Do I Need a Contaminated Land Assessment Before Development?

Before starting any development project, it’s important to understand what’s beneath the surface. A contaminated land assessment helps determine whether soil or groundwater contains harmful substances that could affect your project, the environment, or future occupants.

Sites previously used for industrial activities, service stations, agriculture, or waste disposal may contain contaminants that aren’t visible. Without proper assessment, these issues can lead to construction delays, unexpected remediation costs, and compliance challenges.

A contaminated land assessment typically includes a review of the site’s history, soil and groundwater testing, and recommendations if contamination is found. The results help developers make informed decisions and meet environmental and planning requirements before construction begins.

While not every site requires one, an assessment is highly recommended if the land has a history of potentially contaminating activities or if requested by your local council.

Starting with a thorough site investigation can save significant time and money later in the project.
