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.
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.
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.
Learn how soil vapor extraction is used, why horizontal wells are frequently chosen to implement soil vapor extraction, and how your contaminated site may benefit from evaluating soil vapor extraction.
Horizontal remediation wells offer an alternative remedial implementation approach that can help overcome challenging site conditions.
Learn why remediation of contaminated soil is important, why horizontal wells are frequently chosen for soil remediation, and how your contaminated site may benefit from evaluating horizontal soil remediation techniques.
Soil Vapor Extraction (SVE) involves the removal of vapor-phase contaminants from the vadose zone of the subsurface. The vapors are created when chemical compounds found in the subsurface volatilize.
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 become contaminated when chemicals evaporate from subsurface sources and enter the vadose zone.
Projects with high permeability soils often require fewer horizontal remediation wells due to the high radius of influence that can be achieved using Directional Technologies’ custom engineered site-specific well screen design.
