Contaminated Land Training Modules

There are currently five contaminated land training modules (CTL1 to CTL5), each of which contain a series of related units (defined under separate headings; CTL1.1, CTL1.2, etc.). When constructing a training programme, we can either deliver one or more modules in their entirety or we can mix and match individual units to tailor the training to your particular needs.
