The tanks had held fuel oil for the houses' furnaces, and had been at some point abandoned. Usually one pumps out any remaining oil, due to the risk that the tanks will begin leaking oil into the groundwater. Remediation can be extremely expensive, as all the contaminated soil needs to be dug up and disposed of according to regulations.
I of course wished there was a way to take advantage of the hole--perhaps lay pipes in it before refilling, to be used later on for geothermal heating of the house. But there was no time for such planning.
