AB  - Introduction: Aluminium violations in public drinking water facilities were become a great concern to public health. Excessive contamination of aluminium to human due to chronic exposure may affect the human health. Hence, this cross sectional study was conducted at Hulu Langat (HL) and Petaling Jaya (PJ) districts in Selangor. This study was to determine aluminium concentration in drinking water and its associated health effects among respondents at residential areas from two districts in Selangor. Methodology: A total of 80 respondents who fulfilled both the inclusive and exclusive criteria were selected through purposive sampling. Water samples were taken from each respondent’— house using 250mL high-density polyethylene (HDPE) bottles and 0.4mL of 69% pure concentrated nitric  acid was added as preservatives and it’s being analyzed using the Graphite Furnace Atomic Absorption Spectrophotometer (AAS) brand. Respondents’ weight was measured by using SECA weighing scale. Questionnaires were used to obtain both demographic data and the current health status information.  Memory abilities were assessed using the memory tests in Neurobehavioral Core Test Battery by the World Health Organization (WHO). Result: The result showed that there were no significant differences (p>0.05) of aluminium concentration in drinking water at both study areas. There were significant differences (p<0.05) of aluminum concentration of drinking water from the two study areas, with the mean of 0.07 mg/L and 0.08 mg/L with Malaysian drinking Water Standard (0.2 mg/kg/day). In addition, there were no significant differences (p>0.05) of Chronic Daily Intake (CDI) of aluminium intake between both study areas. It was also found that Hazard Index (HI) showed that none respondents had HI more than 1. Lastly, there are no significant correlation (p>0.05) between aluminium concentration in drinking water and the memory ability score. Conclusion As a conclusion, the aluminium concentration in drinking water at Petaling jaya districts showed a higher level as compare to Hulu Langat districts. Besides, all respondents in both study areas had no risk due to exposure of aluminum in drinking water. Statistically, this study showed there were no correlations between the aluminum in drinking water with memory abilities score. Keywords: Aluminum, Chronic Daily Intake (CDI), Hazard Index (HI), Health Risk Assessment, Memory Ablilities.
