- Abstract
- Lead and strontium concentrations and isotopic compositions of surface water samples collected across the state of North Carolina have been evaluated to determine the predominate contributor of each element to the water. Strontium isotope systematics in NC surface waters are reflective of the underlying bedrock geology and the influence of seawater in the Coastal Plain. The lead isotopic data is decoupled from the strontium data and displays no trends with relation to bedrock geology, though there may be some evidence of natural lead contribution to river waters in the Blue Ridge Belt. Most lead isotope ratios fall within or very close to the range for eastern U.S. leaded gasoline, suggesting that the source of lead in North Carolina surface waters is primarily anthropogenic.
