We provide state-of-the-art solutions for the management of impacted sites.

Management of Impacted Sites

We understand that the correct consideration of technical, administrative and legal variables is crucial for the responsible management of contaminated sites, enabling us to provide our clients with a perspective that goes beyond compliance. We therefore strive to develop solutions that are sustainable in the long run, while addressing the risks associated to each situation in a clear and transparent manner.

High-Resolution Environmental Investigation

We firmly believe in establishing a conceptual model as the base for any investigation, whether ESA Phase 1, Phase 2 or Phase 3, clarifying to our clients the rationale for each data acquisition process.

  • High resolution investigations using MIP-HPT;
  • Investigative soil boring and sampling using direct push technique;
  • Installation of 2”, 4” and 6” wells using Hollow Stem Auger (HSA);
  • Three dedicated vehicles for low-flow sampling;
  • Development and consolidation of local conceptual models;
  • Hydrogeological assessment and testing, human health risk assessment, and mathematical modeling.

Precision Environmental Remediation

We focus on innovative solutions for the design and application of state-of-the-art remediation techniques that are tailored to the needs of our clients.

We are experts in the application of oxidizers via direct push, and in the development of remediation solutions that are integrated to other techniques (MPE, Pump & Treat, SVE and Air Sparging), whenever necessary.

All of our remediation systems have an integrated data logger system that enables our operators and clients to view, at any given time, their complete history of system operation.

Remediation of organic compounds with combined tools and techniques

  • ISCO: over 50 projects carried out in the last 4 years;
  • Incorporation of MIP-HPT to remediation supporto;
  • Direct Push:know-how from the pressurized application of 300 metric tons of chemical oxidizers;
  • Oxidizing agents used: sodium persulfate and percarbonate, calcium peroxide, potassium permanganate, etc;
  • Formulations: testing and application of additives to control reaction stability [persistência da reação] and enhance the availability of the oxidizing agent in the medium;
  • MPE: more than 40 operational systems;
  • Other techniques: surfactants, P&T, SVE/AS, etc.

Application of MIP + ISCO Technology – Assumptions and Conditions

  • Previous understanding of the nature of the contamination, chemicals of concern and remediation goals;
  • Feasibility study: preliminary definition of schedules and metrics, and determination of the oxidizer demand in the soil;
  • High resolution investigation (MIP-HPT) to refine the Conceptual Model (Remedial Investigation);
  • Basic sequencing of the ISCO technique: formulation of oxidizers, injection points and depths (direct push), pressures and volumess;
  • Eventual use of associated techniques: MPE, surfactants, etc;
  • System with own, online, remote monitoring (“SIGA” remote supervision) [Sistema com telemonitoramento online e próprio (supervisório remoto SIGA)];

High-resolution investigation and in situ remediation.

Remediation through Combined Techniques

Porto Alegre/RS, 2011-2014

The subject area was a former industrial site impacted with VOC and oil LNAPL, where the client intended to build a residential gated community.

Finkler Ambiental submitted a remediation proposal for the adoption of various techniques, which could be applied either separated or combined. We carried out interventions with oxidant (ISCO) and surfactant injection, multiphase extraction (MPE), hot spot removal and biopiling for the treatment of the contaminated soil.

At the end of 2014, the area was considered recovered by the local environmental department (SMAM), which enabled its new occupation.

Management of Industrial Site Impacted with VOC

Mauá/SP, 2010-2014

Due to contamination detected at the employee recreation area, the site’s request to renew its groundwater intake permit was denied, which jeopardized the operation of the plant.

Finkler Ambiental conducted additional investigations and pollutant dispersion mathematical modeling studies, and concluded that remediation actions were not required in the site.

The state environmental agency (CETESB) considered the site as being rehabilitated, which enabled the renewal of the permit at the water department (DAEE).

Rehabilitation of Impacted Site for Real Estate Development

Porto Alegre/RS, 2013-2015

The site had residual VOC contamination in the soil, and had already been the object of groundwater remediation. At the time, the client had decided to carry out extensive soil removal, and the associated costs would render certain project alternatives financially unfeasible.

Finkler Ambiental submitted an alternative remediation proposal using in situ chemical oxidation (ISCO), developed based on additional investigations to refine the conceptual model.

The remediation goals have already been reached and the site is being monitored, so it can be designated as a recovered site by the local environmental department (SMAM).
