Previous issue date: 2015-02-25 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior - CAPES / A cidade de Garanhuns-PE vem passando por uma expans?o urbana r?pida, desordenada e
poluente que tem impactado nascentes presentes no ambiente urbano as quais s?o mananciais
de relev?ncia hist?rica e ambiental para o munic?pio e para a bacia hidrogr?fica do Rio
Munda?. Diante disso, o presente trabalho teve como objetivo analisar a problem?tica
socioambiental decorrente da expans?o urbana no entorno de nascentes no munic?pio de
Garanhuns-PE. Buscando considerar din?micas sociais e ambientais, o estudo seguiu os
aportes te?ricos da geografia socioambiental, adotando o modelo te?rico-metodol?gico do
Sistema Ambiental Urbano proposto por Mendon?a (2004) e os valores conceituais da teoria
do espa?o proposta por Santos (2012a). A operacionaliza??o da an?lise envolveu pesquisa
bibliogr?fica, documental, avalia??o de impactos ambientais e an?lise da qualidade de ?gua.
Verificou-se uma grande variedade de conceitua??es e tipologias de nascentes assim como
um vasto arcabou?o legal ?til a prote??o das mesmas. Constatou-se que Garanhuns possui
singularidades ambientais favor?veis ao surgimento de nascentes e que esses mananciais
foram importantes no estabelecimento e no crescimento da cidade. Os impactos ambientais
nas nascentes Olho D??gua, Bom Pastor, Vila Maria, Pau Amarelo e Pau Pombo foram
avaliados utilizando o ?ndice de Impacto Ambiental em Nascentes ? IIAN mediante o qual se
constatou graves contextos de impactos socioambientais a din?mica das nascentes. O
Monitoramento da qualidade da ?gua superficial proveniente das nascentes Pau Pombo, Pau
Amarelo e Vila Maria foi realizado entre abril de 2013 e abril de 2014, a an?lise dos
resultados se deu com base na Resolu??o n? 357/2005 do Conselho Nacional de Meio
Ambiente, utilizando os par?metros Oxig?nio Dissolvido, Demanda Bioqu?mica de Oxig?nio,
Nitrato, Coliformes Totais, Coliformes Fecais e Condutividade El?trica. Os resultados obtidos
indicam polui??o org?nica cont?nua e profundas altera??es na qualidade das ?guas
provenientes das nascentes. Dessa forma, verifica-se que ? urgente a execu??o de medidas
visando ? interrup??o dos impactos, prote??o e conserva??o das nascentes e suas microbacias. / 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 Munda? 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 Mendon?a?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??gua, 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.
