Source, transport, and fate of nitrate in shallow groundwater in the eastern Niger Delta.

ABSTRACT: The eastern Niger Delta region in Nigeria is a hotspot for reactive nitrogen pollution due to extensive animal husbandry, pit latrine usage, and agricultural practices. Despite the high level of human activity, the sources and processes affecting nitrogen in groundwater remain understudied. Groundwater nitrate (NO₃^-) concentrations are highly variable, with some areas recording values well above the safe drinking water threshold of 50 mg/L. This is particularly true near municipal sewage systems. Elevated nitrite (NO₂^-) and ammonium (NH₄⁺) concentrations were also detected in the study area. Sewage analysis revealed NO₃^- concentrations ranging from 1 to 145 mg/L, NO₂^- from 0.2 to 2
