Site Investigations: Lessons From a Late Discovery of Hazardous Waste

The circumstances surrounding the discovery of hazardous chemical on an old industrial site are described. A recently published draft DD175, highlights the increased importance of considering the possibility that certain sites may be contaminated. The paper describes discovery of the waste occurred some time after the site investigation had been completed, and how this situation arose as an unintended consequence of decisions made during the course of the project. Several lessons are drawn regarding the need to explicitly consider contamination, the open-ended nature of site investigation, the trade-off between the cost of an investigation and reduction in risk, and the need for engineers to be aware that, in all projects involving the collaboration of professionals, the efficient exchange of information is essential if problems are to be avoided.
