Summary: The study focused on investigating pollution levels in open wells, bore wells, and drinking water from riverine community sites. The suitability of the water for drinking and irrigation was assessed using user-specific water quality indices and parameters quality index. Principal component analysis was also performed to analyze the physio-chemical parameters. Most of the water quality parameters showed notable variation, with some exceeding the standards set by authorized organizations. The drinking water samples were found to be of good quality for human health and hygiene, but none were excellent. The open and bore well water samples were generally suitable for agricultural purposes, with a few exceptions that were of poor or fair quality.

Summary: Intermittent water supplies have a significant impact on biofilm growth and can lead to water quality degradation, especially events lasting more than 6 hours which generate more turbidity responses and hence discolouration risk. Additionally, shorter times of non-water supply may increase the risk of aromatic organic compounds and potential pathogenic microorganisms, highlighting the importance of managing microbial interactions to ensure continued safe water supply.

Summary: Universal access to safe water is a major global goal, but the quality of drinking water sources in developing countries is becoming a concern due to potential pollution sources. While most water samples from rivers, water distribution systems, and tankers meet drinking water standards, higher levels of cadmium and other metals in the eastern part of the city suggest corrosion within the water distribution system. Regular consumption of certain brands of bottled water may lead to increased exposure to arsenic and mineral deficiencies.

Summary: Drainage water recycling (DWR) using drainage and subirrigation (DSI) has improved crop production and water quality in the midwestern United States. However, the effects of DWR on soil properties and soil health parameters have not been determined. This research evaluated the nutrient concentrations in a DWR site over time, the effects of DWR on soil properties, and the influence of DWR on soil health parameters after a long-term corn-soybean rotation.

Summary: Understanding the microbial ecology of drinking water systems is crucial for providing safe water. This study investigated the effects of intermittent water supply on bacterial communities in a neotropical drinking water system. The results showed that the bacterial diversity and composition changed during the treatment and distribution process, and unique bacterial taxa were found during the restart of intermittent water supply. Pseudomonas was found to be more common in intermittent water supply samples. These findings highlight the important changes in water bacterial communities caused by intermittent water supply.

Summary: Understanding the microbial ecology of drinking water systems is crucial to delivering safe water. This study used rRNA gene metabarcoding and traditional measurements of water quality to assess the impact of continuous and intermittent water supply on bacterial diversity and composition in a neotropical drinking water system. The results showed that changes in water supply significantly influenced the microbial communities.

Summary: This article investigates the impact of the largest roads in Poland on groundwater quality and evaluates the extent of their influence. The study finds that the groundwater quality near roads may be negatively affected, as indicated by the increased concentrations of chloride and sodium ions. The findings are important for a deeper understanding of the environmental impact of road transportation.

Summary: Improving access to water, sanitation, and hygiene services in rural areas can significantly reduce E. coli concentration in drinking water. However, installing piped water systems did not show any impact on hand contamination. While the systems improved the accessibility of safe drinking water, there were only minor improvements in microbiological outcomes and no changes in the duration of in-home water storage.

Summary: This study evaluates the potential of utilizing existing water supply infrastructure as small-scale pumped hydroelectric storage (PHS) units to reduce steep power ramps caused by renewable energy penetration. The analysis shows that the seasonal pattern of storage capacity is in accordance with the behavior of the corresponding hydraulic head timeseries, with higher values in winter/autumn.

Summary: This study applied chemometrics to analyze water quality data from three major river basins in Selangor, Malaysia. The results showed spatial and periodic variations in pollution characteristics. Nitrogen species, total suspended solids, and dissolved solids were identified as the major pollution loads, with a significant increasing trend in ammonia pollution. The study highlights the vulnerability of Selangor's water resource system to water pollution and suggests incorporating ammonia treatment facilities into water treatment plants for smooth water supply operations.

Summary: Throughout history, the Drave mountain village in North Portugal has faced challenging hydrological conditions. This study examines the evolution of water demand and supply in Drave village from the 16th century to the present day, and proposes a possible solution for future water needs. The analysis reveals two historical periods in water demand and supply, with the current scenario relying on contaminated water resources to meet temporary residents' needs. A potential solution involves utilizing surface water during the wet season and exploiting stream alluvial deposits during the dry season.

Summary: Teachers generally support the idea of performance pay, with a majority of parents also preferring it over school grants. Exposure to a performance pay program has a limited positive impact on teacher support for performance pay, and does not adversely affect the work environment in schools.
