These include finding symptoms of damage to aquatic plants and animals such as dead fish , finding chemicals in the water, comparing the previous history of the quality of water with the present quality, and getting complaints from water users. Radioactive contamination , resulting from 20th century activities in atomic physics , such as nuclear power generation and nuclear weapons research, manufacture and deployment. Leachate is a highly concentrated liquid pollutant that may contain toxic chemicals and pathogenic micro-organisms as well as high levels of organic compounds. Manufacturing industries release thermal energy into the air as well as into bodies of water. When chemicals from such wastes leach into the soil or enter the water bodies, they cause soil contamination and water pollution. George's University, St.
