Arsenic›

A contaminant or monitoring group tracked on this system's federal record.

EPA drinking-water standards →
Coliform bacteria›

The Revised Total Coliform Rule tracks coliform bacteria — an indicator that disease-causing organisms could be getting into the water.

Read the rule → EPA · Coliform Rule
Haloacetic Acids (HAA5)›

Haloacetic acids are disinfection byproducts formed when chlorine treats water; five are federally capped as a group.

Read the rule → EPA · Disinfection Byproducts Rules
Lead & Copper Rule›

The Lead & Copper Rule requires utilities to test water at customer taps for lead and copper — metals that enter water from pipes and plumbing, not the source. EPA's health goal (MCLG) for lead is 0. Lead is regulated with an action level rather than a standard MCL.

Surface Water Treatment›

The Surface Water Treatment Rules require utilities using surface water (or groundwater under its influence) to filter and disinfect against microbes like Giardia, Legionella and viruses.

Total Trihalomethanes (TTHM)›

Total trihalomethanes are cancer-linked byproducts formed when chlorine disinfects water; federal rules cap them and require regular testing.

// know first · then build

Know first. Then build the right water setup.

Start by finding out what's actually in your water. Then build from the foundation up: protect the house, upgrade what you drink, and add the hydrogen experience that fits your life.

1 Start here

Know what's coming out of your tap

Tap Score home water test · Essential City Water Test

Don't guess about your water. Public records describe your water system; a home test shows what's in the water at your own faucet. It doesn't diagnose anything.

Test my water

How the lab test works
  • It's a mail-to-lab test, not an instant strip. Some kits add a quick home pH or chlorine strip.
  • One kit = one sample from one faucet, one time. You fill the bottles and send them to the lab.
  • Activate it online, fill the bottles exactly as directed, and ship it the same day, ideally Monday to Wednesday. A FedEx label is included; U.S. return shipping is free.
  • Results online in about 5 lab business days after the lab receives it (PFAS: 10). With shipping, that's roughly 1–2 weeks door to door.
  • Tested by accredited independent labs (SimpleLab's network). Your report compares results with EPA limits and health goals, and free expert help is included.
  • What's covered: Lead & Copper 3 contaminants · Essential 49–56 · Advanced 111–116 · PFAS 18.
  • For your own information, not for real-estate or legal use.
