Sewage spill in yard

[Kirk Pak]

Sewage spill after root ate into the main sewer line. Pipe replaced. Some leakage into crawl space - Most of it remediated, but going to check again. Still smells after a couple of months every time it rains or snows. Soil hasn’t had a stretch of dry weather for a while.

Got a dehumidifier for the crawlspace and about to install.

Has anybody tried lime treatment for the yard? If so, what’s the best way to go about it?

Thanks!
