Bottled Mineral Water

The purpose of this test was to evaluate the physicochemical (ammoniacal nitrate, nitrogen nitrate, nitrogen nitrite, pH, orthophosphate and turbidity) and microbiological parameters (Escherichia coli and total coliforms) of mineral water samples bottled trademarks and compare the results obtained with Brasilian Ministery of Healty Ordinance 2.914/11. For this purpose, it was used trademarks mineral water bottled sold in pet 300 and 500 ml bottles. For microbiological analysis it was used Colipaper (Alfakit®), and all of them the analysis of physicochemical parameters was used Ecokit II (Alfakit®). From the five mineral water bottled samples, all were within the physicochemical parameters determined by Ordinance 2.914/11. In the microbiological findings, only one sample presented Escherichia coli. Therefore, all the analyzed brands meet the required physicochemical parameters of water quality for human consumption, except brand A, which did not meet the microbiological parameters. The results demonstrates the need for confirmatory tests performed by laboratories qualified to attest the result obtained, as well as the need to implement more effective monitoring by the responsible agency for monitoring the water quality for human consumption.

Nesse trabalho, foi analisada a qualidade da água em níveis bacteriológicos para consumo humano e demais usos em reservatórios denominados Tanques de Pedra nas comunidades rurais do Semiárido Paraibano: KM 21, Campina Grande (Agreste paraibano)-PB, e Pedra Redonda (Curimataú paraibano), Pocinhos-PB. Como critério de escolha das comunidades, considerou-se a importância dos reservatórios para a população, haja vista serem o principal reservatório para captação de água da chuva e armazenamento. A qualidade da água foi analisada a partir de sete coletas com a determinação dos parâmetros físico-químicos e microbiológicos. A metodologia aplicada foi o método enzimático de substrato definido Colilert. Para as análises físico-químicas, utilizou-se 24 parâmetros identificados pelo Valor Máximo Permissível (VMP). Os resultados, para parâmetros microbiológicos e físico-químicos, estão fundamentados na Portaria 2914/11 do Ministério da Saúde. Utilizou-se registro fotográfico para obtenção de imagens dos reservatórios. Os resultados mostraram que a qualidade da água das comunidades encontrava-se comprometida, tendo em vista que se encontrava infectada nos níveis bacteriológicos (Escherichia coli e Coliformes totais) e físico-químicos para cor e turbidez, sendo estes parâmetros utilizados para consumo humano. Assim, concluiu-se que, nos casos da utilização do recurso hídrico para usos múltiplos da água, pode haver utilização, porém com algumas restrições. Por fim, é válido destacar que os tanques de pedra são o maior provedor de água para as famílias de ambas as comunidades, por este motivo a análise da qualidade da água deu-se para este tipo de reservatório dado a sua importância aquífera e social.    A B S T R A C T In this study, the water quality was analyzed for bacteriological levels for human consumption and other uses in so-called reservoirs Stone Tanks in rural communities Paraibano Semi-Arid: KM 21, Campina Grande (Agreste Paraibano)-PB, and Pedra Redonda (Curimataú Paraibano), Pocinhos-PB. As a criterion of choice of the communities, it considered the importance of reservoirs for the population, given as the primary reservoir for capturing rainwater and storage. The water quality was analyzed from seven collections with the determination of physical, chemical and microbiological parameters. The methodology applied was the enzymatic method of substrate defined Colilert. For the physico-chemical analysis, we used 24 parameters identified by the Maximum Permissible Value (MPV). The results for microbiological and physico-chemical parameters are based on the Ministry of Health Ordinance 2914/11. We used photographic record to obtain images of the reservoirs. The results showed that the water quality of communities found compromised, considering that was infected in the bacteriological level (Escherichia coli and Coliforms totals) and physico-chemical for color and turbidity, these parameters being used for human consumption. Thus, it was concluded that in cases where the use of water resources for multiple uses water can be used, but with some restrictions. Finally, it is worth noting that the stone tanks are the largest water provider for the families of both communities, for this reason the analysis of water quality was given for this type of reservoir given its importance aquifer and social.

