all major brands including QED, GEOTECH, SOLINST)
Bailers (PVC, stainless steel, all sizes)
Transducers and pressure sensors
Level loggers and data loggers
Tubing (polyethylene, stainless steel)
PVC pipe and pipe fragments
Sampling devices and probes
Broken tools and foreign objects
If you are unsure whether your specific equipment can be retrieved, fill out our quote request form with details about the object and your well — we assess each situation individually and can customize the grabber head configuration for unusual objects. You can also call us at (910)-218-9954.

Well abandonment and redrilling typically costs between $8,000 and $40,000 depending on depth, site conditions, regulatory requirements, and local drilling rates. This figure does not include the cost of replacing the lost equipment ($500–$5,000), field crew downtime while the well is out of service ($1,000–$3,000 per day), or project delays. In many cases, a single use of the Extraction Kit — either rented or purchased — costs a fraction of what well abandonment would. Most customers tell us they recovered their investment on the first retrieval.

The Problem
The Extraction Kit
-
The Extraction Kit is a patented groundwater well equipment retrieval system developed by Extraction Resources. It is the first and only tool on the market that combines a downhole HD inspection camera with a precision lock-off retrieval mechanism in a single integrated system.
Here is how a typical retrieval works:
The Extraction Kit is lowered into the well casing on a cable
The operator views the live camera feed to visually locate the lost equipment
The retrieval head is positioned around or above the object
The cable mechanism is engaged, locking the retrieval head onto the object
The equipment is pulled to the surface intact
With the right grabber head configuration for the situation, customers have been able to retrieve lost equipment like bladder pumps, bailers, and transducers in as little as a few minutes — compared to days of failed attempts and escalating costs using conventional improvised methods.
-
The Extraction Kit was purpose-built and designed for 2-inch to 4-inch well casings — the most common sizes used in groundwater monitoring and remediation wells across North America. It is also capable of operating in well casings up to 6 inches in diameter, covering virtually every monitoring well configuration your field team is likely to encounter.

The Extraction Kit is available in configurations covering retrieval depths to suit virtually any monitoring well:
Professional edition — available for rent or purchase from stock, covers retrieval depths up to 165 feet. Suitable for the vast majority of standard groundwater monitoring and remediation wells.
Ultimate edition — available for purchase, covers retrieval depths up to 165 feet with the added benefit of a self-leveling camera, on-screen depth counter, and 1080p touchscreen monitor.
Ultimate Depth edition — available for purchase as a made-to-order configuration, extends retrieval capability up to 325 feet for deep monitoring wells where standard depth is insufficient.
Fill out our quote request form with your well depth and project details and we will recommend the right configuration — or call us at (910)-218-9954.
-
Both editions are excellent options capable of handling any lost equipment retrieval challenge — the differences come down to the monitor, depth tracking, and additional functionality:
Professional Edition The Professional is our standard go-to kit for field teams and covers the vast majority of groundwater monitoring well retrieval scenarios. It features a depth reader built directly into the cabling, marked at every 3 feet, giving your team a clear and reliable read on how far down the well the kit is deployed at any point during the retrieval.
Ultimate Edition The Ultimate is our advanced edition designed for teams who want enhanced visibility and control, particularly on deeper or more complex retrievals. Key upgrades over the Professional include:
Larger monitor — a bigger display for clearer camera visibility at depth
Touchscreen interface — intuitive touchscreen control of the monitor and system functions
On-screen depth counter — a real-time digital depth reading displayed directly on the monitor so you can track exactly how far down the well you are as you lower the kit
Self-leveling function — automatically compensates for horizontal or angled positioning of the kit, which is particularly useful when the lost object is not sitting perfectly vertical at the bottom of the casing
Not sure which edition is right for your project? Fill out our quote request form with your well depth, casing size, and a description of the lost equipment — we will recommend the best fit. You can also call us at (910)-218-9954.
