Impact/Purpose:
Overall, these results demonstrate the sensitivity of the SIP technique to both silver and zero valent iron nanoparticles and their transport in saturated porous media and in partially saturated conditions. Our results demonstrate that SIP measurements show potential for this technique in guiding the detection and remediation processes of such contaminants within the vadose zone or their detection as part of remediation schemes. Future research will consider agglomeration and longer term experimentation investigating the biogeophysical response.
Description:
Nano sized materials are prevalent in consumer goods, manufacturing, industrial processes, and remediation technologies. The intentional and accidental introduction of nanoparticles (NP) into the subsurface pose a potential risk to the environment and public health. This research begins to address the need for the development of techniques to detect their presence and transport in the subsurface. Two sets of laboratory column experiments will be presented to achieve this objective.
