Resumo
O município de Botucatu está localizado na região centro-sul do Estado de São Paulo, a 230 km da capital, com altitudes variando de 400 a 950 metros. Essa geomorfologia propicia a formação de quedas d’água, cujo relevo chamado “Cuesta” é divisor de águas entre a Bacia do Rio Paranapanema e a Bacia do Rio Tietê. É na microbacia do Alto Rio Capivara (Bacia do Tietê) onde está situado o Parque Natural Municipal Cachoeira da Marta, Unidade de Conservação de Proteção Integral, conhecido como “Parque da Marta”, tendo como principal atrativo a Cachoeira da Marta (38 metros de queda d’água), sendo um local muito procurado para a prática de atividades de lazer e ecoturismo. A Cachoeira é abastecida pelas águas do Córrego do Roseira, tendo como principal afluente o Córrego do Canela, que ao se juntarem, formam o Rio Capivara. O presente estudo teve como objetivos avaliar as condições limnológicas de balneabilidade da Cachoeira da Marta em interface com as possíveis fontes potenciais de poluição para propor medidas de recuperação e conservação através da analise dos parâmetros físico-químicos (TºC da água, pH, Condutividade elétrica, Oxigênio dissolvido, Nitrogênio total e Fósforo total) e microbiológicos (Coliformes totais e termotolerantes). As coletas de água foram bimensais durante 12 meses, de Junho/2009 a Maio/2010, em 5 pontos amostrais diferentes, sendo 3 pontos (P1, P2 e P3) no Córrego do Roseira, 1 ponto na junção dos Córregos do Roseira e Canela (P4) e 1 ponto no Córrego do Canela (P5). Os P2, P3 e P4 se localizavam dento do Parque da Marta. Para a comparação das médias nos pontos amostrais foi realizada a analise de variância (ANOVA) seguidas do Teste de Tukey (Tukey’s Studentized Range – HSD) para as variáveis que apresentaram distribuição normal e o teste não paramétrico de Kruskal-Wallis para as variáveis...
Botucatu is a municipality located in the central south region of Sao Paulo State, 230 km away from de the capital at altitudes ranging from 400 to 950 meters. The landforms in this region favor the formation of waterfalls; the relief, called “Cuesta” is a water divisor for the watersheds of Paranapanema and Tiete Rivers. In the micro-watershed of Capivara Highest River (Tiete watershed) is located the Marta’s Waterfall Natural Park, a protected area, know as “Marta’s Park”, where the Marta’s waterfall (38 meters by heigh) is the principal atractive and have been searched for tourism and leisure activities. The waterfall is supply by the Roseira River and his principal tributary is the Canela River and when they to join up, they transformer in the Capivara River. This study aimed to evaluate the limnological conditions for the bathing water quality by the Marta’s Waterfall associated with the possible potential source by pollution and suggest conservation and recovery measures through the physicochemical (water temperature (ºC), pH, eletric condutivity, dissolved oxigen, total nitrogen, total phosporus) and microbiological parameters (total and thermotolerants coliforms). The water samples were bimonthly collected for 12 months, between June/2009 ande May/2010, in different sites over the streams , in 5 diffrents collections sites, 3 sites (P1, P2 e P3) are inside in Roseira River, 1 site in the joiing at Roseira and Canela Rivers (P4) e 1 site located in Canela River (P5). For comparison of medias in the collections sites was realized the variance analisys (ANOVA) followed by the Tukey’s Studentized Range (HSD) for the medias that showed normal distribution and the nonparametric Kruskal-Wallis test for the medias that doesn’t showed normal distribuition, both in the 5% significance level. In the collection sites 1 and 5 were founded medias for dissolved oxigen... (Complete abstract click electronic access below)
