The pH of tap water in Malaysia is a crucial factor that affects its quality and safety for consumption. The average pH of tap water in the country typically ranges from 6.70 to 7.99, with an overall average of 7.72. This range is largely due to the use of chlorine for disinfection, which is most effective at a pH below 7. The National Drinking Water Quality Surveillance Programme (NDWQSP) in Malaysia closely monitors the pH levels of tap water across various regions to ensure its safety and compliance with regulatory standards.
Understanding the Factors Affecting Tap Water pH in Malaysia
Several factors can influence the pH levels of tap water in Malaysia, including:
-
Chlorine Disinfection: The use of chlorine for water disinfection is a common practice in Malaysia, and this chemical can lower the pH of tap water, making it more acidic.
-
PVC Pipes and Water Filters: The use of PVC pipes and water filter devices can lead to higher concentrations of BPA (Bisphenol A) in tap water, which can affect its pH levels. A study found that BPA concentrations in tap water samples ranged from 3.5 to 59.8ng/L, with the highest concentrations detected in samples connected to PVC pipes and water filter devices.
-
Geographical Variations: The pH of tap water can vary depending on the region and the source of the water supply, as different water sources may have different mineral compositions and pH levels.

The National Drinking Water Quality Surveillance Programme (NDWQSP) in Malaysia plays a crucial role in monitoring the pH levels of tap water across the country. This program collects and analyzes water samples from various regions to ensure that the pH levels are within the acceptable range for safe consumption.
The acceptable pH range for drinking water in Malaysia is set between 6.5 and 9.0, as per the Malaysian Drinking Water Quality Standards (MDWQS). If the pH levels of tap water fall outside this range, it may indicate the presence of contaminants or other issues that need to be addressed.
Balancing the pH of Tap Water in Malaysia
If the pH of tap water in Malaysia is not within the desired range, there are a few home remedies that can be used to adjust it:
-
Lowering pH: Adding a few drops of lemon juice or vinegar to the water can help lower the pH and make it more acidic.
-
Increasing pH: Adding a pinch of baking soda to the water can help raise the pH and make it more alkaline.
It’s important to note that these home remedies should be used sparingly and with caution, as drastic changes in pH levels can affect the water’s taste and potentially lead to other issues. It’s always best to consult with a professional or refer to the NDWQSP guidelines for the appropriate pH adjustment methods.
Consuming Tap Water in Malaysia
In general, tap water in Malaysia is safe to consume as long as it is clear, not cloudy or yellowish, and has no unusual taste. However, individuals with weakened immune systems or underlying health conditions may want to consider using filtered or bottled water instead, as a precautionary measure.
It’s important to note that the quality and safety of tap water can vary depending on the region and the specific water supply. If you have any concerns about the quality of your tap water, it’s recommended to contact the local water authority or the NDWQSP for further information and guidance.
Conclusion
The pH of tap water in Malaysia is an important factor that affects its quality and safety for consumption. The average pH range of 6.70 to 7.99, with an overall average of 7.72, is largely due to the use of chlorine for disinfection. While tap water in Malaysia is generally safe to consume, certain factors such as the use of PVC pipes and water filters can affect its pH levels. Homeowners can use simple remedies like adding lemon juice or baking soda to adjust the pH, but it’s important to do so with caution. Ultimately, the NDWQSP plays a crucial role in monitoring and regulating the pH of tap water in Malaysia to ensure its safety and compliance with regulatory standards.
