I hate to break it to you, but since we live in an extremely toxic world, your water probably sucks.

Regardless of whether you’re on well or city water, it’s likely contaminated with countless man-made chemicals.

This guide is dedicated to giving you as many tools and resources as possible to find out what’s in your water.

Testing Your Water Quality

If you don’t currently know what’s lurking in your water, it may be time to figure that out…

Here are a few options for water testing:

  • My Tap Score Lab Testing: This lab provides the best water tests I’ve been able to find. They also present the data in a modern way that’s easy to digest.
  • TDS Meter: These meters can be useful for testing the efficiency of RO and distilled water filtration systems.
  • EWG Drinking Water Standards: This PDF from EWG lists numerous compounds and their federal limits compared with EWG standards. Hint: Go with the EWG standards, and even then, many of these compounds shouldn’t be there at all.
  • EWG Tap Water Database: If you’re on municipal water, and you’re not filtering it… it’s been tested, figure out what’s in it and see if you still feel comfortable drinking it.
  • My Tap Water Database: An alternative source to EWG’s database.
  • Tapp Water European Database: The best European water database I’ve been able to find.
  • CDC My Water’s Fluoride: Find out if fluoride compounds are added to your water source.
  • Fluoridation by Country: Find out if your country participates in water fluoridation.
