GSI has developed the RNA Tool Kit for the Florida Petroleum Cleanup Program in cooperation with the Florida Department of Environmental Protection (DEP) and the Florida Partners in RBCA Implementation (PIRI). The model incorporates the Soil Attenuation Model (SAM) for derivation of soil-to-groundwater protection levels, and the Groundwater Natural Attenuation Model (GNAM) model (derived from BIOSCREEN) for analysis of groundwater plume attenuation rates. A new Source Mass Calculator has been added to assist in estimation of the model source term. Based on site-specific inputs, the model predicts long-term natural attenuation rates and derives source area target concentrations. These results can be used to assess the need for an active remedy or to establish the feasibility of Remediation by Natural Attenuation (RNA).

Although the software was developed for the Florida Petroleum Cleanup Program, the models used in the Florida RNA Tool Kit are generally accepted in the scientific community and can therefore can be used in any jurisdiction that allows Remediation by Natural Attenuation.

Groundwater Natural Attenuation Model (GNAM): Validated analytical groundwater transport model based on BIOSCREEN; allows comparison of several generally-accepted biodegradation algorithms.

Source Mass Calculator (SMaC): Algorithm determines the amount of contaminant mass in the source area.

Soil Attenuation Model (SAM): Calculates the amount of constituent that is being leached from the soil source into the groundwater.

Chemical/Toxicological Database: Contains all necessary chemical and toxicological parameters for numerous common constituents of concern; new compounds can be added and existing compounds edited as site conditions dictate.

User-Friendliness Enhancements: Includes comprehensive guidance manual and on-line, context-sensitive help system.

The Florida RNA Tool Kit is designed to address the following questions regarding groundwater exposure pathways at petroleum release sites:

Soil Cleanup: Is further soil removal or treatment required to protect groundwater?

RNA Time Frame: How much time is required for natural attenuation to achieve groundwater cleanup goals at this site?

Groundwater Cleanup: Is an active groundwater remedy needed? If so, how clean must the plume be before RNA will finish the job?
