Analysis

Vanadium in Tennessee: what the data shows

Tennessee has 89 cities with vanadium data from the EPA's UCMR 3 program (2013–2015). Vanadium was detected above the 21 µg/L EPA short-term health advisory in 0 of those cities. The state average max detected level is 0.51 µg/L. Vanadium occurs naturally in groundwater, particularly in the western United States where it leaches from volcanic rock and oil shale formations. Industrial sources include steel manufacturing, oil refining, and fossil fuel combustion. There is no federal MCL for vanadium — the EPA established a short-term health advisory of 21 µg/L for a 10 kg child consuming 1 L/day for 10 days. Long-term exposure to elevated vanadium has been associated with kidney effects in animal studies and possible developmental impacts. Reverse osmosis and ion exchange systems are effective at removing vanadium from drinking water.

FAQ

Frequently asked questions about vanadium in Tennessee

Is vanadium in Tennessee tap water harmful?

Vanadium has no federal MCL. The EPA short-term health advisory is 21 µg/L. No cities in Tennessee exceed the EPA short-term health advisory. Long-term exposure has been linked to kidney effects in animal studies. Vanadium is most common in groundwater in the western US.

How can I remove vanadium from my drinking water?

Reverse osmosis (RO) systems are highly effective at removing vanadium, typically reducing it by 90% or more. Ion exchange systems also work. Standard activated carbon filters are not effective against vanadium. If your water comes from a private well in the western US, consider testing for vanadium.
