Stagnant water can be contaminated with human and animal feces, particularly in deserts or other areas of low rainfall. [2] Water stagnation for as little as six days can completely change bacterial community composition and increase cell count. [3] Stagnant water may be classified into the following basic, although overlapping, types:
These facilities tend to have a higher concentration of animal manure, which when stored improperly can cause problems by leaking into local groundwater and aquifers, causing groundwater contamination. Under the Clean Water Act, AFOs are considered a point source of pollution and are held to specific standards by the United States ...

Contaminants of emerging concern (CECs) is a term used by water quality professionals to describe pollutants that have been detected in environmental monitoring samples, that may cause ecological or human health impacts, and typically are not regulated under current environmental laws.
