Many sites with ground and/or surface water pollution
have been identified across the United States. For site characterization,
exposure and risk assessment as well as remediation monitoring, it is important
to analyze the environment for toxic contaminants at trace levels. However, this
sensing is often expensive, especially when attempting to detect ultra-trace
contaminants.
A researcher at the Biodesign Institute of Arizona State
University has developed a field-deployable sampling device for long-term,
cost-effective monitoring of ground and surface waters. It can be used in
space-restricted environments such as groundwater monitoring wells, and through
its process of concentrating contaminants from large volumes of aqueous samples,
it is able to detect contaminants at ultra-trace concentrations not previously
attainable.
This device can be used for cost-effective environmental
monitoring, tracking the progress and success of hazardous waste remediation,
and for risk and exposure assessment.
Potential Applications
- environmental monitoring
- early-warning surveillance
- tracking the progress/success of hazardous waste remediation
- risk and exposure assessment
- ground and/or surface water pollution
- ultra-trace contaminants
- early-warning surveillance
Benefits and Advantages
- cost-effective
- detects contaminants at ultra-trace concentrations not previously
attainable
- field-deployable to even space-restricted environments
- produces time-weighted average concentrations
- detects contaminants at ultra-trace concentrations not previously
