Contaminated soil

ENVIROSOIL uses the most efficient and reliable technologies to identify, characterise, remove, contain and clear soil and groundwater pollution due to hydrocarbons, heavy metals and other pollutants. We customise our solutions to each problem and client, with a strategy focused on reducing costs and risks. Our goal is to provide maximum efficiency for our clients and to meet the targets we’ve set.

Our assessment and remediation works on soil and groundwater address different business sectors’ needs and fulfil the requirements outlined in Royal Decree 9/2005of the 14th of January, which establishes a list of potentially soil contaminating activities and criteria and standards for declaring contaminated sites.

ENVIROSOIL is an Inspecting Body for potentially polluted soil and associated groundwater, as certified by ENAC (# 299/EI515) according to the UNE-EN ISO/IEC 17020 standard. This guarantees that ENVIROSOIL’s criteria and procedures for planning and implementing inspections of subsoil environmental quality are of the highest standards.

Identification, characterisation, quantification and remediation of environmental liabilities in soil and groundwater

The publication of Royal Decree 9/2005, of the 14th of January, which establishes a list of potentially soil and standards for declaring contaminated sites and its later implementation by local authorities with the specification of Generic Reference Levels for heavy metals, together withLaw 22/2011, of the 28th of July on waste materials and contaminated soil, are the basic regulations governing soil protection, as first outlined in the Rio de Janeiro Summit in 1992.

At the national level, this regulatory framework had a major impact on all potentially polluting industrial activities as well as on land sale operations. It was a real game changer that introduced a polluter pays-principle.

Today, the environmental state of soil is of paramount importance, for its economic as well as its social impact. Environmental liabilities have proved to be a decisive factor in commercial transactions on land and on planning the site’s future use.

ENVIROSOIL has put together a technical and on-site team with years of experience in contaminated soil remediation to advise and assist our clients regarding any environmental issues that might arise from the current regulatory framework. Our main lines of work are:

  • Environmental Impact Assessment (EIA).
  • Environmental control sample analysis.
  • Preliminary soil report
  • Soil state report.
  • Soil Baseline Report (SBR) or initial soil state report.
  • Integrated Pollution Prevention and Control (IPPC).
  • Due diligence environmental audits.
  • Soil and groundwater quality description (sampling and detailed assessments).
  • Quantitative Risk Assessment (QRA).
  • Quantification and valuation of environmental liabilities in soil and groundwater.
  • Computer simulations of subsurface flow and plume spread.
  • Drafting of soil and groundwater remediation projects.
  • Implementation and operation of subsurface improvement projects.
    • In-situ technologies: vapour extraction, air sparging, multi-phase extraction, high vacuum, bioslurping and bioventing.
    • Ex-situ technologies: landfarming, bioheaps, soil washing.
    • Selective digging of contaminated soil and remaining soil certification.
    • Control and monitoring plans after soil remediation. Groundwater analytic tests and tracking of vapour and gas release.
    • Contaminated soil waste management.

ENVIROSOIL’s technical and on-site team have the technical and operative ability to completely develop turn-key projects to first characterise and then remediate Environmental Liabilities in soil.
