One of the main causes of pollution of the different bodies of water is the amount of nutrients and organic matter (OM) which are discharged as a result of various human activities; excessive enrichment of water, primarily nitrogen (N) and phosphorus (P), generates a deterioration of water resources and aquatic ecosystems generally due to the involvement of the physico-chemical and microbiological quality of water. In this research the results of the evaluation of two species of emergent plants native Scirpus californicus and Typha angustifolia of the study area used for the removal of organic matter in artificial wetlands systems is presented.
