Greenwich University sets up remediation advice line

GREENWICH UNIVERSITY has launched a free telephone helpline for advice on contaminated land remediation.

The helpline is part of a research project into the use of stabilisation/solidification (S/S) techniques in the UK.

The CASSST (Codes and Standards for Stabilisation/ Solidification Technology) project, which began in July 2000, is preparing guidelines for the use of S/S in the treatment of contaminated land and hazardous wastes.

Researchers believe guidelines will improve the uptake of S/S technology in the UK and lead to the remediation of contaminated sites for useful redevelopment as well as providing environmental protection.

Stabilisation/solidification involves the use of cement or other binder such as lime to immobilise contaminants in soils and wastes. While the techniques are used elsewhere in the world, CASST says there is a lack of knowledge and awareness of the methods in the UK.

The project will include a comprehensive review of the science of S/S and the situations where it is likely to be used successfully. A series of decision trees will be produced to show what is involved in its use.

CASSST has been working with a team of S/S and remediation experts and the Environment Agency, which will publish interim guidance from the project at the second annual CASSST conference on 17 April at the university's Chatham Maritime campus.

The conference will also cover the effect of land condition records on contaminated land owners, the risk and risk reduction of contaminated land, insurance and liability associated with it, predicting the performance of S/S wastes in the field and the use of the techniques in the USA and Europe.
