Nitrate attenuation with rising groundwater levels: An integrated assessment using isotope tracers and microbial signatures

•Nitrate attenuation in aquifers undergoing groundwater-level recovery was first revealed.•An integrated assessment using isotope tracers and microbial signatures was employed.•A larger temporal enrichment factor (ε) value was found at − 25‰. Nitrate contamination of groundwater has long been a sour...
