Water, the Nectar of Life’, is fundamental resource which is essential for the survival of different sectors, such as agricultural sector, industrial sector and small business units. In the absence of proper planning, urbanization and industrial/agricultural activities have adversely affected many regions around the world. This has led to indiscriminate actions, including dumping of wastes into the water and washing and bathing in open surface water bodies. In the present study groundwater samples from five sampling locations were collected and the analyses were done for nine physicochemical parameters.Water quality index assessment was carried out by using physicochemical analysis results. Water quality index of the sampling locations of Allahabad city has been divided into five categories. Good water quality index has been put into location 1 while locations 2, 3 and 4 indicate bad quality index. Very bad water quality index has been denoted in location 5. Correlation, the descriptive relationship among the physicochemical parameters, were also studied and it was found that the highly positively correlated values were among the parameters TDS vs EC (r=1.00), TS vs TSS (r=0.91), Temp vs TSS (r=0.87), Phosphate vs TSS (r=0.823) and highly negatively correlation was shown among TA vs Chloride.The result shows that the water quality of Allahabad city is not good and there is an urgent need for the preliminary treatment of water before it is used for the drinking purposes. There is also the need for the proper waste disposal and treatment system for the contaminants which seep in the groundwater and deteriorate groundwater quality. Awareness programmes should also be organized to educate the masses for the conservation and management of groundwater resources and the need to reduce of overuse and wastage of the groundwater resources should be emphasized. Sustainable water development in the city is needed to fulfill the demand of water for future.

Large sets of water quality data can leave water quality managers and decision-makers totally overwhelmed. In order to convey the interpretation of the data in a simplified and understandable manner, the water quality results from bi-monthly surveys undertaken at seven different sampling sites in the Letaba, Olifants, and Selati rivers over a two year period (February 1990 to April 1992) were reduced to index values, using a water quality index. The water quality index (Aquatic Toxicity Index or ATI) revealed spatial and temporal trends. The higher index values, recorded for the sampling sites towards the eastern part of the Kruger National Park (KNP), revealed that the water quality was better than the quality measured in the Olifants River on the western bound-ary. The lowest index values were calculated for the Selati River, with index values consistently below 50. Index values indicate that the water quality in the Selati River was unsuitable for supporting normal physiological processes in fish. The water quality of the Selati River had an immediate impact on the water quality of the Olifants River directly below the confluence. Lower index values recorded at sites further downstream was also attributed to the influence of the Selati River since there are no known point sources of contaminants within the boundaries of the KNP. The index scores also elucidated temporal trends with lower scores evident during winter months. This was due to reduced flow in the Olifants River and a greater contribution of contaminated water from the Selati River. Index values increased following the first seasonal rains due to a dilution effect. Very low index values were recorded at certain sites during flood periods due to increased turbidity, reduced oxygen, and increased metal concentrations.

Quality Indexes

Water quality indexes are a tool used to evaluate the physicochemical characteristics of a water body according to its use. The present study proposes the inclusion of oil and grease (OG) as a new water quality index (ICAMPFF-GA) parameter for the preservation of marine biota in tropical areas, since it is a typical pollutant found and measured in water bodies, causing damage to the aquatic environment. The normalized curve for OG was defined based on the percentage of surviving microorganism under a lethal concentration exposure of OG. The ICAMPFF-GA suitability was evaluated by its application to analyze marine water quality in the area of the sea outfall in the city of Cartagena, Colombia and comparing the trends of the outfall flow and the rainfall for 2017. Physical chemical data analyzed for the year 2017 shows that OG varies from 0.0 to 3.8 mg/L. The results show that the water quality index increases when rainfall and flow values increase for the rainy season. The ICAMPFF-GA can be a tool to evaluate the water quality of marine waters affected by the discharge of waters with oil and grease.

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.
