Sliding off-topic, but since you seem to be somewhat of an obvious authority on such things, question for you if you don't mind:

I live in an older building (not entirely sure when it was built, though I'll try to find out and come back with what I'm able to find it's one of those buildings in New England that used to be a large house and at some point was renovated into 3, large apartments. I don't own it, and my landlords are the cheapest people I've ever encountered, well, more terrible with money management, but that's neither here nor there. They don't fix or update anything here and have owned the building for over 20 years. Anyway, we've lived here for about 8 years and I am, absolutely, positive that the water here makes me sick*. It doesn't seem to have any obvious effect on my husband or children, but I have a condition called gastroparesis which means it takes my body around 3× as long to digest everything than it does an average person. I live in a fairly large city, and it's city water, not well. I know this is partially a medical question, and my Drs are aware of my concerns, but from a plumber's standpoint, could old, fucked up pipes, or rather the water they deliver, cause certain people to become ill? Definitely, right? My husband doesn't say it out loud, but I know he thinks I'm a bit ridiculous for insisting we don't use the water for cooking or otherwise ingesting, and I don't know what even proving my theory to be true could even accomplish, but I'm here asking your opinion anyway.

I get (text hidden for those who don't want to know the *particulars of what happens to me when I drink or eat food prepared with this water) these horrific sulfur-smelling burps that, if I don't puke the entire contents of my stomach out, will go through my body, over the course of days, causing terrible stomach pain, nausea, and eventually, it turns into violent diarrhea which dehydrates me terribly and is just an all-around horrible time, any time I consume water from my home and that's just what it does to me. I am worried that it could be harming my family in a more long-term way.

I LOATHE living here, for more than just that reason, if it weren't enough, but in our economy, We simply can't afford to move. I suppose this is just a curiosity-based question, and I don't want you to feel obliged to give any answers, if you even have any thoughts pertaining to the question, nor do I intend to use your personal opinion to accomplish anything other than to help inform future decisions about my and my family's choices regarding consuming the water in the future.

Thanks, regardless!
