The major causes of water pollution include sewage and other oxygen-demanding wastes, urbanization, agro-chemical wastes, thermal pollution, industrial wastes, nutrient enrichment, acid rain.
4. Techniques to measure economic value of ecosystem services. There are several techniques that can be used to value the benefits of improved water quality or stream restoration. If restoration of water quality or recreation occurs in an urban setting where there are residences nearby the river, the hedonic property method may be applied. due to water pollution and lack of sanitation, the overall economic loss is estimated to be 5% of the gross domestic product (UNESCO, ).
