Escherichia coli
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.
It may be perfectly safe but you should always get a biological test for potability.
A water level indicator shows how high the water is.

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.

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.
we can save water that can be wasted by overflown by the many tanks if it rings as an indicator we can save 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.
It will become orange because CO2 is an acid
A double indicator is used to find the alkalinity of the water sample to prevent errors.
