Piling and other penetrative ground improvement methods for foundation engineering have the potential in certain circumstances to create adverse impacts on human and environmental receptors when used on land affected by
contamination. I am involved in carrying out a review of these issues for the UK’s Environment Agency National Groundwater and Contaminated Land Centre (NGWCLC), and development of technical guidance on these issues for use by regulators and construction industry practitioners.
The first part of this work has been to undertake a fairly through literature review. The preliminary results suggest that little has been published. Therefore, I would be interested to hear members comments on the subject. As usual I would also be grateful for any information on papers that have been published, or any research that may be underway.
I am also interested in hearing of any cases where the use of piling or ground improvement methods may have been implicated in contaminant or ground/landfill gas migration, or where concern over such migration may have resulted in changes to design or specification of foundations for development. Also of interest are cases where problems have arisen from disposal of contaminated arisings from replacement (bored) piling, or where the aggressive nature of the contamination may have raised material durability issues for the piles.
Clearly there may be issues of confidentiality and any requirements for confidentiality identified will be respected when using information forwarded to me.
Regards
John Anketell-Jones
