The conservation of the watercourses are essential because they
enable the accomplishment of activities that need this natural resource and
determine the characteristics of the microbasin in which they are inserted.
Rapid population growth requires increased use of natural resources, such as
water in streams. In addition to the use, incorrect treatment and
environmental impacts are increasingly decreasing the water availability of
rivers and tributaries in each river basin. The microcatchment of the Cascata
stream and / or Tabuinha shows signs of environmental degradation, since the
depth and quantity of water in the stream is scarce. In this context, the
objective of this study was to analyze parameters that determine the water
quality of the stream, as well as to analyze the interference of a tannery.
