Abstract: Impact of irrigation trend, water table fluctuations, crop management, and tillage systems on groundwater quantity and quality of the southeast (Alabama, Florida, Georgia, and South Carolina) and Delta states (Arkansas, Louisiana, and Mississippi) are discussed. Areas with specific groundwater quality problems such as salt water intrusion and nitrate and pesticide levels are identified. Degradation of surface water quality is discussed relative to irrigation. The discussions provide the basis for developing irrigation and management systems to minimize groundwater withdrawal and surface and groundwater contamination by agricultural chemicals.
