85 companies across 17 environmental service categories. Free to search, free to be listed in, and honest about where the information came from.
Most entries started as desk research — public company websites, state and federal registries, permit and licence databases. That is why every listing shows a status and a date instead of implying we have audited anybody.
Your filters run first. Whatever survives them is what you see — every qualified company, whether or not it pays us. Within that filtered set, paid listings sort above free ones and are labelled as paid. Money changes the order of the companies that already matched. It never changes which companies matched.
If you would rather ignore the ordering entirely, tick the companies you care about and export the shortlist to CSV.
If a listing is inaccurate — yours or somebody else's — tell us and we will fix or remove it. Correcting a listing is free and does not require buying anything.
