Originally Published by Earth & Climate News — ScienceDailyAquifer thermal energy storage (ATES) is more than a renewable energy source. The storage and extraction of heat and cold can remediate polluted groundwater ten times faster than existing technologies, a researcher says. Topic: Water

Protecting lakes, streams by removing phosphates as well as nitrates

RustandSteel

Originally Published by Earth & Climate News — ScienceDaily A low-cost method of removing phosphates from tile drainage water has been developed, and may help protect lakes and streams. Using steel byproducts to trap phosphates in simulated tile drainage water, the researchers envision installing a steel-containing cartridge as an add-on to nitrate-capturing bioreactors.

How rivers regulate global carbon cycle

CarbonRiver
Originally Published by Earth & Climate News — ScienceDailyRiver transport of carbon to the ocean is not on a scale that will solve our carbon dioxide problem, but we haven’t known how much carbon the world’s rivers routinely flush into the ocean, until now. Scientists calculated the first direct estimate of how much and in […]
