Groundwater or soil contamination is present at most sites covered by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) and the Resource Conservation and Recovery Act (RCRA). Traditional technologies, such as pump-and-treat (P&T) and permeable reactive barriers (PRBs), have been used for decades to remediate such sites. In recent years, remediation strategies involving engineered nanoparticles (ENPs) such as nano zero-valent iron and titanium dioxide have been demonstrated as viable time-saving and cost-effective alternatives to traditional remediation. In addition, advances in nanotechnology-enabled assessment and monitoring methods such as nano-sensors may support more extensive, reliable, and cost effective assessment and management of remediation activities.
At the same time that applications of nano-enabled strategies and methods for environmental remediation are increasingly promising, there is a growing body of evidence linking exposure to certain nanomaterials with adverse health effects in animals at the laboratory scale. The challenge is to ensure that such applications are both safe and sustainable. Thus, scientific and technical information about toxicological properties of nanomaterials, work practices associated with the handling and use of nanomaterials, the communities in and around the contaminated sites, and other aspects of safe and proper use is needed to help environmental cleanup practitioners anticipate, recognize, evaluate, control, and confirm the safe management of potential risks associated with occupational and environmental exposures to nanomaterials.