-
Yes. The Extraction Kit is a fully patented device and the first technology of its kind ever developed for the groundwater monitoring and remediation industry. No other product on the market combines a live integrated inspection camera with a precision lock-off retrieval mechanism in a single purpose-built system for recovering lost equipment from groundwater monitoring wells. When you use the Extraction Kit you are using a genuinely first-of-its-kind technology with no direct equivalent anywhere in the field.
Renting the Extraction Kit
-
Yes — renting directly from Extraction Resources is the most popular option for environmental consulting firms and field teams who need the kit on a project-by-project basis. We offer flexible rental terms, ship directly to your project site or office anywhere in the US and Canada, and provide full remote support throughout your rental period. Fill out our quote request form to get started — or call (910)-218-9954 for urgent field situations.
-
Most rental kits ship same day or next business day. We understand that lost equipment in a monitoring well is a time-sensitive field emergency — we prioritize fast turnaround on all rental requests. Fill out our quote request form for the quickest response, or call us directly at (910)-218-9954 for urgent situations.
-
Yes. Every rental includes remote support from our team throughout the rental period. We can walk your field team through setup, camera operation, and retrieval technique via phone or video call. For complex situations — unusual objects, extreme depths, or non-standard well configurations — we can also arrange on-site support.
-
Yes — and this is one of the most important advantages of working directly with Extraction Resources rather than renting through a third-party equipment company. Every lost equipment scenario is different. The object type, its positioning within the well, the well casing size, and the depth all affect the best retrieval approach.
A key part of our customization is the grabber head — our purpose-built retrieval attachment that slides over the inspection camera head and physically secures the lost object. We design and fabricate custom grabber heads based on the specifics of each situation. For example:
In situations where debris, broken tubing, or another object is lodged above the lost equipment, the obstruction may need to be cleared or dislodged first before the primary object can be accessed and retrieved — requiring a grabber head designed to handle both scenarios
An object with no exposed attachment point requires a different approach than one with tubing or a safety line still attached
Unusual or non-standard objects may need a fully bespoke grabber head design
When you fill out our quote request form, include as much detail as possible about the object, its estimated position, and your well specifications — this allows us to recommend or fabricate the right grabber head before the kit even ships. For urgent situations call us at (910)-218-9954.
-
The more detail you can give us upfront, the faster we can respond with an accurate quote and the right grabber head configuration for your specific situation. When you fill out our quote request form, here is what is most helpful for us to know:
Well depth — the total depth of the monitoring well from surface to bottom
Depth of the lost object — how far down the well the object is estimated to be, based on any measurements or markings available
Well location — the city, state, and site address so we can confirm shipping logistics and turnaround time to your location
Well casing size — the internal diameter of the well casing (e.g. 2-inch, 4-inch). If you are unsure, include any well construction information you have available
Type and manufacturer of the lost equipment — the make, model, and dimensions of the lost equipment if known. This is particularly important for bladder pumps and submersible pumps, as every pump model is slightly different in terms of its physical design and — critically — what the grabber head has to work with in order to secure it, especially when no safety line is present. Different pump bodies, discharge heads, and end caps present very different retrieval opportunities. Common pump brands and models we work with include:
GEOTECH pumps — including the Geotech Bladder Pump (standard 2-inch stainless steel model, 18-inch and 36-inch versions), Geotech SS Bladder Pump, and Geotech Low Flow Bladder Pump series
SOLINST pumps — including the SOLINST Model 407 Bladder Pump, SOLINST Model 408 Double Valve Pump, SOLINST Model 410 Peristaltic Pump, SOLINST Model 404 Inertial Pump, and SOLINST Interval Sampler
QED pumps — including the QED MicroPurge MP1, QED BlakPump, QED Well Wizard Bladder Pump, and QED Sample Pro Bladder Pump
