“…The PRB was successful in removing nitrate at inlet concentrations up to 280 mg/L from groundwater (with nitrate removal percentages of approximately 97%). Groundwater monitoring at various depths within the PRB provided evidence that nitrate preferably underwent denitrification at the deepest part of the PRB, where more favorable reducing conditions were achieved (Gibert, Assal, Devlin, Elliot, & Kalin, 2019).…”

Groundwater pollution is a result of natural and anthropogenic activities. While the elevated levels of various inorganic constituents could be attributed to natural processes, such as geological weathering and aquifer characteristics, many times, anthropogenic activities also substantially pollute the groundwater. On the contrary, the occurrence of organic pollutants is primarily due to various anthropogenic activities. Extensive groundwater mining, the hydraulic connection between groundwater and other surface water bodies, and leaking underground buried infrastructure also contribute to groundwater pollution. Water resources are scarce commodities, and preserving groundwater quality is of critical concern. This paper documents instances of groundwater quality impact during the year 2019 due to both natural and anthropogenic activities throughout the world.

“…Hence, active system requires regular maintenance, and due to continuous addition of reagent operations like mixing, separation and pumping are also required (Gruiz, 2019). Gibert et al (2019) reported that field-scale permeable reactive barrier for the biological treatment of nitrate-contaminated groundwater was able to remove nitrate up to 97%, where a mixture of gravel and mulch was used as reactive materials and served as a carbon source for denitrifying bacteria. Gholami et al (2019) investigated the biodegradation of toluene and naphthalene from groundwater and showed promising results by using encapsulated magnesium peroxide nanoparticle in the permeable reactive barrier for 50 days, and the impact of microorganisms on the groundwater treatment was notable in comparative study of biotic and abiotic contaminant remediation.…”

Groundwater is a vital component of water supply for residential, industrial, and agricultural purposes. However, many groundwater basins are being used unsustainably and groundwater contamination is a growing water quality problem. Although anthropogenic activities and natural processes have been increasing the contamination in this valuable water resource, several remediation techniques have been developed in the last few decades to reduce these contamination levels. This review paper focuses on the recent studies developed on groundwater pollutions, remediation practices, and groundwater quality management.

“…Restando in nord America, in Canada ci sono esempi di BRP per la rimozione di metalli pesanti 3 . In Europa va segnalata la prima BRP europea per la rimozione di nitrati da acque sotterranee 4 . Non mancano installazioni in parti del mondo dove sussistono condizioni "estreme" come la BRP per la rimozione di metalli pesanti e idrocarburi, presso la Casey Station, in Antartide 5 .…”

L'inquinamento, provocato da attività agricole e industriali, può causare la contaminazione delle matrici ambientali, costituendo un rischio significativo per l'approvvigionamento di acqua potabile e per gli ecosistemi. Pertanto, negli Stati Uniti e in Europa si sono sviluppate, nel corso degli anni, diverse tecniche di bonifica. In particolare, per il risanamento di acque sotterranee, un metodo in situ relativamente nuovo e potenzialmente importanteè la barriera reattiva permeabile (BRP). Essa prevede la realizzazione di una barriera all'interno della zona satura del terreno con materiali reattivi per il trattamento di contaminanti organici e inorganici presenti in forma disciolta nell'acqua di falda. L'articolo illustra il funzionamento delle BRP attraverso l'esposizione di un caso studio, dove tale tecnologia ha permesso di ridurre le concentrazioni di uranio nelle acque sotterranee di un sito di stoccaggio.
