Kathmandu – A recent study conducted by the Kathmandu Metropolitan City has revealed alarming levels of fecal coliform contamination in several drinking water brands sold in the capital. Out of 21 water samples collected from various locations in Kathmandu between August 12th and 28th, 2024, 11 were found to contain harmful bacteria.

The study, which included samples from both bottled and tap water sources, was prompted by consumer complaints and targeted brands that were suspected of having poor water quality. According to the city's health department, the contaminated water samples contained colony-forming units (CFUs) of fecal coliform bacteria that exceeded the permissible limits.

Fecal coliform is a type of bacteria commonly found in the intestines of humans and animals. Its presence in drinking water indicates potential contamination from sewage or other sources of fecal matter. If consumed, it can cause a range of gastrointestinal illnesses, including diarrhea, nausea, and abdominal cramps.

The city authorities have urged consumers to be cautious when selecting drinking water and to prioritize brands with reliable quality certifications. They have also called on water suppliers to implement stricter quality control measures to ensure the safety of their products.

The Kathmandu Metropolitan City has vowed to continue its efforts to monitor drinking water quality and take necessary action against any suppliers found to be violating health standards.
