The cheapest, most dramatic fix is chlorine shock treatment. That’s right—you pour a calculated amount of household bleach (chlorine) directly into your well. It sounds insane, like you’re trying to sanitize a swimming pool underground, but it actually kills the sulfur bacteria.
Warning: This is not a “pour and pray” situation. You have to circulate the chlorine through your entire plumbing system, let it sit for 12–24 hours, then flush it all out until the bleach smell disappears. You’ll basically turn your house into a giant, chlorinated water park for a day. Then, the sulfur smell vanishes—for a few weeks or months.
