The markers on the following maps indicate where we have been advised of ALWC activity. Most of these sites have been surveyed by us, see NJM free survey offer, but some may be anecdotal through contacts such as you. We would welcome information on incidence known to you. Please contact us via contact us.

If, however, you wish the information to be confidential, please go to Port’s survey questionnaire in our news section. For maps of where NJM has carried out work see our section on project datasheets.
