Abstract Access to safe water, proper sanitation, and hygienic practices are fundamental to the growth and survival of children. This study assessed the relationship between water, sanitation, and hygiene (WASH) practices and the nutritional status of children aged 6–59 months in the Beere/Oja-Oba community, Ibadan, Oyo State. This cross-sectional study involved 200 mothers/caregivers with under-five children. WASH practices were assessed using an interviewer-administered questionnaire. Anthropometric measurements were taken and analyzed using WHO Anthro. Data were analyzed using SPSS at p < 0.05. The mean age of the children was 24.91 ± 10.52, and the majority were females (77.5%). The prevalence rates of stunting (44.0%), wasting (37.5%), and underweight (34.0%) were high among the children. Well (71.5%) and tap/borehole (74.0%) were the major sources of domestic and drinking water, respectively, and required 5–15 min (36.9%) to source. The occurrence of diarrhea was high (48.5%) among the children. Time to drink water source and wash child's hands before feeding were WASH practices significantly associated with stunting (p = 0.000) and underweight (p = 0.003) among the children from lower socio-economic households (p = 0.045). Access to unsafe water was significantly associated with malnutrition among the children. There is a need to educate and encourage mothers/caregivers to improve their hygiene practices in the community.

Abstract In Nigeria, the widespread lack of access to water, sanitation, and hygiene (WASH) represents a critical public health challenge. Yet, the socioeconomic determinants of WASH access at the national level remain poorly understood. This study uses 2018 Nigeria Demographic and Health Surveys (NDHS) cross-sectional data to investigate the socioeconomic factors associated with WASH access. The majority of survey respondents lived in rural areas (57%); used an improved source of drinking water (73%) and an improved sanitation facility (55%); and did not treat their drinking water (92%). Binary logistic regression showed that Nigerians living in rural areas were less likely to have access to an improved water source (p < 0.001, OR = 0.42 [0.41, 0.44]) and less likely to have access to an improved sanitation facility (p < 0.001, OR = 0.79 [0.77, 0.81]). A sub-group regression analysis of respondents without access to improved WASH found that rural residence (OR = 0.84 [0.76, 0.93]), along with lower levels of education and wealth were associated with non-treatment of their unimproved drinking water. This study suggests that efforts are needed to increase WASH access in rural areas and to improve household water treatment in areas without access to improved water and sanitation.

Abstract Point-of-use (POU) drinking water treatment is crucial for residents in resource-constrained areas. This study introduces a layered double hydroxide (LDH) foil, an innovative POU device that eliminates waterborne pathogens via adsorption. It is an aluminum foil coated with magnesium–aluminum (Mg–Al)-type LDH, a recognized human-safe pathogen adsorbent. Its sheet-like morphology enables easy retrieval of inherently powdered LDH from post-disinfected water. Coating with Mg–Al LDH foils was accomplished by immersing aluminum foils in alkaline magnesium solutions, resulting in the on-surface formation of LDH. Using 12 distinct alkaline magnesium solutions, 12 types of LDH foils were prepared. Most LDH foils demonstrated >99% removal of Escherichia coli (DH5α strain) within 3–24 h when 100 mL of water was inoculated with DH5α at approximately 103 colony-forming units (CFU)/mL agitated with a 25-cm2 LDH foil piece. The LDH foil with the highest efficacy had a maximum adsorption capacity of approximately 1.3 × 106 CFU per 1-cm2 LDH foil. Furthermore, the LDH foil was regenerated by submersing it in the alkaline solution during its preparation, enabling multiple reuses. Owing to its straightforward production and application, the LDH foil holds substantial promise as a convenient-to-use adsorbent for batch water disinfection, such as jug water, in rural households.

Abstract Rivers are important freshwater sources. They provide water for domestic and recreational use and serve as ecological sites for various microorganisms. Free-living amoebae are considered naturally occurring organisms in freshwater. However, their prevalence can suggest the water quality at a given source. Forty-five surface water samples from nine different sites were collected from the Marikina River. Samples were processed and cultured in non-nutrient agar (NNA) lawned with Escherichia coli, and were observed for 14 days using a light microscope. Thirty-six (80%) samples yielded a positive amoebic growth. Further molecular testing confirmed the presence of Acanthamoeba spp. using specific primer sets, JDP1 and JDP2. The current results of this study have shown a remarkable jump in the detection rate for free-living amoebae (FLAs). The continued deterioration of the Marikina River due to several human and non-human factors may have been the reason for this phenomenon. River clean-up, resettlement programs, and strict implementation of laws on waste disposal should be considered to rehabilitate the Marikina River.

Water, sanitation, and healthcare waste management are essential services in healthcare facilities to ensure the quality of care and minimize infection risk. World Health Organization (WHO) Cox Bazar's sub-office supported the implementation of the Water and Sanitation for Health Facility Improvement Tool in 21 purposively selected HCFs in Rohingya refugee settlements. A total of 16 WASH FIT indicators from three of the seven WASH FIT domains (five on water, five on sanitation, and six on health care waste management) were monitored for 1 year employing a mixed method approach. After 1 year 67% of indicators in all three domains met minimum WASH FIT standards, indicating a significant (p ≤ 0.01) contribution to improved quality of care compared to 29% at the start in August 2018. By domain, 81% of water indicators (vs. 67% at the start), 76 vs. 24% for sanitation, and 48 vs. 33% for healthcare waste management met standards. Key informant interviews and focus group discussions affirm improvement in all three domains, including quality of care, staff satisfaction, and awareness of occupational risks and mitigation measures. Challenges remain, including limited budget, lack of leadership and absence of formal programs for improving water supply infrastructure, sanitation and health care waste management.

