Quality of 20 shallow ground watersin an intensively farmed area of Chai-nan Plain that imports high qualitysurface water during rice cropping se-ason was surveyed and studied. Someof the ground waters have shown a hi-gh nitrate or ammonium contamination.Problems of pollution of the waterswhen nitrate and ammonium being aspollutants were basically discussed inrelation to fertilizer level, fertilizingtime, soil properties and farm irrigationwhich were considered as some factorsto affect the degree of water pollution. Nitrate leaching has, for a longtime, been recognized as one of mainprocesses to contribute ground watercontamintion of nitrogen in previousliterature. In the flooding conditionof paddy field, the leaching of ammo-nium with the downward movementof gravitational water from a fertilizedsoil can be anther process which hasbeen found in this study.
