A previous post shared details about the excavation of soils contaminated with high levels of PCBs, from October 6-9, 2015, along the bike path between Madison Kipp Corporation and the Goodman Center.
Here’s what the excavation looked like…enjoy! (sorry about the strange sizes, we had some formatting problems…)
Excavation begins, October 6, on the east end of the raingarden…
Earth First Advanced Waste drops off a PCB dumpster across from the splash pad…(Yes, Earth First came to Kipp!!)
The bike path is a busy place! Neighbors sit at the splash pad bench and enjoy the show…
Children pick vegetables near the excavation (red PCB dumpster behind them)…
A neighborhood mom whose children are playing at Goodman tells Earth First Advanced Waste they are “killing the earth” and does a ritual to “take the land back” and “release the bad energy” …
A dust monitor is in place (good step in the right direction….but is this monitor to assess dust exposures to the excavation workers? Or people on the bike path? Either way, it seems to be the wrong kind of monitor and in the wrong place….).
Dust barriers put up on 2nd day of excavation (Good, finally!! But won’t some fine dust go up and over them? )
A “Best Waste Solutions” truck behind the excavation spews smoke (oops!)…
Are there really no PCBs on the right side of this fence, next to the bike path?? This area has not been tested. Hmmm…..
Yellow “caution” tape was put up around dust barriers on October 8
The dust monitor concentration on the outside of the excavation dust fence read 19 µg/m3 at 10 am on October 8 (time-weighted average of 12 µg/m3)…
Soils with the highest PCB levels, along about an 80 foot stretch across from splash pad, were excavated right to the edge of the bike path, including the jogging path…
A couple hotspots in the raingarden, excavated on October 6, were re-seeded and covered with hay…
A PCB hotspot in the grassy area along the far eastern end of the bike path was “capped” with a few inches of clean soil (and later fenced off)…
