A Comprehensive Review of Constraints to Improved Management of Fertilizers in China and Mitigation of Diffuse Water Pollution from Agriculture
Complex and inter-related factors explain the excessive use of fertilizer observed in many intensive farming systems in China, and hence act as barriers to development of a comprehensive policy and intervention framework for mitigation of diffuse water pollution from agriculture (DWPA).
A relatively short list of reference viral, bacterial and protozoan pathogens appears adequate to assess microbial risks and inform a system-based management of drinking waters.
Water is essential to life, but many people do not have access to clean and safe drinking water and many die of waterborne bacterial infections. In this review a general characterization of the most important bacterial diseases transmitted through water—cholera, typhoid fever and bacillary dysentery—is presented, focusing on the biology and ecology of the causal agents and on the diseases’ characteristics and their life cycles in the environment
That miserable moment when you realize you’ve stepped in it: Dog poop. It can ruin you day, but pooch pollution is an even more serious, growing problem across the globe. The Environmental Protection Agency designates dog waste in the same category as toxic oils and chemicals.
In California’s San Joaquin Valley, “roughly 250 miles long and encompassing major cities, up to one in 10 public water systems have raw drinking water with uranium levels that exceed federal and state safety standards, the U.S. Geological Survey has found.
Physical evidence of neurodegenerative disease was found in the brains of some deceased Chamorro villagers and New Hampshire residents that lived on or near bodies of water that are known to contain cyanobacteria, also called “blue algae.” This alarming discovery has prompted further study into the connection between toxins in our food and water and the disorders that may occur as a result of contamination.
Drinking water contaminated by wastewater is a potential source of exposure to mammary carcinogens and endocrine disrupting compounds from commercial products and excreted natural and pharmaceutical hormones. These contaminants are hypothesized to increase breast cancer risk. We conducted a case-control study to investigate whether exposure to drinking water contaminated by wastewater increases the risk of breast cancer. Results did not provide evidence of an association between breast cancer and drinking water contaminated by wastewater.
Researchers has identified domestic sewage from hotels and camping sites on the lake’s shoreline. They said there were almost no facilities in Listvyanka to sufficiently cleanse the sewage. All samples showed chemical and microbiological contamination, including fecal.

Gusmão, Nelson Lima | Feburary 9, 2011| ScienceOPEN.com| Shared as educational material The presence of filamentous fungi in drinking water has become an area worthy of investigation with various studies now being published. The problems associated with fungi include blockage […]
The larger study tested 550 water samples collected from public and private water wells in the north Texas Barnett Shale region over a three-year period and found that the closer a water well is to a fracked gas well, the higher the concentration of contaminants including arsenic, selenium, strontium, and barium. This investigation also found “alarming” levels of benzene, a known carcinogen.
In urban Maroua, Cameroon, improved drinking water sources are available to a large majority of the population, yet this water is frequently distributed through informal distribution systems and stored in home containers (canaries), leaving it vulnerable to contamination.
Governor Rick Scott is happily spending the money elsewhere that 75 percent of Floridians voted to make a constitutional amendment to help clean up the pollution from the sugar industry that now flows directly into the Caloosahatchee River.
