Many industrial sites produce waste in the form of toxic chemicals and pollutants, and some don’t have proper waste management systems in place. Sometimes, industrial waste is dumped into nearby freshwater systems.
Detailed explanation-3: -In addition to the release of hazardous chemical pollutants, the industries may also cause thermal pollution and noise pollution.

Detailed explanation-4: -The types of water pollution include: Groundwater Pollution. Surface Water Pollution.
Detailed explanation-5: -Global warming. Rising global temperatures caused by CO2 emissions heat the water, reducing its oxygen content. Deforestation. Industry, agriculture and livestock farming. Rubbish and faecal water dumping. Fuel spillages.
