Summary: | Groundwater quality whether at urban or rural area can be influenced by natural factors
and anthropogenic activities. Urbanisation, agriculture and industrial are examples of
anthropogenic activities while interactions of rocks, soils, natural disasters are natural
factors that can influence quality of groundwater. In this study, a total number of 60
water samples were collected from wells at urban and rural area. Water sample were
analysed for water quality and heavy metal parameters. The results were compared to
standard drinking water by Ministry of Health (MOH) and Interim National Water
Quality Standard (INWQS) for classification of Water Quality Index (WQI) value.
Result indicates that well water quality of sampling locations was classified to class III.
The value for each parameter are in the range of 4.44 - 7.7 mg / L, 1.0-3.8 mg / L, 4.7-
60 mg / L, 0.01- 1.0 mg / L, 0.7- 13.7 mg / L, 4.3-8.0 for DO, BOD, COD, NH3N, SS
and pH respectively and undetected to 3.9 mg / L, undetected to 0.005mg / L, 0002-
0009 mg / L, 0001 -0009 mg / L for Fe, Cd, Mn and Pb content respectively.
Comparison of water quality and heavy metals parameters between Kota Bharu and
Pasir Puteh was carried out using an independent t-test. The results showed significant
differences between the two areas, with p <0.05 except for both Fe and Mn which
showed p >0.05.
