Importância da mata ciliar (ripária) na qualidade da água de abastecimento do Rio Piava no ponto de captação de Umuarama – PR

Abstract

Water being a natural resource indispensable to life and that Mata riparian exerts influence on the quality of the water bodies, the present work aimed to assess influence of the ciliary forest in the quality of the water in the river Piava located in the municipality of Umuarama-PR, Compared with the current legislation 12.651/2012 and CONAMA 357/2005, where analyses carried out by the Sanepar were evaluated at the point of capture and water samples were collected in a two-month interval in dry and rain period, forwarded to the laboratories Fertile soil and UEM, where physical-chemical analyses were carried out such as, total dissolved solids, turbidity, PH, color and microbiological as, Escherichia coli, according to the methodology constant in Standard methods, following the parameters required by Legislation in force. After obtaining the results, he confronted with the legislation, concluding that the riparian forest of the Piava River partially falls under the law 12.651/2012, and studies for the recovery of the degraded sites are needed. The water body was also partially framed in resolution 357/2005 as Class III, due to the lack of data in Sanepar analyses. There was no significant difference between periods of drought and rain in the points with preserved forest and partial Mata, except for the color parameter which presented a higher average in the dry period and in points with partial ciliary forest.
