This is shocking and really makes me angry! According to international relations graduate and blogger Sass Rogando Sasot, Metro Manila’s tap water contained a potentially cancerous chemical used by water companies to disinfect our water.
Sasot said that the University where she worked has access to peer reviewed journals and since her mind is very playful, she stumbled upon a scientific study published at the Archives of Environmental Contamination and Toxicology saying that 21 locations in Metro Manila were found out to have very dangerous level of potentially cancerous chemical compound called bromate.
Sasot said the title of the scientific study was “Occurrence and Sources of Bromate in Chlorinated Tap Drinking Water in Metropolitan Manila, Philippines.”
The study was conducted by Homer C. Genuino of the Department of Chemistry of the University of Connecticut and Maria Pythias B. Espino of the Institute of Chemistry, College of Science, University of the Philippines, Diliman.
The study was done from October 2006–July 2007. The result got published in 2011, and appeared in Volume 62 in 2012 by the said journal.

PRESIDENT DUTERTE THE PROBLEM IS WAY WORSE!
SCIENTIFIC STUDY FOUND VERY DANGEROUS LEVEL OF POTENTIALLY CANCEROUS BROMATE IN TAP WATER IN 21 LOCATIONS IN METRO MANILA
“…bromate was detected in all of the drinking water samples analyzed. Of
these samples, 98.4% had bromate concentrations well above the current drinking water guideline.”
Ang university po na aking pinagtatrabahuhan ay may access sa mga peer reviewed journals. So dahil sa malikot ang aking pag-iisip ito ang aking natagpuan.
Isang scientificy study published sa Archives of Environmental Contamination and Toxicology.
Ang title po ng scientific study ay:
“Occurrence and Sources of Bromate in Chlorinated Tap Drinking Water in Metropolitan Manila, Philippines”
Ang pag-aaral ay ginawa nina:
Homer C. Genuino ng Department of Chemistry ng University of Connecticut
At ni Maria Pythias B. Espino ng Institute of Chemistry, College of Science, University of the Philippines, Diliman,
Ginawa po nila ang pagsasaliksik from October 2006–July 2007. The result got published in 2011, and appeared in Volume 62 noong 2012 ng journal na nabanggit..
Ang attached na map ay mga lugar kung nasaan ang 21 sampling sites for tap drinking water in the distribution lines are indicated.
Ayon sa study “These sampling sites were carefully selected from cities and municipalities serviced by the two local water-treatment concessionaires: Manila Water Company Inc (MWCI) and Maynilad Water Services, Incorporated (MWSI). MWCI services the UP Diliman campus as well as 11 of the sampling sites: (1) Quezon City (eastern part), (2) Caloocan (northern part), (3) Manila (downtown), (4) Marikina, (5) Pasig, (6) Taguig, (7) Pateros, (8) Makati, (9) Mandaluyong, (10) San Juan, and (11) Muntinlupa. The remaining 10 sites are serviced byMWSI: (12) Manila, (13) Valenzuela, (14) Malabon, (15) Navotas, (16) Pasay, (17) Paran˜aque, (18) Las Pin˜as, (19) Muntinlupa, (20) Quezon City (western part), and (21) Caloocan (southern part).”
Ang bromate po ay potentially carcinogenic sa humans.
Ang resulta ng pag-aaral:
“The average bromate concentration of all tap drinking water samples was 66 lg l-1 (n = 567), almost seven times greater than the current regulatory limit in the country.”
Ibig sabihin po, ang level ng bromate sa tap water ay SEVEN TIMES MORE sa safe limit ng itinakda ng ating bansa. THIS IS FUCKING INSANE!
To give you more perspective, ang maximum bromate contaminant level na safe eh 10 lg l-1 according to the World Health Organization
(WHO), the United States Environmental Protection Agency, and the Drinking Water Commission of the European Union.
You have to pay to read the study. But since I get it for free, I have uploaded a copy and you can read it here:
1 .Bromate is a contaminant of commercially produced solutions of sodium hypochlorite used for disinfection of drinking water. (https://pubs.acs.org/doi/pdf/10.1021/es026400z)
2. Manila Water acknowledged in its website that it is using sodium hypochlorite in treating waste water. Sodium hypochlorite treated water goes back to to the nearest water body. (https://www.manilawater.com/…/water-and-used-water-faciliti….)
3. Maynilad also uses sodium hypochlorite to disinfect groundwater. (http://www.mayniladwater.com.ph/…/Maynilad-Water-Safety-Pla…)
