DBD Environmental was engaged to undertake remediation of a portion of an industrial site that was historically impacted by solvents, namely Trichloroethene (TCE). The area of the site was required to be assessed and remediated due to the construction of a new warehouse, where the health of construction workers as well as users of the warehouse was required to be protected. In addition, the potential impact to the environment was an important consideration.
A Remediation Options Assessment (ROA) was carried out in conjunction with a Human Health Risk Assessment (HHRA) based on site generated investigation data. This information was then used to inform the warehouse design and the remediation approach.

The main disciplines undertaken included the following:
