Site CharacterizationInvestigation and Remediation

We provide expert laboratory routine sampling and analysis from site evaluation. Field analysis equipment is also available. Our goal is to help our Customers on data and information that allow them to make a fast and reliable decision on which way to go.

An example of such equipment is the analyzer for Total Hydrocarbon (VOC-C). Having as principle FID detection, this equipment allows us to know the total organic present in a gas sample, from a particular field place or hole or even a monitoring well.

TO-17 is another method that we offer to our Customers. Sampling procedure requires low flow system and high adsorption capacity material (high surface area resin bed) and analysis under GC-MS and thermal desorption systems.

If you work on risk assessment evaluations we are your perfect partners. We can work with you on most of your needs on regular sampling and analysis, including those special or specific chemical compounds. We do have state-of-art equipment and a highly trained Team of professionals at your services.

We already have ISO/IEC 17025 on field sampling fully complied with SMA 90/2012.

Federal regulation Conama 344/2004 establishes principles for sediment characterization and right disposal. This resolution requires physical and chemical characterization for all sediments before to decide the final destination.

Regarding the chemical composition it is required to evaluate the following groups:

  • Total Organic Carbon and Nutrients
  • Polycyclic Aromatic Hydrocarbons
  • Heavy Metals and Arsenic
  • Chlorinated Pesticides

The CONAMA Resolution 420 of 28/12/2009 was issued looking for soil and groundwater characterization, having in mind:

  • Prevention of soil contamination in order to keep functionality and quality protection of surface and groundwater
  • The need to prevent contamination of the subsoil and groundwater that are public property and strategic reserves for public supply, and environmentally sustainable development
  • To establish criteria for defining guidelines for the prevention of soil contamination, risk assessment evaluation
In light of these needs, this resolution establishes criteria for soil and groundwater characterization. Groundwater maximum concentrations allowed was issued for:
  • Inorganic Compounds
  • Chlorinated Benzene
  • Phthalic Esters
  • Chlorinated Ethenes
  • Chlorinated Ethanes
  • Chlorinated Phenols
  • Non-Chlorinated Phenols
  • Volatile Aromatic Hydrocarbons
  • Polycyclic Aromatic Hydrocarbons
  • Chlorinated Methane
  • Polychlorinated Biphenyls (PCBs)
  • Chlorinated Pesticides

Regarding the soil, should be evaluated the following characteristics:

  • Physical Characteristics
  • Inorganic Compounds
  • Phthalic Esters
  • Chlorinated Pesticides
The CETESB, Environmental State Agency in São Paulo, establishes the criteria for soil and groundwater characterization thought "Decisão de Diretoria No 195" in 23/Nov/2005. The parameters and chemical groups are the same established by CONAMA 420/09.
