Water and sanitation

Water and sanitation are pivotal elements of the Sustainable Development Goals (SDGs), primarily encapsulated in SDG 6 (Clean Water and Sanitation). This goal seeks to ensure the availability and sustainable management of water and sanitation for all by 2030. This objective directly addresses the current global water crisis, where nearly 2.2 billion people live without access to safe water, and about 4.2 billion lack access to adequate sanitation.

By focusing on improving water quality, increasing water-use efficiency, implementing integrated water resources management at all levels, and protecting and restoring water-related ecosystems, SDG 6 addresses not only direct human needs but also the broader ecological health of the planet. Furthermore, efforts towards achieving SDG 6 indirectly promote several other SDGs.

For instance, water and sanitation are crucial to achieving SDG 3 (Good Health and Well-being), as clean water and proper sanitation facilities reduce the spread of water-borne diseases and significantly lower child and maternal mortality rates. Likewise, they are foundational to SDG 4 (Quality Education), given that the provision of water and sanitation facilities in schools significantly impacts the attendance and performance of students, particularly for girls.

SDG 2 (Zero Hunger) also intersects with water and sanitation, as sustainable and efficient water management is critical for agriculture, which remains the largest global water consumer. The necessity of water for food production and the potential impact of improved water management on crop yields and livestock health makes SDG 6 integral to achieving zero hunger.

SDG 6 contributes to SDG 1 (No Poverty) and SDG 8 (Decent Work and Economic Growth) as well. Access to clean water and sanitation can enhance economic productivity by reducing time spent gathering water, reducing healthcare costs due to water-related diseases, and even creating jobs in water and sanitation services sectors.

In terms of environmental impact, the sustainable management of water resources is essential for SDG 13 (Climate Action), as water is a key factor in managing climate change due to its role in agriculture and energy production.

This content advances SDGs 12 and 13 by promoting responsible water resource consumption in pastoral lands and working with the environment rather than against it to raise livestock. Raising livestock responsibly and sustainably promotes SDG 2 for zero hunger as well.
Hazard classifications have recently been introduced for persistent, mobile and toxic (PMT) and very persistent and very mobile (vPvM) substances, which are those that negatively impact water resources if substantially emitted into the environment. Many pharmaceuticals and personal care products (PPCPs) may meet this classification. Our study focused on 169 detected PPCPs in surface water, groundwater and drinking water in China among a total of 432 PPCPs that were monitored for across 75 studies.
Potential transport pathways of asbestos fibers in groundwater from contaminated sites.
To prevent exposure of millions of people living near thousands of contaminated sites to asbestos, the sites are typically capped with soil and amendments, assuming asbestos mobility underground is negligible in all conditions. Here, we disprove this long-standing assumption and showed that the presence of certain types of dissolved organic matter (DOM) can facilitate the transport of the asbestos fibers through packed sand or soil columns.

Vinyl chloride (VC) and 1,4-dioxane (DX) are carcinogens and co-occurring groundwater pollutants. Co-contaminants often affect the ability of microorganisms to biodegrade individual constituents. One of the mechanisms by which microbial cells overcome toxic inhibition is by transforming the inhibitory compounds. In this study, while VC inhibited DX biodegradation, it was surprisingly utilized as a growth substrate by Pseudonocardia dioxanivorans CB1190. Increasing concentrations of VC decreased DX biodegradation rates, whereas increasing DX did not have a strong effect on VC biodegradation.
Per- and polyfluoroalkyl substances (PFAS) represent a family of emerging persistent organic pollutants. Cost-effective remediation of PFAS contamination via chemical or biochemical degradation is challenging due to their extremely high stability. This study reports the removal of two representative PFAS species, perfluorooctanoic acid (PFOA) and perfluorooctanesulfonic acid (PFOS), from water by adsorption using aluminum-based water treatment residuals (Al-WTR), a non-hazardous waste generated during the process of drinking water treatment by alum salts.
In the context of climate change, which accentuates the growing scarcity of fishery resources, the traditional knowledge of West African fishermen was examined in this research.

This Article supports SDGs 3 and 6 by assessing global human water stress for low to high environmental flow protection. The findings suggest that ensuring high ecological protection would put nearly half the world's population under water stress for at least 1 month per year, meaning important trade-offs are made when allocating limited water resources between direct human needs and the environment.
Underneath the façade of supposedly bubbly girls, living daily lives in many parts of Nigeria lies the problem of lack of access to proper menstrual hygiene management tools or kits. From schools to business places, religious organizations amongst others, a hive of women and girls face the harsh reality of inability to manage their periods due to poor access to water, sanitation, and hygiene facilities, common in many low- and middle-income countries of which Nigeria sits top.

Producing clean, fresh drinking water from atmospheric water vapor can play an important role in alleviating water scarcity in drought-prone regions of the world. This perspective explores the current trends and future outlook for atmospheric water harvesting technologies.
