Water pollution is caused by oil spill, acid rain, and urban runoff. The use of hazardous chemicals in manufacturing industries and agriculture cause severe water pollution as waste from these industries goes directly into nearby rivers, lakes and ponds without getting treated to remove harmful toxins and compounds. This not only affects the quality of water but also pose danger to several endangered aquatic species. Increase in the water pollution can badly affect marine life and their habitats. Poor people who do not have access to clean drinking water are forced to drink untreated water which makes them prone to water related diseases which directly affects their health. Chemicals in water such as pesticides, nitrates, lead and arsenic can be a threat to human health. Pesticides can damage the nervous system and cause cancer because of the carbamates and organophosphates that they contain. Chlorides can cause reproductive and endocrine damage. Second, nitrates are especially dangerous to babies that drink formula milk. It restricts the amount of oxygen in the brain and cause the “blue baby” syndrome. Third, lead can accumulate in the body and damage the central nervous system. Lastly, arsenic causes liver damage, skin cancer and vascular diseases.
