Title: MINTEQA2 |
Model Type: Software |
Scope of Model: MINTEQA2 is a
geochemical equilibrium speciation model for dilute aqueous systems. The
model is an update of MINTEQ, which was developed by combining the
fundamental mathematical structure of MINEQL with the well-developed
thermodynamic database of WATEQ3. Because of MINTEQA2's public domain
status, extensive feedback has been received from users on needed
corrections and enhancements.
This model was last updated and released by EPA's Center for Exposure
Assessment Modeling (CEAM) in 1991, and is in need of updating. |
Available from: Model can be downloaded free
of charge from http://www.epa.gov/ceampubl/minteq.htm |
Title: PELMO |
Model Type: Software
Scope of Model: PELMO (Pesticide Leaching Model) was developed to
estimate the leaching potential of pesticides through distinct soil
horizons based on an extended cascade model. Processes include estimating
of soil temperatures, pesticide degradation, sorption, volatilization, and
estimating of potential evapotranspiration by using Haude equation. The
model is an enhancement of the 1984 version of PRZM. Applications to date
have mostly involved pesticide leaching scenarios on German soils.
PELMO is based on PRZM-Model, but more processes are included because
of significant limitations in PRZM. Similar to PRZM, PELMO has two major
components: hydrology and chemical transport. While the hydrology
component for calculating runoff and erosion is based on the USDA Soil
Conservation Curve Number technique and the Modified Universal Soil Loss
Equation (same as PRZM), the calculation of evapotranspiration is
estimated by using the Haude equation or by direct input of the potential
evapotranspiration. PELMO calculates depth dependent temperature in soil
by using daily air temperatures. |

Title: PRZM-2 (Pesticide Root Zone Model) |
Model Type: Software |
Scope of Model: The Pesticide Root Zone Model
(PRZM-3) is a one-dimensional, dynamic, compartmental model that can be
used to simulate chemical movement in unsaturated soil systems within and
immediately below the plant root zone. It has two major components -
hydrology (and hydraulics) and chemical transport. |
The model was specifically designed to provide loadings to selected
media, including air, water, groundwater and plants. PRZM 3 is a
daily-time-step agricultural field simulation model. Outputs include
pesticide leaching depth, runoff volume, eroded sediment mass, pesticide
movement with eroded sediment and runoff, and pesticide volatilization.
Processes modeled include, water movement through the soil profile, crop
uptake, vapor phase transport, and irrigation. Two pesticide degradates
can be modelled along with the parent. PRZM 3 has incorporated the VADOFT
program which estimates chemical movement through the vadose zone below
the surface soil. A Monte Carlo shell is also included. The model is
currently being used to estimate the pesticide runoff to surface waters
through various routes. |

Title: PREScore |
Model Type: Software |
Scope of Model: EPA's Superfund Program
developed the PREscore software to assist with site investigations and
Hazard Ranking System (HRS) scoring. The Hazard Ranking System (HRS) is
the scoring system used by EPA's Superfund program to assess the relative
threat associated with actual or potential releases of hazardous
substances.
The HRS may be useful in site characterisation/ranking, in that it uses
a structured analysis approach to scoring sites. This approach assigns
numerical values to factors that relate to risk based on conditions at the
site. The factors are grouped into three categories:
- likelihood that a site has released or has the potential to release
hazardous substances into the environment;
- characteristics of the waste (e.g. toxicity and waste quantity); and
- people or sensitive environments (targets) affected by the release.
Four pathways can be scored under the HRS:
- ground water migration (drinking water);
- surface water migration (drinking water, human food chain, sensitive
environments);
- soil exposure (resident population, nearby population, sensitive
environments); and
- air migration (population, sensitive environments).
After scores are calculated for one or more pathways, they are combined
using a root-mean-square equation to determine the overall site score. |

