Hydrogen Sulfide gives off a "rotten egg" odor, even in low amounts. Since it is a volatile gas, it needs to be tested on-sight for an accurate reading. To determine the proper equipment needed to effectively remove it, test your well water to find the level of hydrogen sulfide (H2S) that is present. This easy test will accurately detect levels of H2S up to 5 ppm. Contains enough for 18 tests.
