The presence or absence of the indicator or of an indicator species or indicator community reflects environmental conditions. Water Pollution: Causes & Effects, Eutrophication, Algal Blooms (this post) Water Pollution Control Measures: Bio-Toilets, Bioremediation (next post) Water Pollution Water pollution is the addition/presence of undesirable substances to/in water such as organic, inorganic, biological, radiological, heat, which degrades the quality of water so that it becomes unfit for use’. b.
