How can urbanization affect water sources?
1 Answer
Urban areas are mostly contaminated areas.
Explanation:
Urban areas have dense traffic, dense small and medium type industries, lots of pollutants due to heating systems (such as dust, carbondioxide, hydrocarbons, sulfur oxides, nitrogen oxides, etc.).
Water sources in urban areas get lots of pollution. Groundwater sources are contaminated due to fuel (gas) stations, small industries (if their tanks are leking), etc. Surface water contamination occurs especially when wet conditions (rainfall) exist.
Furthermore, wetlands get lots of contaminants via different pathways. That is why we do not see lots of creatures (rich biodiversity) in such contaminated places.
