SOURCES OF WATER AND ITS CONTAMINATION:
Water is a vital need for any life form. Some 60% to 70% of the human body is made up of water. Water fit for human consumption is called potable or drinking water. We get water from rivers, wells, lakes, springs, ponds and from rain. However, water from these sources may not be not safe to drink directly because of contamination. Water gets contaminated in various ways. For example: 1. Addition of untreated waste from industries (heat, chemicals, oil, plastic) to water bodies. 2. Use of pesticides in agriculture which affects ground water. 3. Untreated sewage waste, dead animals, waste thrown by humans into rivers and other water bodies. We can make water potable through many methods. To see a chart of contaminants and the causes, symptoms, health effects and treatment of water borne diseases visit:
