unusual sights happened recently‚ such as Yangtze River turns blood red in Chongqing. Water pollution in China are usually triggered as accidents. Uncontrollable wastewater discharges are usually caused by the inadequate wastewater storage and sewage treatment facilities. Industrial wastewater outflows‚ and such accidents lead to reduction of fresh drinking water supply as the fresh water is used to dilute the pollutant released immediately. The causes of degradation of fresh drinking water level

Since all natural waterways contain bacteria and nutrients‚ almost any waste compounds introduced into such waterways will initiate biochemical reactions (such as shown above). Those biochemical reactions create what is measured in the laboratory as the Biochemical oxygen demand (BOD). Such chemicals are also liable to be broken down using strong oxidizing agents and these chemical reactions create what is measured in the laboratory as the Chemical oxygen demand (COD). Both the BOD and COD tests
