Resumen
Garanhuns City, in Pernambuco, undergoes a rapid, polluting and non-organized urban
development affecting its freshwater springs around the urban environment. These sources are
of great importance to the district as well as to the hydrographic basin of the Mundaú River.
In this view, this paper aims at analyzing the socio-environmental problems resulting from the
urban expansion surrounding the Garanhuns’ sources. The study considers the social and
environmental dynamics and follows the theoretical contributions of socio-environmental
geography proposed by Mendonça’s Urban Environmental System methodological and
theoretical model (2004), as well as the conceptual values of Santos’ space theory (2002a).
The data treatment included bibliographical and documental research, evaluation of
environmental impact, and water analysis. It revealed that Garanhuns possesses many local
environmental traits favoring the coming out of freshwater springs and that these sources have
played an important role in the making and development of that village. The environmental
impacts on freshwater springs, like Olho D’água, Bom Pastor, Vila Maria, Pau Amarelo and
Pau Pombo have been evaluated through the environmental impact score IIAN. It put alight
serious cases of socio-environmental impacts on the dynamics of the freshwater springs. In
the period of April 2013 and April 2014, it monitored the superficial water quality expelled by
the Pau Pombo, Pau Amarelo e Vila Maria water sources, and the analyses of the contents
followed the determinations of the Environmental National Board, whose parameters are
dissolved oxygen, biochemical demand of oxygen, nitrate, total coliforms, faecal coliforms,
and electrical conductivity. The results recollected suggest the existence of organic pollution
and deep alteration in the water coming out from the sources. In consequence, it seems
important the putting out of measures destined to stop those impacts and guaranteeing
protection and maintenance of the freshwater springs and their micro-basins.
