Brownfield Site Investigation

Verde Project - Pricewaterhouse Coopers


Brownfield site investigation and DQRA for PwC (acting as Administrator)


Co. Dublin, Ireland


Completed 2012

Project Summary/Goals

A former commercial/industrial site was under consideration for redevelopment. A potential purchaser commissioned an environmental report which identified a number of areas of concern across the site in addition to suspected groundwater contamination moving off site.

Further investigations were undertaken by Verde on behalf of the site owner (PwC acting as administer). A Detailed Quantitative Risk Assessment was conducted which concluded the risks associated with the site were not as severe as initially suspected. 

The works were completed to the satisfaction of Local Authority.

Verdé Group’s role on the project

Verde’s role included:

  • Desktop study including all previous site assessment information and all published and unpublished regional environmental information for the site.
  • Intrusive Phase 2 site investigation including borehole installation, trial pitting, soil and water sampling, hydrogeological testing and soil and water level mapping.
  • DQRA was applied to determine the potential risk posed to the wider water environment by this source. Two models were developed to calculate the predicted concentrations of contaminates at the site boundaries.
  • Waste characterization report was completed to identify contaminant hotspots and to determine appropriate and cost effective disposal out lets for soil wastes.
  • A report was prepared which included detailed graphical illustrations of site data which was presented to the client and potential purchaser.
  • Verde liaised with the representatives of the purchaser and also the Local Authority.
