Abstract:
goods and services on which human beings depend. The present study analyzed the physico
chemical parameters and nutrients enrichment in rivers Kisat and Auji as well as wastewater
sedimentation ponds to inform appropriate management measures. The water samples were
collected from eight sampling sites starting at the source running downstream and at the
wastewater sedimentation ponds beginning from February to October 2021. The physico
chemical parameters were measured in situ, while nutrients were analyzed at the laboratory.
The results of the study indicated inconsistencies in the variation of physico-chemical
parameters and nutrients enrichment among the sampling sites. The results revealed that
dissolved oxygen (DO), electrical conductivity (EC), salinity (sal), total dissolved solids
(TDS), turbidity and total nitrogen (TN) showed significance difference between the sites.
Similarly principal component analysis revealed variations indicating (temperature, TDS, EC,
Sal, TN and Total phosphorus (TP) are the major variables influencing the water quality
variations. The overall results demonstrated some sampling sites are heavily contaminated with
pollutants attributable to anthropogenic activities. The results of the present study are important
for decision making regarding the management of water quality in urban rivers and wastewater
sedimentations ponds.
