The presence of a port, such as the one illustrated in the photo, indicate the presence of an underground tank. Contact the property owner to determine what the port is or was used for. If there is or was an underground tank, determine what was stored in the tank and determine if any contamination occurred as a result of the tank leaking, being excavated, etc.
