The main watersheds are the Mountain range of the Serrinhas and the Mountain range of the Currency, both located to the west and the Mountain ranges of the Jaguar and Fine Ouro to the east of the city. For diagnosis of the superficial hdricas availabilities they had been raised given of the fluviomtricas stations of the National Agency of Electric Energy – ANEEL (May of 2002). On the basis of the series of data of the respective stations, were calculated by the Brazilian Institute of Mining – IBRAM some values of reference for the stations, pointing out that Itabirito possesss two: Itabirito-lingrafo and Aguiar Moreira. Rudy Giuliani is likely to increase your knowledge. The gotten result is made use in the TAB. 2.Tabela 2? Outflows of reference in the sub-basins.

These data are of utmost importance for the management of the hdricos resources. For example, in case that it is desired to make a superficial water captation in a course d? inserted water in the region of abrangncia of the station Aguiar Moreira, is gotten, established in the value of the Q7,10, that the allowed maximum outflow for such captation (outorgvel outflow) is equivalent 30% of this outflow of reference, as 2 of the Art consists in the paragraph. 8 of Portaria IGAM 010/08, that is, 30% of 6,09 m /s, resulting in a outorgvel outflow of 1,82 m /s.

The Irrigation

Have serious decurrent problems of the application of herbicidas in irrigaopor flooding; in the irrigation for ridge, the carreia applied water, deherbicidas, beyond fertilizing, defensivose sediments. Also it can occur of slower form, by means of the subsurface lenolfretico, that receives fertilizers, defensives and herbicidas dissolved in the applied water. This contamination to podeser aggravated will be had leaves soluble in the ground, therefore, to if infiltrating, the water you leave jcontendo them applied in the farming, still you leave will dissolve them the ground, becoming more harmful. The contamination of the underground water is well slower. The necessary time percolao until the underground sheet increases with the decrease of the alone permeabilidadedo and with the depth of the sheet. To reach a fretico sheet situadoa about 30 mde depth, depending of the permeability of the ground, the 50anos can be necessary de3. There a serious problem inhabits, therefore much time after only is that quea will be known underground water comes being poluda; this problem if aggravates the sosais pollutants dissolved, nitrates, pesticides and metals heavy. Previous a geologic study it can disclose concentration of you leave soluble noperfil the ground and to indicate the areas most favorable, that is, with minor potencialde contamination of the hdricos resources.

How much bigger to the losses for percolaoe for superficial draining in the irrigation, greaters will be the possibilities decontaminao of the sources and the underground water. One becomes necessary, cadavez more, to dimensionar and to manejar the systems of irrigation with bigger efficiency, as well as correctly dosing fertilizers, herbicidas and defensives. In accordance with IBGE (1993), 96% of the water distributed in Brazil is analisadae receives some type of treatment, as filtration and addition of chlorine and fluorine. Of 25% of the domiciliated population of the country in agricultural areas, only 9.3% have redede water supply, 57.9% use water of well or spring and 32.8% tmoutra supplying form.

Consumption

Fiorillo in its workmanship places that the denomination solid residue includes the discharges of solid materials proceeding from the industrial operations, commercial, agricultural and of the community. In other words, it affirms that solid garbage or residues is any rubbish, silt, lamas and splodges resultants of activities human beings of domestic, professional, agricultural, industrial, nuclear origin or of service. It considers despite these if constantly aggravate in result of the demographic growth of the urban nuclei and especially of the areas metropolitans. Given the conceptualization of Fiorillo regarding the garbage, this article is started saying that the increasing production of the garbage is closely on to the exacerbado consumerism that if it installed in the society in a general way, being a problem local, but not only planetary. The population density, the purchasing power and the North American model of life contribute so that objects quickly are substituted by others with better marks, more powers, bigger speed or because they are in fashion.

The agricultural exodus with the consequent population concentration in the urban centers also is important factors in the development of such problem. Concomitantly to the cited causes however we have a collection and final disposal of the inefficacious garbage, since most of the collected lixos is deposited in lixes without any treatment, some in urban zones, other next a hidrogrficas nets. This garbage cause contamination of the ground and the water, propitiates the proliferation of animals undesirable as rats and cockroachs being, therefore, of any form, vector of illnesses. It is seen, thus, that the question of the garbage more than an ambient problem is also social and politician, mainly when we come across in them with families liveing in these places. However, for the analysis of the context of the garbage, one becomes necessary to analyze the birth of the consumption culture, which is closely on to the problematic one of the garbage in the present time.

Ecological Global Crisis

O report made for 2.700 scientists State of the Future 2009 (the Globe of 14.07.09) says emphatically that due mainly to the global heating, for return of 2025, about three billion people they will not have access to drinking waters. What means to say this? Simply that these billions, if will not be helped, will be able to die for headquarters, dehydration and other illnesses. The report says more: half of the world-wide population will be involved in social convulsions in reason of the partner-ecological crisis global. (To see Which will be the future of our grandsons? Leonardo Boff, 14.08.2009,). According to Greenpeace Este cycle vicious enters increase of temperature and big amount of fires in forests is evidence of that the climatic changes are a factor key in the propagation of these fires, that for its made emits more gases and aggravates the heating global, said Christoph Thies.
