What should be included in an environmental site assessment to ensure comprehensiveness?

A comprehensive environmental site assessment is essential for identifying potential environmental liabilities related to a property. Including both current and historical usage data is crucial because it provides a complete picture of how the property has been used over time and helps identify any possible contaminants. Current usage data alone might not reveal past activities that could have led to contamination, such as previous industrial operations, waste disposal practices, or other activities that ceased long ago but have left lasting impacts on the environment.

Historical usage data sheds light on past management practices and land uses, which can significantly affect the property’s present condition. Understanding the history of the site allows assessors to evaluate potential contaminants, choose appropriate testing methods, and implement risk management strategies. By combining both current and historical information, an assessor can better evaluate risks and develop a more thorough understanding of the site's environmental context. This holistic approach is vital for making informed decisions about property management and mitigation measures.
