Good point. The more detailed data reveal that the pollutants in Columbus tap water are within the legal limits, but exceed other federal health guidelines.
Thanks for the link. I'm studying some of those numbers but I'm still not sure exactly what they mean. ;)
they are measured in parts per billion or parts per million and less is better
Just for comparison's sake you can taste the presence of salt in water when it gets up around 1-2 parts per thousand. Brackish water has salt content around 5-7 parts per thousand and ocean water is up around 23-26 parts per thousand if I recall correctly.
Two guidelines:health and legal limit. Health means exactly that, anything over that limit means a health risk, anything over legal means they can be shutdown till its fixed. FAQ's have an item about avoiding the water if you are on chemo or have an immune disease.
all sorts of things are not tested for and may or may not be present in the water
is it safe? that's relative. More than 1 million people live in the watershed area here and farmland too along with some industry. All of it ends up in the water. We are all guinea pigs in drinking or using the resulting cocktail after its treated. We still haven't learned how not to foul our own nests.
I know from delivering the samples all the time years ago this stuff does get tested and tested often like bi-weekly minimum. Even Annheiser Busch has their water tested weekly so they know what is going in their beer. Guess that makes sense as Columbus' biggest water consumer. Zandi labs and another who's name escapes me at the moment does most of it. So even if you drink Pepsi or Budweiser that's made locally you are still drinking our tapwater, no escaping it.
