“…Similarly, studies about groundwater pollution have revealed contamination with polycyclic aromatic hydrocarbons, fuel hydrocarbons, chlorinated ethylenes, and nonchlorinated solvents . The existing technologies to remediate groundwater (e.g., pump and treat, oxidation, biodegradation, and adsorption) are expensive and inefficient . This lack of efficient technologies to remediate remote polluted water increases the demand for new materials and efficient technologies.…”

An approach for underground, deep, and turbid water remediation is presented based on optical fibers with a photocatalytic coating. Thus, photocatalytic TiO 2 P25 nanoparticles immobilized in a poly(vinylidene difluoride) (PVDF) matrix are coated on polymeric optical fibers (POFs) and the photocatalytic performance of the system is assessed under artificial sunlight. To the best of our knowledge, poly(methyl methacrylate)‐POF coated with TiO 2 /PVDF and the reusability of any type of POF for photocatalytic applications are not previously reported. The photocatalytic efficiency of the hybrid material in the degradation of ciprofloxacin (CIP) and its reusability are evaluated here. It is shown that 50 w/w% of TiO 2 P25 achieves a degradation of 95% after 72 h under artificial sunlight and a reusability of three times leads to a loss of activity inferior to 11%. The efficient removal of ciprofloxacin and the stability of the POF coated with TiO 2 P25 successfully demonstrate its suitability in the degradation of pollutants with potential application in regions with low light illumination, as in underground and deep water.

“…About 33% of the human population, globally, uses groundwater as drinking sources [1][2][3][4][5]. However, groundwater quality may be altered by several anthropogenic sources, such as waste disposed of by faulty practices, industrial pollution, unplanned urbanization, correlated with natural geogenic processes [6][7][8][9]. Groundwater assessment is important for identifying possible sources of contamination and assessing these contaminants to properly use this groundwater [10,11].…”

This study investigated the spatial and temporal distribution of nitrate and nitrite concentration in groundwater from different geographical regions, in Romania. A special emphasis was put on a descriptive statistical analysis of data, namely on the determination of seasonal indices during dry and wet seasons. Nitrate and nitrite concentrations were monitored in 24 groundwater sources situated in different areas, between January 2016 and February 2020. The obtained data showed that the values of nitrate concentrations were situated between 8.03 mg/L in the North-Eastern part of Romania, 6.37 mg/L in the South-Eastern part of the country, and 3.55 mg/L in the Western part towards the center of the country. Nitrite concentration values were situated under the national maximum admitted limit, 0.5 mg/L, in all the investigated areas. The obtained data shows small changes in water quality during the monitoring period, which leads to the conclusion that, in this long interval of time, there were no significant groundwater contaminations with nitrate and nitrite. For adequate control of water pollution and rigorous management of groundwater sources, seasonal indices were calculated.

“…However, its quality can be modified by numerous anthropogenic sources such as faulty waste disposal practices, unplanned urbanization, industrial pollution, etc. besides natural geogenic processes (Manorama and Paulsamy 2013;Jhariya et al 2017;Swartjes and Otte 2017;Selvakumar et al 2017). The groundwater chemistry is governed not only by the geomorphology, soil type and residence time but also by the atmosphere, soil and weathering of rocks as well as other anthropogenic sources like mining, unplanned urbanization and industrialization (Prasanth et al 2012;Singh et al 2015;Srivastava 2007).…”

Physicochemical characteristics of groundwater provide vital information regarding prevailing geochemical, geomorphological and predominant pollution conditions in an area. In the present work, hydro-geochemical properties of ground water were examined at rural, urban and industrial areas of Kanpur to determine its aptness for drinking and irrigation. Groundwater samples were randomly collected from deep borewell pumps across the city. The samples were examined for pH, electrical conductivity (EC), nitrate, sulphate, chloride, hardness, alkalinity, total dissolved solids, sodium, potassium, calcium, which ranged between 7.10 and 8. −1 in post-monsoon season respectively. Water Quality Index of groundwater during post-monsoon were recorded to be better than the pre-monsoon season, reason being percolation of water during rainfall in monsoon. The pre and post-monsoon data provided valuable information regarding the suitability of groundwater for various purposes such as drinking and irrigation. Results showed 'fairly' and 'good' categories of water quality in the pre-monsoon season which further improved in post monsoon season. Results clearly specify that the natural process of groundwater recharge is an important mechanism to maintain the quality of groundwater.
