“…However, most WQIs have been developed for general water purposes, such as Horton's Index, the National Sanitation Foundation (NSF) Index, the British Columbia Water Quality Index, the Oregon Water Quality Index, the Overall Index of Pollution, the River Pollution Index (RPI), and the Universal Water Quality Index (Liou et al 2004). Only a few WQIs have been developed based on specific water-use purposes, such as the water supply or drinking water (Mohebbi et al 2013;Wanda et al 2012;Ramesh et al 2010), recreation or water sports (Smith and Daviescolley 1992;Anderson et al 2012;Kamizoulis and Saliba 2004;Marino et al 1995;Nagels et al 2001), public bathing (Smith et al 1991;Kamizoulis and Saliba 2004;Kay 1988), estuaries or coastal water systems (Garcia-Marin et al 2013;Neto et al 2013), irrigation or agriculture (Goss and Richards 2008;Herricks and Suen 2006;Al-Bassam and Ai-Rumikhani 2003;Wang et al 2011), livestock (Gharibi et al 2012), and marine shrimp culture (Ferreira et al 2011). Many government agencies have applied WQI to develop their own standards for various water purposes, which differ with regard to the specific terms used for the classification schemes and in the selection of indicator parameters (Bordalo et al 2006;Sarkar and Abbasi 2006;Suen and Herricks 2009;Bordalo et al 2001).…”

Due to a lack of the related data, there were no simple water indexes available for indicating water quality. Motivated by the fact that many lakes and reservoirs in Indonesia have been polluted because of aquacultural activity, this paper proposed a Water Quality Index, called the Aquaculture Water Quality Index (AWQI), and presented the development of practical tool to aid the development of aquaculture in Indonesia. Specific purposes included: (a) providing a brief summary of the assessment results of the existing WQI; (b) developing the AWQI method for applying in an aquacultural context; (c) implementing the AWQI method in Depok Area (Indonesia) as study area. An AHP method was also processed to define the weights of selected water quality parameters: DO, ammonia, pH, and fecal coliform. The AWQI had several features: (a) a low-cost water quality monitoring program that could be used by developing countries; (b) a useful tool for water resource agencies, especially for local agencies, to manage waterbodies and to raise public awareness of water pollution for its data, as its data could be easily understood and interpreted.

“…Although fuzzy sets and fuzzy optimization could provide a useful technique to address the imprecision in the objectives and water quality standards, the subjective factor plays an important role in the choice of classes and fuzzy memberships of the indicators. Several pollution indices have also been developed to evaluate groundwater quality, including the DRASTIC groundwater vulnerability index [14], the WQI index [15], the modified DWQI index [16], the GWQI index [17], and the limit-risk index [18]. Compared with the above-described methods, the pollution-index method is relatively easy to implement and requires a small amount of data.…”

Chongming Island is located in the lower Yangtze Estuary in China. Due to the Leachate from a refuse landfill and the hydrodynamics of the Yangtze Estuary, the groundwater environment is particularly complicated on Chongming Island. Field observations were carried out around the landfill disposal site. The groundwater table, temperature, pH, salinity, and dissolved oxygen were measured in the field by portable equipment, and 192 water samples were collected at eight groundwater sites and one surface water site. Through laboratory analysis we found the highest measured concentration of Cr to be 54.07 μg/L, and the measured concentration of Zn was in the range of 8 μg/L to more than 200 μg/L, which were both higher than their background values. Strong correlations were found between the heavy metal (Cr, Ni, Cu) concentrations and physico-chemical characteristics (salinity and pH), which indicated that both the landfill and the tides played an important role in the distribution of heavy metal concentrations. Both the HPI and PoS Indices were greater than their critical values near the disposal site, indicating groundwater pollution by heavy metals. We show that Cr and Ni are the major heavy metals causing groundwater contamination in the study region.

“…O IQA-CWQI permite que sejam incluídos outros atributos, tornando-o flexível, conforme foi constatado por Mohebbi et al (2013), que modificaram o modelo canadense e o chamaram de DWQI modificado, onde foram incluídos dois subíndices, um relacionado à saúde e outro à aceitação em termos estéticos, utilizado para avaliar a qualidade da água potável de manancial subterrâneo em áreas urbanas do Irã. Foram utilizados 21 parâmetros medidos em 5.314 pontos de amostragens durante um período de um ano, em que foi constatado que o modelo atribuiu melhores condições à água, diferenciando em apenas 13% das províncias e atingindo o objetivo para a avaliação da qualidade da água, afirmando que o modelo modificado pode ser utilizado em todo o mundo.…”

. RESUMOA avaliação da qualidade da água a ser consumida pela população é algo imprescindível. Para isso são utilizados parâmetros físico-químicos e bacteriológicos, os quais devem estar dentro dos limites estabelecidos em legislação. Dessa forma, este trabalho determinou e comparou a aplicação de dois Índice de Qualidade da Água (IQA) de 249 amostras de água tratada, coletadas no sistema de abastecimento de água da cidade de Goiânia num período de janeiro de 2012 a julho de 2013. As amostras foram submetidas à avaliação considerando 10 parâmetros físico-químicos e 3 microbiológicos e, em seguida, calculados os valores de IQA, com um Modelo Canadense e outro Modelo empregado pela Companhia Saneamento de Goiás S.A. -SANEAGO. Os resultados indicaram que a água distribuída em 88,8% das amostras foi classificada como de excelente qualidade pelos dois modelos, o que evidencia que o modelo empregado pela SANEAGO é mais restritivo que o Modelo Canadense, além do que existe uma influência sazonal que aponta para uma pior classificação das águas analisadas na época das chuvas. Palavras-chave: IQA, Qualidade da água, Modelo Canadense. ABSTRACTThe assessment of water quality destined to population consumption is something essential; for this reason the physical, chemical and bacteriological parameters are monitored and must be according to the limits established in legislation. Thus, the present study has determined and compared the application of two Water Quality Indexes (WQI) of 249 treated water samples, collected in the water supply system of the city of Goiania, during a period of 24 months. These samples were subjected to analysis of 10 physical-chemical parameters and 3 microbiological parameters. The WQI values for the samples were determined using a Canadian WQI calculation model, and also by using different calculation model, employed by the local State Company. The results indicated that the water distributed in 88.8% of the samples were rated as excellent by the two models, indicating that the model employed by local State Company is more restrictive than the Canadian model, besides that there is a seasonal influences pointing to a worse water classification in the rainy season.
