Drinking Water
Drinking water, or potable water, is water safe enough for human consumption (drinking and food preparation) without risk of immediate or long-term health hazards. It must meet specific microbial, chemical, and physical quality standards, usually defined by regulatory guidelines (e.g., WHO, EPA) to be free from pathogens and toxic substances
Acceptable standards of drinking water
Reference: WHO standard of microbial quality of Drinking Water (2024)
World demography of E coli infection through unsafe Drinking Water
- In 2022, globally, at least 1.7 billion people use a drinking water source contaminated with faeces. Microbial contamination of drinking water because of contamination with faeces poses the greatest risk to drinking-water safety.
- Mortality and Morbidity: Around 1.5 million deaths occur annually due to waterborne diseases. Roughly 829,000 deaths (including 200,000+ children) are attributed to diarrhea
Critical parameters related to microbial safety (all supplies) |

Parameter | Significance for microbial water quality | Occurrence in drinking-water |
|
E. coli (or alternatively thermotolerant coliforms) | E. coli is excreted in large numbers in the faeces of humans and other warm-blooded animals. While most strains are non- pathogenic, certain strains can cause acute diarrhoea. E. coli is an important indicator of the presence of recent faecal contamination and associated pathogens | Higher E. coli concentrations are expected in surface water and shallower groundwater sources (including those under the influence of surface water). Lower concentrations are typically found in deeper groundwater sources that are protected. |

Overview of pathogenic stains in Drinking water
Drinking water test must meet both chemical and microbial criteria to be fit for drinking as well as food preparation purpose. Microbial criteria is of high importance as it deals directly live harmful microorganism which which has immediate health effects on Human being. According to WHO Drinking water standard , total coliform and E. coli should be absent in Drinking water.
Coliforms: Includes Escherichia, Klebsiella, Enterobacter, and Citrobacter.
Escherichia coli (E. coli) is a specific species within this larger coliform group that is the most reliable indicator of recent fecal contamination.
Fecal (Thermotolerant) Coliforms: A subset that can grow at elevated temperatures (44.5°C). They are more specifically associated with the digestive tracts of humans and animals
Types of E.coli Pathogenic stains
· Shiga toxin-producing E. coli (STEC/EHEC): The most dangerous strain, including O157:H7, producing toxins that cause severe bloody diarrhea and hemolytic uremic syndrome (HUS).
· Enterotoxigenic E. coli (ETEC): Known as "traveler's diarrhea," it causes watery diarrhea by producing toxins, commonly from contaminated food/water.
· Enteropathogenic E. coli (EPEC): Causes diarrhea, particularly in infants, by damaging intestinal microvilli.
· Enteroinvasive E. coli (EIEC): Causes fever and dysentery-like diarrhea by invading the intestinal mucosa.
· Enteroaggregative E. coli (EAEC): Causes persistent diarrhea, often in children and HIV patients, by adhering to the intestinal surface.
· Diffusely adherent E. coli (DAEC): Associated with diarrhea, adhering to the entire surface of epithelial cells.
· Uropathogenic E. coli (UPEC): Causes urinary tract infections (UTIs) and meningitis.

Highlights on importance of drinking water test at home
Due to consumption of fecally contaminated water, there is huge loss of lives according to governing authority data like WHO, EPA etc. These lives can be saved by providing little effort by testing the quality of drinking water by consumer itself at home. Government agency working in sector like safe drinking water for consumers can run programme like testing of water quality at home using home test kit. Many companies are providing Test kit for test of drinking water which are reliable and give accurate result at house hold level and consumers willing to do so can test their drinking water at home by paying minimal cost. Moreover testing of drinking water at reference laboratory is time consuming.
Safe house drinking water test kit can be solution for testing drinking water at home and saves many lives due to consumption of fecally contaminated water.
Choice is yours: one-steps towards healthier future and revolution against fecally contimanition water consumption death control.
