“…At consumer taps, organic matter concentrations may increase due to contamination (such as soil and fecal matter) that may enter improperly covered storage containers. – Microbial growth during consumer water storage can increase the level of biological organic matter and potentially worsen microbial water quality. , Greater microbial activity attributed to an increased level of organic matter may increase the level of DBP formation through the formation of biological DBP precursors, or it may decrease concentrations through an increased level of biodegradation . Therefore, long stagnation periods in stored water could lead to an overall decrease in the level of nitrogenous compounds if there are no sources of contamination.…”

Intermittent water supply (IWS) is found in many parts of the world, especially in low- and middle-income regions, and is characterized by a loss of distribution system pressure, periods of stagnation, the intrusion of contaminants, repressurization of the piped system when service is resumed after a no-supply period, and the need for consumer water storage. Although we have a robust understanding of the impacts of IWS on microbial water quality, less research emphasis has been placed on the impact of intermittency on chemical water quality, such as the formation of disinfection byproducts (DBPs). Chemical disinfection is commonly used to remove or inactivate waterborne pathogens during drinking water treatment and distribution to protect and improve microbial water quality. However, characteristics of IWS have known or suspected contributions to factors that impact DBP formation during drinking water distribution and household storage, such as the intrusion of organic matter, variable post-chlorine water ages, and growth and/or regrowth of microbial communities. This review discusses the impact of IWS on the formation and fate of DBPs, drawing upon the literature regarding continuous water supply systems and key characteristics of IWS. We call for more frequent monitoring of DBPs in IWS and further investigation of the mechanisms affecting DBP formation and speciation under various IWS conditions.

“…On the other hand, due to the importance of the addressed topic, water quality (Varol, 2020;da Luz and Kumpel, 2020;Cui et al, 2020;Wang and Zhu, 2021;Katarzyna and Janusz, 2020), and its direct influence on household consumers' health, as well as, to the fact that the chosen types of filters are widely used and can be purchased from the national network of stores, scientific structured data, statistically interpreted, such as the one encompassed in this research should be made available to the public, in order to provide the interested consumers with the required information to truly achieve a high-quality level of drinking water in their own household (Ma et al, 2022;Khan and Sheikh, 2023;Larson et al, 2023).…”

The study shows the findings of a microscopic examination of samples of filtered water obtained using five different types of filters. The novelty of the approach to the research carried out in this paper consisted in using of a statistical mathematical model that confers increased accuracy on the resulting values, with the aim of characterizing the efficiency and quality of drinking water filters intended for the general public for domestic consumption at the national level. Atomic force microscopy was used to carry out the analysis, and particular mathematical models were used to statistically evaluate the findings. The paper explains the methodology used, including details on the laboratory setup, the steps finished, and the tools used to accomplish the suggested goals. With an emphasis on the three dimensions of the particles—height, diameter, and arithmetic roughness—the findings from the microscopic analysis of the particle deposits on the filtered water samples are given and tabular indexed. As a result, it was feasible to use a computational mathematical model to identify the statistical indicators of the values recorded in the samples that underwent microscopical analysis. Following the application of the mathematical model, the findings were centralized, and their correlation was analyzed using graphical representations. The results led to the concrete identification of the impurity degree of drinking water filtered by consumer means.
