Hydrogen Sulfide Water Test Kit: Rotten Egg Smell Analysis (Certified Lab)
Measure the dissolved hydrogen sulfide behind the rotten-egg smell, plus pH, so a sulfur filter is sized right the first time.
Not sure if you need a hydrogen sulfide water test kit?Call or text Aidan. Tell him what you are seeing (rotten-egg or sewer smell, worse on hot water; tarnished silver) and he will tell you whether this test is the right next step or if a broader panel or a simpler answer fits better. Free, no obligation.

What makes step 4 different from every other water test
Other companies hand you a lab report and say good luck. We are a water treatment company that has solved well and city water problems for over 30 years. The testing is done by an independent, third-party certified lab so the data is unbiased. Then we tell you exactly how to fix what the lab found, and we have the equipment and expertise to back it up.

What fixes it: Iron & Sulfur Filters (Air Injection)
Air-injection Katalox-Light filters oxidize and remove hydrogen sulfide and iron together, no chemicals.
When your independent lab report comes back, it goes to Aidan, one of our owners and a water treatment specialist with over 30 years of hands-on experience. Because the testing is done by a third-party lab, the data is impartial. He reads your numbers, knows what matters for rotten egg smell (h2s), and gives you a clear recommendation for your situation.
You Get a Clear, Specific Recommendation
→ Whether this contaminant needs treatment, and how urgently
→ The exact equipment and size for your home, if any is needed
→ The correct installation order alongside anything else you treat
→ Estimated cost and what maintenance to expect
If Your Water Tests Clean, We Tell You That
We would rather earn your trust by being honest than sell you equipment you do not need. If your result comes back within safe limits, Aidan will tell you exactly that. No upselling, no fear tactics.
"I had my water tested and sent Aidan the results. Within hours he told me exactly what I needed: an iron filter and a neutralizer. After watching his YouTube videos I already trusted him. The recommendation was spot on and the system works perfectly." ★★★★★
Amber G., Verified Buyer
"I did two water tests at home and got inconsistent results. Called Aidan and he walked me through everything. Explained what the numbers meant, which ones mattered, and put together the right package for my house. No pressure, just honest advice." ★★★★★
Jerry S., Verified Buyer
"Water treatment is confusing. There's so much hype out there. I sent my test results to Mid Atlantic Water and Aidan cut through all the noise. Told me exactly what I needed, no more, no less. Been running the system for months now and the water is perfect." ★★★★★

Pinpoint the Rotten-Egg Smell. Then Remove It for Good.
Dissolved hydrogen sulfide and pH measured at an independent certified lab, plus a personal sulfur-filter recommendation from a 30-year well water expert.
The rotten-egg smell in well water is hydrogen sulfide gas, and it is one of the few contaminants you can detect with your nose but not size with it. Because it is a dissolved gas, it has to be captured with a preservation method and measured by a lab that knows how to handle it, which is exactly what this kit and the SimpleLab network provide.
You get the dissolved sulfide level plus pH from an independent, NELAC/ELAP-accredited lab. Sulfide tells you how strong the odor problem is; pH tells us how the oxidation and filter media will behave. Together they size the right sulfur filter and confirm whether a single air-injection iron/sulfur system can handle it.
Aidan reviews both numbers and recommends the exact system, or, if the smell is only on the hot side, points you to the much cheaper water-heater fix instead. Honest answers first, the right system second.

Frequently Asked Questions
You can tell something is wrong, but not how bad or how to treat it. Hydrogen sulfide is detectable by smell at extremely low levels, so the nose confirms presence but not the dissolved concentration. Sizing a sulfur filter and choosing the oxidation method requires the actual number plus pH, which this lab test provides.
A smell only on the hot side often points to a reaction in the water heater anode rod rather than sulfide in the source water, and that has a different, simpler fix. A smell on both hot and cold points to hydrogen sulfide in the well water itself, which is what this test measures and what a whole-house sulfur filter addresses. The result tells us which situation you are in.
Often yes. Air-injection Katalox-Light filters oxidize and remove both iron and hydrogen sulfide in one system, which is why many wells with both problems use a single iron/sulfur filter. The H2S level and pH from this test confirm whether that single system is enough or whether added oxidation is needed.
Aidan reviews your sulfide and pH numbers and recommends the exact sulfur (or combined iron/sulfur) filter and configuration for your water, then supports the install. If the smell turns out to be a water-heater issue rather than the source water, he will point you to the cheaper fix instead.
Absolutely. Call or text Aidan at 800-460-5810. He is available 7 days a week. If you are not sure whether you need this test, he can help you figure that out in a few minutes. No sales pitch, just straight answers. You can also email support@midatlanticwater.net.

The Cost of Guessing Wrong
A focused lab test vs thousands in wrong equipment.
What happens when you skip the test
Without a lab number, you are guessing. We have seen it hundreds of times: a homeowner buys the wrong system, or the wrong size, because staining or smell or scale looked a certain way. Wrong equipment means wasted money, an unsolved problem, and an eventual second purchase.
A focused lab test tells you exactly what is in your water so you buy the right equipment the first time. It is not a cost. It is insurance against a much larger mistake.

Why DIY Test Strips Can't Compare
+
DIY test strips test a handful of parameters with color-changing pads you match against a chart. They cannot detect contaminants at the low levels that matter for health, and they miss critical analytes entirely.
Our test uses the same certified-lab method state and federal drinking-water programs use: Dissolved sulfide (field-preserved) plus pH. The difference between a strip and a certified lab is the difference between guessing and knowing.
