Potentially contaminating activities (PCA)


We quantify, evaluate and simplify the risk analysis process, helping professionals and consumers to make better and more informed decisions during the property transaction lifecycle.

By considering the current activities, industries, and land uses in an environmental land assessment, professionals can effectively identify potential contamination sources and take appropriate measures to safeguard the environment and public health. Such assessments are vital for ensuring responsible land management practices and for making informed decisions regarding land use and development.

Certain activities are designated as notifiable activities, which means they require regulation to operate legally.


These activities encompass a wide range of operations, including large-scale industries such as chemical manufacturing, oil and gas processing, waste disposal, power stations, timber and paper mills, among others.

To streamline the assessment process, Land Insight has compiled a comprehensive list known as potentially contaminating activities (PCA). This compilation encompasses a diverse range of activities, businesses, industries, and land uses that have the potential to cause land contamination.


Examples of PCAs include service stations, cattle dips, tanneries, wood treatment sites, landfills, fuel storage facilities, and more. For each of the PCAs mapped by Land Insight, a detailed explanation is provided to enhance understanding and facilitate the assessment process. This comprehensive mapping allows for a systematic evaluation of the potential sources of contamination and assists in determining the extent and nature of the environmental risks associated with the land in question.
