Water quality in developing countries
Although more than two-thirds of the earth's surface is covered with water, only 0.007 % can directly be used as drinking water. According to WWF, over 780 million people do not have access to clean drinking water. The situation in developing countries is particularly difficult, because the amount of water wells and tanks is not enough. Also the quality of the water is a cause of concern.
In developing countries, 90 % of waste water and 70 % of industrial waste are transported directly into water and contaminate the drinking water reservoirs1. In addition, most of water treatment plants are completely overburdened2. In some cases the water there is extremely contaminated by salts, metals, nutrients, pesticides and microorganisms3. This burdens arise from industry and household wastes, wastewater and improper agricultural practices. Increasing water scarcity and deteriorating water quality are important international challenges.
"Every 15 seconds, a child dies in the developing countries due to diarrhea, which is usually caused by dirty water", said Dietrich Garlichs, CEO of UNICEF Germany.
