From a NYT weekly jobs column, we learn of one employment area experiencing high growth:

[D]emand for hydrologists has been predicted to grow 24 percent from 2006 to 2016, much faster than the average for all occupations, according to the Bureau of Labor Statistics.

Hydrologists study the distribution, circulation and physical properties of water, with hydrogeologists focusing specifically on groundwater.

After creation of the Environmental Protection Agency…, hydrologists’ work was largely focused on water quality. Today, however, “an increasing percentage of hydrologists are interested in water quantity and supply, which is an emerging issue and where global climate change plays a big role,” said Dork Sahagian, professor of earth and environmental science at Lehigh University and director of its Environmental Initiative in Bethlehem, Pa.

“But concern with water quality — which involves local, site-based issues — still drives the job market,” he said. “Most hydrologists in this part of the world are still hired to cope with the availability of clean water for drinking and municipal supplies.”

With industrial chemicals like BPA contaminating our drinking water supplies which are then being squeezed both by agricultural needs and by climate change-induced droughts, the future hydrologists of the world will never lack for stuff to do.
