Analyze your water for stinky hydrogen sulfide (H2S) gas with these DIY at-home test strips.
High levels of H2S are one of the most common explanations for the "rotten egg" smell in some drinking water. While hydrogen sulfide does not typically present a health risk in drinking supplies, it is a nuisance and inconvenience.
Important: These DIY at-home test strips should be ordered as an addition to a laboratory test kit. Results from lab testing are often very important towards making sense of self-testing kit results.
