From the Facebook page of COWDThe COWD said its laboratories conduct daily physical, chemical, and microbiological tests and said test results have so far shown no signs of contamination. The water utility said it conducted a potability test following a prominent mall’s request on September 17 and said that while results showed clean water before the service connection, it was water from the mall’s own facilities which tested positive. “We advised them to clean their tanks,” COWD General Manager, Edna Najeal said. Najeal reminded establishments and residents who have their own water tanks to regularly clean them as these could be the source of contamination. COWD Board of Director Gerry Caño, meanwhile, said that while COWD secures water “up to the meter,” businesses selling or storing water for drinking, irrigation, or industrial use, fall under the responsibility of government agencies.