In the country, among the fundamental environmental problems is the contamination of surface waters of rivers, as in the case of the Pisco River. The objective of the research work was to determine the physicochemical and microbiological indicators, for their use in the irrigation of vegetable and animal beverages under the regulation of the D.S. 004-2017-MINAM, category 3 (Pisco river category). Four samples were collected at the four sampling points in the months of June-September of the year 2019, during the dry season, these samples were collected according to the methodology of the National Protocol for monitoring the quality of surface water resources. woolen. Parameters were measured in the field such as: T, pH, conductivity, total dissolved solids,% sodium chloride and turbidity, using a pH meter, multiparametric and turbidimeter. The concentration of the other physicochemical parameters and the microbiological parameters were determined in the UNSLG laboratories. The results were compared with D.S. 004-2017-MINAM. The parameters that were measured in the field comply with the ECA for surface waters of a category 3 river, while the physicochemical parameters such as: Al, Cu, Fe and Zn have higher values ​​than the ECAs in all the sampling points. The microbiological parameters (Thermotolerant Coliforms and Escherichia coli) did not comply with the RCTs at points RP1 and RP2.The presence of these contaminants makes the water unsuitable for the purposes studied, in the same way for human consumption.   En el país, entre los problemas ambientales fundamentales está la contaminación de las aguas superficiales de los ríos, como es el caso del río Pisco. El objetivo del trabajo de investigación fue determinar los indicadores fisicoquímicos y microbiológicos, para su uso en el riego de bebidas vegetales y animales bajo la norma del D.S. 004-2017-MINAM, categoría 3 (categoría río Pisco). Se tomaron cuatro muestras en los cuatro puntos de muestreo en los meses de junio-septiembre del año 2019, durante la época seca, estas muestras se tomaron de acuerdo a la metodología del Protocolo Nacional de monitoreo de la calidad de los recursos hídricos superficiales. lana. Se midieron en campo parámetros como: T, pH, conductividad, sólidos totales disueltos,% de cloruro de sodio y turbidez, utilizando un medidor de pH, multiparamétrico y turbidímetro. La concentración de los demás parámetros fisicoquímicos y los parámetros microbiológicos se determinaron en los laboratorios de la UNSLG. Los resultados se compararon con el D.S. 004-2017-MINAM. Los parámetros que se midieron en campo cumplen con el ECA para aguas superficiales de un río de categoría 3, mientras que los parámetros fisicoquímicos como: Al, Cu, Fe y Zn presentan valores superiores a los ECA en todos los puntos de muestreo. Los parámetros microbiológicos (Coliformes Termotolerantes y Escherichia coli) no cumplieron con los ECAs en los puntos RP1 y RP2.La presencia de estos contaminantes hace que el agua no sea apta para los fines estudiados, de igual manera para el consumo humano.

This work describes the approach of a situation of potential risk to health due to nitrate contamination in water intended for human consumption, found in a study conducted in 88 municipalities in the Northeast region of the State of São Paulo (Brazil). 4,347 public water supply samples were analysed for 21 physico-chemical and 2 microbiological parameters. A municipality was distinguished from the others with regard to higher nitrate levels, while the principal components analysis showed that it belonged to a group of 14 municipalities (nitrate group). The Sanitary Surveillance Group was then contacted and, after confirmatory tests in new public water supply samples, analyses were performed on water samples from 16 wells in the county. The groundwater contamination was found, and technical meetings were held. One of the deliberations was the repetition of water analyses of the 16 wells. Consolidated results showed that the 5 wells had nitrate levels above the maximum value permitted by legislation. To mitigate nitrate groundwater contamination of that municipality actions are being taken as a result of 3 technical meetings already held. The other municipalities of the nitrate group are being monitored.

The Tocantins River has abundant water resources and favorable conditions for recreational activities, with emphasis on the beautiful natural beaches formed along its length. However, it is worth noting that the main contact entertainment and leisure activities require specific health and safety standards for bathing purposes. This study evaluated the water quality of Praia Beira Rio, in Porto Nacional-Tocantins, in only one point. For this purpose, microbiological analysis was performed using indicators of total coliforms and Escherichia coli (E. coli) following the method described by APHA (2005). The monitoring results were compared with the parameters for bathing purposes defined in CONAMA Resolution 274/00. To detect and identify total coliforms and Escherichia coli, the Colilert technique was used. The Escherichia coli content was low, allowing bathing waters to be classified as their own, according to CONAMA Resolution No. 274/00, and subdivided into the "excellent" category. Therefore, according to the bacterial indicators of the Escherichia coli group, during the analysis period, the waters of Praia Beira Rio were within the standards for primary contact recreation.

