Sources of Pollution: Drought


Drought is a very dry condition caused by a lack of rainfall.


How does this cause Non-Point Source Pollution?

During drought, dissolved chemicals such as salts, sulfates, and chlorides become concentrated and can be toxic to plants and animals or cause dehydration of plants and animals.  For instance, drinking water intakes may be closed during a drought if salinity and chlorides increases too much because they can cause health problems for people and production problems for industry.