Title: SADA � Spatial Analysis and Decision
Assistance |
Author: University of Tennessee Research Corp |
Model Type: Software |
Scope of Model: Spatial Analysis and Decision
Assistance (SADA) is a Windows 95 environmental software package. It
incorporates tools from various fields including visualisation, geospatial
analyses, statistical analysis, human health risk assessment, cost/benefit
analysis, sampling design, and decision analysis into an interactive
environment. Each of these modules can be used independently or in an
integrated fashion to address site-specific concerns in the
characterization and remedial action design.
SADA was designed to simplify and streamline several of the processes
in environmental characterisation and to bring the information together to
help site investigators make decisions about site management options. SADA
however, is particularly useful to display and manipulate site data within
a spatial framework.
The developers of SADA propose to integrate ecological and human risk
assessment within one software platform. It is proposed that SADA will be
supported by an accompanying database of ecotoxicological information
concerning species, life history parameters, chemical toxicity, and
bio-accumulation.
The developers proposed to provide site investigators with more current
and more advanced methods for assessing risk than those commonly applied.
A multi-modelling approach will be developed to provide some traditional
modelling tools (such as aggregated and matrix models). However, the
developers main objective is the introduction of individual - based,
physiologically structured population and community models (IBMs) into
assessment technology.
IBMs are being developed to provide a bridge between exposure and
effects on individual organism models and its extrapolation to population
and community level effects. |

Title: HSSM - The Hydrocarbon Spill Screening
Model |
Model Type: Software |
Scope of Model: The Hydrocarbon Spill
Screening Model (HSSM) simulates the subsurface flow of a
lighter-than-water, nonaqueous phase liquid (LNAPL) and its associated
aquifer contamination. The most common example is a petroleum fuel such as
gasoline or diesel that has been released from a leaking underground
storage tank. When the fuel reaches the water table, it may form a lens or
smear zone. Through the fuel's contact with the aquifer, ground water
contamination can result.
Chemical components of the fuel (benzene, toluene, ethylbenzene,
xylenes, methyl tert-butyl ether) dissolve into the ground water according
to their solubilities and the hydrology of the system. The contaminants
then can be transported in the aquifer to receptor wells. One of the most
important reasons for inclusion of the LNAPL or fuel phase in simulating
aquifer contamination is that the chemical contaminants are released
slowly from the fuel phase. Accurate estimation of the loading to the
aquifer requires the simulation of contaminant dissolution from the fuel.
HSSM simulates contamination associated with these fuels by using three
simplified modules that represent the vadose zone, the fuel lens within
the capillary fringe, and the aquifer. Each module was developed from a
semi-analytical solution of the governing equations. The simplified
solutions reduce the extensive computational burden of a fully numeric
approach. Lack of availability of field data often limits usage of complex
models, and HSSM attempts to include the important phenomena at a
reasonable data and computational cost.
The three modules of HSSM are linked in a windows interface that allows
for interactive input of data, running of the models, and automated
graphing of the model output. A two volume user's guide provides specific
instruction for running the model, guidance on selecting input parameter
values and interpreting the model output, in addition to the theoretical
background of the model. Example applications to field data problems are
available from Internet links given on the HSSM distribution page. |

Title: EXAMS 2.98.01 (Exposure Analysis Modeling
System) |
Model Type: Exposure simulation software |
Scope of Model: Exposure simulation model
looking at effect of a chemical on a ecosystem, concentrations, fate and
transport. EXAMS simulates an aquatic ecosystem, tracing the path and
behaviour of a toxic pollutant. It has a database of toxic substances and
a command-driven interface, which allows for the definition of new
substances and for modification of the ecosystem definition. Each water
body may be modeled by using up to 32 different segments, for each of
which up to 28 different substances may be simulated. The basic phenomena
taken into consideration are accumulation, chemical and biological
transformation, and transport. Environmental conditions may be constant
(in the short or the long term) or varying monthly. It may be use to
conduct rapid evaluations and error analyses of the probable aquatic fate
of synthetic organic chemicals.
EXAMS combines chemical loadings, transport, and transformation into a
set of differential equations using the law of conservation of mass as an
accounting principle. It accounts for all the chemical mass entering and
leaving a system as the algebraic sum of external loadings, transport
processes that export the compound from the system, and transformation
processes within the system that convert the chemical to daughter
products. The program produces output tables and simple graphics
describing chemical exposure, fate, and persistence.
EXAMS (v2.98.01) combines properties of synthetic organic chemicals
and aquatic ecosystems to characterize the ecotoxicology, persistence, and
mobility of pesticides and industrial materials in surface water. This
model has been used for over 12 years and the feedback has been positive. |

