Quality of the aquatic environment of high Andean rivers evaluated through environmental indicators: a case of the Cunas River, Peru

ABSTRACT The quality of the aquatic environment of the Cunas River was evaluated through environmental indicators, in two contrasting climatic periods. Anthropogenic pressures on the aquatic environment were identified, and the BOD5 load contributed by the wastewater was determined. Water samples an...

Anthropogenic pressures on the aquatic environment were identified, and the BOD5 load contributed by the wastewater was determined. Water samples and benthic macroinvertebrates were collected, and water quality and trophic status were determined. The BOD5 load contributed by wastewater from fish, livestock, and urban activities was 23,27kg/ day, 284,31 kg/day and 349,70 kg/day. The water quality of sectors S1, S2 and S3, according to the EPT, (Ephemeroptera, Plecoptera, Trichoptera), BMWP (Biological Monitoring Working Party) and H' (Shannon-Wiener diversity index) was good, regular and poor, respectively. According to the INSF (National Sanitation Foundation Index of the United States of America), the S1 and S2 presented good water quality and the S3 average water quality. According to the chlorophyll a, the three sectors had low trophic levels.
