Abstract The quality of well-dug water for drinking and irrigation purposes must be measured as part of a sustainable groundwater analysis. The study aimed to assess water quality and to evaluate their usefulness for drinking and irrigation, using the Drinking Water Quality Index (DWQI) and Irrigation Water Quality Index (IWQI). To achieve this, standard methods were used for the determination of physicochemical parameters of the water samples, while using models (ESP, SSP, SAR, MAR, KR, TDS, and EC) to ascertain their suitability for drinking and irrigation. According to the findings, the determined Physico-chemical parameters were compared to standard limits and found desirable because they were within the guidelines. Low pH (6.4-7), total dissolved solids (106–130 mg/L), total hardness (42–56 mg/L), calcium (3.5–8.3 mg/L), magnesium (1.13.6 mg/L), nitrate (4.6–16 mg/L), chloride (1.8–3.1), and sulphate (14–15. mg/L) in the well samples were found to be the key cause of the low DWQI and IWQI value at these sites. The results also depicted that all the water samples are of exceptional quality (excellent).

In this paper, a study on the development  of water quality index of ex-mining ponds was carried out for proper assessment  and utilization of the abundant ex-mining ponds in Malaysia. Heavy metals were analyzed using inductively coupled plasma mass spectrophotometer (ICPMS), and physico chemical parameters were analyzed in-situ. Chemometric analysis was successfully applied for the parameter selection process. The water quality index of existing Malaysian river did not accommodate the toxic metal pollutants that dominanted in ex-mining water. The acceptable index should therefore incorporate the metal pollutants in order to evaluate the quality status of ex-mining water for human consumption which is the major point of consideration. Two water quality indices were developed to assess the water quality status of ex-mining ponds with reference to Malaysia’s water quality standard (INWQS). The heavy metal index was comprised of contribution from Pb, As, and Cd as the selected metals, while the physico-chemical parameter index has BOD, pH, DO, and AN. Chemometric analysis revealed the dominance of the selected heavy metals in ex-mining water, and physico-chemical parameters were important in water quality monitoring. Heavy metal water quality index revealed that most ex-mining ponds in Klang Valley were classified to be very poor hence could not be used for human consumption. Due to domestic input in some of the lakes in Klang Valley, the physico-chemical water quality index was in very poor status as well.  In Melaka and Negeri Sembilan, ex-mining ponds and lakes were classified as excellent in both indices.

The present study aims to identify the ground water contamination problem in villages located in the close vicinity of Gajraula industrial area at Gajraula (U.P.), India. Ground water samples were collected from different villages at the depth of 40 and 120 feet from earth’s surface layer. Analytical techniques as described in the standard methods for examination of water and waste water were adopted for physico-chemical analysis of ground water samples and the results compared with the standards given by WHO and BIS guidelines for drinking water. Water quality index was calculated for quality standard of ground water for drinking purposes. The present investigation revealed that the water quality is moderately degraded due to high range of seven water quality parameters such as Temperature (18.33-32.36 0C), conductivity (925.45-1399.59 μmho/cm), TDS (610.80-923.73 mgL-1), Alkalinity (260.17- 339.83 mgL-1), Ca-Hardness (129.68-181.17 mgL-1), Mg-Hardness (94.07-113.50 mgLÉ1) and COD (13.99-25.62 mgL-1). The water quality index (WQI) also indicated the all the water quality rating comes under the standard marginal values (45-64) i.e. water quality is frequently threatened or impaired and conditions usually depart from natural or desirable levels.

Groundwater contamination is a major problem in the Gaza Strip. In this study we investigate the groundwater quality in the Dier al-Balah Governorate. Water samples were collected from 19 municipal wells in April 2009 and April 2014 and analyzed for physio-chemical parameters (pH, TDS, Ca2+, Mg2+, Na+, K+, Cl−, SO42–, HCO3− and NO3−). The aim of the research is to determine the groundwater quality and to produce groundwater quality maps using the water quality index (WQI) method and geostatistical analysis. The results show that all water samples are very saline due to the intrusion of Mediterranean seawater in the coastal aquifer. Differences in chemical composition between 2009 and 2014 indicate that about 1% more seawater was mixed with the groundwater in this period. The majority of the observed chemical parameters of all wells are well above the WHO water quality standards and all WQI values indicate that the water quality is problematic. The spatial variation of the WQI scores is modelled by a deterministic component expressing a linear dependence on the distance to the coastline and a stochastic residual described by an exponential variogram with a practical range of 3000 m. The mapping of the WQI scores and derived water quality classes is achieved through regression-kriging. The results indicate that the groundwater in a large area along the coastline is unsuitable for human consumption and comparison of the maps of 2009 and 2014 shows that this region further expanded by about 700 m inland in a period of 5 years. The results of this study are worrying, but they also contribute to a better understanding of the factors that determine the groundwater quality and can help authorities and stakeholders with sustainable development.

