Radioactivity of naturally occurring (226Ra, 232Th and 40K) and anthropogenic (137Cs) radioactive nuclides was measured in 29 potable ground and surface water samples of Punjab, Pakistan. The results showed average activity concentrations for 226Ra, 232Th, 40K and 137Cs as 1.09, 0.55, 16.17 and 0.40 Bql−1, respectively. 137Cs was detected in only a few samples. The obtained results showed that, in general, activity concentrations of radionuclides (232Th and 137Cs) in drinking water samples did not exceed WHO recommendations. 226Ra in the majority of samples exceeded WHO drinking water guidelines. The estimated committed effective dose due to intake of the water for three age-groups considered (<1 y, 2–7 y and ≥17 y) was below the ICRP permissible limit (0.1 mSvy−1) except for 226Ra and 40K.

The occurrence of trihalomethanes (THMs) was studied in the drinking water samples from urban water supply network of Karachi city that served more than 18 million people. Drinking water samples were collected from 58 locations in summer (May-August) and winter (November-February) seasons. The major constituent of THMs detected was chloroform in winter (92.34%) and summer (93.07%), while the other THMs determined at lower concentrations. Summer and winter concentrations of total THMs at places exceed the levels regulated by UEPA (80 μg l-1) and WHO (100 μg l-1). GIS linked temporal variability in two seasons showed significantly higher median concentration (2.5%-23.06%) of THMs compared to winter.
