INNOVATIVE TECHNOLOGIES TO ASSURE HIGHLY COST-EFFECTIVE OUTCOMES
Over the years, Vector and its matrix teaming partners have developed a variety
of innovative technologies to create remarkable cost-savings and highly successful
outcomes for their clients. Vector believes in conducting investigations in a
highly focused approach spending sampling and testing funds primarily on post
remedial verification rather than on testing efforts to completely define a problem
that will ultimately be resolved through monitored natural attenuation or other
mixed bag remedies that are narrowly defined, selected and combined to resolve
only those risks that realistically need to be addressed.
Vector draws on a wide variety of highly professional consultants in the fields
of engineering, chemistry, biology, geology, hydro-geology, geo-physics, geo-morphology,
numerical modeling and risk assessment to create independent lines of evidence
that mutually support a successful and well-accepted resolution. Only those professionals
with long experience applying directly to the problem at hand are included in
each carefully managed matrix team in order to create highly cost-effective work
products for our clients.
TREATMENT TECHNOLOGIES
Over the years Vector and its teaming partners have been at the forefront of both water and soils treatment technologies as its industrial clients have sought to comply with the exponentially growing list of environmental laws and regulations. Vector was among the first to develop highly efficient air stripping processes to treat groundwaters contaminated with chlorinated organic solvents from industrial and commercial operations. Vector and one of its teaming partners (ATS, Inc.) co-invented soil vapor remediation technologies, which were later patented, to reduce the cost and time to clean up soils contaminated with volatile solvents.
Vector was also at the forefront of developing complex industrial wastewater treatment technologies designed to efficiently remove metals to extremely low levels in the effluent from industrial plating waste treatment processes, while minimizing the volumes of sludge needing disposal as a hazardous waste. Recently, Vector designed and built a groundwater treatment facility to treat PCB's and Mercury in Superfund landfill leachate for a discharge to surface waters by employing high levels of iron naturally occurring in the leachate to drive a patented co-precipitating floc that enmeshed Mercury and adsorbed PCB's to the ultra-low levels being written into the new NPDES limitations being written for these persistent bio-accumulative compounds.
GeoMorph™ PROCESS FOR SEDIMENT AND SOIL REMEDIATION
GeoMorph™ (a registered trademark of Ann Arbor Technical Services, Inc) is a process developed by Vector and its teaming partners in the last few years to address the longstanding and costly problem of removing PCB's and other PCB-like bio-accumulative compounds in river sediments and their floodplains. The root technology of this process is "geo-morphology," which is the study of landforms on the surface of the Earth, and the processes that create and shape them. Fluvial geo-morphology, a subspecialty profession, is the focused study of those landforms that are specifically created or influenced by moving water, such as rivers or streams.
The science of fluvial geo-morphology has been used to define, characterize, map, and predict depositional and erosional areas on river systems ranging in size from small streams to the Mississippi River. A fluvial geo-morphological characterization is the process of determining depositional and erosional environments within a river to understand the storage and transport of sediments through the river system. The geomorphic model of a river provides the foundation for the GeoMorph™ process by guiding the sampling, data evaluation, risk evaluation, remedial design, and remediation implementation/residuals management.
The GeoMorph™ process was developed by integrating geo-morphologic concepts and risk analysis to river environments, and combining this with a practical approach to remedial design and implementation. The GeoMorph™ process integrates three primary components: site assessment, imbedded risk review, and real-time (or near-real-time) fully validated analytical data from very carefully selected locations. GeoMorph™ is used to identify areas of sediment deposition and erosion based on stream gradient, water velocity, thalweg location, sinuosity of the stream, and morphology of the floodplain and terraces. The process identifies similar sediment morphologies and focuses sampling to characterize these units. Remedial activities can then be evaluated by narrowly focusing on the sediment/soil deposits with the greatest risk. GeoMorph™ is used to identify which sediment deposits should be removed to yield the greatest environmental benefit. It is also used to identify which deposits can be managed in-place with acceptable levels of risk. In conjunction with the remediation activities, the risk analysis is enhanced with real-time data gathering in the post-remediation verification process. During remediation activities, field observations by trained scientists and the near real-time post-remediation concentration verification process assures a successful remediation without costly contractor delays or multiple mobilizations.
GeoMorph™ has recently been demonstrated to be both highly cost-effective for our clients and well accepted by regulatory agencies on a major PCB-contaminated sediment remediation project in Wisconsin. The GeoMorph™ process is now being employed to address decades of accumulation of PCB-like toxic substances in the sediments and floodplain soils of a major Michigan river system for a confidential Fortune 100 client.
