A new paper by Adrian Seeholzer and co-authors has been published in the journal Water Research.
Nitrate concentrations in groundwater frequently exceed the EU drinking water limit of 50 mgL⁻¹, threatening drinking water quality. This study evaluates a novel in situ nitrate removal strategy based on methane injection to stimulate autochthonous denitrifiers. Methane was injected into a meso‑scale artificial aquifer equipped with horizontal injection wells and a comprehensive monitoring system. We hypothesized that methane injection promotes methanotrophic denitrification and enhances microbial nitrate removal in groundwater.
