In the present study, both the underground and surface water samples around Guru Nanak Dev Thermal Power Plant Bathinda, Punjab, having total installed capacity of 440MW, were analyzed for the physico-chemical parameters viz. pH, Electrical Conductivity (EC), Total Dissolved Solid (TDS), Total Hardness (TH), Calcium (Ca2+), Magnesium (Mg2+), Total Alkalinity (TA), Carbonate (CO32-), Bicarbonate (HCO3-), Chloride (Cl-), Phosphate (PO43-), Nitrate (NO3-), Fluoride (F-) and heavy metals such as Cadmium (Cd), Copper (Cu), Lead(Pb), Nickel (Ni) and Zinc (Zn). The correlation coefficients (r) among various water quality parameters of studied underground water samples were calculated. The physical and chemical parameters of groundwater are compared with the drinking water quality standards recommended by Bureau of Indian Standards (BIS) (2012) and World Health Organization (WHO) (2017). On the basis of results obtained in the present study, concentration of Chloride (Cl-), Magnesium (Mg2+), Fluoride (F-) and Total  dissolved solids (TDS) observed in ground water of Bathinda varied from 30 to 284 mg/l, 120 to 280 mg/l, 2.66-3.99 mg/l and 620-1439 mg/l, respectively which are exceeding the acceptable limits prescribed by WHO (2017) as well as BIS (2012). Also, the concentration of heavy metals viz. cadmium (0.366 to 0.437 mg/l), and lead (0.193 to 0.353 mg/l) have higher levels than prescribed by WHO and BIS for drinking purpose. Thus, groundwater is not suitable for drinking purposes with prior treatment.

This study was conducted to assess the water quality of the lower Indus Basin, Pakistan. Eighty- two water samples were collected from forty-one locations of lower Indus Basin (Kashmore to Keti-Bander) during pre and post monsoon seasons. The variation pattern in the water quality has been observed in both seasons. The samples were analysed for physical quality (temperature, pH, turbidity, dissolved oxygen, total dissolved solids, salinity and conductivity), chemical quality (chloride, total alkalinity, total hardness, sulphate, potassium, sodium, iron, zinc, lead, mercury, copper, cadmium and nitrate) and biological quality (coliform bacteria). The study reveals that the concentrations of lead, mercury, and cadmium in water samples during both seasons were slightly higher than the permissible limits, whereas, all other parameters were within WHO guidelines. The higher concentration of heavy metals must be rectified by the concerned authorities in order to protect human health.

Poor Water Quality

Studying groundwater quality in arid and semi-arid regions is essential significant because it is used as a foremost alternative source for various purposes (human and animal consumption, economic, agriculture and irrigation). Geographic Information System and Water Quality Index techniques were utilized for visualizing and evaluating the variations of groundwater quality in the studied area. Total twelve wells were sampled and twelve groundwater quality (chemical) parameters; pH, Total Alkalinity, Total Hardness (TH), Total Dissolved Solid (TDS), Electrical Conductivity (Ec), Potassium (K), Nitrate (NO3), Sulfate (SO4), Chloride (Cl), Calcium (Ca), Magnesium (Mg) and Sodium (Na) were analyzed in the laboratory. Inverse Distance Weighted technique was used as a useful tool to create and anticipate spatial variation maps of the chemical parameters. Predicting or anticipating other areas not measured, identifying them and making use of them in the future without examining samples. The results of this research showed that 8.3% of the studied wells have excellent groundwater quality, and almost sampling wells about 75% found in good groundwater quality, while findings of groundwater quality of 16.7% studied wells belong to poor water quality due to standards of Water Quality Index. Moreover, spatial analysis in term of groundwater quality map showed that Excellent groundwater quality was detected in well 3, very good groundwater potential was noticed in six studied wells (wells 2, 6, 8, 10, 11 and 12), and other sampling wells (wells 4 and 7) were observed as good groundwater quality, while poor water quality was observed in wells (well 1 and 5). Hence, spatial distribution maps showed that the almost groundwater quality in the area about 1046.82 km² (99.04%) are suitable for drinking purpose, whereas proximate 10.18 km² (0.96%) are observed as poor water quality and inappropriate for consumptions especially in the southern part of the area.

Water Quality Indices

The present study was conducted to evaluate the quality of drinking water in randomly selected schools in Erbil city, Kurdistan Region, Iraq. The water quality indices such as the Heavy metal Pollution Index (HPI) and Heavy metal Evaluation Index (HEI) were applied to characterize water quality. Eighteen schools were incorporated and sampled for their water storage tanks available to students. Water samples and sediment samples from tanks floor were analyzed by Inductively Coupled Plasma Optical Emission Spectrometer for the determination of twenty-two metal elements. In drinking water samples, all detected metals did not exceed the permissible limits of the World Health Organization. The results of this study showed that the average values of HPI and HEI for As, Cd, Cr, Cu, Fe, Pb, Mn, Ni, and Zn were 54.442 and 0.221, respectively. According to data of the water quality indices, the schools drinking water quality are good and suitable for drinking in terms of heavy metals. However, sediments samples contained high concentrations of all elements including the toxic heavy metals (As, Cd, Cr, and Pb). Re-suspension of sediments into water column after refilling storage tanks can pose a serious threat to students drinking water from such vessels. It is therefore recommended that proper storage tanks are provided to the schools accompanied by continuous sanitation and hygiene practice to mitigate the corrosion of tanks to avoid health risks of toxic metal

Malwa region of Punjab state, India has become the center of water borne diseases due to excessive use of pesticides, chemical fertilizers, heavy metals, industrial toxins that cause toxicity in water. The main contamination in ground water is by physico-chemical parameters and heavy metals i.e. pH, total dissolved solids, total alkalinity, total hardness, calcium, chlorides, fluorides, arsenic and lead. The contamination of ground water with heavy metals causes health hazards to humans and animals. Due to lack of adequate facilities and resources for the management and handling of waste, the ground water contamination has been increased. In the present study, assessment of ground water quality was carried out in the villages of Ferozepur district of Punjab state, India. With main emphasis on analyzing the groundwater parameters of Ferozepur district which are responsible for health hazard to humans and animals. Various groundwater samples were collected randomly from the villages of Ferozepur district and analyzed for pH, total dissolved solids, total alkalinity, total hardness, calcium, chlorides, fluorides, heavy metals (arsenic and lead) using standard procedures. The concentrations of calcium, chlorides, fluorides and pH were within the permissible limits, whereas, alkalinity and total hardness were observed beyond permissible limits in most of the water samples. Even among majority of the samples taken, the concentration of arsenic and lead was found within the permissible limits. Results showed that the ground water samples collected from depth ranging from 100 to 360 ft, recorded values within permissible limits for drinking purpose as prescribed by WHO. Further, ANOVA has been applied on analysis results to study the effect of pH on fluoride and chloride, depth on fluoride and chloride and depth on arsenic and lead. Also, to adjudge the overall quality of water in Ferozepur district, the water quality index (WQI) has been calculated on the basis of large number of physico-chemical characteristics of water. The water quality index of ground water in Ferozepur district has been calculated to be 107. The value is close to 100 so the quality of ground water in Ferozepur district can be categorized under 'Good Quality' water.
