Further increasing our knowledge about mountain water resources will help us to understand the interaction between mountains and lowlands. It is this interaction that needs to be accorded high priority in terms of watershed management and in the interests of mitigating any conflicts that may arise over the distribution of this precious resource.

According to the British North America Act of 1867, the Canadian legislative base for drinking water derives from the constitutional distribution of powers between the federal and provincial governments. Although this act does not deal specifically with water resources and therefore drinking water supply, judicial interpretation over the years has resulted in a situation in which drinking water is a shared federal-provincial jurisdiction.

The third major water resource study involved 76 reservoirs located in 11 midwestem states. These studies determined the occurrence and temporal distribution of herbicides and their degradation products in the outflow from selected reservoirs in the upper Midwest they also explored whether the occurrence of herbicides in the reservoir outflow could be related to drainage-basin characteristics, water and land use, herbicide use, and climate. It was found that reservoirs are repositories for herbicides from midwestem streams and that herbicides and their degradation products were detected more frequently throughout the year in reservoirs than in streams. Reservoirs hold runoff from cropland causing herbicide concentrations to decrease downstream, and they dampen the pulse of herbicides that occur during the spring flush.

This chapter has outlined the main effects of arsenic and selenium on human and animal health, their abundance and distribution in the environment, sampling and analysis, and the main factors controlling speciation and cycling. Such information should help to identify aquifers, water resources and soils at risk from high concentrations of arsenic and selenium, and areas of selenium deficiency. Human activity has had, and is likely to continue to have, a major role in releasing arsenic and selenium from the geosphere and in perturbing the namral distribution of these and other elements over the Earth s surface.

The U.S. Geological Survey collects, interprets, publishes, and distributes data about the physical and geologic features, minerals, mineral fuels, and water resources of the United States, its territories, and possessions. Survey reports are of two main types book reports (professional papers, bulletins, water-supply papers, and circulars), and maps.
