This source of freshwater, vital for the expansion of inland communities, dates back nearly 10, years — 3, years before the wheel was ever imagined. The well is but one of a long list of innovations in water technology that have enabled human development to continue apace. Sophisticated pipeline networks and treatment plants today furnish us with this elixir of life and industry.
MRSA is a well-known problem in hospitals, where patients have picked up potentially fatal bacterial infections that do not respond to antibiotic treatment. But since the late s, it's also been showing up in otherwise healthy people outside of health-care facilities, prompting a search for sources in the wider community.
Sapkota, assistant professor in the Maryland Institute for Applied Environmental Health and research study leader. Sewage plants are one possible source, because infected people can shed MRSA through their feces, as well as from their nose and skin.
|Volume 23 - 2001||July 4, UsefulResearchPapers Research Proposals 0 Wastewater treatment is the process of the reasonable utilization and purification of wastewater with the help of various means. Wastewater is quite a dangerous substance, because polluted water is harmful for the human health, the life of animals and fish.|
|Cause x26 effect essay||Other nonpotable applications include cooling water for power plants and oil refineries, industrial process water for such facilities as paper mills and carpet dyers, toilet flushing, dust control, construction activities, concrete mixing, and artificial lakes. Although most water recycling projects have been developed to meet nonpotable water demands, a number of projects use recycled water indirectly for potable purposes.|
The resistant bacteria have been detected before in wastewater plants in Sweden, but researchers at UM's School of Public Health say this study, conducted in parnership with the University of Nebraska Medical Center, is the first to spot it in US facilities.
Their findings were published in the November issue of Environmental Health Perspectives.
Researchers at the two schools collected wastewater samples at two Mid-Atlantic and two Midwestern treatment plants, which were not identified in the paper. They said they chose the plants, in part, because treated effluent from these plants is reused as "reclaimed wastewater" and sprayed on fields to irrigate and fertilize them.
The researchers wanted to see if MRSA could be spread that way. The study found MRSA in 83 percent of the raw sewage entering the plants, but the incidence declined as the sewage progressed through the treatment process.
Only one plant still had the bacteria in its fully treated water, researchers found, and that facility did not regularly use chlorination to finish disinfecting its wastewater.
A recent study in the Netherlands led by researchers from Johns Hopkins' Bloomberg School of Public Health found the risks of getting MRSA there highest among people living in a region with high concentrations of cattle and pigs.1 Wastewater production, treatment and use in India R Kaur1, SP Wani2, AK Singh3 and K Lal1 1 Water Technology Centre, Indian Agricultural Research Institute, New Delhi, India 2 International Crops Research Institute for the Semi-Arid Tropics, Hyderabad 3 Indian Council of Agricultural Research, New Delhi, India Email: [email protected]; [email protected] The Research.
