Enhanced Natural Attenuation: Pathways to Sustainable Remediation
June 16 @ 12:00 pm – 1:30 pm
Join us for a webinar on June 16th from 12:00–1:30 p.m. EDT!
Monitored natural attenuation (MNA) of environmental contaminants in soils and groundwater relies on natural physical, chemical, and biological processes to reduce risks associated with the contamination. These in-situ, passive processes are monitored to track performance for meeting cleanup criteria over an expected timeline. Sometimes the natural processes are estimated (or observed) to not meet remedial objectives in a suitable time, so it may be appropriate to apply enhanced attenuation (EA) approaches to give the natural processes a little boost, for example, by improving degradation rates or facilitating mobility reduction. While the helping hand of EA typically requires a bit more activity than MNA, the approaches are intended to be a lighter, more sustainable approach than fully active remediation approaches, such as pump-and-treat. Seminar presenters will explore specific enhanced attenuation technologies and approaches, their associated resource demands and impacts, and methodologies for evaluating and comparing the environmental footprint of different remediation approaches—from green adsorbents to phytoremediation systems.
