waste, toxic, pollution, disease, environment


The issue of sewage disposal has become one of the biggest problems facing the entire world, due to the many health and economic risks that this entails. This type of polluted water includes many dangerous pollutants, whether they are organic or chemical materials (such as soap and industrial detergents), some types of harmful bacteria and microbes, in addition to toxic heavy metals and carbohydrates. Wastewater or sewage water is liquid waste or water whose quality has been negatively affected as a result of human influence. It includes effluents discharged from residential, commercial, industrial and agricultural complexes, and may also contain a wide range of potential pollutants in different concentrations. The large amounts of water produced from mine drainage, mine cooling, hydroextraction, and other mining operations increase the potential for these chemicals to contaminate surface water. In well-regulated mines, hydrologists and geologists make accurate water and soil measurements to rule out any kind of water pollution that could be caused by mining operations. Reducing or eliminating environmental degradation in modern American mining is implemented by federal and state law by restricting operators to meet standards for protecting surface and ground water from pollution. It also refers to the general term, to the liquid waste issued by human complexes and containing a wide range of pollutants resulting from the mixing of liquid waste from various sources.
