Monitored Natural Attenuation

Monitored Natural Attenuation (MNA) is an effective and sustainable remediation strategy that relies on natural processes—such as biodegradation, dispersion, dilution, and chemical reactions to reduce contaminant concentrations in soil and groundwater over time. This method is ideal for stable contamination sites where risk is low and natural attenuation is proven to be occurring. Through routine monitoring and data collection, MNA helps demonstrate that site conditions are improving without the need for aggressive intervention.

Converse provides expert Monitored Natural Attenuation guidance, helping clients determine if MNA is a viable solution for their site. Our team evaluates contaminant stability, designs monitoring plans, and works closely with regulators to meet all documentation and performance requirements. With decades of experience, Converse assesses that each Monitored Natural Attenuation plan is defensible, cost-effective, and tailored to long-term site management goals.
