World Water Day 2022

World Water Day is on 22 March every year. It is an annual United Nations Observance, started in 1993, that celebrates water and raises awareness of the 2 billion people currently living without access to safe water. A core focus of World Water Day is to inspire action towards Sustainable Development Goal (SDG) 6: water and sanitation for all by 2030.

This year’s theme is ‘groundwater’ and draws attention to the hidden water resource that has always been critically important but not fully recognized in sustainable development policymaking. Groundwater is invisible, but its impact is visible everywhere. Out of sight, under our feet, groundwater is a hidden treasure that enriches our lives. Almost all of the liquid freshwater in the world is groundwater. As climate change gets worse, groundwater will become more and more critical.  We need to work together to sustainably manage this precious resource. Groundwater may be out of sight, but it must not be out of mind. 

To raise awareness on sustaining groundwater, Elsevier presents a curated list of publicly available journal articles and book chapters. At Elsevier, we are advancing #SDG6 research and ensuring that #groundwater is sustainably explored, analyzed, and monitored.


Clean Energy and Resources Recovery. Biomass Waste Based Biorefineries, Volume 1, 2021, Pages 145-154

This chapter advances SDGs 6 & 7 by discussing how to convert gelatinous industry wastewater into useful chemicals and fuels.

Clean Energy and Resource Recovery. Wastewater Treatment Plants as Biorefineries, Volume 2, 2022, Pages 301-314

This chapter advances SDGs 6 & 7 by examining the potential for wastewater to be converted into a renewable fossil-fuel alternative.

Clean Energy and Resource Recovery. Wastewater Treatment Plants as Biorefineries, Volume 2, 2022, Pages 17-36

This chapter advances SDGs 6 & 7 by critically examining the recent developments, opportunities, market possibilities, and barriers in resource recovery in wastewater treatment plants.

Handbook of Algal Biofuels. Aspects of Cultivation, Conversion, and Biorefinery, 2022, Pages 167-179

This chapter advances SDGs 6 & 7 by describing the use of halophilic algae for the desalination of seawater for drinking and other uses.

Transportation Research Part D: Transport and Environment, Volume 102, January 2022

This paper cautions that the adoption of electric vehicles with the aim of reducing greenhouse gas emissions must balance that beneficial effect against increased water consumption. It recommends battery electric vehicles charged by solar energy as the best solution.

Materials Today Sustainability, Volume 10, December 2020

Iodide and bromide ions in surface and ground waters can react with natural organic matters and produce toxic disinfectant by-products. A novel bismuth composite material has been developed for the removal of iodides and bromides at parts per million concentrations.

Journal of Contaminant Hydrology, Volume 243, December 2021

Polycyclic aromatic hydrocarbons (PAHs) in water pose a serious threat to human health due to their toxic effects. This manuscript evaluates various drinking water treatment processes to remove these compounds from drinking water, in order to assure the quality of water intended for human consumption.

Progress in Disaster Science, Volume 8, December 2020

This paper examines the global trends and main health impacts of these events based on databases and case studies, identifies gaps in the Sustainable Development Goals (SDGs) indicator framework for monitoring health impacts of disasters and suggests recommendations to address these gaps.
