“…Adequate understanding of groundwater levels, flow and heterogeneous characteristics of aquifers is normally far beyond reach of non-professionals. Also in state-of-the-art science, limited knowledge hampers comprehensive source, transport and contaminant identification, even about the behaviour and prediction of well-known groundwater contaminants [4]. It is notoriously difficult to determine variations in recharge magnitudes over time and space and their relationship to climate without direct, long-term observations of groundwater levels [68].…”

“…A lack of data means that information on groundwater remains as hidden as the resource itself. Questions also remain about the behaviour and prediction of well-known groundwater pollutants and the interaction between land use categories and groundwater quality, while new concerns around emerging contaminants in drinking water bodies are on the increase [4].…”

Regarding Groundwater and Drinking Water Access through A Human Rights Lens: Self-Supply as A Norm

Globally, some 2.5 billion people depend solely on groundwater to satisfy their daily drinking water needs. The reliance on this resource and its centrality to realize the human right to ‘safe’ drinking water has increased manifold, but this is yet to be fully acknowledged globally or by governments and political leaders at the national level. This paper analyses the interface of international human rights law, as corresponding to the obligations and responsibilities of different actors, regarding groundwater resources planning, management and protection. Drawing on the literature, we discuss the State’s duties to respect, protect and fulfil this right especially in relation to the freedom of end-users to self-supply from groundwater sources; the training and regulation of non-State service providers including drillers and private vendors; and health and safety concerns. Interpreting the State’s duty to ‘fulfil’ through direct water service provision ‘as a last resort’, this paper suggests that self-provision is the original norm for enjoying the right to water. This has significant implications for the State’s role in raising awareness concerning point source protection and aquifer recharge for water resources management and in decisions concerning water allocation. By ignoring self-provision, which is primarily from groundwater, the State is not only missing a tremendous opportunity but is jeopardizing the water security of future generations.

“…Groundwater is an essential source of water for drinking, agriculture and industrial purposes in arid and semi-arid regions worldwide (Liu et al, 2010;Li, 2016). As a result of the rapid increase in population and urbanization, many environmental problems including groundwater pollution have been evolved (Burri et al, 2019;Shaharoona et al, 2019). Recently, many anthropogenic processes are responsible for groundwater contamination such as Ca, F, PO (Aiuppa et al, 2003;Redwan and Abdel Moneim, 2016a;Arslan, 2017;Burri et al, 2019) and heavy and trace metals such as Al, As, B, Ba, Fe, Co, Cd, Cr, Cu, Hg, Mo, Ni, Se, Si, V and Zn (Giammanco et al, 1998;Fu and Wang, 2011;Fu et al, 2014;Hosseini and Saremi, 2018;Kyere et al, 2018;Burri et al, 2019) .…”

Sources and health risk assessments of nitrate in groundwater, West of Tahta area, Sohag, Egypt

et al. 2020

Due to natural and anthropogenic human activities in arid and semi-arid regions, groundwater will continuously suffer from severe contaminations such as increases in nitrate levels. Groundwater contamination poses serious threats to the environment and human health. In the current study, 23 groundwater samples were collected from the desert zone around the wastewater treatment plant west of Tahta area, Sohag, Egypt. The samples were chemically and bacteriologically analyzed to quantify the sources and potential risk of nitrate in groundwater to the health of adults, children and infants. The nitrate showed wide spatial variability in the studied area, with values going from 0.38 up to 59 mg/L. Based on the bacteriological, principal component, NO 3 and NO 3-/Clanalyses, nitrate in the southwestern parts around the wastewater treatment plant developed from the sewage contamination while the northeastern and southern parts are mainly due to contamination from the agricultural activities and organic wastes. The non-carcinogenic hazard quotients (HQ) values of 78% of infants, 70% children and 4% of adults were higher than the safety level (i.e., HQs>1), suggesting severe health effects on human health. Proper management of wastewater disposal activities and application of fertilizers are required to reduce groundwater contamination in Egypt and globally.

“…As a result, it is insufficient to satisfy the consumption of water by people, which can cause economic, social and environmental impacts (Mishra and Singh, 2010). Also, anthropogenic alteration of the landscapes generate potential consequences in groundwater recharge rates, including quality and quantity of water (Burri et al, 2019). Agriculture, urbanization or industrialization impact the physical and chemical environmental processes such as water level, salinization, nutrient loads or soil degradation, affecting the ecosystem (Han et al, 2017).…”

This article analyses one of the most complex socioenvironmental conflicts in Chile: The Petorca water crisis. Petorca has been experiencing a shortage of water for several years. The cause of these variations has not yet been completely analyzed and the problem has remained unchanged. This paper evaluates hydrology variables to identify, quantify and demonstrate the cause of water shortages in the study area. Mann-Kendall and Sen's slope test statistically are applied to evaluate records of rainfall monitoring stations, water level and flow rate. To determine the existence of trends over time and quantify its magnitude. A total of 760 years of data were used by analyzing 4974 precipitation events, 788 water level and 1384 flow rate records. The results indicated that (1) There is no positive or negative trend in precipitation data over the years; (2) four well-monitoring stations have a positive trend but with an insignificant magnitude; (3) all flowmonitoring stations have a negative trend. Likewise, it was evidenced that water levels and flow rates have been affecting abruptly since 2014, obtaining null records and remain constant over time. For the same period, there is no evidence of precipitation anomalies. As a result, water resources face a host of serious threats, all of which are caused primarily by human activity. Finally, the community of Petorca is experiencing a water shortage event, which is evidenced for the first time with this scientific article.
