Positives and negatives of buying or selling a contaminated property

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.

Design Alterations for Successful Remedial Results

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.

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.

Targeting NAPL Hotspots with Horizontal Remediation Wells

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.

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.
