The aims of this investigation was to create an updated view of the nitrate distribution for the country, to identify whether there are any gaps or significant changes in the distribution of nitrate concentration over the sampling record and identify areas where nitrate pollution occurs as an ecological hazard for priority research and remediation. Data was sourced from the national groundwater database for the entire country for the period up until 2008. Keywords: Nitrate concentrations, Groundwater content, Groundwater database, Spatial analysis, Temporal analysis, Hydrology.
