Environmental professionals are encouraged to register at the CLU-IN Vapor Intrusion Mitigation webpage. The training is also available on-demand at the CLU-IN Vapor Intrusion Mitigation archive.
While the documents are designed to assist state regulators, they also serve to raise awareness with environmental consultants and other industry professionals.
