This in situ remediation technique involves the interception of groundwater flow to remove contaminants by physical, chemical or biological processes. In the case of nitrate pollution, heterotrophic or autotrophic denitrification can be induced by using organic or inorganic substrates, respectively. On the other hand, several PRB filled with Zero-Valent Iron (ZVI) have been installed to remediate groundwater polluted with chlorinated solvents (Wilkin et al., 2014) or nitrate (Gu et al., 2002).2 p.application/pdfeng(c) Grau Martínez, Alba et al., 2014GeoquímicaDesnitrificacióGeochemistryDenitrificationinfo:eu-repo/semantics/article6736882023-02-06info:eu-repo/semantics/openAccess
