Previous issue date: 2017-02-01 / Pontif?cia Universidade Cat?lica de Campinas ? PUC Campinas / Funda??o de Amparo ? Pesquisa do Estado de S?o Paulo - FAPESP / Recent urban growth has led to a significant reduction of permeable areas in the cities and consequently a degradation of water resources. The watershed are considered basic units of study and management in environmental planning; thus these study aimed to analyze the relationship between eight indicators of water quality (pH, turbidity, temperature, dissolved oxygen, biochemical oxygen demand, total phosphorus, total nitrogen and total dissolved solids) and the environmental impacts at sampling points located in six different drainage areas in the Ribeir?o das Pedras watershed, Campinas/SP. The samplings were collected in 2015/October, January, April and July/2016 and the results were compared with CONAMA Resolution n.?. 357/2005 (Class II). The results showed that there is a direct relation between the land uses and occupations with the water quality, it comes as seasonal interferences verified by the precipitation in the period of study. Therefore, it?s important to schedule periodic analyzes of municipal water bodies in order to verify the interferences that are occurring in them, as well as it?s necessary to supervise the commercial venture with their own treatment plants, so that there?s no degradation of these water bodies. / O crescimento urbano verificado nos ?ltimos tempos vem promovendo uma diminui??o significativa das ?reas perme?veis nas cidades e consequentemente uma degrada??o dos recursos h?dricos. As bacias hidrogr?ficas s?o consideradas unidades b?sicas de estudo e gest?o no planejamento ambiental; assim o presente estudo teve por objetivo analisar a rela??o entre oito indicadores de qualidade da ?gua (pH, turbidez, temperatura, oxig?nio dissolvido, demanda bioqu?mica de oxig?nio, f?sforo total, nitrog?nio total e s?lidos totais dissolvidos) e os impactos ambientais em pontos de amostragem localizados no exut?rio de seis diferentes ?reas de drenagem na microbacia do Ribeir?o das Pedras, Campinas/SP. As amostragens foram realizadas nos meses de Outubro/2015, Janeiro, Abril e Julho/2016, sendo os resultados obtidos comparados com a Resolu??o n.? 357/2005 do CONAMA (Classe II). Com os resultados observou-se que h? uma rela??o direta entre os usos e ocupa??es do solo com a qualidade da ?gua, vem como interfer?ncias sazonais verificadas pela precipita??o no per?odo de estudo. Ressalta-se, portanto, a import?ncia da programa??o de an?lises peri?dicas dos corpos d??gua municipais, a fim de verificar as interfer?ncias ocorridas nos mesmos, assim como ? necess?rio que sejam fiscalizados os empreendimentos com esta??es de tratamento pr?prias, para que n?o haja degrada??o dos corpos d??gua por estes.
