I found old railroad ties for sale this month at the website of one of the 'big box' national home center chains not modern 'imitations' either—"old railroad ties". If you see old railroad ties for sale, report the seller to the EPA; and warn your friends not to buy them.
They can have the wood and soil tested for arsenic, creosote, chromium and other worrisome wood preservatives, but the tests can be expensive, and the odds are so strong that old wood was toxic that I would just cut to the chase and spend the money on safe removal, following the EPA guidelines for old railroad ties: Don't touch the wood with bare skin; don't let animals or children near it; don't let it get near a water supply; don't inhale the dust; wear protective equipment when you handle it—including gloves that are "chemically impervious"; and don't burn it—the fumes can be deadly.
Now: Back when I was younger, I might have felt comfortable doing this kind of removal work myself. But I am no longer younger; and I have become, as my Pennsylvania Dutch neighbors like to say, "Too soon old; too late smart", which means I now realize that I might have been tempted to cut corners back in my youth thanks to the invincibility felt by all men previous to their third or fourth decade on this planet.
IF they get that far. Older, and thankfully, wiser there was honestly only one direction to go in I now realize that the cost of buying the right kind of protective gear would probably be close to the same as paying professionals to do it. So today, I would get bids from several local companies that do asbestos removal—they already have the expertise, the right protective equipment, and perhaps of equal importance: access to safe disposal options—and get pros to do it.
Have them remove all the rotting wood and the top inch of soil. Then the homeowner or a landscaper —wearing long sleeves, protective gloves and a heavy duty dust mask—can have soil brought in to level the area, lay cardboard over the soil, frame out raised beds , drop them on top of the cardboard and fill them with topsoil, compost and perlite as discussed at length in our previous Questions of the week on raised beds—found under the letter R.
You can use non-dyed wood chips or bark mulch to cover the two-foot-wide walking lanes between the beds, but nothing weirdly colored or bad smelling. Then you'll be growing in clean soil for sure. And there won't be contaminated soil or sawdust blowing around for people to inhale or otherwise come into contact with. As we've stressed in the past, the big danger with treated wood comes from inhaling the toxins and absorbing them through your skin—so "just growing ornamentals there" as opposed to food crops isn't a safe option.
Do it right; you'll sleep better at night, and you'll also get highly productive garden beds out of the deal. You can even take your time and build a few of the new raised beds every season—my 'go slow' approach for people who have just moved into a new place.
But that's just for building the new beds. I'd want all the old wood and that top inch of soil out of there right away. These two materials come from waste tires and recycled plastics, which are very beneficial to environmental protection. This kind of plastic railroad ties absorb the advantages of wooden sleeper , steel sleeper and concrete sleeper, upgrade and optimize them, so that the composite sleeper has a stronger technical advantage. It will be an irreversible trend for plastic railroad ties to be widely used in the world.
