Bubbling Crude

This “bubbling crude” could be from an episode of ” The Beverly Hillbillies”, but it isn’t. This is oil from a leaking underground storage tank we found on a Superfund cleanup project.

This is an excellent example of a boot wash station that we used on a Superfund site seven years ago. We entered from the top right, cleaned the loose mud off of our boots. Next, we stepped into the center bin and cleaned everything off of the boots. Lastly, we stepped into the closest bin and rinsed off.

Dude, Where’s My Tire?

Dude, where’s my tire? The driver had just left the Superfind site with a load of Subtitle D soil. He should have checked his nuts before he left.

We were working on a Superfund site one cold December night. It started to snow and things got slippery. We knocked off early.

Temporary Boot Wash

We were excavating a riverbank next to a former Superfund cleanup site and we hit a layer of black soil. I stopped the work and called out an Environmental Agent (EA). The EA took samples of the soil and sent them to a lab for analysis. I had the contractor rope off the area and build a temporary boot wash at the site entrance. It turned out the soil was clean.

Superfund Riverbank Cleanup

We started this superfund riverbank cleanup in 2013, finishing in early 2015. The project involved removing over 40,000 cubic yards of PCB-contaminated soil.

The project was in the inter-tidal zone; the contractor maintained vertical and horizontal separation between the excavation the the tide level.

Undercover Construction Inspector Vehicle

This undercover construction inspector vehicle was my daily driver for several years, a 1988 Volvo 240 with over 300,000 miles on it. I sold it to an musician a few years ago. Angelina Villalobos painted it in South Park, Washington.
