Interpretive Summary: Non-point source water pollutants resulting from agricultural areas have been implicated as a source of water quality degradation in South Florida, USA. The nutrients loading from agricultural and urban areas have incrased nutrient concentrations, particularly phosphorus, at the Everglades National Park (ENP), Florida. The results indicated that during the summer season (wet season) the quality of water in the agriculture area is correleated with the water quality in the canal. However, during the winter season (dry season) there is correlation between the nutrient content of the wells located in the agriculture area and the nutrient content of the main canal. In South Florida, the growing season and the application time of agro-chemicals for most vegetables is during the winter; therefore, the source of observed nutrients in the main canal should not be from the agricultural area in South Florida.

Technical Abstract: Non-point source water pollutants resulting from agricultural areas have been implicated as a source of water quality degradation in south Florida, USA. The nutrients loading from agricultural and urban areas have increased nutrient concentrations, particularly phosphorus, at the Everglades Natinal Park (ENP), Florida. Ground water table fluctuation and quality have been monitored for three years in a one-mile transect. In addition, water quality of the main canal located at the end of the transect has been monitored on a weekly basis. The result indicated that during the summer season (wet season) the quality of water in the agriculture area is hugely correlated with the water quality in the canal. However, during the winter season (dry season) there is no correlation between the nutrients content of the main canal. In addition, the quality of ground water in natural area near the ENP was not affected by construction of new water retention.
