Nitrate contamination and source apportionment in surface and groundwater in Ghana using dual isotopes (15N and 18O-NO3) and a Bayesian isotope mixing model
The rising food production to meet the growing human population has led to increased
anthropogenic inputs of nutrients such as NO 3− in groundwater and aquatic environments.
Nitrate concentrations, hydrochemistry, and isotope data (δ 18 OH 2 O, δ 2 H–H 2 O, 15 N–
NO 3, and δ 18 O–NO 3) from boreholes (BH), hand dug wells (HDW), and surface water
(SW) were analyzed. The objectives of the study were to identify potential nitrate sources
and their proportional contributions using an isotope mixing model (SIAR). The results …
