Using Horizontal Wells for Remediation

Horizontal remediation wells offer an alternative remedial implementation approach that can help overcome challenging site conditions.

Contaminated Soil Remediation

Learn why remediation of contaminated soil is important, why horizontal wells are frequently chosen for soil remediation, and how your contaminated site may benefit from evaluating horizontal soil remediation techniques.

Challenging Hydrocarbon Remediation in an Urban Setting

During site characterization, it was discovered that the initial release had not been fully remediated and that the present-day groundwater contaminant plume covered a large area. With a large area to remediate, several businesses impacted, sensitive receptors in the area, and a renewed regulatory interest in assuring that the contamination issues be resolved for good, here’s how one of our clients teamed up with Directional Technologies to implement their remedial strategy incorporating horizontal air sparge and SVE wells.

Horizontal Soil Vapor Extraction

Soil Vapor Extraction (SVE) involves the removal of vapor-phase contaminants from the vadose zone of the subsurface. The vapors are created when chemical compounds found in the subsurface volatilize.

Preventing Soil Vapor Intrusion with Horizontal Wells

Soil vapor intrusion refers to the process by which volatile chemicals move from a subsurface source into the indoor air of overlying buildings. Soil vapor can become contaminated when chemicals evaporate from subsurface sources and enter the vadose zone.

Lessons from East Palestine in Horizontal Treatability

A chemical release associated with the train derailment has garnered nationwide attention and there are some lessons from East Palestine in horizontal treatability. The incident has raised concerns over air quality and water quality in the surrounding areas of Ohio and Pennsylvania.

Horizontal Air Sparging

Horizontal air sparging is one of the most effective methods to remediate certain types of subsurface contamination.

Horizontal Remediation in High Permeability Soils

Projects with high permeability soils often require fewer horizontal remediation wells due to the high radius of influence that can be achieved using Directional Technologies’ custom engineered site-specific well screen design.

Horizontal Wells Can Eliminate Both Real and Perceived Costs

By Tomas Will, Sr. Environmental Scientist Remediation projects can often impact the property owner in unexpected ways, and horizontal wells can eliminate both real and

Alternatives To Sonic Drilling

Before breaking the news to your client that you’re going to need to involve a sonic drilling rig to install remediation wells, consider how horizontal directional drilling techniques can be used to overcome these difficult conditions.