Proactive Environmental pumps — including the Proactive Mega-Monsoon, Mega-Monsoon XL, Stainless Steel Mega-Monsoon XL, Monsoon, Monsoon XL, Mini-Monsoon XL, Tsunami, and Pollard Pump series — all of which fit in 2-inch and larger well casings
Grundfos / Royal Eijkelkamp pumps — including the Grundfos Redi-Flo2, Redi-Flo3, Redi-Flo4, and the rebranded Royal Eijkelkamp MP1/Redi-Flo2 submersible pumps
Waterra pumps — including Waterra Inertial Pumps, Waterra foot valves, and Waterra 12V submersible groundwater sampling pumps
Bailers — manufacturer, material (PVC or stainless steel), length, and outer diameter
Transducers and level loggers — including In-Situ Level TROLL, Solinst Levelogger, Onset HOBO Water Level Logger, and Keller series transducers
Any other downhole equipment — include the manufacturer name, model number, length, outer diameter, and any physical features at the top or bottom of the device that might provide a gripping point
If you do not know the exact model, a description of the equipment, an approximate length and diameter, and a photo if available will help us determine the right grabber head configuration before we ship
Lost or stuck — whether the object has fallen freely and is loose at the bottom of the well, or whether it is lodged, wedged, or under tension against the casing wall
Retrieval methods already attempted — what has been tried so far, how many attempts were made, and the outcome of each. This helps us understand the current position and condition of the object before we deploy
Well construction details — whether this is a standard PVC or steel cased monitoring well, an open bedrock well, a temporary well, or any other non-standard configuration. Open bedrock wells in particular present different retrieval conditions than cased wells and are important for us to know about upfront
You do not need to have all of this information to reach out — submit what you have and we will follow up with any additional questions. Fill out our quote request form to get started, or call us at (910)-218-9954 for urgent field situations.

Ultimately this comes down to customer preference — but here is how most of our customers think about it once they understand the full picture.
Renting makes sense for teams that have an immediate, one-time retrieval need and want a fast solution shipped directly to their site. We fully support this and can typically get a kit to you same or next business day anywhere in the US and Canada.
Purchasing, however, is where the real value lies — and here is why more and more of our customers are choosing to buy outright.
When you own the Extraction Kit, you always have it ready. You can take it with you proactively on any significant groundwater monitoring or remediation project as a form of insurance — because the reality is that lost equipment in a monitoring well is rarely planned for. It happens unexpectedly, often at the worst possible moment on a project. Having the Extraction Kit already on your truck or in your field kit means you are never scrambling to source a solution while your field team stands idle and your project clock is ticking.
Consider what a single lost equipment event actually costs your organization without the Extraction Kit on hand:
Equipment replacement — $500 to $5,000 to replace a lost bladder pump, transducer, or data logger
Field labor and downtime — $500 to $1,500 per day for a two-person field crew in combined labor, vehicle, and per diem costs while the team attempts improvised retrieval or waits for a solution to be sourced and shipped
Project delays — missed sampling windows, delayed deliverables, and client schedule impacts that can damage relationships and create contractual exposure
Well abandonment and redrilling — in worst case scenarios where the well cannot be cleared, abandonment and redrilling costs run $8,000 to $40,000, plus the cost of remobilizing an entire drill crew back to the site, permits, regulatory notifications, and the time lost waiting for a new well to be installed and developed before sampling can resume
The Extraction Kit purchase price is a fraction of any one of these costs — and it pays for itself entirely the first time it saves you from any of them. For environmental consulting firms, engineering companies, and government agencies running active groundwater programs, owning the Extraction Kit is not just a smart investment — it is a practical risk management decision that protects your projects, your budgets, and your client relationships.
Every purchased Extraction Kit also comes with full warranty coverage and priority hotline support — direct phone and video call access to our team whenever you need it. Whether you are in the field mid-retrieval and need real-time guidance, or troubleshooting a situation before you deploy, our team is available to walk you through it step by step. This level of dedicated support is exclusive to Extraction Kit owners.
