BP RISC Model Description

 

BP RISC 4 is a software package for performing fate and transport modeling and human health risk assessments for contaminated sites. A unique feature of BP RISC 4 is its ability to perform a backward risk calculation as well as the conventional forward risk calculation. The backward risk calculation in BP RISC 4 refers to calculating a cleanup level for an input value of risk. Fate and transport models are available in BP RISC 4 to estimate receptor point concentrations in groundwater and indoor and outdoor air. No other RISK package offers all this! BP RISC 4 can be used to estimate the potential for adverse human health impacts (both carcinogenic and non-carcinogenic) from up to nine exposure pathways. Additional pathways and other non-human health impacts may be considered in future revisions of RISC.

Key New Features in BP RISC Version 4

 

Version 4.0 of BP RISC has new features that give it even greater flexibility in assessing risk for the following scenarios:

  • Irrigation pathways, i.e. water used for gardening but not for indoor usage
  • Vegetables grown in contaminated soil
  • Two new vapor models , where the vapors are allowed to biodegrade during transport through the unsaturated zone
  • Models for surface water and sediment contamination from impacted groundwater and direct comparison with relevant national standards for these media
  • The use of groundwater MCLs (maximum concentration levels) and surface water concentrations in addition to acceptable risk levels as the criteria for back-calculating clean-up targets
  • The ability to calculate a site-specific target level (SSTL) for a TPH mixture using the site-specific measured concentrations of the TPH fractions detected in the soil

We feel confident that BP RISC Version 4.0 provides the latest and most complete package for calculating risk to human health and surface water. This version has been peer-reviewed by Arcadis, Geraghty and Miller in Cambridge, UK. Their review is included in Appendix R

BP RISC 4 Features

 

BP RISC 4 Main Features Include:
  • A customizable chemical database with 82 chemicals
  • An Excel spreadsheet based on the RBCA algorithms that can be used to replicate the tiered RBCA process
  • A detailed user's manual with three in-depth example problems
  • The ability to determine risk-based TPH (total petroleum hydrocarbon) targets using the TPH fractions proposed by the U.S. Air Force led TPH Working Group
  • The ability to calculate additive risk due to multiple pathways, compounds and receptors (such as a resident exposed as both a child and an adult)
  • A Monte Carlo capability for probabilistic risk evaluation
  • Fate and transport models that distinguish between presence and absence of phase-separated product (NAPL) in the source zone
BP RISC 4 Exposure Pathways Include:
  • Ingestion of soil
  • Dermal contact with soil
  • Ingestion of groundwater
  • Dermal contact with groundwater
  • Inhalation in the shower
  • Inhalation of outdoor air
  • Inhalation of indoor air
  • Ingestion of surface water
  • Dermal contact with surface water
BP RISC 4 Fate and Transport Models Include:
  • Johnson and Ettinger indoor air model

 What's Coming in BP RISC 5 Model

 

New Features for BP RISC5:

 

         Food web screening models for terrestrial and aquatic ecological risk assessments

         Output tables and charts are now created directly in Excel

         Particulate emission model added

         New plant uptake model (Trapp and Matthies, 1995)

         BP RISC 5 model chemical database has been expanded to ~120 chemicals (from 80)

         User can choose to use either reference concentrations and unit risk factors, or,  inhalation reference doses and inhalation slope factors

         All chemical toxicity values updated to be current with USEPA values

         Chemical database is much easier to edit and generate summary tables of chemical properties

         Mass balanced, depleting source, added to indoor and outdoor air models

         References provided (on-line and in Excel tables) for all chemical and receptor parameters

         New databases: 

o       Ecological receptors and receptor-specific information

o       Mammalian and avian toxicity values

o       Worm and plant toxicity values

o       Soil and plant screening values

         New human receptor profiles added (including ones for additive receptor cases)

         User can add new receptor and soil profiles and/or may customize default values

         Sediment was added as a media of concern for human health risk (dermal contact and ingestion exposure pathways)
