Monitored Natural Attenuation in Qualitative Geochemical Assessments

Monitored Natural Attenuation in Qualitative Geochemical Assessments

Monitored Natural Attenuation (MNA) has become a proven and viable approach to treat dissolved metals contamination at former industrial facilities. Following Hemmera’s recent development of a conceptual site model for metal release and attenuation, analytical results from sentinel wells indicate attenuation mechanisms are functioning and this model is consistent with field observations, offering significant time and cost savings during site closures.
