Concrete affects groundwater? Sand more environmentally friendly?
Help - I'm going crazy. But I'm going to attach a greenhouse, it sometimes blows up to 23 m/s here and there's a lot of snow. The installers want to use XPS boards and fill with concrete. The greenhouse company only recommends sand. But then I started to worry, partly about styrofoam in the ground. Partly now about concrete. I read that concrete can affect the pH value, that chemicals can leach into the groundwater while the concrete is fresh, etc. I need a quick answer - because now I don't know if I want this anymore or if I should stop and just fill with soil, sand, and gravel instead. Because it feels like a very big project... And is sand as stable against frost and to keep a greenhouse in place? Sand should be more environmentally friendly and cheaper than XPS and concrete?
Plastic has its drawbacks. But concrete, I find it hard to see that it would be worse than limestone.
There are chemicals in concrete that leach into nature. Slowly. Then I think- it will be impossible to remove the concrete. It will forever be in the ground. Likewise the xps styrofoam. Does anyone have experience with any other insulation material? And using gravel and compacted sand instead of concrete?

I believe that concrete leaching is an extremely marginal problem. What is left in the ground when it is demolished is up to those who work with it then, nothing you can decide or control now.
Worry about other things. For example, PFAS/TFA, even though it's even harder to do something about as a private individual.

I doubt that a greenhouse will remain standing after 1-2 winters in a location as weather-exposed as you describe unless it is properly anchored in concrete.
By the way, I have a cast foundation for the greenhouse (where we then built up with lecablock) and I have never seen any deposits or impact on the vegetation. Sounds very far-fetched.
If one day you want to tear it down, you can dig up everything including the plastic?

Can I get PFAS in the water from concrete?
