Three more public housing estates have high levels of lead in their drinking water.
These are Hung Yan House in Hung Hom Estate, Tung Wui Estate in Wong Tai Sin and the second phase of Shek Kip Mei Estate, Apple Daily reports, citing Transport and Housing Secretary Anthony Cheung.
The three projects, completed between 2011 and 2012, have more than 4,600 households.
Government inspectors are checking their water supply, Cheung said.
Sixteen out of 74 samples from Hung Yan House were found to have excessive lead, 3.4 times the World Health Organization safety standard and the highest among 21 estates tested so far.
Hung Yan House was built by China State Construction International Holdings Ltd. (03311.HK) which was also the main contractor for Kai Ching Estate.
Kai Ching triggered the contamination scare after a private investigation found high lead content in its water supply.
Tung Wui Estate and Shek Kip Mei Estate Phase Two had four and five samples found to have high lead content, respectively.
Meanwhile, another 33 residents of Kwai Luen Estate, including a pregnant woman, tested positive for excessive lead in their bloodstream.
Cheung said the situation is not out of control.
Full-scale pipe replacement is under way in the affected estates but it’s not known when work will be completed, he said.
Also, the government will continue tests on the drinking water in public housing estates built between 2005 and 2010.
Director of Housing Stanley Ying said residents of these estates can get water from standalone pipes and water trucks.
