List of potentially contaminating activities, industries & landuses

The following list is by no means exhaustive and is provided as a guide only. Consideration may be given to other activities not listed when determining the potential for a site to be contaminated.  Consideration should also be made of surrounding land uses. Where an activity has been undertaken at the site, the site is not necessarily contaminated but there is an increased risk of contamination being present.
