The information provided is also somewhat confusing ... they say this about drinking water
Question: Will this chemical harm my fetus (unborn baby) ?
Answer: There are no known studies showing harm to the fetus as a result of consuming water with MCHM levels below 1 ppm. Although there is no information that suggests harm to the fetus, out of abundance of precaution, pregnant women may wish to consume bottled water until levels of MCHM are undetectable in the water system.
But then say this about cooking with the water ...
I go to restaurants or can I cook with the water?
Answer: Yes. You may continue to use tap water for cooking. It is also safe to consume food which may have been prepared using tap water, as with food cooked in restaurants.
BUT - boiling water does not remove 4-methylcyclohexene methanol, so this doesn't make much sense.
They also say that
Question: May I use ice made with tap water?
Answer: Out of an abundance of caution, if you prefer your drinks cold, use
bottled water to make ice or use ice made with water collected after levels of MCHM are undetectable in the water system.
So, frozen water they suggest against, liquid water than suggest against but say that you can cook with it? I wouldn't order the soup.
Question: May I make my baby’s formula with the tap water?
Answer: Yes, however, if you have a special needs child, for example a premature baby, check with your pediatrician.
