Chemical leftovers from Humboldt County’s once booming timber
industry could create costly delays for two Arcata projects near its
marsh and wildlife sanctuary.
One project seeks to construct a dog
park at the old Little Lake Industries lumber mill site on South I
Street. The other would reuse dredged soils from the bay to create a
buffer to protect city properties from sea level rise.
However,
recent tests of Humboldt Bay sediment along the marsh found a “hot spot”
of harmful compounds known as dioxins, according to Humboldt Baykeeper
Director Jennifer Kalt. Dioxins are found in a wood preservative once
used by many of the nearly 100 mill sites near Humboldt Bay, which had
either spilled or had been dumped into the bay over the decades, Kalt
said.
“It was so toxic that it was restricted in the late 1980s,” Kalt said. “It’s only allowed now to be used on power poles.”
