Study of spring water quality at Jalan Batu Arang, Puncak Alam / Syed Mohd Fahimi Syed Mokhtar

A cross-sectional study was conducted at Jalan Batu Arang, Puncak Alam from November 2010 until April 2011. The main objective of this study is to determine the spring water quality at Puncak Alam in term of physical, chemical, and biological parameter. A total of 50 people were selected as respondents and 40 water samples was analysed in this study. From the water analysis, most of the parameter shows on no violation occurrence except for five parameters that are pH, Cadmium, Nitrite, E.coli and Total Coliform. The descriptive statistical analysis was used to get the mean result for all parameter. Next, the independent t-test was used to look on significant different on spring water quality between dry and wet days, and between two pipes. There are significant means different for cadmium with p value (p = 0.00), for nitrite with p value (p = 0.00), for sulphite with p value (p = 0.001 ), for E.Coli with p value (p = 0.00) and for Total Coliform with p value (p = 0.003). Next there are significant different of water quality between two pipes, for Cadmium with p value (p = 0.004), for sulphite with p value (p = 0.00), for E.Coli with p value (p = 0.002), and Total Coliform with p value (p = 0.003). There are strong correlation between cadmium and conductivity, between nitrite and conductivity, and strong negative correlation between E.Coli and Total Coliform with dissolve oxygen level. The Chronic Daily Ingestion and Hazard Index were calculated for ala respondents, the mean shows on value 0.062 for cadmium, and 0.074 for nitrite. In conclusion, the water quality of this spring water is not good for human consummation, this is due to violation occurred in some chemical parameter, and both biological parameter, the water quality become worse after the rain day. Public should avoid this kind of water in order to prevent any health effect after chronic exposure.
