I am Robert M. Powell. My degrees are in Zoology and Environmental Science, with a lot of chemistry courses thrown in, which was fortunate because almost all my professional work has involved extremely detailed chemistry, including some chemical reactions in experiments that hadn't been described before. I’m also a consultant, so get in touch if my expertise matches your needs.
I currently teach environmental science courses at three colleges. I had a very long career prior to becoming a professor, with over 40 years of experience. Here are some highlights:
- Two years as a senior technician in a genetics research lab.
- Eleven years at the Oklahoma Geological Survey (OGS) as an Analytical Chemist.
- Eleven years as a Researcher at USEPA's National Risk Management Research Laboratory, Ada, OK.
- Twenty-four years as an environmental consultant via Powell & Associates Science Services.
- Seven years+ (so far) as a professor at three colleges.
My expertise includes aqueous chemistry, ground water geochemistry, contaminant remediation using permeable reactive barriers (PRBs) in the subsurface and other innovative in situ treatment technologies, ground water sampling, site characterization, contaminant transport and fate, including colloidal contaminant transport, analytical chemistry, exploratory data analysis, risk assessment, technical writing and editing, and providing expert witness support for clients on a variety of environmental topics under litigation. One of my fascinations is sorting out complex data using exploratory data analysis software.
At the OGS I analyzed large numbers of environmental samples, including rocks, coal, surface water, ground water, water from deep sea sediments, uranium levels in ore, and so on; I programmed computers to do the calculations.
At EPA, my emphasis was in surface water and subsurface systems including soil, the unsaturated zone above the aquifers, and ground water, including the transport of contaminants adsorbed onto colloidal particles and as chelates. I was involved in the research and development of low-flow rate and passive purging and sampling of groundwater monitoring wells. I also worked on the development and understanding of the geochemical mechanisms, reaction rates, costs and approaches to in situ contaminant remediation using permeable reactive barrier technology, authoring many reports and peer-reviewed papers in the process. Both these methods are now being used worldwide, for which I get nothing because my work was government-funded, LOL.
As a consultant I have had numerous clients from industry, legal teams, Native American tribes, other consultancies, and government, both local and federal. One of my favorite projects was serving as a member of the six-person External Advisory Group for the Hydrogeologic Workplan at the Los Alamos National Laboratory for seven years; I got to go to New Mexico at least twice per year and I love it there, both the scenery and the stupendously good Mexican food.
About three years ago, I was subcontracted to Michigan Technological University for the State of Michigan. Michigan Tech was contracted to develop a worst-case scenario risk assessment for the Mackinac Straits Line 5 pipelines owned by Enbridge, Inc., should they rupture and release large amounts of oil. I worked on the ecosystems part of the risk assessment.
I've authored 40+ publications, book chapters, and encyclopedia articles and lost count of my professional presentations at around 50 or so.

Can you publish an #rstats package anywhere which has reasonable visibility in #ecology or #climatology journals without paying $2500?
Seems like Methods in Ecology and Evolution went #OpenAccess (meaning it isn't for those on a small budget - and want to publish).

If you’re feeling #overwhelmed and anxious today because the defining #crisis of our generation #climatechange is looking dire and #politicians seem unwilling to take the drastic measures we need, it is ok to stay off social media today. Maybe put a note in you calendar to call your elected representatives later this week and tell them it’s time to take the #climatecrisis seriously. No more #subsidies for the industries driving emissions up. #DasguptaReview #ipcc

The upward redistribution of wealth over the past 40 years has shifted $50 trillion from the bottom 90% to the top 1%. That’s $50 trillion that would have gone into the paychecks of working Americans.
The greatest trick of all is trickle-down economics.
Another Republican hypocrite, but I’m being redundant.

@zleap @freemo @trinsec @boris_steipe Them talking together is how they get caught up in self reinforcing loops that radicalize them further, convince themselves of their righteousness, and organize to take malicious actions.

Yesterday, Freedom Caucus Republicans sent a letter to Pete Buttigieg at the Dept of Transportation demanding National Transportation Safety Board documents related to the train disaster in East Palestine.
Buttigieg responded with shock because
NTSB is an independent body, for good reason, and not even part of his Department.
Republicans don’t even know what they’re doing.
Regarding the train derailment in Ohio and the shipment of contaminated soil to Michigan for treatment…Vinyl Chloride (VC) is a highly volatile and carcinogenic chemical. If it was actually in the soil that was being transported it would have been getting released to the atmosphere during the entire transport unless it was entirely sealed up, which it probably wasn’t. Every transfer of the material would release more VC into the atmosphere. The article mentions washing with water and allowing the contaminant to evaporate. It’s VC, it is going to evaporate whether it is in water or not. The only way to treat something like this is by incineration at the site of the spill or using microbes or chemical reactions to break it down in tanks, again on site. They make equipment for such onsite treatment. One shouldn’t be hauling it all over the place.

Today is the Day of Remembrance for the Japanese American community. 81 years ago today, when I was just a boy of four, FDR signed Executive Order 9066, setting in motion the evacuation of people of Japanese descent from the West Coast and our long years of internment inside ten barbed wire prison camps.
We must never let such a thing happen again in America, and and we must strive everywhere to prevent the forced relocation and mass incarceration of innocent people. #NeverForget #NeverAgain

"People coming from Twitter tend to think of the fediverse as a Twitter-replacement for the obvious reasons, and thus use Mastodon (or perhaps micro.blog), but that’s only a fraction of its potential. The question isn’t if the fediverse can replace Twitter, but if protocols can usurp platforms in our life online. With enough momentum the fediverse can be the fabric of the social web, incorporating existing systems like Tumblr and Medium and outright replacing stragglers."

Special Counsel Jack Smith must be chuckling this morning following this development. It turns out someone in 45’s campaign in Wisconsin made recordings of a meeting held two days after the 2020 presidential election. Whoops! What they caught on tape, and what it means, in today’s piece. https://statuskuo.substack.com/p/lordy-there-are-yet-more-tapes?sd=pf

Let College Board know we are NOT okay with silencing these voices. Join me in taking a stand against Gov. DeSantis and others trying to limit our academic freedom: https://www.thepetitionsite.com/takeaction/109/795/945/?TAP=2430&source_id=US109795945

We all admire Amsterdam for having the vision to replace car infrastructure with bike infrastructure. We see the positive uplift in small business activity, and livability. 🙂👍🏿
Now imagine doing that in reverse. Replace relatively safely walkable and bikeable infrastructure with car infrastructure. In fact, put in freeways. Demolish entire thriving wealthy neighborhoods with freeways that don't serve the neighborhood.🙃
That's what we did to Black folk. That's how we destroyed Black wealth.

A 2s to 3 pz transition. Phase evolution is seen from the rotating frame in which the phase of the 2s orbital is held constant.
As you go up in principal quantum number for an orbital of a given type, the orbital gets an extra node. That's why in the 2s orbital you can see an internal node and an inversion of the phase (denoted by the color).

Humpback whales hunt/eat using a technique called “bubble net feeding.” They create walls of bubbles to capture fish in a virtual net before swallowing them up.
The result is absolutely stunning. Their style of eating is literally an art.
