When removing a tank, how many soil samples should be collected?

When removing a heating oil tank, collecting two samples, one from each end of the excavation area, is crucial for ensuring a thorough assessment of any potential contamination. This approach allows for the evaluation of the soil both at the front and back of the tank location, which are often areas where leaks or spills are most likely to occur. By focusing on the two ends, you can capture a representative understanding of any contaminants that may have migrated from the tank during its operation.

This method aligns with best practices in environmental assessments, which emphasize the importance of obtaining soil samples that represent the highest potential risk areas. Collecting samples from both ends provides a balanced view of the contamination that could be present as a result of the tank's functionality and potential leaks. It is important for compliance with environmental regulations and for assessing the need for remediation efforts.
