Our SaaS software is organized into two business areas: Contaminated Land (SSP) and Hydrogeology. Independent calculation engines, compliant with French regulatory frameworks, EFSA 2020 and EPA. No installation — everything runs in the browser.
Geographic scope of the data used
Risk assessment (EQRS, ECOTOX, Johnson & Ettinger): these software tools rely on internationally recognized reference toxicological and physicochemical values (US EPA, ANSES, EFSA, INERIS, ECHA). They can be used for studies carried out in any country.
Hydrogeology (Groundwater Drawdown, Soil → Groundwater → Well Transfer, GEP/DLE Modeling, ANC Sizing): these software tools automatically retrieve geological and piezometric data from French national databases (BRGM, Hub'Eau). This automation is currently operational for France. For a study carried out in another country, the required hydrogeological parameters must be entered manually by the user, pending the progressive automation of databases by country.
Human health and ecotoxicological risk assessment, pollutant transfer, conceptual site model, 3D modeling and soil pollution source diagnosis.
