Pathogen contamination of groundwater systems and health risks

Critical Reviews in Environmental Science and Technology, Год журнала: 2023, Номер 54(4), С. 267 - 289

Опубликована: Июль 22, 2023

Groundwater has been a relatively safe water source and associated with series of global pressing issues. It can, however, be vulnerable to pathogen contamination exhibit risks public health. While groundwater often considered closed ecosystem, it is important understand the transport pathogens into within groundwater-dependent ecosystems in context their physiological characteristics, soil/sediment texture, hydrogeological climatic conditions. The rapid progress monitoring modeling tools recent years facilitated detection prediction migration groundwater, which aids surveillance remediation health-related risks. This review aims provide an updated understanding about pathogens, impacts on human health, surveillance, risk assessment, strategies environment climate changes. challenges perspectives protecting biosafety are also discussed.

Spatial variations in groundwater hydrochemistry, sources, and controls across catchments on Chinese Loess Plateau

Journal of Hydrology Regional Studies, Год журнала: 2024, Номер 53, С. 101791 - 101791

Опубликована: Апрель 26, 2024

This study was carried out at the Chinese Loess Plateau (CLP), which is located in middle reach of Yellow River northern China. Understanding groundwater hydrochemistry and its controlling factors regions like CLP with thick unsaturated zones challenging due to limited accessibility. The primary objective this investigate hydrochemistry, sources, controls, assess suitability for drinking irrigation purposes across 14 major catchments CLP. Our results showed that composition dissolved solutes primarily influenced by weathering rock, particularly silicate rock. However, human activities, especially agriculture urban areas, also have a notable impact on solutes. presence elevated nitrate various underscores urgency addressing long-term nitrogen pollution. Environmental changes such as climate change, erosion rates, land-use patterns are key shaping quality. As air temperature decreases intensifies, along more intensive land use, ion concentrations tend rise. Note that, approximately 91% suitable direct drinking, but ensuring proper drainage crucial prevent sodium damage during irrigation. These findings enhance our understanding influencing essential effectively managing quality

Aquifers and Groundwater: Challenges and Opportunities in Water Resource Management in Colombia

Water, Год журнала: 2024, Номер 16(5), С. 685 - 685

Опубликована: Фев. 26, 2024

Water is essential for life on Earth, playing fundamental roles in climate regulation, ecosystem maintenance, and domestic, agricultural, industrial processes. A total of 70% the planet covered by water. However, only 2.5% fresh water, much it inaccessible. Groundwater main source planet’s available water resources. For that reason, groundwater a critically important resource, increasingly vulnerable due to crisis contamination. These challenges threaten availability clean safe necessitating an understanding effective sustainable management. This review presents overview concepts aquifers groundwater. Also, reflects importance these resources developing countries such as Colombia (South America). In addition, considers characteristics mineral waters, their uses, associated risks, well exploration control policies. country with immense biological wealth crucial maintaining global Nevertheless, managing Colombia’s challenge, many have not yet been fully explored. order achieve this, necessary study hydrogeochemistry through application advanced technologies analyze dynamics, distribution, quality groundwater, its vulnerability pollution change.

Enrichment of Geogenic Organoiodine Compounds in Alluvial-Lacustrine Aquifers: Molecular Constraints by Organic Matter

Environmental Science & Technology, Год журнала: 2024, Номер 58(13), С. 5932 - 5941

Опубликована: Март 19, 2024

Organoiodine compounds (OICs) are the dominant iodine species in groundwater systems. However, molecular mechanisms underlying geochemical formation of geogenic OICs-contaminated remain unclear. Based upon multitarget field monitoring combination with ultrahigh-resolution characterization organic components for alluvial-lacustrine aquifers, we identified a total 939 OICs under reducing and circumneutral pH conditions. In comparison to those water-soluble matter (WSOM) sediments, dissolved (DOM) typically contain fewer polycyclic aromatics polyphenol but more highly unsaturated compounds. Consequently, there were two major sources groundwater: migration from aquifer sediments abiotic reduction iodate coupled DOM iodination occurs primarily through incorporation reactive that is generated by into compounds, preferably containing hydrophilic functional groups as binding sites. It leads elevation concentration up 183 μg/L groundwater. This research provides new insights constraints composition on mobilization enrichment aquifers thus improves our understanding genesis iodine-contaminated