Title: EMSOFT: Exposure Model for
Soil-Organic Fate and Transport |
Model Type: Software: Exposure Model for
Soil-Organic Fate and Transport |
Scope of Model: A screening model that
primarily ranks the relative volatilization potential of different organic
chemicals. The EMSOFT Model is largely based on the work and theories
developed by William A. Jury. It characterises volatilisation of organic
chemicals from contaminated soils to the atmosphere, a significant human
exposure pathway (USEPA, 1997).
Volatilization of organic chemicals from contaminated soils to the
atmosphere and subsequent inhalation represents a potentially significant
human exposure pathway. The manual (USEPA, 1997), describes a screening
model that may be used to assess the potential for such exposure to occur
and quantify the mass flux of contaminants to the atmosphere over time.
Mass fluxes can then be input to an atmospheric dispersion model to
calculate exposure concentrations.
Ingestion of contaminated soil and dermal contact are also potentially
important exposure pathways. The EMSOFT model can also be used to
calculate chemical concentrations in surficial soil layers over time for
assessment of these exposures. The model addresses situations in which
contaminated soils are located at the surface and buried beneath a clean
soil cover. |
Assessment: Likely to be more useful in human
health risk assessment. |

Title: RiskEZ |
Author: Pinyon Software |
Model Type: Risk Assessment DSS Software
program for Windows. |
Scope of Model: Designed to simplify and
speed up the risk assessment process, and ensure more accurate risk
assessment results. RiskEZ ships with all the information needed to
complete a risk assessment. RiskEZ contains standard EPA exposure
equations, default parameter values, and toxicity information from EPA�s
IRIS and HEAST databases. RiskEZ can import toxicity data from IRIS
updates. RiskEZ�s resources include:
- Chemical table containing over 3,500 chemicals and 15,000 synonyms.
- Toxicity values for hundreds of chemicals taken from EPA�s IRIS
and HEAST databases as well as from Cal\EPA.
- Default EPA exposure equations defined for nine populations.
- EPA risk equations and RBC (risk-based concentrations) equations.
- Default EPA values and equations for over 70 parameters.
- Twenty-seven predefined exposure pathways.
Exposure concentrations may be stored in almost any format, including
Excel, Lotus 123, Quattro Pro, Paradox, dBase, and ASCII text files and
updated as new site information becomes available during the risk
assessment process.
Pinyon Software believe that RiskEZ is environmental software that
dramatically improves the speed and quality of assessing and remediating
contaminated sites. |

Title: LEADSPREAD 7.0 |
Author: California Department of Toxic
Substances Control, Human and Ecological Risk Division (?). |
Model Type: Excel spreadsheet
model to estimate blood lead concentrations. |
Scope of Model: LeadSpread is a tool
that can be used to estimate blood lead concentrations resulting from
exposure to lead via dietary intake, drinking water, soil and dust
ingestion, inhalation, and dermal contact. Each of these pathways is
represented by an equation relating incremental blood lead increase to a
concentration in an environmental medium, using contact rates and
empirically determined ratios. The contributions via the five pathways are
added to arrive at an estimate of median blood lead concentration
resulting from the multi-pathway exposure. Ninetieth , ninety-fifth,
ninety-eighth, and ninety-ninth percentile concentrations are estimated
from the median by assuming a log-normal distribution with a geometric
standard deviation (GSD) of 1.6. |

Title: EcoFATE |
Model Type: Environmental risk assessment
software package for Microsoft Windows |
Scope of Model: Ecosystem based environmental
and ecological risk assessments of chemicals emissions by point and
non-point sources in freshwater and marine aquatic ecosystems, including
lakes, rivers and marine inlets.
Used to assess the cumulative impact of chemical inputs in terms of
contaminant concentrations in water, sediment and biota of an entire
ecosystem and to interpret these concentrations in terms of exceedance of
environmental criteria and standards, potential for toxic effects in biota
of the ecosystem and risks to human beings exposed to contaminated fish
products or contaminated water
Consists of a combination of an environmental fate, food-web
bioaccumulation, toxicological hazard, and human health risk assessment
model, which are integrated to directly relate chemical emissions to
concentrations, toxic effects and human health risks. Each of the models
is based on best available knowledge of the mechanisms of chemical
distribution, toxicity and risk. The assessments can be done on a
time-dependent and time-independent (i.e. steady-state) basis
DSS used to investigate whether existing or planned chemical emissions
can be expected to pose an ecological or human health risk, meet
environmental quality standards or criteria and to identify the
"assimilative capacity" of ecosystems for chemical substances in
terms of maximum daily loadings |
Assessment: Useful, comprehensive model. Not
validated. Review |
