Studies have shown that chloride levels are rising nationally in groundwater since the 1990s because of road salt, said Mike Ekberg of the Miami Valley Conservancy District.
“It tends to stay down there a lot longer,” he said.
That said, the chloride levels in local water are starting to go down after last week’s storms, although the spike in the Miami Valley aren’t enough to be toxic to aquatic life in the rivers, Ekberg said.
Even so, well owners should test their water regularly, he said.
