I think the ordering of these goals is pretty interesting. It looks like they're more focused on societal and social issues compared to environmental issues; but, fortunately, it doesn't seem like the goals reflect the same thing. I would like to see more strenuous sanitation goals though. Halving untreated wastewater by 2030 doesn't say anything about their standards for "treated" wastewater. There's also basically nothing about improving the outdated wastewater treatment infrastructure that's in 1st and 2nd world countries. There really needs to be improved standards for wastewater facilities across the board. They do address it somewhat in the water resources section, especially by implicating nutrient pollution, but it still seems like a bit of a blind spot to me.
