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.
Directional Technologies provided horizontal well design alterations for successful remedial results at a bulk fuels facility in North Carolina. Even at highly characterized and delineated sites, physical site restrictions can prevent the ability to implement proposed remedial designs successfully.
While many directional drilling companies exist and do an excellent job installing subsurface utilities, Directional Technologies specializes in designing, drilling, and installing horizontal remediation wells. Even for the most experienced environmental consultants, utilizing a foreign technology can be an intimidating endeavor – particularly when remedial expectations of the client are a high priority.
Targeting non-aqueous phase liquid (NAPL) hotspots with horizontal remediation wells is an effective way to enhance remediation and prevent downgradient plume migration. Groundwater contamination plumes sometimes separate into several individual zones, creating additional challenges for remediation and increasing the likelihood of off-site migration.
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 (USTs) and leaks resulting from fuel dispenser piping failures.
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.
The process of blind installation is a highly functional process that solely requires an entry point, eliminating the need for the pipe to exit on the other end of the bore. This option can significantly benefit project design, including increasing the remedial effectiveness, decreasing the remedial timeline, and providing health and safety advantages.
A property on contaminated land requires swift remediation in order to increase property value. Learn how horizontal remediation wells are used to expedite the remediation process, limit the invasiveness of vertical wells, and how your contaminated site may benefit from evaluating horizontal soil remediation techniques.
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.
