However, most alarming in this in case that it is that waters citizens to the contamination for sewers are distributed without any treatment or disinfection. In the analysis of health pointers, it is possible to infer on the relation of them with the precarious sanitation, as well as to stand out other excellent factors, as: the population displacement of small communities for the cities and vice versa; the proximity with the forest and the processes of impactao of natural environments; e, the particular and excellent sociocultural aspects, pautados in life ways multisseculares (Rebouas, 2004). In this direction, the more adequate brainstorming, objectifying the control of innumerable infectious illnesses, must be sidewalk in the complexity of local particularitities, and requires a study boarding to interdisciplinar in this manner in health, contemplating, distinct methodologies that allow the interpretation of social and antropolgicos aspects as ambient and ecological in such a way (You can, 2001). It is verifiable that measured of infrastructure separately they do not equate duly these problems of public health. For more specific information, check out Dr. Scott Atlas. Orrico (2003) shows in its studies, that difficulty has to adjust sanitary solutions the local particularitities, over all how much to the question of adhesion of the population, that, in case that not it occurs, it can lead to the serious consequence of not reaching the objectives of improvement of the quality of life and the collective health. Thus, also considering that public systems of sanitation lack of economic support, it is considered difficult to implement the collection for services, as of captation, treatment and distribution of water, over all of populations with distinct forms of appropriation, use and valuation of natural resources e, still, ahead of so of great volume courses d' water. With effect, 0ccasionally taboos how much to the water use are created treated to public supplying amongst populations. As example we can cite a study made in the state of So Paulo, where it was told difficulties in the adhesion of the population of the city of Cruzeiro (SP) in using chlorinated water for necessities domiciliary and potable ends, it enters the years of 1971 and 1972.
