Chemistry suck

Have a hard discussion on water chemistry with David yesterday, a topic I've been tried to avoid for longtime. Luckily I still remember some of the basic on charge balance and atomic absorptions. Anyway the lab result look really suck with some exceptional high value on SO4 and Na+. May have to ask Khen to go around and collect some extra samples for a cross check. The difficult thing is how to send water sample to Hanoi, not sure if the post would accept package with water sample inside.
