June 23, 2011: Sampling for Toxic Contamination in Puget Sound's Muddy Bottom
Can muddy waters provide answers to understanding what toxic contamination is polluting Puget Sound waters? Marine scientists with the Department of Ecology hope so. The scientists are engaged in a multi-year study to collect sediment or mud from the bottom of urban bays. Sampling in Elliott Bay and Commencement Bay found most contaminants come from storm run off. Some like lead are on the wane, while others like phthlates, the key ingredient added to plastic to make it flexible, remain steady. Green Acre Radio joined ecologists in South Puget Sound’s Oakland Bay and has our report.
