High Disease Burden

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.

This study deals with the statistical analysis and study of water quality index to assess hardness of groundwater in Todaraisingh tehsil of Tonk district of Rajasthan state. The study has been carried out to examine its suitability for drinking, irrigation and industrial purpose. The presence of problematic salts contains in groundwater due to local pollutants and affected the groundwater quality adversely. The estimated values were compared with drinking water quality standards prescribed by B.I.S. It was found that drinking water is severely polluted with hardness causing salts. This study reveals that people dependent on water sources of the study area are prone to health hazards of contaminated water and quality managements to hardness urgently needed.

The low level of water in rivers in Iraq leads to poor water quality, on that basis; we need to assess Iraq's water resources for uses of irrigation and drinking water. This study present a model accounts for ground water quality by using a water quality index (WQI) for the region defined between the city of Kut and the city of Badra in Wasit province. this study relies on a system of wells set up along the path through the Badra –Kut  and around it  up to 78 wells. The study showed poor quality of ground water in the region of study and it is unsuitability for irrigation and drinking water, as well as provided a solution to the water accumulated in the Shuwayja to reduce the bad effect on groundwater by using a system of branch and collection canals  then pumping at the effluent  of Al  Shuwayja in seasons of rainy season ..Water quality index calculated depend on the basis of various physic-chemical parameters as PH, Ec , TDS, TSS, Nacl , SO4 ,Na , and  Mg. The resultant and analytical are present with use of Arch GIS program – geostastical analysis for the water index and water quality parameters

Drinking Water Samples

One hundred and eighty drinking water samples were collected from five zones of Riyadh governorate including Riyadh main zone, Ulia, Nassim, Shifa, and Badiah zones. The water was collected from the main water network and underground and upper household tanks in each zone. The water quality was found to be acceptable for drinking with respect to chemical characteristics; however, analyses exhibited some microbial contamination. The water quality index (WQI) is a mathematical method used to facilitate water quality explanation. The WQI was calculated using several physico-chemical and microbial parameters. The results showed that more than 88% of Riyadh main zone, 91% of Ulia, 97% of Nassim, 88% of Shifa, and 100% of Badiah waters zones were considered excellent for drinking (class I). The remaining waters were considered unsuitable for drinking (class V) due to microbial contamination.
