Groundwater Remediation, Water Pollution Technologies
Welcome to Kerfoot Technologies, Inc.

If your projects require dealing with groundwater MTBE, TBA and GRO removal, there is a process more effective than pump-and-treat and air sparging.

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.

Recent Solutions

  Release of petroleum contaminants from a retail gasoline station product line in a California Central Valley town threatened an adjacent, downgradient municipal water supply well.
Contaminants:  MTBE, GRO (gasoline-range organics)
Hydrogeology:  Highly interbedded, poorly graded sand, clayey sand, silty sand, sandy silt, silt, sandy clay, lean clay; clay lens from 12 to 16 ft bgs; hard silt bed 45 to 49 ft bgs.  Hydraulic gradient 0.0002 to 0.001 feet per foot toward supply well.

Problem:  Recalcitrant MTBE following SVE/bioventing treatment of gasoline service station in southern California
Contaminants:  TPH as gasoline (TPHg), BTEX, MTBE
Hydrogeology:  Poorly-graded sand, sand with silt, discontinuous layers of silt to 100 ft below surface; fine-grained sandy silt 100 to 115 ft, occasional dense low permeable layer of silt (100 to 105 ft).  Groundwater at 100 ft below ground surface.  Hydraulic conductivity 4.9 ft/day.  Porosity 38% in saturated silt below 100 ft

Problem:  Industrial VOC spill threatened adjacent water supply well field in Ohio
Contaminants:  PCE, TCE, c-DCE, VC
Hydrogeology:  Fluvial sand and gravel deposits with discontinuous silt lenses.  Groundwater at 5 ft below ground surface.  Hydraulic conductivity 200 ft/day.  Near-surface silt lenses caused heavy rainfall perched water events.
