I am not an ‘either/or’ person, but an ‘and’: wine & beer, cats & dogs, movies & books ... You get the idea

Software developer and amateur radio enthusiast. Antenna experimenter. Helper of herons and all birds. Obedient servant of a chihuahua.

Let's see: I've lived in 9 US states (Mass, NY, Pennsylvania, Washington DC, Virginia, Maryland, California, Arizona, Vermont) and England, Belgium, France, Israel, and Japan.

I used to be a news photographer in Washington DC during the Clinton years. I've worked for Congressional Quarterly, UPI, Scripps Howard News Service.

Now I live again in Paris.

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.

#Introduction

I live on the shores of #LakeSuperior on the #Keweenaw Peninsula in the #UpperPeninsula of #Michigan. This region is within Ojibwe Gichigami (“Ojibwa’s Great Sea”) homelands and ceded-territory, established by the TREATY OF 1842

I'm a professor of #environmental #chemistry with an interest in everything related to #climate, including molecular to global aspects of the carbon cycle, energy and social transitions, new and old technologies for sustainability, forests and biodiversity, local to international climate policy, and the systems thinking approaches we need to make progress.

Too much of a news and politics junkie than is healthy.

I share my homestead with a partner, a dog, several felines, two donkeys, plants, and occasional uninvited critters.
