The corrective action based on risk (known by its acronym as Risk-Based Corrective Action, or RBCA), have been widely accepted in the environmental sector and, therefore, responsible for site managers, regulators and consultants in all parts of the world they have applied to contaminated soils and groundwater. RBCA is a practical management approach, focused specifically on the protection of human health and the environment and also encourages the search for economic solutions in terms of cost and energy to limited financial resources are invested in higher-risk sites. A key point under the RBCA is the development of site-specific criteria for environmental cleanup after an assessment of the risks involved iteratively. It is feasible to apply this approach in different sites affected by spillage of chemical contaminants and that are located in geographically distant locations, and which is controlled by various authorities. The RBCA Tool Kit for Chemical Releases is a comprehensive software modeling and risk characterization designed to meet the requirements defined by ASTM Standard Guide for Risk-Based Corrective Action (E-2081) (ASTM Standard Guide for corrective action based on the Risk) to make assessments as Tier 1 and Tier 2 RBCA in sites with chemical spills and also perform traditional calculations for risk assessments. The software combines transport models of contaminants with tools for risk assessment purposes of calculating the risk-based line and derive standards based on the risk for a wide range of routes of exposure in soil, groundwater cleanup, water surface and air. Ease of use features and a simple GUI make it an essential tool for a site-specific calculations and serve to generic risk assessment for both simple and complex problems.
