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 chapter examines how PPCPs are often termed as micropollutants or trace organics, as these compounds are present in the µg/L range in the environment. PPCPs may pose a serious threat to aquatic life, having acute and chronic toxicity responses. As a result, there is a need for evolving technologies to detect, identify, and remediate compounds from these micropollutants.
This chapter advances SDGs 6 & 7 by critically examining the recent developments, opportunities, market possibilities, and barriers in resource recovery in wastewater treatment plants.
This chapter advances SDGs 6 & 7 by presenting membrane technologies that can be used to purify wastewater and produce biomass for energy.

Pesticides have the potential to contaminate groundwater resources and have become a serious concern worldwide. In this chapter, we have discussed the mechanism of pesticide pollution along with its trajectory from the land surface into aquifers. Additionally, the harmful effects of pesticides on human health and promising remedies for reducing pesticide pollution have also been discussed.
Even though a significant improvement in growth and nutrition was not noted among the integrated interventions, the importance of water, sanitation, and hygiene (WASH) and addressing it in reducing undernutrition is of the utmost importance
Responsive small-molecule fluorescence probe specific for target analyte detection is an emerging technology for food safety and quality analysis. In this work, we report a new water soluble small-molecule fluorescence probe (PG) for the detection of hypochlorous acid (HOCl) in drinking water samples. Probe PG was developed by coupling of a glucosamine into 10-methyl-10H-phenothiazine fluorophore with a HOCl-responsive C=N bond. The thioether is another recognition site that can be oxidized to be sulfoxide in water.
Anemia affects more than half of Nepalese children aged 6–59 months. Although prevalence varies year to year, the stability of observed risk factors suggests the need to focus on reducing gastrointestinal infection, promoting adequate household sanitation, and improving maternal and child health.
The identified thematic gaps in Kenyan school books, particularly regarding sanitation, hygiene, and menstrual hygiene education, align with global WASH priorities and require urgent attention, especially in light of COVID-19. Addressing disconnects between educational content, WASH interventions, policies, and implementation highlights the necessity for improved integration to foster sustainable behavior change, emphasizing the importance of leveraging local educational materials and knowledge to engage teachers and school managers effectively and enhance WASH practices in schools.

The widespread consumption of electronic devices has made spent batteries an ongoing economic and ecological concern with a compound annual growth rate of up to 8% during 2018, and expected to reach between 18% and 30% to 2030. There is a lack of regulations for the proper storage and management of waste streams that enables their accumulation in open settings and the leakage of hazardous substances into the environment on landfill settings.
