Índice de Qualidade de Água (IQACCME) Aplicado à Avaliação de Aquíferos do Estado do Rio de Janeiro

Abstract

The quality of some aquifers of Rio de Janeiro State was evaluated by applying, in 168 samples, the Water Quality Index (WQI) developed by the Canadian Council of Ministers of the Environment (CCME) in 1997. The maximum allowable values for the parameters were mostly those established by Brazilian Environmental Council CONAMA Resolution 396/08 for human consumption. The index was calculated with two compositions: a) Na + , Fe, Al, SO 4 2-, Mn, NO 3and Cland b) these and other cations, anions, pH and thermotolerant coliforms. The results of the two compositions differ. In general, the waters of Southern Rio de Janeiro State have the best rates, around 70% of the samples within the classes qualified as excellent and good. The opposite occurred with the waters of the Northwest and Coastal North and Eastern Rio de Janeiro, where most of the samples were ranked between regular and very bad.

Assessment of Hydrogeochemistry and Gis-Based Evolution of Groundwater Quality and Salinity in the Shallow Aquifer of São José Do Norte, Southern Brazil

“…The GQISWI can be categorized from 0 to 100, subdivided into 4 types of water, as seen in Table 1. Groundwater Quality Index for human consumption (GWQIHC) Menezes (2009) developed the Groundwater Quality Index for human consumption (GWQIHC) to be applied according to the legislations values, as water quality standards. In this way, GWQIHC algorithm has no weighting methods since they are subjective and can mask the groundwater quality assessment.…”

“…Groundwater suitability for human drinking purposes can be analyzed by quality indices, such as the Groundwater Quality Index for human consumption (GWQIHC) (Menezes, 2009;Sabino et al, 2020). The GWQIHC algorithm indexes several physical-chemical and biological parameters and calculates the groundwater potability in a single number.…”

Identificação e análise qualiquantitativa das fontes surgentes de água no perímetro urbano do município de Caçapava do Sul/RS

“…As fontes surgentes não se enquadram nas normas destinadas às águas subterrâneas, visto já estarem em contato com o ambiente, mas cabe ressaltar que Menezes et al (2013) sugerem no monitoramento da qualidade de águas subterrâneas, a utilização de limites estabelecidos para a classe 1 da Resolução CONAMA nº 357/2005 de águas superficiais (CONAMA, 2005), posto que a Demanda Bioquímica de Oxigênio (DBO), Oxigênio Dissolvido (OD) e pH, não possuem valores de referência para consumo humano na legislação de água subterrânea. Com base nos resultados dessa pesquisa em comparação aos limites propostos na resolução CONAMA n° 357/2005 todas as fontes se encontrariam na classe 4, pois nenhuma atende aos limites estabelecidos na referida resolução para os parâmetros OD, Nitrogênio Total e Nitrato.…”

Viability of the Use of Minimum Water Quality Indices: A Comparison of Methods

“…For a more extensive analysis, the minimum indices were classified using the two bands (Table 1) and then compared to the two "standard indices", since Pesce & Wunderlin (2000) and Moscuzza et al (2007) do not present a specific classification for the proposed methods. In turn, Naveedullah et al (2016) used an identical band of the IGAM (Table 1), possibly because this is the basis of WQI-NSF, since this index is internationally known (Jerônimo & Souza, 2013) and the most widespread index (Menezes et al, 2013).…”
