EPA's Natural Attenuation Spreadsheet Tool

EPA's Natural Attenuation Spreadsheet Tool is a software that helps evaluate whether contaminants in soil or groundwater naturally decrease over time without active cleanup. It considers factors like contaminant properties, environmental conditions, and natural processes such as degradation or dilution. By analyzing these, the tool can determine if monitored natural attenuation (MNA) is a safe and effective way to manage contamination, potentially reducing the need for more intrusive or costly remediation efforts. It supports decision-making by providing a clear assessment of natural attenuation's capabilities at a specific site.
