Since the start of the year, I've seen a spat of deals in the Environmental Remediation & Abatement space (think Water Treatment, Asbetos/Lead Removal, etc.) - while i've been busy trying to wrap my head around this sector, I'm curious what others may have learned about how to exit in this industry. Seems like attractive margin profile from an owner/operator perspective - even at small scale - means that the industry remains fragmented. Additionally, it seems like the high prevalence of labor unions here has kept out larger PE.

Any experts out there?
