Philly's Drinking Water Turns Salty After Snow Melts

The recent melting of snow and ice in the Philadelphia region is causing rock salt to enter the local drinking water supply, posing a potential concern for residents, especially those on salt-restricted diets. According to John Jackson, a senior scientist at Stroud Water Research Center, salt concentrations in local waterways have been doubling approximately every two decades.

This excess sodium chloride, chemically identical to table salt, is flowing into major water sources like the Schuylkill and Delaware rivers. Dr. Arthur Frank, an environmental health expert at Drexel University, highlighted that while not considered highly toxic, elevated sodium levels can strain kidneys, increase blood pressure, and add to cardiovascular risk. Consumers may detect a slightly salty taste in their tap water for a short period.
