Neptune models flow and contaminant transport in groundwater, surface water, soil, air, biota, soil vapor, and erosion. We can apply both deterministic and probabilistic models, depending on project needs.

Neptune specializes in quantifying uncertainty for use in state-of-the-art models and custom-built codes, with special expertise in the management and disposal of hazardous and radioactive waste.

Modeling results are presented in easily accessible and collaborative formats for clients and stakeholders.

Our modeling team has a deep base of experience across many applications of fluid flow and contaminant transport simulation and a powerful array of tools for complex modeling problems and environmental decision making.

Extensive expertise with GoldSim (Monte Carlo Simulation Software), hydrologic modeling using FEHM (Finite Element Heat and Mass Transfer Code), and Siberia (landscape evolution software).
