Road Salts Linked to High Sodium Levels in Tap Water

Sarah Stanley, Science Writer by Sarah Stanley 8 March 202227 August 2025

Use of deicing agents may sometimes raise sodium levels in drinking water beyond healthy limits for people on salt-restricted diets.

Lake Michigan’s Salinity Is on the Rise

by Robin Donovan 7 February 202227 March 2023

Road salt is primarily to blame for the shift, though the water remains within safe levels for now.

Atmospheric Turbulence May Promote Cloud Droplet Formation

by Morgan Rehnberg 18 March 20217 March 2022

Turbulence causes local variations in relative humidity, which can push particles past a critical saturation threshold for droplet nucleation.

Hurricanes Wakes Show Asymmetrical Response in Ocean Salinity

by J. Sprintall 21 January 20211 February 2023

It’s well known that hurricanes can substantially impact ocean surface temperature, but a new study shows they can also induce an ocean salinity response in unexpected ways.

Evaporation Reverses Groundwater Flow and Forms Hyper-Salinity

by D. Scott Mackay 4 December 20201 December 2022

A numerical model of groundwater-surface water systems shows how floodplain evaporation can reverse stream-groundwater flow and produce strong buoyancy changes associated with salinity.

Does Drinking Water Salinity Affect Child Mortality?

by Avner Vengosh 25 June 20206 February 2023

An association between drinking water salinity and neonatal and infant mortality in Bangladesh indicates the critical role of water salinity on child health.

Mmm, Salt—Europa’s Hidden Ocean May Contain the Table Variety

Katherine Kornei, Science Writer by Katherine Kornei 9 July 20197 March 2022

Hubble Space Telescope observations suggest that sodium chloride exists in young, geologically active regions on Europa, likely fed by upwelling from the moon’s subsurface ocean.

Chemical Patterns May Predict Stars That Host Giant Planets

Kimberly M. S. Cartier, News Writing and Production Intern for Eos.org by Kimberly M. S. Cartier 25 June 20197 March 2022

Stars with giant planets tend to have a few key elements in abundance. A new algorithm used these patterns to predict hundreds of stars that will likely have exoplanets if we go looking for them.
