polluted water
Dirty polluted water is ever present in countries that have poor hygiene and insufficient sanitation. International travelers who visit developing countries or adventure seekers, who often rely on surface water in any country, including the United States and European countries, are at risk from contracting waterborne diseases such as diarrhea, cholera, typhoid and amoebiasis. Worldwide, especially in developing countries, the absence of inadequate sanitation and the pressing issues like over-population and uncontrolled pollution, means that water may be infected with human waste and even urban tap water may become contaminated even with the presence of proper water treatment systems. Primarily humans, but also animals, are the source of microorganisms that contaminate water sources and cause intestinal infections.
