“…For this method, one or more extraction wells are used to remove contaminated water and are pumped from the subsoil for the treatment operation, which may consist of air removal, carbon adsorption, or a biological treatment system (Brusseau 2019). When applied to saturated subsurface systems, such as aquifers, the pump and treat method promotes in situ techniques for contaminant removal (Freire et al 2014).…”

“…In addition to costs, physicochemical remediation techniques influence soil properties, such as fertility and biodiversity. However, techniques such as phytoremediation are economically viable, environmentally correct, and sustainable for large-scale application (Freire et al 2014;Khalid et al 2017;Liu et al 2018;Yu et al 2020).…”

The contamination of soils and groundwater has attracted worldwide attention, since many contaminants are poorly biodegradable and can accumulate in living organisms, causing implications for plants, animals, and human health. The high cost of conventional remediation processes stimulates research for the development of innovative and more sustainable techniques. Likewise, phytoremediation is a cheap technology that uses plants to absorb, transform, and detoxify contaminants through in situ (phytoextraction, phytotransformation, and phytovolatilization) and ex situ mechanisms (phytostabilization and phytostimulation). Recently, phytoremediation has been adopted as a more profitable technique than physicochemical processes. Otherwise, the existence of variables, such as interactions between climate, soil, and plants, requires analysis methods for its implementation, which ensure the reduction of time and cost and improve its efficiency. Research on the application of different phytoremediation techniques is still in progress, and therefore, this study evaluated the main advantages of phytoremediation through a literature overview, comparing the most adequate remediation models in terms of economic, social, and environmental aspects. Highlighted Conclusions1. Phytoremediation consists of the use of plants and their associated microbes for environmental cleanup and recovery of contaminate soil. 2. Phytoremediation promotes social-economics benefits comparing to the conventional techniques, and ensures sustainability in environmental rehabilitation.

As águas subterrâneas são largamente utilizadas para diversas atividades em todo o mundo, no entanto, este recurso natural está sendo silenciosamente contaminado por atividades antrópicas, dentre elas, a comercialização de combustíveis oriundos de petróleo. O objetivo desta pesquisa foi avaliar a redução da contaminação por combustíveis, utilizando a técnica de Extração Multifásica. O sistema atuou por 32 meses, extraindo um total de 350,43 m³ de água subterrânea contaminada. Alguns poços de extração, apresentaram concentrações acima do limite estabelecido pela análise de risco, no entanto, isto se deve a constante drenagem de contaminantes. Os resultados apresentados demonstraram uma redução nas concentrações de BTEX, variando entre 3,9 a 98,2% em 60% dos poços que apresentaram contaminação, e os compostos dos PAH, indicaram uma redução de 78,2 a 100% das concentrações na água subterrânea em 80% dos poços de extração e monitoramento. Contudo, houveram indícios de contaminação persistente no solo, deste modo, seria ideal a aplicação de uma segunda técnica de remediação para a remoção da contaminação de fase adsorvida no solo e assim, evitar o retorno de contaminantes.
