Trace elements levels in sediments of the Czech part of the Elbe river

Large segments of the world's people have elected to live where water meets land, or very near to those places. Water has a multitude of attractions to people, such as transport, power, recreation, and industrial and domestic supply. Most importantly it is essential to life. Our water supply must be fresh (non-salt), safe (free of contaminants), and be available in an adequate supply. This lesson is based on the scientific article by Philip P. Micklin entitled Man and the Water Cycle: Challenges for the 21st Century in this issue of GeoJournal. These challenges include the provision of a safe and reliable water supply throughout the world. The global issue of safe water, and access to that water is the main focus of this activity.
