This study assessed the impact of sanitation practices, hygienic and storage conditions on the quality of drinking water treated at point-of-use in Makwane Village. Subsequent to implementation of low-cost Household Water Treatment Devices which are the biosand filter with zeolite-silver (BSZ-SICG) and silver-impregnated porous pot (SIPP) filters in Makwane village, a structured questionnaire was designed to collect the following information: age of caretakers, number of children under the age of five, water storage conditions, sanitation amenities, and hygiene practices. Water quality from the sources to household level was assessed using culture-based and molecular techniques. The results revealed a significant association between the presence of Escherichia coli in treated drinking water with the age group of caregivers and the number of children ofless than the age of five [OR (95% CI) = 8.4737 (0.147–3.3497), p = 0.0141923 and OR (95% CI) = 9.1667 (0.1848–3.0159); p = 0.0165830, respectively]. Moreover, significant association was noted between hygiene practices (washing of hands with/without soap) and water quality in storage containers [OR (95% CI) = 16.000 (0.6763–3.9495), p = 0.0000125]. These findings further prove that there is still a dire need for reconsidering hygiene education in rural areas as the health benefits of water treated at point of use (POU) coupled with safe-storage condition interventions might not be guaranteed without proper hygiene. The results further highlighted the importance of washing hands in improving microbial quality of drinking water, which is the key factor for fighting against infectious diseases.

Abstract Determining the microbial quality of drinking water by assessing the presence/absence (P/A) or enumeration of indicator bacteria continues to be widely practiced worldwide. However, rapid tests are required for microbiological water quality assessment so that the information is available in the shortest possible time for initiating a timely intervention. Traditional methods for the enumeration of indicator bacteria are not only expensive but also need trained personnel. We have developed a low-cost kit, MColiPAT, and have validated its application for detection of coliforms in drinking water using the IDEXX Colilert-18 Quanti tray method. MColiPAT kit medium was able to detect coliforms down to a level of 3.1 MPN/100 ml within 10.5 hours. The sensitivity and specificity of the kit were 95.45% and 100% respectively. MColiPAT is found to be reliable and accurate for the detection of coliforms in drinking water.

This research aimed at assessing the drinking water quality of piped water distribution in Jimeta-Yola Adamawa State, Nigeria. The strategy was based on establishing the possibilities of contaminants underlying the distribution channels compromising the quality from the treatment source to the consumer point of use. Selected heavy metals and physiological parameters were determined toward establishing the water quality indices (WQI). Though, most of the parameter determined fell below or within the permissible limits (PL) set by WHO for drinking water, the results indicated significant (p<0.05) differences in the concentrations determined in the treatment plants (Yola treatment plant (YTP) and Jimeta treatment plant (JMTP)) with those at the consumer endpoints (YTPC and JMTPC). The results showed the WQI at the treatment plants being compromised due to the induction of pollutants across the distribution pipes. The water samples at the treatment point (JMTP) were excellent, having WQI <25 and good quality at YTP (25< WQI<50). However, the water quality on leaving the treatment source was observed to slightly change to poor quality at JMTPC (WQI= 57.00), and further observed to be in moderate-good quality at YTPC (WQI=49.27). Further analysis showed an increase in bacterial counts in the water samples at the consumer points.  Escherichia coli concentrations of 565 and 718 cfu /100 mL were detected in samples from YTPC and JMTPC, despite the fact the water was observed to be free from bacteria at the treatment plants.

In this paper, the authors analyze the drinking water quality of Peshawar city due to which authors concluded that water quality assessment of 18 locations inside Peshawar of various union council. Groundwater samples were collected from a tube well and subjected to physical, chemical and biological analysis to check their suitability for the purpose of drinking. Results exposed that out of 18 samples 10 samples of water were found unfit for drinking purposes. In the 10, samples most of the effect on the water quality was from the chemical and biological contamination. It is concluded that the old defective supply system, infrastructure and storage, as well as their lack of maintenance are the reason behind the pollution of drinking water in Peshawar.

Background: Accessibility to potable water is a fundamental right for dignity and well-being. Despite this observation, more than 1.1 billion people lack access to safe drinking water. This is particularly true in the Sub-Saharan Africa and South East Asia regions. Objective: The main aim of this study was to assess microbial quality of drinking water and prevalence of water-related diseases in Marigat town, Baringo County, Kenya. Methods: Samples of drinking water were collected from water sources (boreholes, rivers, and wells) and at the point of use (households) and analyzed for Escherichia coli and total coliform (TC) bacteria using the most probable number method. In situ measurements of pH and temperature were performed using a Wagtech International portable meter. Clinical health records from the local health centers were also reviewed to assess the prevalence rates of some of the water-related diseases. Results: There were significant differences among water sources during dry season for E coli (F2,21 = 3.629, P < .05) and TC (F2,21 = 4.041, P < .05). Similar observations were made during wet season for E coli (F2,21 = 4.090, P < .05) and TC (F2,21 = 1.893, P < .05). Furthermore, there were significant interactions between the water sources and season for E coli (F2,42 = 7.66, P < .01) and TC (F2,42 = 5.494, P < .05). Drinking water in large plastic storage containers (herein referred to as sky-plast) had the highest E coli and TC concentrations. Typhoid was the most prevalent water-related disease during the dry season (10%), whereas diarrhea (3%) was the most prevalent during the wet season. Conclusions and recommendations: All drinking water at abstraction and point of use for Marigat residents are microbiologically contaminated and therefore pose serious health risks to consumers of such water. Thus, there is need for public health awareness campaigns on household water management to curb incidences of water-related diseases. Public health practitioners at county and national levels need to ensure that households have adequate access to potable water and improved sanitation.
