JGP can provide high quality, targeted investigations and cost effective remediation solutions for the development of contaminated sites. Many previously developed sites (sometimes referred to as ‘Brownfield’ land) can be successfully and safely redeveloped. JGP has worked with numerous clients, both in the private and public sectors, in the investigation and remediation of polluted soils and groundwater. We can provide contamination assessments tailored to your specific needs and can guide developers through planning and legislation, including Part IIA of the Environmental Protection Act 1990 and current planning policy guidance.


Contaminated Land Assessments & Remediation

The risk of contamination is usually addressed in a phased approached as follows:

  • Phase I Desk Study: to identify any potential sources of contamination
  • Phase II Site Investigation: conducted when a contamination risk is perceived
  • Phase III Remediation Strategy: produced where an unacceptable risk is found
  • Phase IV Verification Report: to validate that risks have been removed

Where elevated levels of contaminants are present above National guideline values, a site-specific Quantitative Risk Assessment (QRA) can be conducted, which can remove or substantially reduce the need for expensive remedial strategies.  JGP has considerable experience in conducting QRAs and risk assessing contamination, including:


  • The bioaccessibility, speciation, plant uptake and overall toxicity of various metals, including arsenic

  • The identification, characterization and toxicological assessment of hydrocarbon and organic contamination and the design and supervision of bioremediation and natural attenuation schemes

  • The on-site delineation of contamination hotspots and site-specific clean-up levels, minimising the amount of material needing to be remediated or removed to land-fill, providing considerable cost savings
