Home > Press > Zero Valent Iron for Soil and Water Remediation

Abstract:
The debate over nano-scale versus micro-scale zero valent iron (ZVI) has attracted the attention of leading scientists in the environmental remediation industry. As originators of ZVI permeable reactive barrier (PRB) technology, EnviroMetal Technologies and Adventus Americas join the debate, enjoying the benefit of over 20 years of global experience in field-scale ZVI applications. The news release addresses some key points made by the European Nanotechnology Gateway organisation, via their recent report entitled "Nano zero valent iron - THE solution for water and soil remediation?"

Zero Valent Iron for Soil and Water Remediation

Waterloo, Canada & Oberhausen, Germany | Posted on August 17th, 2010

The Adventus Group, a multinational remediation technology enterprise, provides a review of the Observatory NANO Focus Report 2010 on the issues surrounding nano-scale ZVI (nZVI) for treatment of contaminated water and soil.

Colleagues at our Canadian affiliate; EnviroMetal Technologies Inc (ETI) reviewed this report, available at their website European website. It presents useful information on nanoscale zero valent iron (nZVI) use in the EU. As many industry watchers will know, ETI is the originator of ZVI permeable reactive barrier (PRB) technology. The numerous challenges surrounding this technology described in the report's conclusions reinforce our opinion that while high reactivity nanoscale metals represent an intriguing development in contaminant remediation, significant questions concerning their technical performance and cost, as well as related health and safety issues, need to be answered before these particles can be considered for widespread use as a commercial remedial option.

Specific comments are summarized in a concise report available at nZVI versus ZVI. In addition to the references therein, interested readers are directed to the following sources of information concerning nZVI technology:

* US EPA Nanotechnology for Site Remediation Fact Sheet (1)
* A detailed review of a California Groundwater Resource Association meeting held in the fall of 2009 on nanotechnology in the environment (2)
* The environmental sciences and engineering center at the Oregon Graduate Institute maintains a searchable database containing several articles pertaining to nZVI (3)

On a related note, the US Interstate Technology Regulatory Council (ITRC, in preparation) will be publishing an updated PRB guidance document in the Fall of 2010, which will include a thorough discussion of PRBs for VOCs and inorganics. We will present a review of this document in an upcoming Adventus newsletter.
