Humans have long been fascinated by the dynamism of free-flowing waters. Yet we have expended great effort to tame rivers for transportation, water supply, flood control, agriculture, and power generation. It is now recognized that harnessing of streams and rivers comes at great cost: Many rivers

We often reach conclusions partially on the basis that we do not have evidence that the conclusion is false. A newspaper story warning that the local water supply has been contaminated would prevent a person from drinking water from the tap in her home. This suggests that the absence

Routine environmental culture of the hospital water supply for legionella has proven to be an important strategy in prevention. Documentation of legionella

Examples for use of this stream classification system for engineering, fish habitat enhancement, restoration and water resource management applications are presented

Abstract: The objective of this study was to investigate the frequency of contamination of Legionella in the King Fahd Hospital of the University (KFHU) cooling tower water of air conditioning system and other water supplies. A total of 300 samples were collected from various sites in KFHU. Water
