Water resources decision making in many areas, particularly arid and semi-arid climates such as the American West, depends on interannual to decadal variations in surface water availability. In addition to more predictable seasonal differences, runoff tends to exhibit long-term trends alternating between flood and drought periods. Figure 6-10 shows historical wet and dry periods based on streamflow records for 50 world rivers. For the most part, these periods are consistent on a regional basis, though they appear to alternate on a hemispheric scale.

Other examples of analgesics or their metabolites that have been found in the environment include 4-aminoantiyrine, aminophenazone, codeine, fenoprofen, hydrocodone, indometacine, ketoprofen, mefenamic acid, naproxen, propyphenazone diclofenac, ibuprofen, phenazone, gentisic acid and N-methylphenacetin. Many studies have identified these compounds in various locations around the world and in different water resources (e.g., Heberer et al. 1997, 2001a, 2001b Ternes 2001 Stumpf et al. 1999 Ahrer et al. 2001 Sedlak and Pinkston 2001 Holm et al. 1995 Ahel and Jelicic 2001 Sacher et al. 2001). 

The quality of fresh water resources in the world (river, ground or lake water) is relevant for all life on Earth. It should be noted that only 20 % of the world s population has access to good quality drinking water. The water quahty of natural water sources for hfe is affected by their origin (e.g., mountain aquifers may be contaminated in densely populated regions with industrial and agricultural activities). These numerous sources of pollution have the potential to contaminate the aquifer. 

We have described a world that strives for a constant state of equilibrium. We use our air and water resources to establish standards of living. In order to maintain those conditions, it is incumbent on us to ensure that what we extract from the environment is returned in a usable form. Inasmuch as we have no material communications beyond our planet, we are forced to work with the resources we have. We cannot destroy our water resources as we use them. We must understand that air is another finite commodity that must be returned and reused.

With a rapidly growing world population and an increasing pollution, the development of new technologies to treat water becomes a major issue for a sustainable use of water resources. Strategies for ecological water protection generally include development of new or improved industrial processes, which have no or minor effects on the nature. 

Beginning with World War II, the armed forces have carried chlorinated hydrocarbon insecticides wherever they have gone for personnel protection, premise treatment, and area control (9). Many of these compounds have been manufactured in several countries and used for disease-vector control on the land, in the home, in water resources, and directly on people by a number of international agencies, as well as by individual nations.

SaUne lakes are important environmental features, with significant geochemical impacts on ecology, water resources, and economic activity around the world. Ancient sediments within saline lake basins also offer important sedimentary archives of past climates and tectonics, because such deposits can record significant hydrologic variations.
