It has become possible during geotechnical surveys for instance, to distinguish reliably between the various grades of ferrous metals, non-ferrous metals in addition to the chemistry and concentrations of other compounds associated with anomalies at varying depths beneath the ground surface. This advance had opened the opportunity for SupaZorb to diversify its current repertoire of specialist services in remediation of hydrocarbon-contaminated soil and groundwater to other spheres of land restoration
A business unit, LeviTect, has therefore been launched within SupaZorb where our advanced geotechnologies can be harnessed for non-destructive detection and mapping of subsurface unexploded ordnance (UXOs).
LeviTect aims to meet the needs of clients in the armed forces, the arms industry and other land users across the world that are faced with high risks and liabilities accompanying uncharted explosive devices buried below the surface at active or decommissioned military weapons ranges, commercial weapons proving grounds or civil precincts in historic conflict zones.
The name LeviTect is a portmanteau composed of the bases "levitate", "technology" and "detect" to impart a quirky clue to the triplex or three-in-one means employed in delivering a service to our clients:
LevitateWith ready access to air assets, LeviTect's technologies are mounted to a rotary-wing aerial platform capable of detecting and mapping subsurface anomalies over extensive terrain in the shortest possible time span. Typically, an aerial geotechnical survey is flown at a controlled pace of 4.8 knots indicated airspeed (9km/h) at an altitude of no more than 3m above ground level (AGL) along parallel transects of 6-40m in width covering the area under survey. Airborne detection and mapping rule out any physical contact with or disturbance of UXO-contaminated terrain for reduced risk and liability to either the service provider or client. Experienced airmanship embedded with LeviTect moreover ensures the highest standards of compliance with protocols for airworthiness, flight safety and airspace management.
TechnologyLeviTect employs advanced geotechnologies capable of detecting anomalous ferrous metals of varying grades, non-ferrous metals in addition to the chemistry and concentrations of other compounds from surface-level down to 60m below ground at military weapons ranges, commercial weapons proving grounds or civil precincts in historic conflict zones. Multiple technologies including conductivity-resistivity mapping with hypsometric pseudo-colour imagery, high-resolution true-colour imagery, magnetometer readings and ground-penetrating radar scans, are combined to verify the location, orientation and nature of suspected subsurface UXOs within the limitations imposed only by the most obstructive geology, landforms and land cover. LeviTect commands the key expert skill sets for applying these geotechnologies in addition to rendering and interpreting imagery.
DetectLeviTect maps all anomalies encountered during the aerial geotechnical survey in real-time. Suspected subsurface or obscured UXOs are verified while the latitude, longitude, depth and nature (components and compounds) associated with each verified anomaly is recorded in the database of a GIS shapefile. High, medium, low and no-risk areas are zoned for the entire mapped area to indicate varying degrees of concentration or absence of UXOs. The GIS shape file with locations for UXOs and risk zones represents the first deliverable to the client. The client is furnished with a second deliverable in the form of an estimate for the cost per square unit area of choice (ft2, m2, ac, ha, km2, mi2) for the recovery and destruction of the identified UXOs and subsequent land restoration actions corresponding with the various risk zones, obstructive geology, landforms, land cover and other variables affecting cost. Armed with these deliverables, the client can confidently dispatch explosive ordnance demolition (EOD) specialists to selectively and safely recover and destroy the identified items. Alternatively, where recovery and destruction of these items are to be deferred for whatever valid reason, the estimated cost of range clearance can be entered as a contingent environmental liability in the annual financial statements of the holder or user of the UXO-contaminated land.
