Domestic water quality monitoring at Seberang Perai Tengah, Pulau Pinang / Siti Rohany Sharuddin

As Penang marches towards the 21st Century, our water demand will continue to
increase, even as water supply issues become increasingly complex. As such, we need to
manage water supply more effectively and innovatively. It also to determine the value of
pH, suspended solid (SS), turbidity, residual chlorine and conductivity of the domestic
water supplied in Seberang Perai Tengah according the sampling point are Kampung
Paya, Kubang Semang, Kubang Ulu, Permatang Pasir and Permatang. The results
obtained are expected to fulfill the Malaysian Standard and WHO. From the sampling
result raw water and treated water, the results observed the change of the concentration
of the sample before and after treatment for pH, turbidity and residual chlorine. The
comparison were made between the result obtain with the standard quality of water. It is
obtained that the result fulfills the Effluent Discharge Standards to Malaysian Inland
Waters, Standard A. In water quality study, samples were taken from sampling points
and treatment plants in Pulau Pinang. The laboratory test on water quality was
conducted. The samples were taken one time every week, started from July 25, 2006 until
August 29, 2006. Each sample taken was tested to determine the values of pH, SS,
conductivity, turbidity and residual chlorine. The comparison were made between the
result obtain with the standard quality of water. It is concluded that the result fulfills the
National Standard for Drinking Water.
