Toxics in Wallowa Lake BMD1P.jpg

Divers from Blue Mountain Divers show a barrel found at the bottom of Wallowa Lake in August 2018. The divers contacted the Oregon Department of Environmental Quality and filed a report that included photographs and videos of one of the 55-gallon barrels, showing the label.

JOSEPH — It wasn't just an ordinary dive for Lisa Anderson and William Lambert, who always go looking for items in the bottom of Wallowa Lake. This one just happened to be a little different.

Anderson and Lambert, members of Blue Mountain Divers, a nonprofit scuba diving organization that seeks to find, recover, and preserve historic and archeological objects that are now at the bottoms of lakes and rivers, were scuba diving in the south end of Wallowa Lake near the marina in August 2018 where the water deepens abruptly. Working at depths of 50 to 120 feet, where the water deepens abruptly just north of the marina, they found a metal milk jug, and a couple of other odds and ends.

Then the duo saw the barrels.

They bore labels that said "2, 4-D or 2, 4, 5-T WEED KILLER."

“There were about 25, 55-gallon drums, and a dozen bigger 100-gallon barrels,” said Blue Mountain Divers member Lisa Anderson. “It looked as though they had been there for a while — 10, 20 years or more. The smaller drums were corroded, and whatever was in them had probably already leaked out. But the big ones were sturdier. They seemed to be intact.”

Lambert and Anderson ended their dive, and once home in Walla Walla, contacted the Oregon Department of Environmental Quality. The report the Blue Mountain Divers filed included photographs and videos of one of the 55-gallon barrels, showing the label.

Their report also noted that they did not know whether the barrels were full or empty, or how long they had been in the lake. But what alarmed them was that “the ingredients in 2,4-D and 2,4,5-T were nearly identical to the infamous Agent Orange, and also a known carcinogen,” Blue Mountain Divers said in their report.

Wallowa Lake is the primary source of drinking water for Joseph.

In their response to the Blue Mountain Divers’ complaint, Oregon DEQ noted “drums have been found at the lake bottom for years, a remnant of when empty drums were used extensively at the lake to anchor docks. It was common practice at the time for people to fill the drums with water, rocks or cement and anchor the drums with rope to floating docks. Drums were also commonly used to provide flotation to docks. Over the years, as the docks disintegrated or were removed or abandoned, many of the drums remained, especially those used as anchors.”

Nevertheless, DEQ coordinated with EPA in analyzing and resolving the problem. Although no pesticides or herbicides have been detected in Joseph’s drinking water, the fact that the drums were discovered in an area where nothing similar had been found before was a concern. EPA made the decision to remove the barrels from Wallowa Lake.

At the EPA’s request, Blue Mountain Divers will help them relocate the barrels so that commercial HazMat divers under contract to EPA could remove the barrels from Wallowa Lake. Later this month Blue Mountain Divers plans a dive to relocate what the EPA has termed “historic drums.”

“We are going to use negative buoyant cord, similar to that used in cave diving, to help them find the barrels,” Anderson said. “The negatively buoyant string won’t get snagged by fishing lines.”

“The EPA and DEQ are collaborating to develop a plan to recover the barrels — especially the larger, seemingly intact ones,” said Mike Boykin, project coordinator for DEQ.

The present idea is to remove the entire collection of barrels and drums in the fall — probably in late September or October, once tourism and lake use has subsided, and also when there is no conflict with fish spawning. They plan to engage an independent commercial dive contractor who would use fully suited divers to locate the subsurface containers, roll each of the 100-gallon barrels into a bigger drum, seal that larger container, and hoist it to the surface where it would be placed on a barge.

“Each of those bigger, sealed containers could weigh a half-ton or more,” Boykin said. “So the equipment needs to be up to the job. The barge can’t just be a rowboat. It has to be stable and sturdy.”

The plan, organizers said, is to treat all of the barrels as if they all contain hazardous material.

The project will likely take about a week. It is considered a “superfund” cleanup and will be funded by EPA under the Comprehensive Environmental Response, Compensation and Liability Act of 1980.

“We want to be sure everything stays clean, and we do this right,” Boykin said. “If the barrels are still full and they open up, the first thing that you’ll see is likely to be a fish kill. We don’t want to take any chances of that happening."
