Could Treated Sewage Be a Tool Against Sea-Level Rise? – abc News
Article Synopsis – For decades, geologists have known that extracting large amounts of water can cause the ground to sink over time, sometimes by dozens of feet. Pumping the water back in has slowed some of this land subsidence and even slightly boosted ground levels in some areas. In Virginia’s Hampton Roads region, slightly more than half the relative sea-level rise is caused by land subsidence that’s mostly due to humans pumping water out of the ground. The Hampton Roads Sanitation District wants to inject an initial million gallons a day during a pilot project in 2018.
While this is a good experiment, and could raise the land by a number of centimeters, this method has extremely limited applications in terms of solving the overall problem of rising sea level. To read the actual article click here.
