What's New in
VERSION v.2.5? |
| |
Feature Enhancement: On the Input Parameters Summary,
any values that differ from RBCA Tool Kit default values or user specified
default values are highlighted. |
| |
Compatibility: Version 2.5 is now compatible with
Office 2007 |
|
|
Expanded Exposure Pathway Options |
| |
Groundwater
Ingestion:
Combined evaluation of risk-based exposure limits with concentration-based
regulatory limits (e.g. drinking water standards), if applicable. |
| |
Soil Direct
Contact Pathway:
Evaluation of individual or combined exposure routes. |
| |
Vegetable
Ingestion Pathway:
Evaluation of ingestion of above-ground (leafy) and below-ground (root)
vegetables for soil contact pathway. |
| |
Offsite
Indoor Air Receptors:
Evaluation of receptors who may be exposed to indoor vapors due to off-site
migration of chemicals in groundwater. |
|
|
|
User-Friendliness and Flexibility
Enhancements |
| |
Summary
Report Printing Dialog Box:
Select and print all or as many input and output screens as desired from one
convenient location. |
| |
User-Defined
Default Input Parameters:
Customize and save your own default input parameters, or revert to the RBCA
Tool Kit defaults at any time. |
| |
User-Defined
Receptor:
Specify exposure factors for any alternative human receptor in addition to
default Residential and Commercial receptors |
| |
Age-Averaging
and Sensitive Receptor Options:
Apply age-averaged exposure factors for carcinogenic (non-threshold)
compounds only and select most sensitive receptor for non-carcinogenic
(threshold) compounds. |
| |
Pathway-Specific Output for TPH:
Soil and groundwater cleanup levels for TPH mixtures are presented for each
complete exposure pathway together with results for individual chemicals of
concern. |
|
|
|
Expanded and Updated Chemical Database |
| |
Over 600
Chemicals:
Contains updated physical, chemical and toxicological values for over 600
chemicals of potential concern:
|
| |
International
Toxicological References: Users can specify preferences for using default
toxicological parameters provided from published sources in the USA, Netherlands and UK. |
| |
Stand-Alone
Chemical Database:
The
complete chemical database files is accessible and customizable by the user,
either from within the RBCA Tool Kit application or as a stand-alone utility
in its own right. The use of multiple database files for location or
project-specific applications can be easily managed from within the RBCA
Tool Kit user interface. |
|
|
|
Expanded Fate and Transport Models |
| |
Volatilization and Particulate Models:
“Q/C” soil volatilization and particulate emission model, as implemented
USEPA Soil Screening Guidance, in addition to default ASTM models. |
| |
Groundwater
Mass Flux Indoor Air Model:
Mass-balance limited model for volatilization from groundwater to indoor air.

| |
Source
Depletion:
Account for measured source zone attenuation rates when considering future
exposures. |
| |
Dual
Equilibrium Desorption Model:
Account for bi-phasic desorption of organic chemicals in evaluation of
leaching and volatilization pathways.

| |
Mass Balance
Control Options:
Option to disable mass-balance constraints for soil leaching and
volatilization models. |
|
|
|
Improved Save/Load Options for
Chemical-Specific Input Parameters |
|
When sharing
files with other RBCA Tool Kit users, expanded options allow for easy resolution
of discrepancies between project-specific chemical parameters and the active or
default chemical database.
When a RBCA project file is saved, chemical-specific parameters from the active
chemical database are stored along with other project-specific input
parameters. When the file is reloaded the RBCA Tool Kit loads the chemical data
from the saved file, but highlights any parameters that are not consistent with
the default and active chemical databases. The user can easily reconcile any or
all inconsistencies between loaded chemical data and the active database file. |
