Groundwater is hydrologically divided into: 1) Vadose water
in the unsaturated zone, and 2) Water in the zone of saturation.
He strives to be readable and yet avoid the vice of oversimplification; thus along with, for instance, chapters about the hydrologic cycle, aquifers, and contemporary groundwater supply issues, there are also chapters on vadose water
and phreatic water and applied hydrogeology.

Afforestation of the slope would lead on the one hand to retention of the vadose water
and on the other hand to drawing the underground water to the surface.
Chapters cover the water cycle, groundwater, use of groundwater, vadose water
, flowing water, erosion and sedimentation, lakes, water freezing, dams and reservoirs, wetlands, microscopic life, and atmospheric water.
The El Nino phenomenon and the Philippine volcano Pinatubo have affected weather patterns worldwide, and are the direct cause of at least one unusual mineral occurrence: orthoserpierite crystallizing from vadose water
surfacing on the usually dry Arizona desert.
The health risk due to microbial movement through soil depends on the proximity to drinking water sources and the dilution of the microbes that occur in the vadose water
