Comparison of Drainage Basin Nutrient Inputs with Instream Nutrient Loads forSeven Rivers in Georgia and Florida, 1986-90

摘要

Instream nutrient loads of the Altamaha, Suwannee, St. Johns, Satilla, Ogeechee,Withlacoochee, and Ochlockonee River basins were computed and compared with nutrient inputs for each basin for the period 1986-90. Nutrient constituents that were considered included nitrate, ammonia, organic nitrogen, and total phosphorus. Sources of nutrients considered for this analysis included atmospheric deposition, fertilizer, animal waste, wastewater-treatment plant discharge, and septic discharge.
