A major oil storage facility (MOSF) in New York was successfully remediated in the late 1990’s using a horizontal well air sparge system.
Horizontal remediation wells (HRWs) are often most associated with accessing 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.
Horizontal drilling techniques offer significant advantages when delineating contamination, particularly on environmental projects where contamination exists in limited-access locations. Several tools can be applied to horizontal technologies to ensure the contamination at the site is well-defined, such as horizontal soil sampling and the use of down-hole sensing.
A common reason potential clients reach out to environmental consultants is because they are assessing the positives and negatives of buying or selling a contaminated property. A major concern to property owners is the ability to eventually sell their land, which is a process that is highly complicated by the presence of subsurface contamination.
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 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 that is often underutilized is the ability to use horizontal remediation wells for in-situ bioremediation of groundwater contamination – particularly through injection processes.
