Geologists study the earth. And 71 percent of the earth is water. So that means they probably study water often. So they must be experts on water. At least some of them are. They are also called earth scientists. Geologists are engaged in exploration for mining companies in search of metals, oils, and other Earth resources. They are also in the forefront of natural hazards and disasters warning and mitigation, studying earthquakes, volcanic activity, tsunamis, weather storms, and the like; their studies are used to warn the general public of the occurrence of these events. Currently, geologists are also engaged in the discussion of climate change, as they study the history and evidence for this Earth process. All of these except for earthquakes have to do with water. So geologists do have a big impact on water. James Hutton is often viewed as the first modern geologist. Not counting caveman.
The first geological map of the U.S. was produced in 1809 by William Maclure.[2][3] In 1807, Maclure commenced the self-imposed task of making a geological survey of the United States. Almost every state in the Union was traversed and mapped by him; the Allegheny Mountains being crossed and recrossed some 50 times.
