Introduction:
How do you remediate beneath an active airport taxiway without interfering with commercial airliners and United States Air Force cargo planes taxiing through your work area at 60 miles per hour? This was the problem facing the Department of Defense (DoD) at a site impacted with jet fuel.

To solve the problem, our long-time client, FPM Remediations, Inc., used their knowledge of horizontal biosparging wells to design a un

To avoid costly business interruption and site disturbance, Ganesh Kurse with G & RK Consulting Associates, recommended a non-invasive remedial approach by installing horizontal ozone sparge wells with directional drilling techniques.

Although horizontal ozone sparging wells were a new remedial technology to G & RK and the State of Alabama’s underground storage tank (UST) remediation program, this alternative method of remediation system construction addressed a

Roadway intersections within urban settings are arguably some of the most challenging areas for subsurface remediation.

Many consultants tasked with remediation of challenging sites such as these become frustrated by the inability of a vertical remediation system to influence the area of concern and/or they are anxious that they will not efficiently bring their clients’ sites to closure.

A question commonly posed to Directional Technologies from our environmental consulting clients: “Can one horizontal well be designed for more than one remedial application?” The answer is “yes.”

Horizontal wells are utilized for many diverse remedial methods: air/oxygen/ozone sparge, soil vapor extraction (SVE), multiphase extraction (MPE), in-situ chemical oxidation (ISCO) injection, bio-amendment injection, thermal remediation, hydraulic control, and more.&n

“Taking time to properly plan and execute a horizontal drilling and utility installation project can save client’s monetarily by avoiding road closures and other costly delays typical with trenching,” said Mike Bertram of Directional Technologies. “We know that  Directional Technologies has the right personnel in place and they are using the best horizontal drilling practices to succeed with any challenging utility installation projects, like the one her

So your remediation project is moving towards a choice of remedy, whether it involves Dual Phase Extraction, Total Phase Extraction, Biosparging, Soil Vapor Extraction (SVE), Air Sparge (AS), or Chemox Delivery, or any combination of the above. Now, the concept of horizontal remediation wells (HRW’s) for your site seems intriguing.

So what do you need to consider before proposing a Horizontal Remediation Well system for your site?  

Here are the things you need to c

Biosparging technology can be further enhanced when applied through Horizontal Remediation Wells. Since horizontal well systems typically have 4 to 10 times more screen footage in contact with the contaminated media than vertical systems, Horizontal Biosparge Wells can inject much greater volumes while maintaining the same low flow rates. This, in turn, leads to more rapid increases in dissolved oxygen and aerobic biodegradation. In addition, these larger injection volumes have proven HBS wel

This is a comparison of a Horizontal Remediation System and a Verticle Well System at a theoretical site with an area of 388,800 ft²   where with a Radius of Influence (ROI) of 20 feet, 12 Horizontal Remediation Wells, depending on plume geometry, can cover the same area as 243 vertical wells with the same ROI per well. Not only would surface infrastructure and operations be undisturbed during a horizontal w
