“…30 The values detected were well below the BIS permissible limits of 0.05 mg l -1 . Zinc: The highest concentration of lead at Nalagarh region may be ascribed to large number of alloys and steel galvanizing industries and tannery plants in the region, as also has been reported in other studies in Banglasesh (Hasan et al, 2017). 31 Excessive use of insecticides in farming practices in this region may also be leading to higher concentrations of zinc in water sources.…”

Today, the quality of drinking water across the globe has become an environmental concern because of its degradation due to urbanization, industrialization, transportation etc. Solan, a rapidly developing district and an industrial hub, in the recent past has faced water borne diarrhoeal disease outbreaks. Therefore, the study was undertaken to assess the water quality of disease burden regions during monsoon and post monsoon seasons. pH of the water sources was in the range of 6.92- 7.43 and was well within normal limits. Electrical conductivity of water ranged from 151.40- 414.65 µS/cm. The water sources of high disease burden regions exhibited higher EC than the prescribed ICMR standards. DO (range 7.43- 8.56 mg/l) was normal in all disease burden regions. BOD (range 12.25- 23.25 mg/l) was higher than the BIS limits in all regions. The COD, TDS and turbidity (range 75.75- 157.50 mg/l, 2.24- 81.01 mg/l and 1.85- 5.05 NTU respectively) were within BIS limits. The concentrations (mg/l) of Ca, Pb, Hg, Zn and Cr was found in the ranges of 37.2- 122.9, 0.17- 0.51, 0.00- 0.03, 0.74- 8.99 and 0.04- 0.10, respectively. The high disease burden regions exhibited relatively higher contents of Ca, Hg and Cr as compared to lower one and the BIS limits. However, contents of Pb and Zn were above BIS limits in all the regions. The concentration (mg/l) of Mg, NO3-, Cl- and As was in the ranges of 14.25- 30.61, 5.10- 9.88, 16.42- 74.96 , 0.001- 0.014 respectively, which were below prescribed standards. Cd was detected (0.001 mg/l) in Solan region only, however it was within BIS limits. Water Quality Index (WQI) computed by using nine parameters varied from 78.58- 219.78 (very poor to unsafe drinking water class). Interestingly, water sources of all the high disease burden regions were unsafe for drinking (WQI: 102.02- 167.04). Water quality deteriorated more in the monsoons. The study therefore warrants remedial actions of water resource protection and conservation for provision of potable water.

“…Lead contamination in drinking water is considered unsafe category because it is higher than the standard limit and it is necessary to make community aware about the water quality before drinking. Therefore, the government could play a vital role by offering free testing service to ensure good quality water and risk management for drinking as well as preventing public health problems among community (Hasan, 2017).…”

The environmental conditions of Code River were strongly influenced by anthropogenic activities that include industry, hospitals, domestic, and agriculture. The contamination status on the Code River according to BLH Yogyakarta reported in 2014 was heavily polluted based on STORET (≤-31). The riverside community were misusing the river for final disposal site, potentially contaminating it with lead (Pb). Local communities were potentially exposed to Pb toxicity through well water consumption. An Environmental Health Risk Assessment (EHRA) study of ingestion exposure of heavy metals was never conducted in the Code Riverside, making it interesting for further studies. The study aimed to determine human health risks of consumption of well water containing Pb in Code Riverside, Yogyakarta City using an observational design with an Environmental Health Risk Assessment approach. There were 9 environmental samples and 47 respondents selected based on certain criteria. Data was collected through environmental inspection and human health assessment, interviews and anthropometric data measurement of respondents. Data was analyzed by univariate (frequency distribution) and EHRA methods. The result showed that the noncarcinogenic risk level of Pb due to well water consumption from majority of research sites have RQ value (Risk Quotient) > 1, which means high potential risk to human health.

“…Although all zinc concentrations from all the locations were below the WHO maximum permissible limit of 5.0 mg/L (WHO, 2006), and both the minimum and maximum values were measured during spring season, but a high value of 1.0 mg/L in Aleye Qr. might be due to the older galvanized metals pipes of that quarter and well cribbing might be coated with zinc that may dissolved by an acidic water, resulted in leaching of zinc to the water (Swaminathan et al, 2011 andHasan et al, 2017). The results from the statistical analysis exhibited no significant (P>0.05) difference among the four seasons for all the studied locations.…”

Drinking water considers one of the main concerns in most developing countries. The current study aimed to evaluate the quality of drinking water in Akre district, Kurdistan Region – Iraq in four different seasons, and to compare them with WHO standards. Drinking water samples were collected from seven densely populated quarters of the city. The samples were analyzed for their physico-chemical and heavy metal quality. Physico-chemical parameters were temperature, turbidity, Electrical conductivity “EC”, pH, Total Dissolved Solids “TDS”, Chlorine “Cl- ”, Sulphate “SO4-2”, Nitrate “NO3”, Sodium “Na+”, Zinc “Zn”, Copper “Cu”, total alkalinity, total hardness, Cadmium “Cd” and Plumbum “Pb”. These are indications of polluted water and weak treatment practice, which in turn will cause many human health problems. The results from this study showed that almost all the water samples were normal in compare to the WHO guidelines, except for the total alkalinity, total hardness, Cd and Pb, were showed to be higher than WHO standards in some locations. Therefore, the study recommends the city authorities to improve their drinking water treatment or use alternative water supply to have a better drinking water.
