I did a water test that I purchased from amazon that tests for bacteria, lead, pesticides, nitrites/nitrates, chlorine, hardness, and pH and everything was 100% safe.
EDIT: here is the pack I used: https://www.amazon.com/gp/product/B000FBMAVQ/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1
If you're that worried about tap water in your location, test it. You can get water testing kits very easily for cheap.
First Alert WT1 Drinking Water Test Kit https://smile.amazon.com/dp/B000FBMAVQ/ref=cm_sw_r_cp_apa_i_P46NCbF2KGCJS
If you're still worried, you can install water filters for your whole home, or even just for your kitchen tap.
The environmental damage done by single use water bottles is truly immense.
I tested my water like 2 days before the story came out, and it resulted negative for lead.
Oh! My bad, you are right.
OP said 'fast' though and shipping it somewhere doesn't do that.
here is a strip test that does lead: https://www.amazon.com/First-Alert-WT1-Drinking-Water/dp/B000FBMAVQ
In a previous water related thread, someone posted this one
Ah. Test the water?

Here's a simple and cheap one: http://www.amazon.com/First-Alert-WT1-Drinking-Water/dp/B000FBMAVQ/
Here's a more expensive and more complete one: http://www.amazon.com/Watts-Premier-173006-All--Water/dp/B002XISS4C/

Nope. Try a water testing kit. You can also get a lead testing kit for free from Multnomah County.
If you're worried, you can buy a test kit on Amazon: Link
Hmm, I'd be shocked if one of us discovered a substance we could get at home that would create an as-of-yet-undiscovered precipitation reaction that would precipitate chloramine out of water! The reaction with citric acid you mentioned, is another one I now remember I've heard. All the points you make are right on, so if you figure something out, let us know! BUT the first step in my mind is finding a way to verify any potential results, so we're back to a cost effective way of measuring chloramine levels in a given water sample.
The cheap test strips for drinking water and aquariums seem to only test for chlorine (http://www.amazon.com/dp/B000FBMAVQ/)($13), and the expensive ones seem to indicate they CAN be calibrated to check for chloramine (http://www.amazon.com/dp/B00I4TFU1I/) ($1,099). This seems made specifically to test for chloramine, but it's unavailable (http://www.amazon.com/dp/B00R3EF7ZY/).
I'll bet small quantities of citric acid are fine, and small amount of humic acids are definitely beneficial (humic acid is naturally occurring in compost and is great for soil). How much is too much, idk, since I don't add any directly/intentionally.
In the exceptionally unlikely case that you are correct, you can get a test kit for super cheap. If it tests positive (spoiler, it won't), hit your local library and learn how to draft a properly formed certified letter demanding specific action of your landlord to fix contaminating pipes, and withhold your rent until it is fixed. There. You can solve your problems. Stop complaining and DO something to better your situation in life.
Lead paint? No. As I linked elsewhere in the thread, a drinking water test kit. If you boil water in your cast iron and the water doesn't test positive for lead, then you know it's safe.
Yeah, a new skillet can be had for cheap, because they are not milled flat like vintage ones are and also often lack the handle reinforcement present in antique skillets. Or you could search out another vintage Griswold (which I never claimed OP had, pure speculation), but this time have no idea if it's been used to melt lead before or not. But OP already has a skillet, if it can be made safe, why throw away something you could pass down to your grandchildren because of an irrational fear you are unwilling to prove wrong?
You are right, to each their own, you can discard a usable, heirloom quality item potentially worth hundreds of dollars due to your self-described paranoia. I'll let rationality and cheap, easily available scientific testing guide my own actions.
