RBCA Tool Kit for Chemical Releases

Human Health Risk Assessment

  • Comprehensive modeling and risk characterization software
  • Risk-based soil and groundwater clean-up levels consistent with local regulations or requirements.
  • Expanded flexibility and additional risk and transport models

 

Overview

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 software 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.

Features

Exposure Pathway Evaluation

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 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 allows transient groundwater modeling analysis to help estimate not only how high but how soon exposure could occur.

Chem/Tox Database

Contains default physical, chemical, toxicological and regulatory parameters for 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. Preferences can be specified for using default toxicological parameters from published sources in the USA, Netherlands, and UK. Multiple database files can be customized and easily managed within the RBCA Tool Kit interface for project or location-specific applications.

User Friendly Interface

Streamlined graphical interface guides the user through the RBCA evaluation process. Features include convenient unit selection and conversions, importing and exporting, and report printing options. The complete user's manual, including risk and fate and transport model equations, is available on-line via context sensitive help buttons located throughout the software screens.
