The purpose is to avoid consumers infection.
hi there you you can add a water purefying machine to your taps and filter out bacterial contaminates,cholrine,fluride ect . this will make your water very clean and contaminat free for human consumption if you want to find out more info here trevordye.org Thanks trevor dye
Biological contamination of water is when microbes are present in drinking water. This makes it unsuitable for drinking as it can make you sick.
Pure water and most chlorinated drinking water lacks the nutrients needed for bacterial growth. If the water is left uncovered though enough dust may get into the water for some bacterial growth.
Organisms commonly used as indicators of bacterial contamination include coliform bacteria, particularly Escherichia coli (E. coli), and enterococci. These microorganisms are typically found in the intestines of warm-blooded animals and can indicate fecal contamination in water or food. The presence of these indicators suggests that pathogens may also be present, posing potential health risks. Monitoring these organisms helps assess water quality and public health safety.
The chemical oxygen demand (COD) of drinking water is typically low, ranging from 1 to 5 mg/L. This value indicates the amount of oxygen required to oxidize organic and inorganic matter present in the water. High COD levels in drinking water can indicate contamination and the presence of pollutants.
To check for sulbe tested is filled sulphide ion contamination of drinking water, the water to be tested is filled in a bottle with a H2S strip. This sample is put in an incubator for 16 hours. If the test strip comes back black, the water is not fit for consumption.

The presence of Entamoeba histolytica in drinking water indicates the contamination of water or we can say that water pollution.
To ensure the safety of drinking water and remove lead contamination, it is important to regularly test water sources for lead levels, replace lead pipes and fixtures, use water filters certified to remove lead, and educate the public on the risks of lead exposure in drinking water.
Biological contamination of water is when microbes are present in drinking water. This makes it unsuitable for drinking as it can make you sick.
Boiling water after a flood is recommended to kill any harmful bacteria, parasites, or viruses that may be present in the water due to contamination from floodwaters. This helps to make the water safe for drinking and prevents potential waterborne diseases.
Contamination of waterways and drinking water, potential chemical residues.
i dont know can you say

Bacterial gastroenteritis is frequently a result of poor sanitation, the lack of safe drinking water, or contaminated food--conditions that are common in developing nations.
Assuming the question is "What is potable water pollution" it is the contamination of a drinking water supply by a material that makes it toxic, or taste or smell bad.
