Rain moves through buried waste and comes out carrying PFAS. Municipal wastewater plants were never designed to remove it. New York proposes making landfills do it on site.

Certified compostable packaging is engineered to break down in a hot industrial windrow. Put it in a garden bin, a recycling bin or a landfill and it behaves like ordinary plastic — because in those conditions, it is.

Orbital spectrometers have found large landfill methane plumes that operators reported as far smaller. The measurement gap is now well documented; the enforcement and engineering response is not.
