Horizontal wells are often associated with soil vapor extraction, air sparging, and injections due to their ability to provide access beneath buildings; however, due to their increased screen length and geometric compatibility, they present an advanced solution to hydraulic control…
The budget is always a critical driving factor for remedial decisions, so let’s talk about money. At a basic level, it is almost always less money to install one vertical well versus one horizontal well; but by which parameters are…
Horizontal remediation wells (HRWs) are often most associated with accessing seemingly inaccessible areas of a site, such as beneath active buildings, railroads, roadways, and more. Though useful in these situations, the benefits of HRWs go far beyond accessibility. Generally, we…
As consultants continue exploring the benefits of horizontal remediation wells, they are often confronted with deciphering the difference between remediation and utility directional drilling. While many directional drilling companies exist and do an excellent job installing subsurface utilities, Directional Technologies…
Physical site constraints, in combination with shallow groundwater, have led more consultants to target exposure pathway elimination with horizontal remediation wells. Gas stations are one of the most common facilities requiring a remedial response due to compromised underground storage tanks…
How do you mitigate vapor intrusion with access limitations due to source area contamination residing beneath a large commercial building? It is not uncommon that environmental remediation sites are generated from contamination spills beneath a facility. When source-area contamination is…
While horizontal drilling techniques offer substantial advantages over vertical practices in terms of physical access to the plume, a more efficient cleanup is also accomplished by expanding the radius of influence (ROI) and closing the remedial gap with horizontal remediation…
Buying a property on contaminated land requires swift remediation in order to increase property value. Read on to learn more about how horizontal remediation wells are used to expedite the remediation process, limit the invasiveness of vertical wells, and how…
Increasingly, consultants are choosing to implement a more effective bioremediation approach via horizontal injection wells. Horizontal remediation wells offer the same services as vertical wells but with notable versatilities that can significantly improve a project’s remediation efficiency. A powerful application…
Horizontal Bioremediation at a Military Base By Tomas Will, Sr. Environmental Scientist When faced with replacing a horizontal bioremediation system at a military base, a consultant was tasked with selecting the best alternative to replace the aging system. The existing…
