What each game says about it, in the games' own words.

Silver / SoulSilverWherever GRIMER has passed, so many germs are left behind that no plants will ever grow again.
CrystalWhen two of these POKéMON's bodies are combined together, new poisons are created.
RubyGRIMER’s sludgy and rubbery body can be forced through any opening, however small it may be. This POKéMON enters sewer pipes to drink filthy wastewater.
SapphireGRIMER emerged from the sludge that settled on a polluted seabed. This POKéMON loves anything filthy. It constantly leaks a horribly germ- infested fluid from all over its body.
EmeraldBorn from polluted sludge in the sea, GRIMER’s favorite food is anything filthy. They feed on wastewater pumped out from factories.
FireRedSludge exposed to X rays from the moon transformed into GRIMER. It loves feeding on filthy things.
LeafGreen / YAppears in filthy areas. It thrives by sucking up polluted sludge that is pumped out of factories.
Diamond / Pearl / Platinum / Black / WhiteIt was born when sludge in a dirty stream was exposed to the moon’s X-rays. It appears among filth.

Official data here is present-day reference data from PokéAPI, not a snapshot of any one game's era — the Fairy type and hidden abilities arrived partway through the series, so a difference against an older game can belong to the series rather than to that ROM hack.
