Groundwater constitutes the largest reservoir of liquid freshwater in the world (75% of the European population depends on groundwater). Nonetheless, the extensive use of fertilisers and pesticides in agricultural and farming activities has resulted in the nitrate pollution of aquifers, leading to the degradation of the groundwater quality, which limits its potential use as a supply.
In this context, Nirvana will develop an innovative, effective and sustainable technology for in situ remediation of nitrate polluted aquifers. Specifically, zerovalent iron nanoparticles (nZVI) will be injected into the aquifer in order to convert pesticides into more biodegradable compounds and enhance biological denitrification in the aquifer.
