This one caught my eye also. I think the software analogy is not especially good, but it feels like there's some poorly-aligned incentives in landfill engineering. The point of landfills is to make trash invisible, so saving money by hiding engineering faults in the landfill itself is easy, they get buried along with the trash, and by the time the leakage becomes noticeable, the builder is long gone (bankrupt, merged/acquired, whatever), and the community is left to spend more on remediation than would have been required for prevention. The solution to this sort of problem is generally regulation and oversight. I try not to be cynical about the utility of that approach, but it's hard. The difference from software engineering is that, for landfills, the specifications don't change on the fly, and the engineering best-practices to build them actually exist.
