Fig. 3. Nitrogen leakage into groundwater from rainfall, fertilizer use, irrigation with
nitrate-containing groundwater and wastewater, seepage from waste dumps and fish ponds,
and discharge of domestic wastewater disposal. (Nitrogen leakages in the eastern WRA are
incomplete due to partially missing data). The nitrogen leakages indicate the importance of
agriculture as well as the importance of human settlements without wastewater treatment
(notably over the Cenomanian recharge area, see Fig. 1)