Abstract Good health and well-being require safe drinking water and improved sanitation facilities. Lack of access to drinking water and sanitation facilities poses serious health risks. There are few studies based on the NFHS-5 data in the literature. Therefore, the present study used the NFHS-5 data to investigate the spatial distribution of limited access to drinking water and sanitation facilities in India. The Stata version 14.1 software was used for statistical analysis and Arc Map 10.4 was used for spatial analysis. A binary logistic regression model was applied to investigate the association between dependent and independent variables. The prevalence of limited access to drinking water and sanitation facilities was higher in Madhya Pradesh (12.28%) and Manipur (22.65%), respectively. Besides, the spatial distribution of limited access to drinking water and sanitation facilities was spatially clustered among a few central and western Indian states. In the binary logistic regression, education, wealth index, and place of residence were significantly associated with limited drinking water and sanitation services. There is regional heterogeneity in drinking water and sanitation services. With this in mind, we suggest spatially optimized target-oriented policy measures in unprivileged areas. Improving the water distribution networks and construction of sanitation facilities is also recommended.

Abstract Latrines are an effective way for people in low- and middle-income countries to move away from open defecation. Guidelines are used to provide a recommended horizontal setback distance from a latrine to a downgradient well to ensure the safety of the well from subsurface contaminants. We collected 107 journal papers, books, and reports to critically review the recommended setback distances and how these recommendations are derived. It was discovered that the four most common guidelines/reviews are all based principally on just four field studies, all of which were conducted over 40 years ago, which casts doubt on a frequently used one-size-fits-all approach. More recent methods for latrine siting use both field data and some sort of modeling component to account for the different site conditions, but these models have not been verified for use outside their respective studies. They are also limited in how they consider the hydraulic connection between the latrine and the well. We recommend that future siting guidelines should focus more on vertical separation, include chemical contamination, and be based on models describing how latrines and wells are hydraulically connected, along with the fate and transport of potentially harmful contaminants.

Abstract Water access, sanitation and hygiene (WASH) data for Malaysia suggest that almost 100% of the population have access to basic sanitation and basic drinking water, but this data may not include marginalised communities and stateless individuals, indigenous or otherwise. The aim of this study was to evaluate WASH provision for residents of the Johor River Basin and evaluate the disparity in facilities between indigenous Orang Asli and more modernised communities. Questionnaires were distributed to eight communities. In total, 899 questionnaires were completed including 100 from indigenous communities and 799 from more modernised communities. Significant differences existed between communities with regard to education levels (p < 0.001), occupation (p < 0.001), household income (p < 0.001), type of toilet, sewage and sanitation facilities (p < 0.001) and perception of health risks and concerns (p < 0.001). There is a significant difference in access to water and sanitation facilities between indigenous and modernised communities. Further study is now required to understand behaviours and educate river-based communities on relevant potential health risks from water contamination in the Johor River Basin.

Abstract Achieving safely managed sanitation (SMS) in rural areas has spurred innovation in toilet designs that provide on-site treatment of fecal sludge (FS), including the development of International Development Enterprise (iDE)’s alternating dual-pit latrine upgrade (ADP). ADPs treat FS by inactivating pathogens using storage treatment with lime; however, ADPs’ reduction in pathogenicity (and thus their associated public health benefit) has not yet been described in real-world pits at scale. We thus enumerate the fecal indicator bacteria Escherichia coli (E. coli) and fecal coliforms in 147 pits after two years of storage treatment with lime and compare detected concentrations to relevant standards. E. coli and fecal coliform concentrations indicated a risk to human health in 31% and 42% of sampled pits, respectively. Regression models described relationships between fecal indicator bacteria concentrations and measured factors (e.g., sludge pH, temperature) but did not reveal any meaningful associations. High rates of pit ineligibility also indicate that many ADPs are not operated as recommended. Results indicate a one-in-three chance that a household emptying their own pit would be exposed to health hazards and call into question the effectiveness of the standard two-year storage treatment in real-world applications. To improve rural SMS, various evidence-based recommendations are made.

ADPs treat FS by inactivating pathogens using storage treatment with lime; however, ADPs’ reduction in pathogenicity (and thus their associated public health benefit) has not yet been described in real-world pits at scale. We thus enumerate the fecal indicator bacteria Escherichia coli (E. coli) and fecal coliforms in 147 pits after two years of storage treatment with lime and compare detected concentrations to relevant standards. E. coli and fecal coliform concentrations indicated a risk to human health in 31% and 42% of sampled pits, respectively. Regression models described relationships between fecal indicator bacteria concentrations and measured factors (e.g., sludge pH, temperature) but did not reveal any meaningful associations. High rates of pit ineligibility also indicate that many ADPs are not operated as recommended.

Abstract School-based water, sanitation and hygiene (WASH) promotion often lacks strategies to sustain behaviors beyond the promotion period. This paper describes school community engagement, in the form of a hygiene committee to institutionalize a school-based hygiene intervention and its role in implementation and sustainability. With formative data on existing hygiene practices from four urban and rural elementary schools, we arranged a workshop to design a low cost, acceptable, and feasible hygiene intervention. We formed hygiene committees including student representatives in each of four additional schools, and piloted and assessed the hygiene intervention. The hygiene committee members' active role supported intervention facilities, materials and maintenance, and promoted targeted behaviors. They encouraged continued use of hygiene materials and provided funds to cover the cost of consumables. The teachers' commitment, student motivation, and financial cost recovery facilitated continued intervention activities. During the 14-months follow-up assessment, the hygiene committee activities were still in place in all schools. The dual involvement of teachers and students in hardware maintenance ensured hygiene intervention consumables availability, functionality, and retention in the pilot schools. The hygiene committee facilitated intervention implementation and sustained functionality. Future school interventions should consider this approach in the implementation processes and cost-recovery strategies.
