So, most of the assays of water purity are more focused on detecting faecal contamination which is assessed by surviving of the presence of the faecal contamination.

If we see the assay of water purity, it is more focused on detecting faecal contamination which is assessed by surveying for the presence of, we have given options enteroviruses, option b protozoans, option c cysts, option d endospores and option e indicator bacteria.

So, if we see the assay of purity of water, the surveying for a specific pathogen can be very difficult and time consuming.
01:54
Therefore, we can focus on detecting the faecal contamination.

So, if we see the answer, it will be out of this option, the correct answer will be indicator bacteria...
