Water  is  an  irreplaceable  resource  for  all  forms  of  life,  which  varies  in  quality in different categories such as polluted, little polluted, good, regular  and  excellent  due  to  the  interaction  with  sources  of  pollution,  in 2018 Peru adopted the Canadian model " ICA-PE ”instrument with which the variation in the quality of surface waters can be evaluated. The objective  of  this  study  was  to  evaluate  the  variation  in  the  water  quality  of the Coata River in the Maravillas Bridge - Coata Bridge section due to  the  existence  of  polluting  sources.  To  establish  the  variation  in  water  quality between the sampling points ACFC-01 and DCFC-03, the source of contamination FC-02 was located, and FC-04 between the points of DCFC-03 and DCFC-05, from from which water samples were obtained from which 18 parameters required for the calculation of the ICA-PE were analyzed,  the  parameters  were  analyzed  according  to  the  standardized  methods  for  the  analysis  of  drinking  and  residual  water  (AWWA-APHA-2001). The quality of the water of the Coata River for population use  goes  from  the  poor  category  to  regular  due  to  rainfall,  while  for  the  irrigation  of  vegetables  and  animal  drink  it  remains  in  the  regular  category both in dry and rainy periods. The pollutant sources of the Coata River in the Maravillas bridge to Coata bridge stretch do not influence the water quality of the Coata River.
