The Asarco smelter shutdown more than 30 years ago but the plant's legacy is still being felt. Lead and arsenic emitted from the smelter's smokestack contaminated the soil and found its way into local lakes. UW Tacoma Associate Professor Jim Gawel joins us to discuss his work. Gawel and a team of researchers is examining arsenic in local lakes including Lake Killarney in Federal Way. Gawel will also talk about the importance of getting students into the field and the chair in his office that's so nice no one will sit in it.
