Trouble with chlorinated water
Q: We recently got connected to Maynilad. After many years of buying dirty water from delivery trucks, we finally have potable water coming out off our faucets. I know Maynilad water is potable, but does it not contain chlorine? I think I read somewhere that drinking chlorinated water carries some health risks? Is this true? –Enrico P., Las Pinas City
A: Yes, Maynilad chlorinates water as part of its process for making its water potable. Chlorine is perhaps the most commonly used disinfectant worldwide. At its usual concentration in drinking water (two to three parts per million), chlorine is very effective in killing most disease-causing or pathogenic microorganisms—bacteria, viruses and parasites including protozoa—except for a few hardy species (e.g., the protozoa cryptosporidium).
At present, there are substances and devices available in the market that can remove DPBs or the organic substances that serve as precursor of DPBs from chlorinated drinking water. One of the cheapest among these is activated carbon which removes chloroform and other DPBs. Thus, if you filter your tap water with a device or filter that contains activated carbon, this will surely reduce your health risks from DPBs.
