Water Resources and Water Pollution

Leonardo da Vinci declared water to be the blood of Earth and Earth’s rivers its veins. How perceptive, for without water, life might not exist on Earth, and it certainly would not have the tremendous complexity and diversity that we see!

In this chapter we’ll look at several aspects of this crucial resource, including its unique properties, the places it occurs and how it moves from place to place (which is essentially the water, or hydrologic, cycle), and water’s status as a resource. We’ll study water pollution, the serious blood disorder of Earth, and what we can do to heal this disorder through water management.

This is the familiar water cycle diagram that shows the relationships between precipitation, glaciers, runoff, infiltration, groundwater, evapotranspiration , condensation, and more. It was published by the USGS, or US Geological Survey, in 2000.
Figure 14.0.1.The recently retired USGS Water Cycle Diagram, first published in 2000. This chapter will incorporate the new diagram. Stay tuned!
