How do sources of water get polluted?
Answers
Answer:
Water pollution can be caused in a number of ways, one of the most polluting being city sewage and industrial waste discharge. Indirect sources of water pollution include contaminants that enter the water supply from soils or groundwater systems and from the atmosphere via rain.
Explanation:
Chemical waste from factories is sometimes dumped into rivers and lakes, or directly into the ground.
Pesticides (chemicals that kill insects) applied to farmland enter surface water and groundwater, often in large quantities.
Leaks from underground storage tanks for liquids like gasoline go directly into groundwater.
The sewage and wastewater that is produced in each household are treated chemically and released into the sea along with fresh water. The sewage water carries pathogens, a typical water pollutant, other harmful bacterias, and chemicals that can cause serious health problems and thereby diseases.
