In-Situ Evaluation of the Filtering Function of a Piedmont Creek Swamp

摘要

A small northern piedmont region swamp in Georgia was monitored for two years, starting in September, 1976, to determine whether swamps might serve as sinks for nutrients and trace metals. Total amounts of phosphorus, nitrates, ammonia, and several trace metals flowing into and out of the Cornish Creek Swamp were monitored over the two-year period. This information, combined with chemical analysis allowed calculation of the total amount of chemical nutrients and metal passing through the swamp over the two-year study. Phosphorous, nitrogen and trace metals levels indicated the swamp waters to be pristine.
