perspectives. This will become clearer when we move on to explore the presence, migra-
tion, and persistence of contaminants in urban areas.
Water is a very good solvent and has the ability to dissolve and erode substances
and materials at the surface and below. Water can transport these substances and materi-
als great distances. An appropriate quote heard in geological circles states, “Water destroys
everything that the Earth creates and puts it in the oceans (reference source unknown).”
The next chapter applies the principles learned from Chapters 2 and 3 to the geo-
logic investigations performed at specific urban sites. These investigations are called
Environmental Investigations and are conducted across a broad array of urban regions in
the United States at thousands of properties every year.
