Hydrogen Sulfide (H2S) Water Test

1 Analyte Tested
See Full List

Recommended for targeted testing for hydrogen sulfide (H2S) dissolved in drinking water. Hydrogen sulfide (H2S) gas is one of the most common explanations for a rotten egg or sulfur smell in drinking water. While hydrogen sulfide does not typically present a health risk in domestic drinking supplies, it is a nuisance and can contribute to your water’s acidity—leaching potentially hazardous metals from plumbing and appliances.

This Tap Score water test package provides all required materials to properly collect and submit a sample for certified laboratory testing. Reported results will include detailed, quantified analysis of hydrogen sulfide.

Hydrogen Sulfide (H2S) Water Test

Is this the right test for you?

What our scientists say:

“ Hydrogen sulfide–also known as H2S gas–is produced as microbes break down organic materials in the absence of oxygen. H2S gas, while typically not harmful in concentrations found in drinking water, can lead to an off putting "sewer" or "rotten egg" odor. "

This is the right test if you:

    • Served by a private or shared well.
    • Water tastes or smells like rotten eggs.

Sampling Instructions

Every test comes with step by step instructions on how to prepare your water source, collect your water sample, and prepare your sample for return shipment to our labs.

Collection Bottles

Your kit includes all the bottles, tubes or vials necessary to collect your water sample. For most kits, however, there is only one collection bottle needed.

Sample Information Card

Your kit includes a postcard that asks for a few details about how and where you collected your sample (i.e. kitchen faucet). Just fill it out, drop it in the return box, and we'll do the rest.

Prepaid Shipping Label

Shipping is always on us. This package includes a prepaid priority shipping label to the lab. Just stick the provided label on the outside of the box and drop it in the mail.

Return Container (If Applicable)

Some of our tests require your water sample to be cold when it reaches our labs. If this applies to your test, the proper refrigeration items will be included.

Your custom
Tap Score
awaits.

After our certified labs receive and test your water sample, we will email your custom Tap Score Report, a simple digital tool that helps you understand exactly what’s in your water and what you can do about it.

Customer Kudos

"It was easy and gave us a lot of good details. We learned that we do not have arsenic in our well water. We also learned our water is super hard and the report actually said "do not water your plants with this water, it will kill them" I just thought I sucked at growing plants, it's nice to know its not me, it's the hard water."

AMAZON CUSTOMER

"This test is worth it. It is the same price or cheaper than any lab I've seen, but you just mail it in. The results were were extremely detailed and the online interface is very user-friendly and easy to understand."

AMAZON CUSTOMER

Simple interface and useful information make this a good value. I live in a 1956 airspace condo with good pipes but bad maintenance, so for everyone’s peace of mind I went ahead and got this done (and also previously ran basic asbestos tests on the plasterboard and ceiling popcorn. We’re all good here!

The testing done is superior to what we had done by a local company. This makes it an excellent value for those of us that are on our own wells. If you want a water test that is outstanding check these folks out.
