Despite all efforts to store and reduce its consumption, water is becoming less inexhaustible and its quality is falling faster. Considering that water is essential to animal life, it is necessary to adopt measures to ensure its sanitary conditions in order to be fit for consumption. The aim of this study was to analyze the microbiological quality of drinking rainwater used by rural communities of Tuparetama, a small town located in Northeast Brazil. The study covered seven rural communities, totaling 66 households. In each household two samples were collected, one from a tank and the other from a clay pot located inside the home, resulting in 132 samples (tank plus clay pot). Approximately 90% of samples were below the standard recommended by the current legislation, being considered unfit for human consumption. Part of this high microbiological contamination of drinking rainwater could be related to the lack of sanitary education and of an adequate sewerage sanitation system.

Rainwater harvesting (RWH) for drinking water production has been a potential solution to mitigate water scarcity in rural areas. There was limited research focusing on the quality of treated rainwater. This study developed and tested the quality of a drinking water filtration system (DWFS) for treating harvested rainwater to support rural communities.

Urban stormwater and rainwater in water-stressed cities serve as critical vectors for the transport and dispersion of pollutants, including very mobile compounds These pollutants, which can be influenced by factors such as land use, rainfall intensity, and urban infrastructure, pose significant risks to both human and environmental health. Although several priority pollutants have traditionally been detected in urban stormwater, little is known about the presence of very mobile compounds that may threaten urban drinking water supplies and pose environmental risks to aquatic species. In this study, 131 urban rain and stormwater samples were collected from three districts of Barcelona (Spain) and analysed for 26 very mobile pollutants that are often overlooked in conventional monitoring efforts.

This study aimed to measure tritium (3H) concentrations in Thailand. Nationwide tap water samples were collected in July 2021. Rainwater samples were collected monthly during May-October 2020, April-October 2021, and February-March 2022 in Chonburi province and in Chiang Mai province during July-November 2021, January 2022, and March-June 2022.

The Fukushima Daiichi Nuclear Power Plant (FDNPP) accident created large stockpiles of tritium containing cooling water, which is to be gradually released into the Pacific Ocean, gaining attention from surrounding countries, environmental groups, and local residents concerned with the possibility of increasing tritium concentrations in the water and food cycle. Establishing baseline concentration levels and monitoring tritium immission values are important for assuring public safety, providing data for scientific research and risk communication. Tritium concentrations in the environment are very low; therefore, tritium measurements require enrichment in order to estimate the radiation exposure from drinking water intake and provide information on the water cycle.
