Use of QGIS for equipment and utility layout, field positioning, and implementation constraints in sites with operating restrictions.
Simulation of heating processes associated with thermal remediation, including heat dispersion and the response of model layers such as the vadose zone, saturated zone, and aquitards.
Sectors Served
This area is ready for you to later refine with the real segments, geographies, and client profiles served by Areha.
Sites with complex operational history, legacy liabilities, and the need for robust technical planning.
Facilities requiring environmental management, risk support, and remediation strategies compatible with active operations.
Scenarios involving persistent contaminants and careful technical review of possible treatment alternatives.
Projects that need remediation aligned with occupancy, reuse, or property transaction schedules.
Trust Signals
Technical support structured to guide environmental remediation projects with consistent decision-making, compliance awareness, and safe implementation.
Remediation Strategies
The goal is not just to apply heat. It is to match the right treatment intensity, schedule, and controls to the site conditions and remediation objectives.
We review geology, groundwater behavior, contaminant distribution, and access constraints before recommending a remedy.
We compare treatment options and define a practical remedy based on mass removal targets, schedule, and cost drivers.
We help guide deployment, monitoring, and operational adjustments to keep performance on track.
Projects
A selection of real projects reflecting Areha’s work in environmental remediation, system implementation, and operational support across different technical scenarios.
Pharmaceutical Industry | Sao Paulo, Brazil | 2025
Problem: chlorinated solvent contamination in an industrial area requiring a high-efficiency technical response and stronger performance predictability.
Solution: design, assembly, and implementation of a thermal remediation system integrated with SVE, structured to match site conditions and recovery objectives.
Result: removal of 95% of the estimated mass in 3 months of operation, supporting consistent progress in the site remediation strategy.
Former Industrial Laundry | Saxony, Germany | 2025
Problem: chlorinated solvent contamination in an area requiring intensive treatment and close control over implementation and operation stages.
Solution: remediation design, equipment supply, assembly, implementation of the thermal system, and testing and start-up of a thermal remediation system associated with MPE/SVE.
Result: removal of more than 3 times the mass estimated during investigation after 6 months of operation, reinforcing the effectiveness of the implemented strategy.
Airline Company | Campinas, Brazil | 2023 to present
Problem: preventive and corrective service needs in the client’s wastewater treatment plant, which had operational availability below 50% before service mobilization.
Solution: provision of specialized labor, maintenance reporting, equipment diagnostics, vendor sourcing, and support for specifying replacement assets reaching end of service life.
Result: wastewater treatment plant availability above 80% after service start, with a consistent improvement in system operational reliability.
Auto Parts Industry | Sao Paulo, Brazil | 2018 to present
Problem: chlorinated solvent and TPAH contamination in an area requiring stable remediation system performance and consistent operational improvement.
Solution: provision of labor for operation and maintenance of all remediation equipment installed at the site, together with implementation of operational improvement measures.
Result: average system operating availability increased from less than 60% to more than 95% of the time after the improvements proposed by Areha were adopted.

About Areha
Founded in 2015, Areha Environmental was established to support clients facing complex environmental liabilities through technically sound solutions and qualified guidance for environmental remediation decision-making.
The name Areha comes from "o'reho", a term from the language of the Xavante, one of Brazil's Indigenous peoples, associated with the meaning of deep water or groundwater. That reference expresses, in both a symbolic and technical sense, the essence of the company and its connection to one of the most strategic and sensitive resources below the surface.
Based on that meaning, Areha Environmental's work is guided by the protection of the subsurface and the preservation of its most valuable resource, groundwater, through solutions focused on investigation, remediation, and responsible environmental recovery.
Over the course of its trajectory, the company strengthened its role in environmental remediation consulting, supporting the understanding of site conditions, the careful evaluation of treatment alternatives, and the development of projects from investigation through implementation, with particular attention to scenarios where thermal remediation offers a more efficient and strategic response.
FAQ
Thermal remediation uses heat to increase contaminant removal or destruction, often accelerating cleanup in soil and groundwater compared with passive or slower approaches.
It is often considered when contaminants are persistent, subsurface conditions are difficult, cleanup time matters, or conventional remedies are unlikely to meet objectives efficiently.
