Potentially Contaminating Industries

The initial phase of an environmental land assessment is crucial and involves thorough consideration of the various activities, industries, and land uses that have taken place or may have occurred historically on the land or in its vicinity. This assessment aims to determine whether these activities could have led to the introduction of pollutants into the land or groundwater, resulting in contamination.

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. However, it is important to note that even smaller businesses like dry cleaners, mechanics, spray painters, and other similar establishments that handle or work with hazardous substances can also fall under this category.

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.

By considering the historical and current activities, industries, and land uses in an environmental land assessment, and by referring to resources such as the PCA list compiled by Land Insight, 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.
