Post-Closure Analysis Proves Success of Enhanced Hydrocarbon Bioremediation Using Twelve Horizontal Sparge Wells at Petroleum Products Bulk Terminal

A major oil storage facility (MOSF) in New York was successfully remediated in the late 1990’s using a horizontal well air sparge system.

The Benefits of Horizontal Air Sparging in Groundwater Remediation

Learn how using horizontal air sparging can provide benefits for groundwater remediation.

An Advanced Solution to Hydraulic Control

Due to their increased screen length and geometric compatibility, Horizontal Wells present an advanced solution to hydraulic control applications.

Let’s Talk About Money

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 we making this comparison.

HRWs Often Associated with Accessing Inaccessible Areas

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.

Difference between remediation directional drilling and utility directional drilling

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.

Exposure Pathway Elimination with Horizontal Remediation Wells

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.

Mitigate Vapor Intrusion with Access Limitations

When source-area contamination is beneath a building, a range of environmental problems arise. Contaminants can leach through the soil and impact groundwater, allowing mobility of the contamination to off-site locations. Vapor intrusion from beneath the facilities’ slab can create dangerous working conditions if vapors permeate inside the facility.

Expanding the ROI and Closing the Remedial Gap with Horizontal Remediation Wells

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.

Buying a Property on Contaminated Land

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.