The Impact

Abstract Faecal contamination of surface water sources is an important water quality issue worldwide. Although quite a few studies exist on surface water faecal contamination and variability of indicator bacteria, most of the studies have been based on larger river basins and in temperate region. The variability is relatively unknown in local scale and in tropical developing countries. In this study we assess how anthropogenic and environmental factors affect faecal contamination and physicochemical parameters in Rupsha and Bhairab rivers around Khulna city, Bangladesh. Water samples were collected from six locations of the rivers during a wet and dry period in 2018 to measure Escherichia coli (E. coli) concentrations. Water physicochemical parameters—temperature, turbidity, pH, dissolved oxygen, biochemical oxygen demand and chemical oxygen demand were also measured. Higher concentrations of E. coli were found in the sampling sites located near the densely populated urban area compared to the downstream site, which receives fewer amounts of discharges from sewer drains. All the E. coli samples violated bathing water quality standards. E. coli concentrations were found to be correlated positively with precipitation and turbidity. A linear regression model was applied, that explains large part of the variation in E. coli concentration (R2 = 0.42). Water quality index assessment was also ranked the water quality as ‘poor’ category; indicate that the water is unsuitable for uses in domestic and recreational purposes and high health risks involved with the water use. The study findings highlight the problem of untreated sewage discharge into the rivers. Implementation of sewage treatment plant with adequate capacity is highly recommended.

This study demonstrates the aspects of research and mining in groundwater mining. It was intended to demonstrate the guidelines of the Mining Code and Water Code as legal beacons under the management of the National Mining Agency – ANM, federal regulator of mineral water exploration; to analyze the importance of water quality control for human consumption, from the compliance with Anvisa Resolutions – RDC-274/275/2005, which standardize the vase and microbiological characteristics. The process to make groundwater available as a mineral good to be industrialized, goes through research stages, till the final test with laboratory analyses for water classification. In this context, its main question is: what is the importance of mineral water quality for human consumption in health promotion? And it aims to analyze the quality control of mineral water, its importance for human consumption and health promotion, as well as the benefits of it. For this, a bibliographic research was carried out, consultation with the relevant legislations, books and websites of public agencies. The results showed that mineral water mining is an activity present in the daily life of society and its regular consumption contributes to the quality and promotion of healthy living, through control of the exploitation of mineral water mines, under the management of the National Mining Agency – ANM. It was evidenced that mineral water brings important health benefits: in body thermoregulation, heat absorption, nutrient transport, oxygen, hormones, composition of blood plasma, digestive juice, saliva formation, tears and urine. Being composed of different levels of micronutrients, which help alleviating health problems, such as: weakening of bones and muscles, reduction of collagen, dryness of the skin, low revitalization of cells and mucosa, aggravated by low consumption of water with drug properties and product of secular use that affect health. It was concluded that the prevalence of each type of mineral water and its composition, from ferruginous, sulfurous, radioactive, magnesian and iodized, can help in therapeutic treatments.

The quality of water is crucial for the qualification of river beaches. The Cávado River watershed (Northern Portugal) contains five river beaches with a regular and specific mandatory monitorization. The main subject of this research is the evaluation of spatial and temporal water microbiological and physicochemical parameters to assess the water quality improvement and consequently watershed management. The results of monitoring surface water, considering microbiological parameters from the five river beaches (2015/19), and physicochemical parameters from three water points along the Cávado River (2018/19) were considered. The river beaches located upstream of the town of Braga has an “excellent” and “good” quality, while the river beach located downstream shows a lower water quality. The physicochemical water results indicated that there is a progressive degradation of water quality from upstream to downstream of the river, which is associated with the influence of domestic and industrial activities. To improve water quality, continuous monitoring will be necessary, with the implementation of adequate awareness-raising programs and strategic water quality management by the population and local agents.

Some springs in Awing, North West Cameroon, were assessed in order to ascertain their quality for human consumption. Achialum, Meupi, and Ala’amiti quarters in Awing depend on springs as the major source of drinking water and inhabitants consume it in its natural state without prior assessment and treatment. Water samples were collected from Achialum, Meupi, and Ala’amiti and analysed for organoleptic, physicochemical, and bacteriological parameters using standard methods. Results of organoleptic and physicochemical parameters showed that most of the parameters fell below WHO limits. Water quality index results, based on physicochemical parameters only, showed that Achialum and Ala’amiti springs were of good quality while Meupi spring was of poor quality. Water quality index may not carry enough information about the real quality situation since a single bad parameter value can give misleading information about the water quality. However, the bacteriological aspect revealed the presence of faecal coliforms and pathogenic bacteria in all the springs that justified the high rate of water borne diseases recorded in the area. This poor water quality could be associated to poor hygiene and farming practices. Thus, the population of Awing should implement home water treatment methods such as boiling, filtration, or chlorination before consumption.
