Aplicação de protocolo de avaliação rápida para análise de nascentes na área urbana de Araruna - Paraná

Abstract

Rapid Assessment Protocols (RAPs) are methods used to conduct environmental assessments, primarily in aquatic ecosystems, bringing together procedures adapted to the rapid, qualitative and semi-quantitative evaluation of a set of variables, representing components and factors that can determine the water quality of a spring, river or stream. This study addresses the evaluation of environmental impacts on the springs in the municipality of Araruna (PR), in order to analyze the degree of interference suffered. Seven springs located in the Ívai River Basin were studied. Site visits were conducted to observe the state of the springs and evaluate various macroscopic parameters. In these parameters, most of the springs were found to be degraded, mainly due to: litter in the surrounding area, use by animals and humans, proximity to residences, and lack of adequate or efficient protection. The detected impacts on the springs occur primarily because they lack any type of protection and are very close to residences.
