Torres, Fillipe Tamiozzo Pereira
Changes in the amount and quality of water threaten human survival and other species on the planet. Given this reality and the need for conservation of water bodies, it is important to carry out diagnoses of the conditions of Permanent Preservation Areas of sources in order to establish adequate procedures for its preservation and restoration where appropriate. Thus, the aim of this study is to map and analyze the environmental impact of the headwaters of the stream Alfenas a tributary of the River Uba (MG). The mapping of sources and assess their conditions, and sharpen the impact on each of them, facilitates the formulation of alternatives for the preservation of these sites. According to the methodology used in the study area, no spring fitted into the great class, eighteen were classified as fair or poor, one as bad and two were classified as good. The lack of protection area is the main factor influencing the environmental impact, since it favors the intensification of other parameters especially the anthropic use. Because of the poor condition of quantity and quality of basin waters, specific programs for protection and conservation of springs should be adopted both by the owners and by the supervisory bodies.
