Esse trabalho trata do diagnóstico dos poços tubulares profundos e da qualidade das águas subterrâneas na bacia do rio Jacutinga e Sub-Bacias Contíguas, localizada na região centro-oeste de Santa Catarina, Sul do Brasil. No território da bacia foram identificados 2.477 poços perfurados, distribuídos numa área de 2.170 Km². Destes, 1.531 poços estão em operação e 648 foram considerados secos. A análise das informações incluem, além da qualidade da água de 100 poços de uso comunitário, as características hidrodinâmicas, aspectos construtivos dos poços e uso da água. Foi observado um número expressivo de poços com a qualidade de água comprometida, principalmente do ponto de vista microbiológico. Essas informações constituem um importante subsídio na tomada de decisões para o planejamento e execução dos programas de gestão integrada da água, objetivando a proteção e uso sustentável deste recurso. The aim of this work was a diagnosis of deep wells and groundwater quality in the Jacutinga River basin and its contiguous sub-basins, located in the mid-west region of Santa Catarina State, southern Brazil. It was identified 2,477 deep wells in the basin territory, an area of 2,170 km². From this total 1,531 are in operation and 648 are dry. The results include, besides the water quality analysis of 100 community wells, the hydrodynamic characteristics, constructive aspects of the well and the main use of water. A significant number of wells with impaired quality of water, especially microbiologically, were observed. This information constitutes large subsidies in decision-making for planning, implementation and management of integrated water programs for protection and sustainable use.

The tropical peatlands of southern Brazil are essential for the maintenance ofthe Atlantic Rain Forest, one of the 25 hotspots of biodiversity in the world.Although diazotrophic micro-organisms are essential for the maintenance ofthis nitrogen limited ecosystem, so far studies have focused only on micro-organisms involved in the carbon cycle. In this work, peat samples werecollected from three tropical peatland regions during dry and rainy seasonsand their chemical and microbial characteristics were evaluated. Our resultsshowed that the structure of the diazotrophic communities in the Braziliantropical peatlands differs in the evaluated seasons. The abundance of the genusBradyrhizobiumshowed to be affected by rainfall and peat pH. Despite theshifts of the nitrogen-fixing population in the tropical peatland caused byseasonality it showed to be constantly dominated bya-Proteobacteria followedbyCyanobacteria. In addition, more than 50% ofnifHgene sequences have notbeen classified, indicating the necessity for more studies in tropical peatland,since the reduction of N supply in the peatlands stimulates the recalcitrantorganic matter decomposition performed by peatland micro-organisms,influencing the C stock.
This manuscript reports the first ecological study of tropical peat-lands diazotrophic communities from the Brazilian Atlantic Rain Forest, one of the world?s largestbiodiversity hotspots. Based on culturing and culture-independent approaches, our results showed alter-ations in the structure of the diazotrophic communities in different seasons. The genusBradyrhizobiumabundance was affected by rainfall and peat pH. In addition, the great number of unclassifiednitrogen-fixing bacteria indicated the need for additional studies to guide future mitigation actions,since the reduction of N supply in the peatlands stimulates the recalcitrant organic matter decomposi-tion performed by peatland micro-organisms, influencing the C stock.
