What are some waterborne pollutants?
There are many sources of water contamination, including naturally occurring chemicals and minerals (for example, arsenic, radon, uranium), local land use practices (fertilizers, pesticides, concentrated feeding operations), manufacturing processes, and sewer overflows or wastewater releases.

Water pollution is commonly indicated by coliform bacteria. They are gram negative, rod shaped, anaerobic bacteria that are present in the intestines of warm blooded vertebrates like birds and mammals. Thus it is also present in the fecal matter and is also transmitted to various water bodies through it.

What are 3 examples of Bioindicators?
Microbial biomass, fungi, actinomycetes, lichens, as well as the population of earthworms, nematodes, termites, and ants can be used as bioindicators on account of their important role in nutrient cycling, specific soil fertility, soil development, and soil conservation (Anderson, 2003).
