The EIA Remediation of Land and Groundwater working group is one of EIAs leading policy and regulatory groups. It represents a very broad spectrum of contamination specialists and technical experts from toxicologists, to remediation consultants and contractors, from legal professionals to tax specialists. Our meetings always attempt to invite a guest speaker on an issue which is impacting on the wider sector. Our meetings cover both strategic policy issues as well as technical scientific regulatory issues. All members are able to raise issues onto the agenda with actions collectively agreed by the Members.
The Group meets 4 times a year in person to allow networking. Members are permitted to invite guests via agreement of the secretariat. The working group primarily focuses on the remediation of contaminated land sites or complex brownfield sites seeking remediation before development. Our Members work closely with DEFRA, Environment Agency and developers who are seeking to clean up sites which have complex environmental constraints. We also get regular updates from other related organisations such as the National Brownfield Forum.
Current issues being discussed:
- National Planning Policy Framework and implications on Brownfield vs Grey belt development
- Definition of Brownfield development
- Permit delays and inconsistency in decision making by Environment Agency
- Asbestos in soil
- Coal Tar remediation
- Oil spills remediation and hydrocarbons
- Radon Gas awareness and mitigation
- Category 4 screening levels
- Wider soil policy
