The natural abundances of the stable isotopes of lead are used to identify natural and industrial sources of lead in the coastal waters of British Columbia, Canada. The 206Pb/207Pb ratios, used to characterize the lead source, had values of sim 1.24 for coastal oceanic water, sim 1.22 for fjord waters receiving lead from mine tailings, and sim 1.163 for waters near urban centers. The lead concentration data are in agreement with presently accepted seawater values.
