The City

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.

Diyala River

Diyala River is a tributary of Tigris River, it is one of the important rivers in Iraq. It covers a total distance of 445 km (275 miles). 32600 km2 is the area that drains by Diyala River between Iraqi-Iranian borders. This research aims to evaluate the water quality index WQI of Diyala River, where three stations were chosen along the river. These stations are D12 at Jalawlaa City at the beginning of Diyala River, the second station is D15 at Baaquba City at the mid distance of the river, and the third station is D17 which is the last station before the confluence of Diyala River with Tigris River at Baghdad city. Bhargava method was used in order to evaluate the water quality index for both irrigation and drinking uses. The results indicated that Diyala river water quality at its beginning was excellent for irrigation and good for drinking, while at the mid distance of the river, it was good for irrigation but heavily polluted and unsafe for drinking. Water quality of the river at the third site was acceptable for irrigation but again severely polluted and unsafe for drinking.

Aim of the study: In the present study, the spatial – temporal variations of water quality in Boyalı Pond were analyzed. Water Quality Index (WQI) based on the World Health Organization's standards specified for drinking water, and Water Quality Control Regulations in Turkey (WQCR), as well as certain multi-statistical methods, were used in analyzing the water quality. Material and methods: Water samples were collected from 5 stations selected in the lake on monthly basis in 2019 and 30 water quality parameters were measured in total. Water Quality Index (WQI), Factor Analysis (FA), and Cluster Analysis (CA) were used in order to determine the differences between the spatial and temporal quality levels and to classify the investigated locations. Results and conclusions: According to data observed, Boyalı Dam Lake was found to have Class I and Class II water quality in general the WQI results obtained suggested that, although the water quality was found to significantly decrease in summer months, the reservoir was found to have an "A Grade – Excellent" water quality (<50) in all the months and stations analyzed here. WQI values recorded in the dam lake ranged between 16.4 and 27.8 and the detected limnologic parameters did not exceed the standards specified for drinking water in any of the investigated months and stations (<50 for WQI). As a result of FA, 3 factors explained 88.9% of total variances and as a result of CA, 2 statistical clusters were formed.

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.
