PATTERN-DRILLED SOILS/UST REMEDIATION
Torrent has been instrumental in the development of pattern drilling, a highly efficient method of remediation for sites with soil contamination. These are typically fuel service sites contaminated by leaking Underground Storage Tanks or product lines.
Pattern drilling entails the systematic drilling, evaluation and replacement of contaminated soil with stabilized backfill to provide substantial support for equipment and building activities while allowing for excavation for foundation footings and utility trenches.
Utilizing pattern drilling, Torrent can complete a project in a matter of weeks compared to years that may be required for other methods such as in-situ bioremediation, air sparging or vapor extraction. Such methods may only provide for partial treatment due to the complex nature of soils and the difficulty in determining pockets or hot spots requiring increased level of treatment. Pattern drilling provides the added benefit of complete removal of the contaminated soil profile and allows property owners and developers to immediately put the property to use as soon as the work is complete.
Torrent services include in-situ testing to determine actual boundaries of contamination as the remediation efforts proceed. This ensures that only the contaminated soil envelope will be removed and consequently treated. Remediation methods that require mass excavation, on the other hand, remove bulk contaminated soil mixed with uncontaminated soil, resulting in significantly higher treatment and disposal costs. In addition, Torrent can remove material as deep as 180 feet without the “benching” requirements of deep mass excavation equipment.
Pattern drilling is particularly effective in areas of tight access or potential site instability due to adjacent building structures or underground footing and obstructions. Through enhanced soil stabilizing techniques, the process has been successful in a variety of highly saturated soil conditions including large concentrations of coarse alluviums.
The environmental specialists at Torrent Resources have the field experience, OSHA HAZMAT certified personnel and technical expertise to handle a variety of soil remediation operations. Their knowledge of governmental regulations and guidelines, combined with real-world solutions, ensures a practical, cost-effective answer for site mitigation.
