1. Industrial sewage pollution caused by water pollution The discharge of industrial wastewater is the main source of water pollution in China. Since the reform and opening up, the country has vigorously developed industry and taken economic construction as the center. At the cost of sacrificing th...
In the actual contaminated sites, aquifer lithology, groundwater hydrodynamics and chemical composition have an important impact on the remediation of Cr(VI) pollution in nano-iron reaction zone. Therefore, the effects of aquifer medium particle size, groundwater flow rate and ionic strength on the...
municipal corporations into waterbodies. Most of the water supplied by municipal authorities in urban areas is unsafe to drink and requires further decontamination from heavy metals, virus, cysts, bacteria, and other toxins. Industrialization is expected to rise, leading to increased water pollution ...
Water pollution is the release of substances into bodies of water that makes water unsafe for human use and disrupts aquatic ecosystems. Water pollution can be caused by a plethora of different contaminants, including toxic waste, petroleum, and disease-causing microorganisms. What human activities ca...

Well our point of pollution “pod technology” water treatment systems solve THAT, but how do we convert enough businesses to become recyclers rapidly? And that’s where Water On Demand and Kevin Harrington come into the picture — creating an “army of us” could make that possible. What’...
Thermal pollution is any discharge that will dramatically alter the temperature of a natural water source 48. This pollution commonly comes from municipal or industrial effluents 1. If the temperature of discharge is significantly warmer than the natural water, it can negatively affect water quality....
This paper charts the decline in the quality of Japan's water resources from about 1955, and the increasingly energetic measures taken to reverse the trend. The standards set by the Basic Law for Environmental Pollution Control are described, and their impact to date is assessed. With respect ...
