The influence of nitrate leaching through unsaturated soil on groundwater pollution in an agricultural area of the Basque country: a case study [PDF]

, 2003
The average nitrate concentration in the groundwater of the Vitoria-Gasteiz (Basque Country) quaternary aquifer rose from 50 mg NO3−/l during 1986 to over 200 mg/l in 1995, which represents an increase of some 20 mg NO3−/l per year.
