Abstract:
This study was conducted to assess the water quality in Kerteh River. The
healthy of Kerteh River was determine using water quality index method. Two
sampling were conducted in April and October. Six sampling stations were selected
along the Kerteh River. Water quality parameters analyzed were total suspended
solids (TSS), turbidity, dissolved oxygen (DO), ammoniacal nitrogen (AN),
biochemical oxygen demand (BOD), chemical oxygen demand (COD), pH and total
fecal coliform. Total coliform distribution at Kerteh river was 88 count/lOOml(Class
I) for first sampling and 299 count/I OOml(Class IIA) for second sampling.
Classification according to Water Quality Indices shows that the average WQI for
first sampling was 81 (Clean) and 73 ( Slightly polluted) for the second sampling. The
condition of Kerteh river is still under control and conventional treatment should be
done for water use sustainable.
