We studied the physical, chemical, and microbiological factors that influence drinking water quality processed from River Tigris, and of the three main drinking water purification stations located at different parts of Tigris River, along with evaluation of drinking water of Al-Shula region in Baghdad city. Water samples were taken monthly from December 2009 to September 2010. Physical and chem...

Dhaka, Bangladesh’s capital is one of the foremost inhabited megacities globe. Management and development sustainable safe water supply for city dwellers are completely dependent on ground river availability. The previous years, it has been reflected that Dhaka experiences shortage in some areas during dry season Rainwater harvesting can be an efficient strategy reducing present crisis minimizi...

RIVERA, F., ORTEGA, A., LÓPEZ-OCHOTERENA, E. & PAZ, M. E. 1979. A quantitative morphological and ecological study of protozoa polluting tap water in Mexico City. Trans. Amer. Micros. Soc., 98: 465469. The stiidy was performed using samples obtained from the tap water of the most populated area of the Federal District in Mexico City. The organisms were concentrated through filtration procedures ...

Inhalation of potable water presents a potential route of exposure to opportunistic pathogens and hence warrants significant public health concern. This study used qPCR to detect opportunistic pathogens Legionella spp., L. pneumophila and MAC at multiple points along two potable water distribution pipelines. One used chlorine disinfection and the other chloramine disinfection. Samples were coll...

-The aim of the Proposed Project is a Microcontroller based Low-Cost Sensor Network for Real-Time Monitoring and Contamination Detection in Potable and nonPotable Water Distribution Systems and also updates the information to the consumers and concerned authorities by using GSM module. In the existing system, it is just monitor the water level and electrical conductivity manually (off-line) and...

Motivation and Vision Assessment of damage to lifelines after natural disasters, such as earthquakes, tsunamis, or hurricanes, is a crucial component of emergency response and rescue efforts. Of particular importance are clean water delivery systems, as water is the single most important survival resource; failure to detect damage in water pipelines can lead to contamination and epidemic outbre...

UNLABELLED Power toothbrushes (PTBs), in combination with abrasive dentifrices, may encourage wear of dental cements at crown margins. PURPOSE This study's purpose was to determine the effect chemical cleaning had on the microbial quality of water emitted from dental unit waterlines (DUWL), 3-way syringes, and power scalers. METHODS Ten randomly selected dental units with attached self-cont...

This study investigated a small subset of the two community water-disinfection systems--hypochlorinators and tablet feeders-in rural Honduras. Levels of residual chlorine were assessed at three locations within the distribution system: the tank, the proximal house, and the distal house. The levels of residual chlorine were compared with the standard guidelines set by the Pan American Health Org...
