I don't know about the water but the pork meal issue is fake and those who previously reported it apologized already for the error.
I think the Philippine's ranking was boosted by the arnis event, which is the country's national martial arts. It was only in the game lineup twice, in 2005 and this year - both while the Philippines was hosting. I'm surprised no one's complaining about that too yet.
What do you mean by "complaining about that too"? Are you expecting guest countries to complain about the inclusion of Arnis in the sea games? They cannot do that because the host country can include "local" sports or non-olympic as part of the competition from what I know.
Arnis was added to SEAG thrice already (first was 1995). Dancesport was also added after a decade of not being part of the competition.
