Increasing Demand

Increasing demand for water from agriculture, industrial and domestic sectors, resulted in stress on the water resources both from quantity and quality perspectives. Due to urbanization many of the dyeing units have shifted from urban to nearby rural areas. Here safe disposal of untreated effluent from the dyeing units is a challenge and is often let into nearby water bodies. Pandravedu Lake, located in Thiruvallur district of Tamil Nadu, India is one such case were the present study is carried out. Water samples were collected from twelve locations during pre-monsoon, monsoon and post-monsoon seasons, in pre-cleaned polyethylene cans and analyzed for physico-chemical parameters like pH, total dissolved solids, electrical conductivity, total alkalinity, total hardness, calcium, magnesium, sodium, potassium, iron, nitrate, chloride, fluoride and sulphate following the standard analytical procedures recommended by American Public Health Association (2005).The analytical results indicated that 40% to 70% of samples exceeded the drinking water quality standards prescribed by Bureau of Indian standards (BIS, 2012). Water quality index computed indicate that both the bore wells that supply drinking water to the village falls in very poor category (101 – 150) across three seasons. Correlation analysis indicated that seasonal changes in correlation among the parameters are linked to the fluctuations of wastewater discharge and its characteristics.

Purpose. The hygienic aspect of drinking water safety and quality can be defined by the indices of epidemic safety, sanitary, chemical and radiation indices, as well as the optimal content of mineral substances, i.e. a mineral composition adequate to the physiological need of a human body: total hardness, total alkalinity, the content of iodine, potassium, calcium, magnesium, sodium, fluorine and solid residual (mineralization) Assessment of drinking water mineralization as indicator of water quality. Possible impact of mineralization level to the health of population in urbanized territories of Ukraine. Methods. Assessment of drinking water mineralization level is based on water supply organizations providing the investigations in the different urbanized territories of Ukraine. Results. The estimation of drinking water mineralization from surface and underground sources for water supply of local urbanized territories of Ukraine had been done. Also the analysis of water quality indicator in this content and possible influence on human health had been presented. Conclusions. Fluctuations of mineralization and indicators of the physiological usefulness of the mineral composition compared with the range of optimum had been marked as a distinguishing. After clearing underground waters in pumped-out complexes, their mineralization is usually reduced to an optimal value, but also significantly reduces the concentration of calcium, magnesium and other essential elements. Numerous literary indications indicate a connection between the level of mineralization (composition) of drinking water and the state of health of the population. There is a correlation between the level of mineralization (balance of mineral composition) of drinking water and human health. Long-term consumption of drinking water with an imbalance of essential mineral components can be one of the negative impacts on public health.

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.

Physico chemical parameters such as colour, odour, taste, temperature, pH, electrical conductivity, TS, TDS, total hardness, total alkalinity, calcium, magnesium, iron, sodium, potassium, chloride, sulphate, nitrate, fluoride and silica were determined. In microbiological study, total coliforms, E. coli, sulfate reducing anaerobic bacteria, pseudomonas aeruginosa, yeast and mould were investigated. Samples were taken from ten sampling points in ten different villages viz. Parvat(S-1), Kharvasa(S-2), Bonand(S-3), Vesu(S-4) Amroli(S-5), Kadodara(S-6), Chalthan(S-7), Variyav(S-8), Gaviyar(S-9) and Bhairav(S-10). Samples were taken four times in year in the month of May, August, November and February to check the seasonal effects. In village Gaviyar, Gujarat Water Supply and Sewerage Board has set up a treatment plant to supply good quality potable water in few surrounding coastal villages. In all other cases samples were taken from bore-well. Here study reported is for samples taken in May-2004 and August-2004.For colour, iron, sulphate, nitrate, fluoride and silica, instrumental methods like spectrophotometry were used. “Hach-Odyssey spectrophotometer” which has facility to store calibration curves and which can display the value for that parameter directly was used. In present study programmes of “Hach” with their reagents were used while some programmes were prepared by us using our reagents. This is an excellent instrument and results of this instrument are validated by USEPA. Sodium and potassium was determined using flame photometer. It was found that some water samples have higher TDS, chlorides, total hardness and total alkalinity than the permissible limits. In all cases samples were not found to contain significant quantities of bacteria and water was palatable from this point of view.

Safe source of drinking water is always considered as an essential factor in water supply for cities and urban areas. As a part of this issue, drinking water quality is monitored via a useful scheme: developing drinking water quality index DWQI. DWQI is preferably used as it summarizes the whole physicochemical and bacteriological properties of a drinking water sample into a single and simple term. In this study, an evaluation was made for three drinking water treatment plants DWTPs named: Efraz 1, Efraz 2 and Efraz 3 that supply drinking water to Erbil City. The assessment was made by testing thirteen physicochemical and two bacteriological parameters during a long period of (2003 – 2017). It has been found that turbidity, electrical conductivity EC, total alkalinity, total hardness, total coliform and fecal coliform have more influence on drinking water quality. DWQI results showed that the quality of drinking water supplied by the three DWTPs in Erbil City fallen within good level. Except various occasional periods where the quality was varying from good to fair. The quality of the drinking water supply never reached the level of marginal or poor over the time investigated. The applied hierarchical clustering analysis HCA classifies the drinking water dataset into three major clusters, reflecting diverse sources of the physicochemical and bacteriological parameter: natural, agriculture and urban discharges.

This work assessed the groundwater hydrogeochemistry and the drinking water quality of 10 wells supplying the urban area of Zamora, Michoacán, Mexico. Two sampling campaigns were conducted in May 2018 (dry season) and November 2018 (wet season) to describe the chemistry of the water and its interaction with the rock. Physical and chemical constituents (temperature, pH, electrical conductivity, color, turbidity, solids, total hardness, total alkalinity, chemical and biochemical oxygen demands), major components (Ca2+, Mg2+, Na+, K+, SO42−, PO43−, HCO3−, CO32−, Cl−, N-NO3−, and N-NH3), as well as trace elements (As, Fe, Mn, Ba, Al, Sb, Co, V, Cu, Cd, Cr, Ni, Zn, Tl, Pb) were analyzed. Results showed groundwater with a slight tendency to alkalinity. The hydrogeochemical facies observed are Ca2+-HCO3− in all sites. Hydrochemical diagrams indicate immature, cold, non-saline, and uncontaminated water with short residence time. Water–rock interaction predominates. The water in the study area is appropriate for drinking use according to Mexican and international regulations with an excellent quality in 7 wells and good in the other 3.
