Avaliação macroscópicas das nascentes da região norte do município de Cocal - PI

Abstract

Water is extremely important for the existence of all living beings on the surface, however, over the decades it has suffered a series of degradations and damage, mostly caused by human action, damaging its maintenance on the planet. The research aims to map and evaluate the environmental impacts of springs in the municipality of Cocal, based on macroscopic analysis, seeking to classify the degree of preservation, identify the main agents of degradation and possible mitigating actions to be taken. The methodology used was the use of the parameters of the MAI (macroscopic environmental index), visual identification of the springs, scoring them and classifying their degree of preservation. With the macroscopic environmental index and classes of the springs defined it was possible to observe that 8 (66.66%) of the studied springs were classified as class E, considered as very poor. While 2 (16.66 %) springs are in class B, being of good preservation degree and 2 springs as C and D, being diagnosed with reasonable and bad. The lack of protection, undue amount of solid waste, and contamination of the water by animals and humans are the main negative points that influence the degradation of the springs studied
