ITRC document supports DNAPL source reduction

In its recently released document-DNAPL Source Reduction: Facing the
Challenge (DNAPLs-2)-the Dense Nonaqueous Phase Liquids (DNAPLs) Team of 
the Interstate Technology and Regulatory Council (ITRC) examines the 
current regulatory climate for deploying technologies to  efficiently 
treat DNAPL source zones. The report outlines the pros and cons of 
partial source removal and challenges assumptions about the 
infeasibility of removing DNAPLs from certain geological settings where 
recent advances have made significant source reduction more feasible and 
cost-effective. 

The report acknowledges the technical difficulties and uncertainties
surrounding DNAPL source zone reduction and supports further research to 
study the impacts of reduced source zone mass on groundwater quality and 
risk to human health and the environment. 

The DNAPLs Team is one of 15 currently active ITRC technical teams that 
are producing guidance documents and conducting training on the 
deployment of innovative environmental technologies. ITRC technical 
teams have produced more than 30 guidance documents, all of which are 
available online at the ITRC Web site at www.itrcweb.org. Click on 
"Guidance Documents" and  then "Dense Nonaqueous Phase Liquids" to 
download ITRC's newest product.

ITRC is a state-led group that works to overcome regulatory barriers to 
the deployment of innovative environmental technologies. ITRC 
participants come from the ranks of state regulatory agencies, federal 
agencies concerned with environmental cleanup, environmental consulting 
firms, and technology vendors. These diverse ITRC participants work 
together in technical teams to develop documents and training to help 
regulators develop a consistent and
streamlined approach for regulating innovative technologies. ITRC
products also help environmental consultants improve the way innovative 
technologies are deployed.

The ITRC Board of Directors is cochaired by Brian C. Griffin
(bcgriffin@owrb.state.ok.us <mailto:bcgriffin@owrb.state.ok.us>),
Oklahoma's Secretary of Environment, and G. Ken Taylor 
(taylorgk@dhec.state.sc.us), director of the Hydrogeology Division of 
South Carolina's Bureau of Land and Waste Management. The leader
of the DNAPLs Team is Eric Hausamann (eghausam@gw.dec.state.ny.us) of 
the New York State Department of Environmental Conservation.
