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…
As consultants continue to explore the benefits of horizontal remediation wells, they are often pleasantly surprised to learn about the unique advantages of blind installations of horizontal remediation wells. They are pleasantly surprised because it is often assumed that the…
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…
Soil vapor extraction (SVE) is one of the most effective methods to remediate certain types of subsurface contamination. Read on to learn more about how soil vapor extraction is used, why horizontal wells are frequently chosen to implement soil vapor…
Selecting the best way to implement a remediation technology is one of the most important factors that affect remediation performance. Horizontal remediation wells offer an alternative remedial implementation approach that can help overcome challenging site conditions. Read on to learn…
By Tomas Will, Sr. Environmental Scientist At a site in the southeastern US, petroleum release incidents from leaking gasoline underground storage tanks (USTs) created a very challenging hydrocarbon remediation in an urban setting. The UST leaks had resulted in…
What is Soil Vapor Intrusion and How Can it Be Prevented? The phrase “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…
