Final answer:
A Phase I environmental assessment includes procedures such as site inspection and title research, but does not typically include pollution cleanup, which is part of later phases if required.
Step-by-step explanation:
A Phase I environmental assessment is a preliminary evaluation conducted to identify potential environmental liabilities associated with a property, principally for real estate transactions. The assessment includes a site inspection, to observe current conditions and past uses of the property, title research, to identify historical property usage and environmental liens, and other procedures like reviewing regulatory databases and interviewing past and current owners. However, it does not typically include pollution cleanup, which is an action taken after the presence of contamination has been confirmed and usually falls under Phase II or III of environmental site assessments. Procedures like hydrology studies may be a part of a more detailed assessment if the initial Phase I identifies potential concerns relating to water on the site.
