Monitoring the quality of the water used in mobile dialysis services in intensive care units in the city of Rio de Janeiro

Abstract Introduction: Monitoring water quality in mobile dialysis (MD) services, assessing critical points and characterizing the risks inherent in the process, is essential to avoid risks to the patient's health. This study evaluated the microbiological quality of water in the MD of 36 hospitals with intensive treatment in the city of Rio de Janeiro. Methods: 204 water samples were collected from the points of entry to the network (NET), post-osmosis (PO) and dialysis solution (DS). The samples were evaluated for heterotrophic bacteria count, pathogen search, presence of endotoxins and aluminum content. Results: Bacterial contamination at 3 collection points in 36 hospitals was 30% (32/108); 42% from DS, 31% from PO and 17% from NET, with the presence of Pseudomonas aeruginosa, Stenotrophomonas maltophilia , Burkholderia cepacia and Ralstonia pickettii in the 3 points. Endotoxin concentrations above 0.25 EU/mL occurred in 77% of the samples (17/22) analyzed in the PO. In the aluminum content, values above 0.01 mg/L were presented in 47% (7/15) of PO samples and 27% (4/15) of NET samples. There is no specific legislation for water used in the MD; therefore, the limits of the RDC of the National Health Surveillance Agency (Anvisa) 11/2014 were used; which regulates conventional hemodialysis services. Conclusion: The results highlight the importance of evaluating water quality in MD services to ensure patient safety and support the sanitary monitoring of this process as a healthcare promoter.

This study aims to characterize, in terms of physicochemical, bacteriological and metal concentration parameters, the water quality of public fountains in the city of Salvador (Bahia, Brazil), in order to identify its potential for current uses, contributing to the diagnosis of water quality on the public access. Therefore, campaigns were conducted in July and November of 2017 and 2018 in four fountains (Fonte Nova, Estica, Pedrinhas/Pedreiras and Express way), which were geo-referenced and analyzed physical-chemical parameters (pH, conductivity, temperature, dissolved oxygen, turbidity and total dissolved solids, salinity, sulfate, nitrate, chloride and alkalinity), bacteriological (thermotolerant coliforms) and metals (Cd, Pb, Ni, Co, Cr, Cu, Zn, Fe, Mn). The fountains showed values in disagreement with the CONAMA Ordinances 396/2008, 357/2005, and 274/2000 mainly about the pH, Dissolved Oxygen, Nitrate and Thermotolerant Coliforms parameters, indicating inadequacy for their intended uses. This information should support decision making and mitigation measures that minimize the environmental degradation of urban fountains in the city of Salvador (BA), from the adoption of recovery, revitalization and monitoring measures that enable the effective management of these water resources.

Storage Containers

Studies in Southern Africa have shown that even when microbiologically safe water is supplied to developing communities at communal standpipes, contamination by high numbers of pathogenic microorganisms may occur during the processes of fetching water from the supply source and storage during use at home, rendering such waters unsafe for human consumption. This study investigated the occurrence of biofilm in PVC storage containers as one possible reason for this deterioration, using heterotrophic bacteria and total coliform counts as well as turbidity as indicators. A second objective was to determine whether biofilm in water-storage containers could contribute to hazardous microbiological contamination indicated by Escherichia coli and Clostridium perfringens. Results indicated that increased microbiological contamination is associated with biofilm. The biofilm harbours heterotrophic bacteria, total coliforms and C. perfringens. E. coli could not be associated directly with the levels of biofilm in containers but rather appears to be introduced intermittently from the ambient domestic environment. When dislodged with the biofilm, these bacteria contributed substantially to the deterioration of the microbiological quality of supplied water stored in plastic containers.

However, since the Lake is an open system that can also be utilized for the certain provisions tailored to support power and capacity of the Lake. One of the supported power and capacity of the Lake is the availability and quality of the water of the Lake. Sipin lakes located in the city of Jambi, have long been exploited by various parties, just that its utilization is not maximal for a variety of activities. To maximize its utility it is necessary to know the power support and power tampungnya. By knowing the power support and power tampungnya then it can be determined the allocation it is used so that will give you maximum results.

Drinking water is one of the most essential human needs. The purpose of this study was to investigate the status of the water quality of PDAM Giri Menang as a source of drinking water for people in Mataram area based on physical, chemical, and microbiological parameters. Determination of sample points was done by random sampling method while the samples were collected by using composite sample method. The results of analysis of physical parameters (odor, taste, turbidity, temperature, color), chemical parameters (dissolved oxygen, iron (Fe), pH, hardness, manganese (Mn), chloride (Cl-), ammonia (NH4), cadmium (Cd) ), and the microbiological parameters including the presence of E.coli bacteria and total Coliform in the five PDAM water samples generally meet the quality of drinking water since the value of each parameter was below the maksimum value set by Permenkes RI No. 492/2010 concerning requirements quality of drinking water. The conclusion from the research results shows that the status of water quality PDAM Giri Menang as a source of drinking water for people in Mataram area is very good according to the mandatory parameters, namely physics, chemistry, and microbiology that are in accordance with the Republic of Indonesia Minister of Health Regulation No. 492/2010 regarding the requirements for the quality of drinking water. The results of this study can be used as a reference for further research with more samples and parameters, especially in the city of Mataram and West Lombok.

The contamination of vegetables by pathogenic microorganisms is directly related to the water quality used in their irrigation. Lettuce is the main vegetable consumed in Brazil and because it does not undergo any processing before its consumption, it is directly affected by the quality of the water used for irrigation. This study analyzed the physical-chemical and microbiological quality of water used in lettuce irrigation and possible microbiological contamination of lettuce. In relation to microbiological analyzes, high values were found for heterotrophic bacteria and total coliforms in weirs and vegetables. For fecal coliforms, in almost all water samples, the value found was above that established by the legislation. In lettuce, this occurred in three samples. No strong correlation was found between water and lettuce contamination. In relation to the physicochemical parameters analyzed, only the value of the turbidity in one of the weirs was above the threshold established by the legislation.

In many developing countries, the scarcity of potable water is an ongoing challenge. Even when water is plentiful, its quality may be unsuitable for household use such as in the city of Kinshasa in the Democratic Republic of Congo (DRC) which is the study area for this investigation. Shortage of potable water has forced inhabitants in the city to rely on water wells dug without adherence to regulations or specifications within perimeters of their homesteads. The water from such wells is often polluted with household waste being generally disposed by burning and burying in shallow pits, thrown in pit toilets or into rivers. Such practices have led to contamination of ground water. This study examines the water quality of drinking water drawn from wells in Fer-bois, which falls under the Kimbanseke municipality in the South East of Kinshasa. The dynamics of well design/location, sources of possible contamination with respect to water treatment and water quality as well as its possible impact on health are examined. The area was shown to have poor groundwater quality with significant amounts of pollutants such as NO3, Pb and Cd leading to environmental and health concerns.
