What Causing the Contamination?

Kuala Lumpur tap water is generally safe to drink as chlorination during the treatment process would have killed any bacteria present in water. However, there were other factors to be considered.

Tap water is safer if a person’s lives near the water treatment plant and has new main water pipes. New pipes must be few years old and not be made from cast iron which can corrode over time. Piping in homes, if left unchanged, is also susceptible to corrosion. Piping might not be corroded if the house is less than 10 years old.

A prominent water expert and university professor in Kuala Lumpur is quoted as saying, “tap water is safe if there are no repairs or upgrading works by the water service provider that can pollute and contaminate the pipe water, and also if there are no leaks in the original pipes or the pipes in your house.”

Conventional water treatment cannot filter heavy metals, organic contaminants, and microbial organisms. Water near agricultural areas may carry harmful organic material from excessive pesticide or fertilizer applications. Water collected near industrial plants can cause also contain pollutants that are not eliminated during conventional water treatment.
