The water pollution is one of the problems of major transcendency in the modern cities and his principal contaminating agent is the urban population across the domestic and agricultural waste, Moyobamba's city, located in the High place Jungle of the San Martín region in Peru, is not an exception if not that also contributes to the pollution of one of the most important rivers of the region. To determine the microbiological pollution of the Rio May by microbiological pollutants, by incident of the unloads of waste water proceeding from Moyobamba's city, there appeared this investigation that it has taken as a title " Determination of the concentration of coliformes fecal and total in the May river, for incident of the unload of waste water of Moyobamba's city, 2009", the area of study there understood the sector Juan Antonio who is upstream from Tahuishco's port, Moyobamba's city, Moyobamba's Province, Region San Martin. I raise a general aim that was to determine the concentration of coliformes fecal and total in the May river, for incident of the unload of waste water of Moyobamba's city and as specific aims the investigation considered to determine the microbial concentration of coliformes fecal and total, as indicator of pollution of the Rio In May; to determine the possible environmental risks and in the health of the bordering population, for incident of the unload of waste water of Moyobamba's city on the May river and to raise alternatives of solution for the suitable final disposition of the waste water of Moyobamba's city. To achieve the aims of the project fieldworks and office developed, in the field stage stations of sampling decided in the dump and in the body recipient, since additional analysis decided the capacity of dispersion that presents the May river with regard to coliformes total and fecal, likewise they identified, qualified and valued environmental impacts generated by the unload of the waste water of Moyobamba's city, finally alternatives of solution appeared to correct the impacts that are generated. With the investigation, it is known that the May River presents high concentrations of coliformes fecal and total before the dump has influence, but it is known also that in 50 meters the river presents a high capacity of natural purification, being able to diminish even in 99 % the bacterial concentrations registered in the source. In addition using statistical models of linear simple correlation, I come to him to the conclusion that exists relation of moderated to significantly between the volumes of waste water unloaded to the May river and the increase of coliformes total in the May river, whereas for coliformes fecal the relation of reason - effect is moderately acceptable. On the other hand the unload of waste water in the Rio In May from Moyobamba's city, quantitatively they generate an impact of-10.56 (value adimensional numeral checks 2.4.4) what qualitatively represents a moderate impact, of negative character with major incident on the socioeconomic way (public health) and in the physical way (Air - quality), to correct these impacts there appears the formulation of a project of public investment for the improvement of the system of evacuation and final disposition of waste water of Moyobamba's city, the above mentioned project has to contemplate construction of lagoons of stabilization with primary and secondary treatments, besides a program of environmental education orientated to avoiding risks in the health of the population for consumption of contaminated fish.
