Look, sometimes you do all the tests and you’re still not sure. Maybe the smell comes and goes, or you get a weird black slime in your toilet tank. That’s the point where you can call a water testing lab.
They’ll send you a sterile bottle in the mail. You fill it up, pop it back in the box, and wait for a report that reads like a science report card. It’s actually kind of exciting—like waiting for your DNA test results, but for your tap water.
The lab will tell you exactly what type of sulfur you have, and if there are any other uninvited guests (like iron or manganese) crashing your water party.
