Forecast movement
Predict where chemicals may travel through water, air and along shorelines.
Chemical discharge modeling and response
CHEMMAP
CHEMMAP predicts the transport, fate and potential biological impacts of chemical releases in marine, freshwater and atmospheric environments, helping teams visualize outcomes, assess risk and support response decisions.
Built for complex release scenarios
An integrated platform for chemical spill response, planning and assessment.
Chemical spills behave differently depending on the substance, environmental conditions and release scenario.
CHEMMAP brings these variables together in one modeling system so users can forecast transport, evaluate concentrations, explore uncertainty and understand potential environmental impacts.
Evaluate impacts
Assess changing concentrations, exposure pathways and potential environmental receptors.
Plan with confidence
Test worst-case scenarios, train response teams and support contingency planning.
Complex science made visual
Chemical transport and fate results presented through clear, map-based workflows.
Use the placeholders in this section for CHEMMAP screenshots showing surface concentrations, dissolved plumes, atmospheric dispersion, sediment accumulation and 3D model results.

Advanced modeling capabilities
Follow the full lifecycle of a chemical release.
01
Trajectory and fate modeling
Predict where chemicals will move and how they will transform.
CHEMMAP simulates spreading, transport, dissolution, volatilization, degradation, sediment interaction, resuspension and shoreline contamination across time.
02
Stochastic modeling services
Explore uncertainty, probability and environmental thresholds.
Service-based stochastic studies evaluate the range of possible contamination outcomes, probability of threshold exceedance and statistical distributions of model results.
A connected modeling workflow
Define the substance. Apply the environment. Evaluate the outcome.
Define the chemical
Select substance properties, release amount, duration, phase and discharge depth.
Set the scenario
Configure location, timing, release conditions and environmental assumptions.
Apply environmental data
Use winds, currents, temperature, salinity, bathymetry and related datasets.
Review transport and impacts
Examine concentration fields, fate processes, sediment interaction and potential exposure.
CHEMMAPTurn complex chemical behavior into an understandable response picture.
CHEMMAP processes
Model the physical and chemical pathways that shape each release.
Surface movement and spreading
Simulate the movement and spreading of floating chemicals and materials.
Air and water transport
Model evaporation, volatilization and dispersion through the atmosphere and water column.
Dissolution and degradation
Track changing concentrations as substances dissolve, transform and naturally degrade.
Sediment and shoreline interaction
Evaluate accumulation, resuspension, shoreline contact and contamination pathways.
Key applications
Support response, planning, assessment and post-incident analysis.
Spill response and emergency management
Forecast movement and concentrations to support response strategies and operational decisions.
Contingency planning
Model worst-case discharge scenarios and identify locations or resources that may be affected.
Environmental assessment and hindcasting
Evaluate point-source discharges, exposure risks and past events to understand environmental outcomes.
Built on robust data and science
Connect chemical properties with the environmental conditions that drive each scenario.
CHEMMAP combines global environmental datasets, scientific process models and an extensive chemical database.
Users can work with currents, winds, temperature, salinity, bathymetry and other real-time or historical datasets, alongside substances such as acids, bases, petroleum hydrocarbons, ammonia and floating materials.
