Contaminated Land Network

Role and Remit

Contaminated land is a global issue and many countries have a legacy of contaminated land resulting from historical industrial activity, waste management and from the previous regeneration of land. Contamination is still occurring across the world, due to inadequate or inappropriate operational controls and regulation in industry and in the management of waste. The presence of contamination can represent an unacceptable risk to human health or the environment.

Our Contaminated Land Network (CLN) supports professionals in the contaminated land sector, providing expert views for the Institution and to be a sounding board for current and new initiatives. The CLN brings together government and non-governmental bodies, industry, academia and other stakeholders to stimulate sharing of knowledge and good practice in the management of contaminated land. The network aims to support the relationship between academic research and practice.

CLN member authored newsletters are published June and December. Read the latest CLN newsletter here.

The CLN has a number of strategic linkages with CIWEM’s Waste and Resources Network as well as through our status as a founding body of SiLC. The SiLC Register brings together professionals from a broad range of backgrounds who advise on land condition matters.


The Specialist Panel produced CIWEM’s Contaminated Land Policy Position Statement which outlines CIWEM’s views and policy position with respect to the assessment, management, remediation and development of contaminated land.

The Specialist Panel also provided input to CIWEM’s Policy Position Statement on Brownfield Development which sets out the position of CIWEM on brownfield development and issues around the legacy of contaminated land and its redevelopment.

Recently there have been changes to the Landfill Tax which impact the construction sector. Specialist Panel Chair Danny Hope has written an article and fact sheet setting out the implications of these changes, summarised in a vlog.


The CLN is a virtual global network, to sign up to the mailing list please email

Specialist Panel

There is a Specialist Panel which meets on a regular basis to discuss topics of interest and concern in the sector and steer the activities of the network as a whole. The Specialist Panel is chaired by Danny Hope, Technical Director at Hydrock.

If you have contaminated land as an element of your post, are interested in contaminated land issues or require further information on joining the Network or Specialist Panel please contact Alastair Chisholm. Membership of the Network is not a major commitment and is a great way to keep in touch with CIWEM’s work on contaminated land issues.
