Since Baykeeper’s 2006 success in getting Humboldt Bay designated as impaired by dioxin, sampling for this long-lasting contaminant has become common for dredging, restoration, and development projects. One recent study has revealed a major dioxin hotspot in Humboldt Bay near the Arcata Marsh. The good news is that ongoing monitoring at a former lumber mill in Eureka has shown that the cleanup brought by Baykeeper’s legal action has been effective.
