Environmental consultants have been using horizontal wells for over three decades to treat virtually every contaminant that can be found in soil and groundwater, with increased efficiency when compared to traditional vertical wells. With many experienced consultants seeking to expand their remediation toolkit and new consultants entering the field looking to learn about specialized remediation techniques, it is beneficial to be aware of what types of remediation can be performed using horizontal remediation. Many consultants are surprised to find that anything that can be done via traditional vertical wells can be done via horizontal wells, oftentimes with a shorter timeline to achieve remediation goals, little to no business disruption, and a host of other benefits.
Below we’ve listed just a few of the ways that horizontal remediation wells have been used to remediate even the most challenging sites. Each category includes a link to a brief case study of a relevant project that was performed by Directional Technologies’ horizontal remediation experts:
- Injections (ISCO, ISCR, bioremedation)
- Sparging (air sparge, biosparge)
- Vapor Extraction (SVE, SSDS, passive venting, bioventing)
- Groundwater Extraction (pump and treat, hydraulic control, dewatering)
- Various Downhole In Situ Technologies (PRBs, thermal, ERH, bioreactors, sonolysis)
- …and Various Site Characterization Applications (soil sampling, remote sensing/imaging)
