After the foul-smelling poop train finally left the small Walker County town of Parrish, the much better-smelling Febreze van rolled in.

Febreze gave out free samples of its odor-eliminating products to residents of Parrish after a train carrying more than 200 shipping containers of sewer sludge sat on a rail yard in town for more than two months as the containers were hauled by trucks one-by-one to a landfill about 20 miles away.

Sewer sludge is the solid material left behind after modern wastewater treatment processes, and the foul-smelling sludge was being shipped from treatment plants in New York and New Jersey to an Alabama landfill for disposal.

Residents complained of the odors for weeks, comparing the smell to decomposing bodies, and some saying they could barely stand to be outside until the last of the containers was hauled away on April 17.

Febreze came in shortly after to provide at least some relief.

"At Febreze, we believe that no one should be immersed in stink and are confident that our lineup of odor-eliminating products could finally bring a breath of fresh air to the good people of Parrish," said Mandy Ciccarella, communications manager for Proctor and Gamble Home Care, which makes Febreze.

Febreze this week released a YouTube video that includes interviews with Parrish residents about the experience with the poop train, and reactions after getting free bottles and cans of Febreze.

"The running joke was when the poop train came that we just needed to drop Febreze on top of the train," one resident said in the video.

Febreze couldn't do that, but the company did apparently drive around town handing out free samples after the train left.

"The poop train brought the funk and Febreze came by to freshen us up," another resident said.
