In Egypt, nineteen water springs with temperatures exceeding 35 degrees C, which can be considered thermal waters, were reported. The radiological aspects of thermal water in three northern regions of Egypt (Gulf of Suez, Cairo, and Bahariya Oasis) were investigated. The activity concentrations of natural radionuclides of 226Ra, 40K, total uranium and 210Pb (210Po) in water samples were determi...
Acquisition of sporadic community-acquired legionnaires' disease has been linked to hot springs and whirlpool baths. Outbreaks of hot spring-associated legionnaires' disease were reported in Japan in the last few years. Although the mode of transmission is unclear, the presence of Legionella in hot springs may discourage hot springs resort visits by the general public. An environmental survey w...
South Africa has numerous thermal springs that represent topographically driven meteoric water migrating along major fracture zones. The temperature (40-70°C) and pH (8-9) of the thermal springs in the Limpopo Province are very similar to those of the low salinity fracture water encountered in the South African mines at depths ranging from 1.0 to 3.1 km. The major cation and anion composition o...
Background and Objective: Scaling and corrosion both are destructive to materials (usually metals) in water supply systems. A dataset (from 2002 to 2013) of groundwater resources (including springs, qanats, deep wells and semi-deep wells) were examined for water tendency to corrosion or scaling in rural regions of Kashan, a city in Isfahan, central Iran. Materials and Methods: Water quality pa...
BACKGROUND In the sub-urban areas of Kampala city, springs are a major source of water for domestic use. Though spring water is considered to be aesthetically acceptable for domestic use, presence of poorly designed pit latrines, poor solid waste management as well as poor and inadequate spring protection, may lead to contamination of spring water with pathogenic bacteria. OBJECTIVES The obje...
To survive cold winter periods most, if not all, Florida manatees rely on warm-water refuges in the southern two-thirds of the Florida peninsula. Most refuges are either warm-water discharges from power plant and natural springs, or passive thermal basins that temporarily trap relatively warm water for a week or more. Strong fidelity to one or more refuges has created four relatively discrete F...
Due to the lack of adequate sources of drinking water and uncertainty about the quality of these sources, along with rising water demand due to population growth, it is important to find a suitable solution to supply drinking water. Rainwater harvesting from roofs and use of natural discharge from springs are among techniques which can replace surface and underground water resources. The city o...
