Description:
Monitored Natural Attenuation (MNA) is widely applied in the USA to control the risk associated with ground water contamination from chlorinated solvents such a tetrachloroethylene (PCE) and trichloroethylene (TCE). MNA relies on the natural processes of degradation, sorption and dilution to bring the concentrations of contaminants to acceptable levels. MNA is widely applied in the USA. Monitored Natural Attenuation (MNA) was a component of more than 20 percent of remedies implemented between 1982 and 2005 at National Priority List (NPL) sites where groundwater is contaminated (U.S. EPA, 2007). In the interval 2005 through 2008, MNA was a component of more than 18% of NPL sites where groundwater is contaminated (U.S. EPA, 2010).
