Abstract:
Pakistan is ranked 80th out of 122 countries in terms of drinking water
quality. Coliforms, harmful metals, and pesticides are found in drinking water sources
around the country, including surface and groundwater. Various WHO guidelines are
routinely broken. Typhoid, giardiasis, intestinal worms, diarrhea, cryptosporidium
infections, and gastroenteritis are all waterborne illnesses in Pakistan. According to
the Intergovernmental Union for Conservation of Nature (IUCN), Pakistan has the
highest rate of infant fatalities due to water-related diarrhea in Asia, at 60%. So, this
study aims to determine the drinking water quality at Tench Bhata Rawalpindi
district, Pakistan. It investigates whether the drinking water quality parameters are
within the WHO permissible limits or not.
In this research, physical, chemical, biological, and Heavy metals analysis of
water samples collected from different locations of Tench Bhatta Rawalpindi district,
Pakistan were studied. 35 points were selected for drinking water samples through the
city distribution system, according to the city map. Samples were collected in
sterilized plastic bottles for analysis. The Physical parameters were measured using a
Multi Parameter Tester. Chemical parameters were calculated by standard methods,
Levels of some Heavy metals were determined by Atomic Absorption Spectroscopy.
These results suggest that Some indicators were found to be outside of WHO's
allowed limits, putting consumers at risk. The residents in the area were found to be
unaware of the drinking water's quality. People discard their rubbish in open areas
near water sources. There are no water treatment facilities. When it rains, the water
turns murky, and as it flows down the hill, it picks up a variety of impurities.
