The ‘DEF’ of Water Pollution

D

DNAPL (dense nonaqueous phase liquid), is a liquid that is more dense, and doesn’t dissolve easily with water. High concentrates of this substance can form a carpet like area on the water surface or lake or river bed. This will restrict the amount of sunlight breaking through the water and impact plants and other organisms requiring sunlight. Including the photosynthesis that produces oxygen. Liquids from chlorine will often act as a DNAPL.
