Is there a ritual or spell to cleanse an area?

I know that plant growth can enrich an area, but can anyone think of a spell or ritual that will let you cleanse an area?

I’m thinking things like an area is diseased, or there’s some kind of poison, or maybe some kind of necromantic corruption. I haven’t come across anything in the mechanics for cleansing something like this, at best it would be something more cinematic.
