Order the kit, collect a sample, mail it back with the prepaid label, and get certified results in about 10 business days. Then a real expert tells you what your numbers mean and exactly what to do.\u003c\/p\u003e\n\n\u003ch3\u003eWhy Test for This\u003c\/h3\u003e\n\u003cp\u003eThat rotten-egg or sewer smell, strongest on the hot side or after the water sits, is almost always hydrogen sulfide gas (H2S). It tarnishes silverware, corrodes plumbing, and makes the whole house unpleasant. Because it is a dissolved gas, it can be tricky to capture in a sample, so it needs a kit designed to preserve it and a lab method built for it.\u003c\/p\u003e\n\u003cp\u003eThis test reports dissolved sulfide plus pH. Sulfide tells you how aggressive the odor problem is; pH tells us how the chosen oxidation and filter media will perform. Together they determine whether an air-injection iron\/sulfur filter is enough or whether additional oxidation is warranted, and how to size it.\u003c\/p\u003e\n\n\u003ch3\u003eWho This Test Is For\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eYour water smells like rotten eggs or sewer, especially when hot\u003c\/li\u003e\n\u003cli\u003eThe smell is worse after the water sits or first thing in the morning\u003c\/li\u003e\n\u003cli\u003eSilverware tarnishes or plumbing shows black staining\u003c\/li\u003e\n\u003cli\u003eYou want H2S and pH numbers to size a sulfur filter correctly\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat the Lab Measures\u003c\/h3\u003e\n\u003cp\u003eThis test reports 2 parameter(s) for rotten egg smell (h2s) using Dissolved sulfide (field-preserved) plus pH, at a NELAC\/ELAP-accredited laboratory. No federal limit (aesthetic). Humans smell H2S well below 0.5 mg\/L. Treatment design depends on the dissolved level and pH.\u003c\/p\u003e\n\n\u003ch3\u003eIndependent, Third-Party Lab Testing\u003c\/h3\u003e\n\u003cp\u003eWe do not test your water ourselves, and that is the point. Your sample is sent to one of over 200 NELAC\/ELAP-accredited laboratories across the United States, the same independent labs used by state health departments. The result is impartial, then we help you act on it.\u003c\/p\u003e\n\n\u003ch3\u003eWhat Fixes It\u003c\/h3\u003e\n\u003cp\u003eIf treatment is needed, the typical solution is \u003ca href=\"\/products\/iron-and-sulfur-filter-2510aio-fleck-1-5-cubic-foot-10-54-with-katalox-light\"\u003eIron \u0026amp; Sulfur Filters (Air Injection)\u003c\/a\u003e.

After your independent lab results come back, Aidan (one of our owners, 30+ years in water treatment) personally reviews your numbers and tells you whether you need treatment, exactly what equipment and size, the correct installation order, and what maintenance to expect. If your water is within safe limits, he will tell you that too.
