Remediation Strategies

How we structure thermal remediation projects

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.

01

Assess the subsurface system

We review geology, groundwater behavior, contaminant distribution, and access constraints before recommending a remedy.

02

Select the right thermal strategy

We compare treatment options and define a practical remedy based on mass removal targets, schedule, and cost drivers.

03

Support implementation and optimization

We help guide deployment, monitoring, and operational adjustments to keep performance on track.

About Areha

Building environmental remediation expertise since 2015

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.

2015 Foundation of the company and start of environmental consulting activities.
Growth Expansion into remediation planning, technical evaluations, and project support.
Today Specialized positioning in thermal remediation and complex site recovery strategies.

FAQ

Common questions about thermal remediation consulting

What is thermal remediation?

Thermal remediation uses heat to increase contaminant removal or destruction, often accelerating cleanup in soil and groundwater compared with passive or slower approaches.

When is thermal remediation the right choice?

It is often considered when contaminants are persistent, subsurface conditions are difficult, cleanup time matters, or conventional remedies are unlikely to meet objectives efficiently.
