Over recent years environmental site managers, regulatory
authorities, and consultants around the world have increasingly turned
to Risk-Based Corrective Action (RBCA) for the management of
contaminated soil and groundwater. RBCA is a practical management
approach that focuses explicitly on the protection of human health and
the environment while promoting energy and cost-efficient remedies to
allow limited resources to be targeted to the most hazardous sites. A
keystone of the RBCA framework is the development of site-specific
environmental cleanup criteria following a tiered risk evaluation
approach. This approach is broadly applicable to chemical release sites
located in different geographical settings and managed under various
regulatory authorities.
The RBCA Tool Kit for Chemical Releases is a comprehensive modeling and
risk characterization software package designed to meet the requirements
of the ASTM Standard Guide for Risk-Based Corrective Action (E-2081) for
Tier 1 and Tier 2 RBCA evaluations for chemical release sites in
addition to traditional risk assessment calculations. RBCA Tool Kit for
Chemical Releases
combines contaminant transport models and risk assessment tools to
calculate baseline risk levels and derive risk-based cleanup standards
for a full array of soil, groundwater, surface water, and air exposure
pathways. The ease-of-use features and streamlined graphical interface
features of RBCA Tool Kit for Chemical Releases make it an essential tool for handling RBCA
and generic risk assessment calculations for both simple and
sophisticated problems.

Features: So What's New in RBCA Tool Kit for
Chemical Releases?
Exposure
Pathway Evaluation:
RBCA Tool Kit for Chemical Releases performs risk-based evaluation of
groundwater, surface water, surface soil, outdoor air and indoor air
exposure pathways, for residential, commercial, and user-defined receptors:
· Groundwater ingestion
· Surface water recreational contact and fish consumption
· Combined direct contact with surface soils (incidental ingestion, dermal
absorption, inhalation of vapors and particulates, and consumption of
homegrown vegetables)
· Outdoor and indoor inhalation of vapors emanating from soil or groundwater
sources.

Fate and
Transport Models:
Fate and transport models for all
exposure pathways address a wide array of chemicals, including petroleum
hydrocarbons (including TPH), metals, chlorinated solvents, pesticides, and
more. Multiple points of exposure (POEs) allow analysis of actual vs
potential points of exposure in the same run. An array of default transport
parameters provided for various soil types. F&T models within RBCA Tool
Kit for Chemical Releases include:
· Soil and groundwater source depletion
· ASTM and USEPA (SSG) outdoor air volatilization
· Johnson & Ettinger and Groundwater Mass Flux indoor air models
· ASTM soil leaching model, with decay options
· Dual-equilibrium desorption
· Point-source air dispersion
· Domenico groundwater solute transport, with decay options

Transient
Modeling Options:
In addition to steady-state air, soil,
and groundwater exposure models, the RBCA Tool Kit for Chemical Releases allows transient
groundwater modeling analysis to help estimate not only how high but how
soon exposure could occur.
Chem/Tox
Database:
The RBCA Tool Kit for Chemical Releases database contains over 600 of chemicals, including
organic solvents, petroleum hydrocarbons (including TPH fractions),
pesticides, metals, and more. The user selects the chemical of concern and
the key data loads automatically. Multiple database files can be customized
and maintained by the user for location or project-specific values within
RBCA Tool Kit for Chemical Releases.
User-friendly
Interface: Streamlined graphical interface guides the
user through the RBCA Tool Kit for Chemical Releases evaluation process. Features include convenient unit
selection and conversions, importing and exporting, and report printing
options.
Reports:
RBCA Tool Kit for Chemical Releases produces report-quality output tables of baseline risk and cleanup standards
and report-ready summary for each chemical.
Fate and Transport Models
Fate and transport models for all exposure pathways
address a wide array of chemicals, including metals and chlorinated
solvents are included in the RBCA Tool Kit for Chemical Releases. Multiple points of exposure (POEs) allow analysis of actual vs
potential points of exposure in the same run. An array of default
transport parameters is provided for various soil types.
Transient Modeling Options
In addition to
steady-state air, soil, and groundwater exposure models, the RBCA Tool Kit
for Chemical Releases allows transient groundwater modeling analysis to help estimate not only
how high but how soon exposure could occur.
Chem/Tox
Database
This extensive chemical list in RBCA Tool
Kit for Chemical Releases covers a wide
array of chemicals, including organic solvents, petroleum hydrocarbons
(including TPH fractions), pesticides, metals, and more. The user selects
the chemical of concern and the key data loads automatically. This
database can be expanded and customized by the user and for state-specific
values.
User-friendly Interface
Streamlined graphical interface guides the user
through the RBCA evaluation process. RBCA Tool Kit for Chemical
Releases' features include convenient unit
selection and conversions, importing and exporting, and options to save
and retrieve data for efficient file storage.
Reports
The RBCA Tool Kit for Chemical releases produces
report-quality output tables of baseline risk and cleanup standards and
a report-ready summary for each chemical.
