You know where landfill ends up in when not properly sealed? Groundwater and rain runoff. Drinking partially degraded plastic is not exactly neutral to health

You know where landfill ends up in when not properly sealed? Groundwater and rain runoff. Drinking partially degraded plastic is not exactly neutral to health. Poisoning wildlife with the added colorings or plastics themselves, neither. Especially insidious are plastic fibres - partially synthetic textiles. These should all be burned clean at very high temperatures first. Litter is easy to remove and even burn, micrometer level plastic dust is not. Standard water treatment at best can sediment some kinds of microplastics but not all. The cutoff levels that are safe for health for some plastics are miniscule for chronic intake. (Urethanes especially - kidney toxicity and cancer, probably others too. BPA is a joke compared to base PET stock at micrometers chronically.)

  Water runoff and sludge from landfills is treated, however only final very time consuming steps of biological sedimentation and treatment can remove most of them. Or very fine reverse osmosis or treatment with micron level filters, very energy intensive. So they do tend to end up in clean drinking water. There are many sources and no norms. Sometimes even metals bordering on norms can be detected near landfills. Sample efficiency ranges: https://www.sciencedirect.com/science/article/abs/pii/S0043135418310686 https://www.sciencedirect.com/science/article/abs/pii/S00431... I had a link with site in Sweden barely keeping norms for lead and cobalt... due to organic decomposition and incomplete runoff collection. Bad enough that I wouldn't build a well within some 10 km radius. Read up on what happens to all this thing called leachate. This is a main reason why European Commission wants the landfills to remain as exception.

  > And realistically, are landfills in the US and Europe leaking or not? Yes, they are. See https://pubs.usgs.gov/fs/fs-040-03/ https://pubs.usgs.gov/fs/fs-040-03/. A key quote: > The USEPA has concluded that all landfills eventually will leak into the environment We can minimize the amount of material that leaks, but it seems that all landfills will eventually leak at least some of their contents.

  Landfills are funded by the public. Public money has to be spent to fix problems caused by private companies. Is that not a problem?
