The Oregon Health Authority has issued a warning to residents of an Oregon neighborhood after it was found that dioxin contamination in the soil of some yards. The contamination is thought to have been caused by a wood creosoting factory owned by J.H. Baxter, which was shuttered last year after increasing criticism and state and federal fines for chemical mishandling and emissions violations. The state is now conducting further testing on contaminated sites and plans to remove polluted earth this summer.
