E. coli is selected as an indicator of water potability because it is a reliable marker of fecal contamination, indicating the potential presence of harmful pathogens. It is easily detectable and quantifiable using standard laboratory techniques, allowing for quick assessment of water quality. Moreover, E. coli is typically found in the intestines of warm-blooded animals, making its presence a clear signal of environmental contamination from human or animal waste. Its absence in water suggests a lower risk of pathogenic microorganisms that can cause waterborne diseases.
What else can I help you with?
Which organisms are considered the best indicator of water potability?
Escherichia coli
Why are coliforms selected as the indicator of water potability?
Coliforms are used as an indicator of water portability because they may be associated with the sources of pathogens that contaminates the water and they can be easily cultured and detected.
Is it safe to drink bore-well water?
It may be perfectly safe but you should always get a biological test for potability.
What is a water level indicator?
A water level indicator shows how high the water is.
What has the author James E Moyer written?
James E. Moyer has written: 'Bacteriologic potability of condensate water from heat exchangers of pressure suits' -- subject(s): Water reuse, Water-supply, Space vehicles
How is well water determined safe for well users?
Users who drink the water should take a bio sample to a lab at least annually. A normal test for human potability usually costs 25-40 depending on the lab. They test for coliforms and other contaminants. It's worth it to be re-assured your water is safeUsers who drink the water should take a bio sample to a lab at least annually.

Why is water used as the universal indicator?
Water is NOT Universal Indicator. Water is often referred to as a Universal Solvent as a large number of substances are soluble in it. Universal Indicator is a chemical agent that can be used to test the pH of a liquid.
What are the advantages of numeric water level indicator using LED?
we can save water that can be wasted by overflown by the many tanks if it rings as an indicator we can save water
How can I detect a water meter leak using the water meter leak indicator?
To detect a water meter leak using the water meter leak indicator, you can observe the leak indicator dial on the water meter. If the dial is moving when no water is being used in the house, it indicates a leak in the water system.
What color does universal indicator turn in deionized water?
since water is pretty neutral, the water does not change color but the universal indicator does. The universal indicator changes color as per the quantity of deionized water... But it changes to straw color or pale yellow in 50mL of deionized water.
What colour does water turn in the universal indicator?
Water typically turns green in universal indicator. This indicates that water is neutral, neither acidic nor basic.
What happens to water when the universal indicator is added to it?
It will become orange because CO2 is an acid
