Many studies have indicated that the nitrogen concentration is negatively correlated with the well depth (Majumder, Hasnat, Hossain, Ikeue, & Machida, 2008; Squillace et al., 2002; Townsend & Young, 2000) because the pollutants from human activities do not leach into the much deeper and confined aquifer (Bonton, Rouleau, Bouchard, & Rodriguez, 2010; Masetti, Poli, Sterlacchini, Beretta, & Facchi, 2008).
