NCLOG

​

The National Contaminated Land Officers Group (NCLOG) is a member-led, specialist interest group and is part of the Institution of Environmental Sciences. NCLOG members are Contaminated Land Officers (CLOs) working in local authorities.
 
The community works together to act as the national voice for CLOs in the UK and to promote high-quality and consistent regulation and management of land contamination across the sector. We provide a home for CLOs to share ideas and knowledge, support members through developing guidance and resources and provide peer support to individual CLOs, who may be the sole individuals dealing with land contamination in their Council.  
 
NCLOG has over 200 members across the UK and has strong links with regional Contaminated Land Officer Groups through its Regions Forum.

​
