Here’s the tricky part: iron in well water shows up in two main flavors. You’ve got ferrous iron, which is completely dissolved—so your water looks clear when first poured, but turns rusty after sitting out for a bit. It’s like a magic trick nobody wants.
Then there’s ferric iron, which is already solid and gives the water that instant orange-brown look. Think of it as the angry, visible iron that stains everything it touches. Most people have a mix of both, because water loves to be complicated.
Your first step? Fill a clear glass from the tap right now—go ahead, I’ll wait. If it’s clear and turns rusty in 30 minutes, you’ve got dissolved iron on your hands. If it’s already rusty, you’re dealing with the solid stuff. Knowing this decides your strategy.
