Permeable pavement sounds interesting, and I wonder how safe it is (the bottom of the fractional-distillation barrel might have fewer volatiles but do we want more surface area of the stuff to come into contact with water?) and how quickly it gets clogged.
Also, beavers: they're great at slowing the flow of water across a landscape, giving the water time to recharge aquifers. We'll need to address how we use land, though, to make room for these engineers to do their thing.
- dylan604 3y agoMy concern for urban permeable pavement is all of the chemicals that would be absorbed with it. Same with the forced injection of water back into an aquifer. I was under the impression that the water being pulled through the ground is a filtering process so that the water in the aquifer is clean.
- myshpa 3y ago> the water ... filtering process ... the water in the aquifer is clean Clean(er) ... maybe ... nowadays nitrates, pesticides/herbicides, pfas/pfoas, industrial chemicals (solvents, heavy metals, volatile organic compounds), pharmaceuticals (prescription drugs, over-the-counter medications), lead, arsenic, mercury, and cadmium (through industrial activities, mining operations, and improper waste disposal), chlorinated solvents, such as trichloroethylene (TCE) and perchloroethylene (PCE), all were detected in the groundwater. Nothing is "clean" anymore. Not the arctic, not the tops of the mountains in the natural reserves, not the remote islands, not the deep underground.
