, 1994 In this chapter, I will discuss infections acquired in nonmarine environments. Both natural fresh waters (lakes, ponds, rivers, streams) and manmade aquatic environments (swimming pools, hot-tubs, whirlpools, spas) may serve as the origin for numerous pathogenic microorganisms.

Fresh water has been used by humans from earliest times, at first only for drinking, but later for fishing and navigation. The majority of settlements in many countries are related to spring lines and other sources of pure water. With improving sanitation, water was used for cleaning and removing domestic wastes, as well as for irrigation in ...

Availability of fresh water [PDF]
, 1992 Fresh water is essential for human survival and for the maintenance of ecosystems on land. It is a key factor in development, particularly in arid and semi-arid countries where water security, like food security, is an important issue. However, concern is also growing in more humid countries where competition between the different sectoral users of ...

American Antiquity, 1961
AbstractBecause fresh-water dams are flooding areas faster than archaeologists can investigate them, it has become urgent to develop a method of underwater archaeological research. Some technical equipment, such as “scuba” and other devices used by amateur divers, is already available. This, together with specialized techniques, some already developed,

Journal of the Atmospheric Sciences, 1969
Abstract Photographic observations of the whitecap coverage of large fresh water lakes were made in conjunction with measurements of wind velocity, and air and surface water temperatures. The fraction of the water surface covered by whitecaps shows an abrupt increase as the wind velocity increases from ∼7 to ∼8 m sec−1.

WIREs Water, 2019
In an era increasingly focused on the question of how to value fresh water, this essay argues that questions of value cannot be parsed apart from the multiple ontologies that undergird those value judgments. Returning to Nelson's observation that water exists “in a metaphysical blindspot,” this essay describes what chastened metaphysics have to do with
