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.

Previous issue date: 2016-02-04 / O crescimento desordenado da capital potiguar ocorrido a partir da d?cada de 1970 ocasionou s?rios problemas ambientais urbanos. Nesse contexto de r?pido incremento populacional, a constitui??o do Lix?o de Cidade Nova ampliou a problem?tica socioambiental por via da emiss?o elevada de chorume no solo culminando na contamina??o do len?ol fre?tico, o que trouxe s?rios problemas para a qualidade do abastecimento h?drico da popula??o. Desta forma, a presente pesquisa busca analisar a rela??o entre a contamina??o gerada pela deposi??o dos res?duos s?lidos no Lix?o de Cidade Nova por mais de tr?s d?cadas e o prec?rio esgotamento sanit?rio implantado nos bairros de Felipe Camar?o, Planalto e Guarapes. Foi feito levantamento bibliogr?fico para a discuss?o sobre esta rela??o entre urbaniza??o, problem?tica socioambiental e contamina??o de ?guas subterr?neas. Al?m disso, foi feito tamb?m um levantamento sobre a estrutura f?sica da ?rea de estudo, assim como das legisla??es relativas ? tem?tica. Ainda no plano metodol?gico, foi feita pesquisa de campo nos po?os destinados ao abastecimento h?drico P1 e P5 no bairro de Felipe Camar?o e P2 no bairro do Planalto no per?odo de maio de 2014 a maio de 2015. Os resultados da pesquisa demonstram que h? contamina??o das ?guas destinadas ao abastecimento humano nos referidos bairros, e que esta adv?m da inadequada deposi??o de res?duos s?lidos no solo, assim como da aus?ncia de um adequado esgotamento sanit?rio. A pesquisa apresenta como conclus?o a constata??o de latente necessidade de pol?ticas p?blicas que atenuem tais problemas no contexto socioambiental da ?rea estudada. / The uncontrolled growth of Natal occurred at the 1970s caused serious urban environmental problems. In this context, the establishment of the ?Cidade Nova? trash dump has expanded social and environmental problems by the high emission of contaminant itens on the soil, resulting in contamination of the water table, which brought serious problems for the quality of the water supply. This research aims to relate the pollution caused by the deposition of solid waste in ?Cidade Nova? trash dump for more than three decades and the precarious sanitation deployed in the districts of Felipe Camar?o, Planalto and Guarapes, with the consequent contamination of the wells of respective districts for human consumption. For this purpose, the literature was researched to the discussion about the relationship between urbanization, environmental issues and contamination of groundwater. Furthermore, was made a research about the physical structure of the study area, even as about the laws on the subject. About the methodology, a massive fieldwork was done in the wells for the water supply P1 and P5 at the Felipe Camar?o district, and P2 at Planalto, from May/2014 to May/2015. The survey results show that there are contamination of the water intended for human consumption in those districts, and that this stems from the improper disposal of solid waste in the soil, beyond the absence of adequate sanitation, concluding that there are a latent need for public policies that mitigate such problems in the socio-environmental context of this area of study.
