| description | This study was carried out at Ranchan Waterfall from November 2013 until March 2014 to assess
water quality level based on National Water Quality Standard (NWQS) for Malaysia. A total of
three sampling stations covering the study area were selected for water sampling and were signated
as Station 1, Station 2 and Station 3. A total of 12 physico-chemical water parameters were
analysed based on APHA and HACH standard method. The results obtained then were compared
with NWQS. Result shows that the range for temperature during the sampling time was 23.80 to
25.30 ˚C, for turbidity was 0.32 to 3.09 NTU, 4.92 to 7.82 for pH , 4.48 to 9.30 mg/L for DO, 1.00
to 12.00 mg/L for TSS, 0.02 to 0.06 mg/L for nitrate, 0.02 to 0.12 for ammoniacal nitrogen and 0.03
to 0.20 mg/L for orthophosphate. According to NWQS (National Water Quality Standard for
Malaysia) classification, the temperature was within the normal ranges, turbidity, conductivity, total
suspended solid (TSS), chemical oxygen demand (COD), dissolve oxygen (DO), nitrate,
orthophosphate, ammoniacal nitrogen were categorized under class I, while biological oxygen
demand (BOD) came under class II and pH under class III. Overall, Ranchan waterfall is safe for
recreational use. |
