“…The results suggest that a Powai lake WQI obj would be a useful approach for assessment of impacts on the receiving run-off, and NH 4 +-N and NH 2 +-N seem to be better indicators for aquacultural impacts as opposed to the suggestion of Simoes et al, (2008), who noted that eutrophication could be the typical indicator.…”

“…The investigators did not detect a significant influence in the sites. Simoes et al, (2008) used U.S. National Sanitation Foundation WQI, the minimum operator concept, and the WQI min in the assessment of the effects of pond aquaculture effluents on stream ecosystem and suggested that the deterioration due to aquacultural activity can be easily inferred with WQI min on three parameters: dissolved oxygen, turbidity and total phosphorus. The question of which parameters should be considered and how they are selected in the calculation of WQI for specific assessments of the impacts of aquaculture effluents on lake water quality remains to be answered.…”

“…Indices are measure of changes in a representative group of individual data points of various physicochemical and biological parameters in a given sample. The advantage of indices is that it has the potential to inform the general public and decision makers about the status of the ecosystem (Nasirian 2007;Simoes et al 2008). The benefit of this approach is the provision to evaluate the success and failure of any management plan for improving the water quality (Rickwood and Carr 2009).…”

Development of a water quality index (WQI) for the Loktak Lake in India

et al. 2017

The present work was carried out to assess a water quality index (WQI) of the Loktak Lake, an important wetland which has been under pressure due to the increasing anthropogenic activities. Physicochemical parameters like temperature (Tem), potential hydrogen (pH), electrical conductivity (EC), turbidity (T), dissolved oxygen (DO), total hardness (TH), calcium (Ca), chloride (Cl), fluoride (F), sulphate (SO 2À 4 ), magnesium (Mg), phosphate (PO 3À 4 ), sodium (Na), potassium (K), nitrite (NO 2 ), nitrate (NO 3 ), total dissolved solids (TDS), total carbon (TC), biochemical oxygen demand (BOD), and chemical oxygen demand (COD) were analyzed using standard procedures. The values obtained were compared with the guidelines for drinking purpose suggested by the World Health Organization and Bureau of Indian Standard. The result shows the higher concentration of nitrite in all the location which is beyond the permissible limit. Eleven parameters were selected to derive the WQI for the estimation of water potential for five sampling sites. A relative weight was assigned to each parameter range from 1.46 to 4.09 based on its importance. The WQI values range from 64 to 77 indicating that the Loktak Lake water is not fit for drinking, including both human and animals, even though the people living inside the Lake are using it for drinking purposes. The implementation of WQI is necessary for proper management of the Loktak Lake and it will be a very helpful tool for the public and decision makers to evaluate the water quality of the Loktak Lake for sustainable management.

“…O maior problema com a elaboração do IQA é classificar a qualidade da água em excelente, bom, regular, ruim e pobre, considerando que a qualidade da água é um conceito que depende da sua aplicação, como para a irrigação, recreação, uso industrial, abastecimento públi-co de água, a manutenção da vida aquática, entre outras (SIMÕES et al, 2008). Dessa forma, torna-se necessário o desenvolvimento de indicadores específicos para retratar melhor as condições de cada atividade.…”

Este trabalho teve como objetivo avaliar a sustentabilidade ambiental do uso de esgoto doméstico tratado na piscicultura por meio do Índice de Sustentabilidade Ambiental para Reúso em Piscicultura (ISA RP), do Índice de Qualidade de Água para Reúso em Piscicultura (IQA RP) e do custo ambiental (entropia). Observou-se, por meio do custo ambiental, que a piscicultura convencional causou a deterioração da qualidade da água que foi utilizada. Constatou-se que o sistema de piscicultura utilizando esgoto tratado, sem usar aeração, não causou efeito deletério significante à qualidade da água de reúso (efluente da estação de tratamento de esgoto - ETE). O sistema de piscicultura usando esgoto tratado, com aeração, resultou na melhoria de sua qualidade, quando comparado com o efluente da estação de tratamento, significando que essa prática resultou em um polimento no líquido utilizado. Ambos os sistemas de reúso de águas mostraram-se ambientalmente sustentáveis, o que indica a potencialidade do uso de esgoto doméstico tratado como fonte de água e alimento natural para a piscicultura.
