Potomac Landfill Inc

Big landfill on Greentree Lane that handles a lot of the Northern Virginia/DC-area trash; used by contractors, commercial haulers, and residents making large drops. It’s the kind of place where trucks outnumber cars and you’ll see heavy equipment moving piles around. Located in Dumfries, this is a true final-disposal site where loads get weighed and buried.

Drive up to an entrance booth and get directed toward the inbound scale - tipping fees are charged by weight, so expect to stop twice if you’re in a vehicle that has to be weighed leaving as well. The site is large and noisy: compactors and dozers are visible from most points, and open cells or capped areas are common. Loads are hauled to an active cell for dumping, then covered; there’s often a steady flow of commercial trucks alongside pickup trucks with household debris. Lines stack up on weekends and during seasonal cleanups, so there can be some waiting before reaching the scale or the tipping area.
