What action must a certified contractor take concerning soil contamination?

The requirement for a certified contractor to always conduct a soil test before proceeding with any remediation or construction activities is crucial for multiple reasons. Initially, testing ensures that the contractor accurately assesses the level of contamination in the soil. This is essential for determining the appropriate remediation methods needed to mitigate the health risks posed by asbestos fibers and other contaminants.

By performing a thorough soil test, the contractor can identify the specific types of contaminants present, their concentration, and the extent of the affected area. This information is critical for complying with environmental regulations and for developing a safe and effective action plan.

In contrast, simply covering contaminated soil with a tarp or removing visible debris without proper testing does not address potential hidden hazards. Encapsulating contaminated areas might be a viable method under certain conditions, but without initial soil testing, the contractor cannot gauge whether encapsulation is sufficient or whether more comprehensive intervention is needed. Taking a proactive approach through testing helps ensure that all health and regulatory requirements are met, thereby safeguarding public health and the environment.
