Relations fecal coliforms/ fecal Streptococci as indicators of the origin of fecal pollution in urban and rural water bodies of Temuco, Chile

The presence of alloctone bacteria isconsidered as one of the more important biological pollutants of water bodies, existing one close relation between the fecal contamination indicators and the existence of urban and industrial zones. In the present study we utilized indicators of fecal contaminati...
