Abstract:
Physical and aesthetic parameters of drinking water include total dissolved solids, electrical conductivity (EC), taste, odour, colour and turbidity. Although these parameters are not considered to be harmful for health, but they do affect the look and taste of the water, and may cause it to be undrinkable by some people. Addressing these water quality problems is therefore important and all have relatively simple solutions. A study was conducted in twenty villages of Lahore district to assess the physical and aesthetic quality of ground water. It was observed that in rural areas, ground water is used for domestic and drinking purpose. Therefore, tube wells water samples from twenty villages were collected. Bore depths ranged from 60 to 380 feet. Three water samples were collected from each of twenty villages and were analyzed for total dissolved solids, electrical conductivity (EC), taste, odour, colour and turbidity. Analysis showed that regarding color, odour, and taste all water samples were fit. Considering World Health Organization permissible limit for turbidity (5 Nephlometric Turbidity Unit) all the water samples were fit. Regarding total dissolved solids, 33.3% water samples were unfit while, 64.7% were fit considering the WHO criteria (1000 mg/l). Regarding pH, 75% of water samples were unfit for drinking and only 25% water samples fall within safe limit. Considering all the parameters, 10 samples (16.6%) were fit and remaining 50 samples were unfit out of total 60 water samples.
