Once the existence, type, extent, degree, and nature of contamination are detected and characterized, the next actions to be taken are Environmental Remediation. The correct selection of techniques and technologies to be applied is crucial for project success.
For the design of the Environmental Remediation Project, SGW Services takes into account the type of contamination, hydrogeological and physicochemical conditions of the site, the nature of the existing operation, physical facilities, environmental assets to protect, established remediation goals, and the technical and economic feasibility of the project.
Inovação em Remediação
SGW Services was the pioneer in Brazil to successfully implement ultra-fast In Situ remediation techniques (ISCO, ISCR) using specific remediation products for each type of contaminant that do not form degradation byproducts. The company developed important remediation projects in Brazil and collaborated with international laboratories in studies to adapt products to Brazilian subsoil and climate characteristics.
This ensures our clients have projects prepared for the correct use of remediation products, promoting the remediation of Organic compounds, Organochlorines, Pesticides, Heavy Metals, and Hydrocarbons in a fraction of the time that other techniques take to present results. In some cases, highly complex remediations were verified in less than a year.
SGW Services has extensive experience in applying all currently available environmental remediation techniques. Depending on the characteristics of each case, one or more remediation techniques or a combination of them may be applied:
SGW Services has a specialized team with vast experience in remediation projects for the construction, implementation, operation, and maintenance of systems, ensuring compliance with goals and high-efficiency results.
In all projects, regardless of size and complexity, economic, technical, environmental, legal, and social aspects and the vision of sustainability are considered, without compromising productive capacity and economic growth. These premises, together with the high success rate in achieving established objectives, have made SGW Services a reference in quality for clients, collaborators, and environmental agencies across the country.
Environmental Monitoring
Throughout the entire Environmental Remediation process, regardless of the techniques applied, monitoring of the physicochemical parameters of soil, groundwater, and surface water of the site is necessary.
Environmental Monitoring is carried out by collecting samples of materials such as soil, waste, ambient air, groundwater and surface water, free-phase products, sensitive material or bio-indicator of the site, and remediation products. The results obtained aim to indicate and quantify the presence of contaminants, attest to the efficiency and performance of the implemented remediation system, and the reduction or not of persistent concentrations.
Once remediation goals (CMAs or SSTL) are achieved, a representative monitoring cycle is necessary to ensure the site is remediated and the process can be closed with the environmental agency.
SGW Services is qualified to collect these samples in accordance with current technical standards, ensuring the reliability of physicochemical analysis results performed by specialized and accredited laboratories, as well as analyzing the results and reporting any necessary environmental measures or recommending case closure.
