Dihydrogen Monoxide (DHMO) is a colorless and odorless chemical compound, also referred to by some as Dihydrogen Oxide, Hydrogen Hydroxide, Hydronium Hydroxide, or simply Hydric acid.
Once properly identified hazardous property is accepted for turn-in by a DRMO, DRMS pays for any costs associated with Notices of Violation (NOVs) and cleanup borne by the generator.