A study was carried out to analyze the ground water samples from fifty sites within the urban settlements of Khushab city, Pakistan in order to to understand the distribution of contaminants and its impact on public health in the studied area. All the water samples were analysed using physico-chemical parameters : pH, Electric Conductivity (EC), Total Dissolved Solids (TDS), Total Hardness (TH), Ca+ , Mg+, Cl- and NO3-by using standard analytical methods. Salinity hazard was evaluated by using EC values inferred from the water samples. Water samples were classified on the basis of TDS and TH.Arc GIS software was used to plot the spatial distribution of contamination, concluded from the observed physico-chemical parameters throughout the study area. A door to door survey was also conducted to get the feedback from 100 people living in the houses, working in offices and shops to know the issues of water quality along with the level of satisfaction for the present water quality.Results showed that pH value ranging between 6.8 and 8.7, EC between 260 and 10290 S/cm, TDS between 179 and 9410 mg/l, Ca+2 between 1.2 and 11.8 mg/l, Mg+2 between 0.3 and 39.4 mg/l, TH between 6.23 and 216.86 mg/l, Cl- between 0.3 and 344.7 and NO3 between 12 and 62 mg/l. Results showed certain sites indicating poor water quality through deviation from WHO standard values of certain physico-chemical parameters. This showed that ground water at particular sites within the study area was unfit for drinking purpose and its prolonged utilization could cause serious health issues. More than 62% people reported their dissatisfaction regarding water quality and 80% agreed that water quality has drastically declined. Results were also correlated with the data collected from the Tehsil Headquarter Hospital which demonstrated that residents of Khushab city were suffering from the water borne diseases like Hepatitis, Cholera, Gastro, and Kidney stone etc. Almost 40,000 patients from Khushab city and the surrounding villages who suffered from water borne diseases visited the Tehsil Headquarter Hospital in the year 2014. It has been concluded from the study that the ground water of the study area has declined and needs proper and urgent attention from the government and water must be processed through state of the art purification treatment plants, before supplying to people for drinking and domestic purposes.

The quality of surface water and groundwater has deteriorated as a result of increased industrialization, urbanization and agricultural practices during the last few decades. Contaminated groundwater can cause major health problems in humans, such as typhoid and other infections. Similar in the case of Rabigh Governorate, the groundwater is one of the main sources of water for domestic and agriculture purposes in its villages situated in western Saudi Arabia. Many factories have been established in Rabigh region in recent years and day to day input of numerous untreated/partially treated water resulting in major environmental problems, one of which is the low quality of groundwater causing serious environmental and health issues. The presented study discusses the ground water as the main available and usable source in extremely climatic condition of arid area of Saudi Arabia. The article proceeds with the brief introduction of ground water, its contamination sources and health hazards. For this, 13 water samples were from the randomly selected wells in Rabigh Governorate for quality examine. Water quality index analysis was conducted, which is a useful technique for fast assessment of the quality of any water resource. Various physical and chemical parameters of water quality index such as pH, temperature, conductivity, turbidity, total dissolved solids (TDS), total suspended solids (TSS), total solids (TS), dissolved oxygen (DO), arsenic and E. coli are measured and analyzed. The values of all groundwater samples are compared with the standard WHO permissible values. The water quality of the wells were classified into “good, poor, very poor and unsuitable for drinking” based on physico-chemical parameters. According to the observed study, water quality range (WQR) for 5 samples (38% of the samples) are of poor quality, 3 samples (23%) are recorded with a very poor quality and 5 samples (38%) are not suitable for drinking purpose due to presence of high conductivity and TDS values. After taking into consideration the presence of E. coli in 31% of the samples (n = 4), about 62% of the samples (n = 8) are not suitable for drinking purpose, only 23% (n = 3) samples are of poor quality and 15% (n = 2) are very poor quality. The findings reveal a decrease in water quality (unsuitable for drinking purpose) in 8 out of 13 collected samples. It is believed that waste and industrial activities have an impact on groundwater quality in the study area, however, a nationwide investigation should be conducted to validate this finding.


Water Quality Index (WQI) is a widely used technique in defining the quality of groundwater and finding whether it is advisable for human use. It is utmost necessary steps to understand the physical and chemical parameters defining the water quality for particular period and location using WQI calculation as it gives information in a single value. WQI has been calculated in twenty ground water samples collected from selected sampling stations at Madurai in the pre-monsoon, monsoon and post monsoon seasons. The water quality index values suggested that almost all the ground water samples were above 150, which indicated that they were unfit for drinking and one sample from Vilangudi had WQI less than 100 which indicated the water as poor category for drinking but could be used for irrigation purposes. The groundwater quality is also defined to be little better during post monsoon season in all the samples than during pre-monsoon and monsoon season.

This present hydrological study assessed the groundwater quality of Biratnagar Metropolitan by the application of Water Quality Index (WQI). It has been determined on the basis of analyzed groundwater samples for some important physicochemical parameters such as pH, turbidity, electrical conductivity (EC), dissolved oxygen (DO), free carbon-dioxide (FCO2), bicarbonate (HCO3), total hardness (TH), phosphate (PO4-P), nitrate-N (NO3-N), arsenic (As), and fluoride (Fl) collected from 110 representative tube wells during post-monsoon period of 2015. The status of fluoride was below detectable level (BDL) in all the analyzed groundwater samples. The WQI for these samples ranged from 84.54 to 403.14. The high value of WQI has been found mainly due to the higher values of turbidity, FCO2 and arsenic in the groundwater. The results of study have been used to recommend models for predicting water quality. The classification of water quality on the basis of WQI value have been found to be good water (18.18%), poor water (59.09%), very poor water (13.64%) and unsuitable for drinking (9.09%). The result of the study suggests that the groundwater of the area needs some degree of treatment before consumption, and it also needs to be protected from the threat of contamination. The groundwater is one of the major source of drinking water as well as for irrigation in study area.
