Frequently Asked Questions

What is a soil contamination risk assessment?

A soil contamination risk assessment evaluates the potential for harmful substances to be present in your soil. Our estimator provides a preliminary, educational assessment based on factors you select, such as past land use, proximity to potential sources of pollution, and how you plan to use the land.

Is this tool a substitute for a professional lab test?

No. This tool provides an educational estimate of potential risk to help you decide on next steps. If you have serious concerns or this tool indicates a medium-to-high risk, we strongly recommend a professional soil test kit for accurate, scientific results.

How is the risk score calculated?

The risk score is calculated by assigning points to each of your answers. Factors known to increase contamination risk—like proximity to industrial sites or planning to grow vegetables—are weighted more heavily. The total score corresponds to a low, medium, or high risk level.
