Kerfoot Technologies is a leader in groundwater remediation based on innovative, fast and efficient techniques.

Kerfoot Technologies is a leader in groundwater remediation and characterization equipment.  Since 1978, our guidance in serving our customers has been innovation to provide faster, more efficient and more cost-effective groundwater treatment technologies.

Our ozone chemical oxidation sparging equipment cleans contaminated soil and groundwater with minimal site disruption.  Our patented and patent-pending C-Sparger®, Perozone®, and Nanozox™ systems and processes are exceptionally effective against the most common pollutants in a wide variety of soil types.  These chemical oxidation technologies take the place of costly and time-consuming “dig-and-haul” or pump-and-treat methods.  The constant on-site supply of ozone and peroxides offers consistent contact with contaminants, as opposed to batched liquid oxidant dosing.

Site characterization needs are met with our GeoFlo® groundwater flowmeters and push-probe soil gas/soil/groundwater samplers.

Kerfoot Technologies invites you to contact us to meet your site remediation requirements.

Kerfoot Technologies, Inc. has a mission: to develop environmental tools and technologies that speed up, simplify, and reduce the cost of groundwater remediation.

Kerfoot Technologies, Inc. is an acknowledged leader in groundwater remediation and characterization equipment. Since 1978, KTI has invented and manufactured innovative instruments and methods to obtain fast, effective, accurate, and efficient results. The product line includes its microbubble air/ozone chemical oxidation systems, heat-pulse groundwater flowmeters (GeoFlo), and soil gas push-probe samplers (Macho and Hefty Systems).

KTI’s processes and systems have been used on hundreds of remediation sites in the United States, Canada, and Europe. All products and processes obtain results with minimal site disruption, low profile, and in the case of the chemical oxidation technology, rapid site closure.

Kerfoot Technologies’ patented groundwater remediation equipment and processes evolved from the original air sparge systems, into the current chemical oxidation systems using ozone (C-Sparger) and ozone/peroxide (Perozone) with air, and further to Nanozox, with the advantages of nanobubble chemistry. The pulsed injection of gaseous microbubbles of ozone was the technical breakthrough to make the process extremely effective in the remediation of hydrocarbon and chlorinated contaminants. The development of laminar Spargepoints to allow liquid coatings on the micro- to nanobubbles further enhanced the effectiveness of reaction.

Equally important as the technology we create is the quality of our staff and service support. If there is a question of treatability, we have an in-house laboratory to perform bench-scale tests. We will assist with spargewell placement design and in the set-up and use of the equipment. Once the equipment is in place, our professionals are ready to help in the evaluation and trouble-shooting of performance and equipment. From initial design to closure, Kerfoot Technologies supports its customers.

  • Comprehensive review of site characterization data, including direct groundwater flow measurement equipment, for both rental and purchase.
  • In-house treatability bench-scale testing.
  • Theoretical and empirical time to treat models.
  • Remediation system design. .
  • Remediation system setup, startup, training, diagnostics, and performance evaluation.

Innovative –Micro to Nanotechnology Success Story

Kerfoot Technologies’ innovative chemical oxidation processes and systems, which include  C-Sparger® and Perozone®, stem from our unique knowledge of oxidative microbubble and coated microbubble reactions and the use of ozone and hydroperoxides in remediation solutions.  The patented processes dramatically reduce the time, cost, and potential long-term liability of traditional clean-up methods.

First Groundwater Flowmeter

Kerfoot Technologies takes pride in being the first to introduce a commercial groundwater flowmeter to document groundwater flow patterns and rates of flow.  The GeoFlo®groundwater flowmeter is useful directly in saturated soils, or as it is more commonly used, in cased wells or boreholes.   It operates on heat-pulse infrared principles, which parallel acoustic processes.

Kerfoot Technologies also manufactures several configurations of hammer-driven push-probe systems for sampling of soil gas, water, and soil.  These systems are truly portable.  They may be used in basements, between buildings, and in the case of the Model 14 where power is not available.
