Assessment of groundwater quality of two selected villages of Nawada district of Bihar using water quality index

Unplanned discarding of industrial effluent, sewage, domestic and industrial solid waste, unwise use of insecticides, herbicides, pesticides, and fertilizer in agriculture are the major causes of groundwater quality reduction. In the present paper groundwater quality of the two selected village of Rajauli subdivision of Nawada district of Bihar was assessed using water quality index (WQI). The samples were figured out for the parameters such as temperature, pH, electrical conductivity (EC), total dissolved solids (TDS), alkalinity, dissolved oxygen (DO), total hardness (TH), chloride, calcium (Ca), magnesium (Mg), biochemical oxygen demand (BOD), and fluoride. All the parameters were found below the standard limits of Bureau of Indian Standard (BIS, 2012) except total hardness (328.1mg/l to 346.6mg/l), calcium (105.3mg/l to 122.6mg/l), magnesium (46.1mg/l to 55.7mg/l) and fluoride (4.8 to 4.9mg/l). Fluoride was observed more than 3 times than the standard permissible limit (1.5mg/l). Water quality index (WQI) was also applied on the obtained data to make it easy to understand. Based on WQI (including the fluoride), all the four sites fall in unfit for drinking category (250.79, 258.78, 281.78, 247.30) and in poor to very poor category (80.23, 88.19, 88.59, 64.60) excluding the fluoride from WQI calculation. Both the values of WQI shows that fluoride alone is not responsible for the degraded quality of water but other high concentration of salts is also responsible.

Drinking Purpose

Abstract Valuation of water quality index (WQI) is one of the simplest, easily understandable, and efficacious techniques to evaluate the quality and suitability of water for drinking as well as other purposes. This research was aimed to investigate the drinking water quality of tube wells from different areas in Khulna City, Bangladesh, by developing the WQI. Water samples from 59 tube wells were collected from different locations during the pre-monsoon time. pH, electric conductivity (EC), dissolve oxygen (DO), total dissolved solid (TDS), chloride (Cl−), nitrate (NO3−), and total hardness of the collected water samples were analyzed for the calculation of WQI. The mean value for pH, EC, DO, TDS, Cl−1, NO3−, and total hardness was 7.30, 1650 μS/cm, 1.60 mg/l, 1188.7 mg/l, 414.6 mg/l, 0.029 mg/l, and 52.03 mg/l, respectively. The calculated WQI values for individual places were distributed spatially through mapping by using ArcGIS software. Based on the WQI values, the drinking water was categorized into excellent, good, poor, very poor, and unfit for drinking purposes. The calculated WQI values ranged from 40.11 to 454.37 with an average value of 108.94. Among all the groundwater samples, 11.86% were excellent, 54.24% were good, 23.73% were poor, 1.69% were very poor, and 8.47% were unfit for drinking purpose based on WQI. The results showed that the groundwater quality of most of the studied areas of Khulna city could be considered safe and suitable for drinking barring the elevated EC and chloride content in some areas. Since Khulna city is situated in the southwestern part of Bangladesh and gradually approaches toward the base level of the Bay of Bengal which might be the source of salt concentration in the groundwater of Khulna city, Bangladesh.

Quality Of Water

AbstractGroundwater is an important source for drinking water supply in hard rock terrain of Bundelkhand massif particularly in District Mahoba, Uttar Pradesh, India. An attempt has been made in this work to understand the suitability of groundwater for human consumption. The parameters like pH, electrical conductivity, total dissolved solids, alkalinity, total hardness, calcium, magnesium, sodium, potassium, bicarbonate, sulfate, chloride, fluoride, nitrate, copper, manganese, silver, zinc, iron and nickel were analysed to estimate the groundwater quality. The water quality index (WQI) has been applied to categorize the water quality viz: excellent, good, poor, etc. which is quite useful to infer the quality of water to the people and policy makers in the concerned area. The WQI in the study area ranges from 4.75 to 115.93. The overall WQI in the study area indicates that the groundwater is safe and potable except few localized pockets in Charkhari and Jaitpur Blocks. The Hill-Piper Trilinear diagram reveals that the groundwater of the study area falls under Na+-Cl−, mixed Ca2+-Mg2+-Cl− and Ca2+-$${\text{HCO}}_{3}^{ - }$$ HCO 3 - types. The granite-gneiss contains orthoclase feldspar and biotite minerals which after weathering yields bicarbonate and chloride rich groundwater. The correlation matrix has been created and analysed to observe their significant impetus on the assessment of groundwater quality. The current study suggests that the groundwater of the area under deteriorated water quality needs treatment before consumption and also to be protected from the perils of geogenic/anthropogenic contamination.

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.

Thermotolerant Coliforms

In Brazil, about 49% of the population does not have access to the sewage collection network, with the consequent direct discharge of their sewage network into water bodies. Due to this scenario, it is essential to investigate the quality of the water consumed by thousands of people along the Negro and Resende Rivers. The present study analysis the waters of the Negro and Resende rivers, located in Dois Rios River Basin, in the municipality of Duas Barras, Rio de Janeiro State (RJ, SE Brazil), based on the Water Quality Index proposed by the National Sanitation Foundation (United States). The population of the district located in the municipality of Duas Barras dumps the domestic sewage directly into the hydrographic network. The analyzed parameters were: turbidity, total solid residue, total phosphorus, total nitrogen, biochemical oxygen demand (BOD), hydrogenation potential, temperature, dissolved oxygen and thermotolerant coliforms. The values obtained from the calculation of the Water Quality Index (WQI) showed a variation from 40 to 68, meaning that the quality of water vary between bad and acceptable in the study area. The samples collected in the urban area contained values for thermotolerant coliforms in disagreement with the maximum value permissible for classes 2 and 3 of fresh water by CONAMA (Conselho Nacional do Meio Ambiente; a Brazilian Council for the Environment) Resolution 357/2005. The results of the analyzes confirmed the contamination of the two rivers by the discharge of domestic effluents, showing that actions are necessary to eliminate or minimize the discharge of sewage in the surveyed water bodies, since it may cause public health risks. ResumoNo Brasil, cerca de 49% da população não possui acesso à rede de coleta de esgoto, com o consequente despejo direto da sua rede de esgotos em corpos hídricos. Diante deste cenário, torna-se indispensável investigar a qualidade da água consumida por milhares de pessoas ao longo dos rios Negro e Resende. A presente pesquisa analisou qualitativamente as águas dos rios Negro e Resende, localizados na Bacia Hidrográfica do Rio Dois Rios, no município de Duas Barras/RJ, a partir do índice de qualidade das águas proposto pela National Sanitation Foundation. A população do distrito sede do município de Duas Barras despeja o esgoto doméstico diretamente na referida rede hidrográfica. Os parâmetros analisados foram: turbidez, resíduo sólido total, fósforo total, nitrogênio total, demanda bioquímica de oxigênio, potencial hidrogêniônico, temperatura, oxigênio dissolvido e coliformes termotolerantes. Os valores obtidos no cálculo do índice de qualidade das águas (IQA) mostraram uma variação de 40 a 68, significando uma qualidade da água entre ruim e razoável. As amostras coletadas na área urbana apresentaram valores para coliformes termotolerantes em desacordo com o valor máximo permitido para classes 2 e 3 de água doce, regulamentados pela Resolução CONAMA 357/2005. O resultado das análises confirmou a contaminação dos dois rios pelo lançamento de efluentes domésticos, os quais poderão originar riscos de saúde pública. Os resultado evidenciam a necessidade de se desenvolverem ações para eliminar ou minimizar os despejos de esgotos nos referidos corpos hídricos.
