During his presentation, Kent Udell talked more about thermal treatment methods. He expanded more on his earlier comments on how steam injection can be effective under certain circumstances and walked the group through the limitations around it.
He also talked about the positives and negatives of electrical heating and conductive heating. He concluded that he believes the best option for Wyckoff would be a combination of steam injection and conductive heating.
He cautioned that it would take a lot of energy to power this kind of remedy. And that means costs. Other sources besides hydropower could be wind or maybe even waves or tidal power. But perhaps a more realistic option could be biomass (wood, agricultural and yard waste) generated on the island.
Frank Kellogg of DCI Environmental Inc. in Savage, MN, brought us home. He advocated using a combination of removing and containing contaminated material to meet cleanup goals.
That’s it for today. On Wednesday, participants will meet in small groups to talk over specific ideas, then get back together for a large-group discussion.
At 7 p.m. Wednesday, a community meeting is scheduled at IslandWood. You can hear directly from and talk with the experts about the Wyckoff site.
You also can join in the discussion at www.twitter.com/wyckoffgen. Find the experts’ presentations here, under the entry for Jan. 12-14.
