On previous and actual times, there is a high concern about the interaction of mining, industry and municipality waste with the groundwater flow regime, groundwater quality and potential impacts to downstream water bodies and water sources. Contaminant transport modeling is key to understand the development of the contaminant plumes, to quantify the impacts to water quality and mostly important to design groundwater remediation schemas.

Hatarilabs has a wide expertise on contaminant transport modeling with experience on several cases covering unsaturated transport, multiphase transport, reactive transport, transient calibration with observed concentrations, mass balances. Hatarilabs handle tools and scripts to incorporate big amount of observation data on extensive periods of time with high quality control on model construction and high accuracy on the model predictions.

Groundwater management in karstic aquifers has several challenges because of the characterization of a mixed flow in porous media and karstic conduits and the high uncertainty in the geometry and flow properties of the conduit network. Numerical modeling is a tool to provide effective answers for the evaluation of flow and quality in a karstic network, the interaction with water bodies and the availability/vulnerability as a water source. 

Due to intense aquifer exploitation in certain coastal areas, done to satisfy the requirements from agriculture, industry, cities and touristic development, the salinization process is intensified and produces a saline front from the sea or deep saline aquifer horizons.

Hatari Labs develops variable density numerical models related to aquifer salinization that consider the main physical process related to saline intrusion. These numerical models have the objective to assess the current and future situation from the groundwater flow regime in terms of flow and water quality.
