    • Enhanced Attenuation (EA) is a plume remediation strategy to achieve groundwater restoration goals by providing a “bridge” between source zone treatment and MNA and/or between MNA and slightly more aggressive methods. Natural attenuation as a viable remediation method Ross Prizzia Division of Professional Studies, University of Hawaii-West Oahu, Hawaii, USA Keywords Environment, Contamination, Groundwater, Regulations, Hazardous materials Abstract This paper describes the concept of natural attenuation and its role as a remediation by: 3.

    Methodology for estimating times of remediation associated with monitored natural attenuation / by Francis H. Chapelle [et al.] ; prepared in cooperation with the Southern Division, Naval Facilities Engineering Command and the Naval Facilities Engineering Service Center. This Natural Attenuation Software provides a screening tool for users to estimate remediation time frames for monitored natural attenuation (MNA) to lower groundwater contaminant concentrations to regulatory limits and to assist in decision making on the level of source zone treatment in conjunction with MNA, using site-specific remediation.

    monitored natural attenuation, evaluation and implementation Superfund Remedy Report found that for the period from to , MNA was selected as the sole remedy in 14% of all Superfund decision documents (e.g., record of decisions). This paper describes the development and application of a modeling system called Natural Attenuation Software (NAS). NAS was designed as a screening tool to estimate times of remediation (TORs), associated with monitored natural attenuation (MNA), to lower groundwater contaminant concentrations to regulatory limits. Natural attenuation processes that NAS models include .

2 Natural attenuation processes Natural attenuation capacity Time of remediation (TOR) can be defined as the time required to lower contaminant mass below a given threshold. Estimation of the time required for natural attenuation processes to remove contaminants from groundwater requires a mass-balance approach.
