Surface Water

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.
Water and wastewater utilities, water and sanitation hygiene (WASH) practitioners, and regulating bodies, particularly in developing nations, rely heavily on indicator microorganisms, as opposed to pathogens, for much of their regulatory decisions. This commentary illustrates the importance of considering pathogens and not relying only on indicator organisms when making decisions regarding water and sanitation, especially with respect to meeting the current targets of the Sustainable Development Goal (SDG) 6.
Recent policy developments in Europe consider the importance of water ecosystems to human wellbeing and the detrimental effects that multiple pressures may have on them. Several directives and measures which culminated with the design and the implementation of the Water Framework Directive, have attempted to address the issue of sustainable water management while aligning with targets of economic development.
This study supports SDGs 3 and 6 by analysing data from 88 low-income and middle-income countries and showing geographical disparities in access to clean water and sanitation facilities. These findings identify where efforts to increase access to safe water and sanitation have been successful over time, and highlight the need for targeted and tailored interventions to reach those communities and regions that have been left behind.

Plastics are a frequently observed component of marine debris and there is growing concern about microplastic (MP) ecotoxicity, and the impacts of additives, sorbed hazardous organic contaminants, heavy metals, and biofilm on MP surfaces. The relative importance of MP from different terrestrial and freshwater sources is poorly understood and limits our ability to develop best management practices. This review focuses on evidence and methods for source apportionment of MP in freshwater environments including the use of MP characteristics, mass balance techniques, and surface characteristics.
Water resources are an essential and determining factor for food production, ecosystem health, and socio-economic development. The socio–economic water cycling system is a complex adaptive system. Changes in the socio-economic system at the macro level, such as industrial transformation, technical progress, and water price reform, will have impacts on water resources utilization at the micro level.
