Working During COVID
2020 and 2021 provided lots of opportunities to experience changes in the working world and in a professional organization. While many of these challenges have passed, others are ongoing and new ones are emerging. But not everything changed, as they say the show must go on and interesting projects were not put on hold because of COVID. One site investigation appeared routine from the outset, but once the data started coming in things were not what they seemed. Additional research was needed to potentially avoid a major construction redesign; and the results inspire some big questions.

Maddie German works as an environmental geologist outside of Atlanta, Georgia for Atlantic Coast Consulting. She primarily focuses on site assessment work, groundwater and subsurface investigations. She was formerly the Carolina's Chapter chair and has served on several AEG committees. When not working, she spends her time slowly walking her 2 senior dogs or riding the many mountain bike trails in the Georgia foothills.
Exchange of River Water with Offshore Groundwater in Calvert City, KY
A Superfund site is located near the end of the Tennessee River in Kentucky. There is contamination under the river in the 'river aquifer'. The water level in the river is very dynamic due to the seasonal variations over such a large catchment area and a dam immediately upstream. Will these river level fluctuations eventually restore the river aquifer, once the DNAPL is removed? A graphical and mathematical analysis answers this question.

Bench-Scale BioChemical Reactor Removes Selenium from Mineral Processing Effluent
Fazio, Thomas1 (presenter); Gusek, James J.2; White, Steve1; Renner, Jim1; Stanton, Dan1
Selenium is a trace constituent of sediments and ground water accessed for heavy mineral sands in southeast Georgia. Re-use of water to separate the desirable minerals concentrates dissolved constituents, necessitating a blowdown. pH adjustment and flocculation remove suspended humates and most metals, but selenium in the effluent exceeds the NPDES limit of 5 ppb. A bench-scale biochemical reactor has been operated for 2 years. Various recipes of organic materials and bacteria reduce soluble selenite and selenate to insoluble elemental selenium which precipitates in the reactor cell. Se concentration in the BCR discharge is consistently less than 5 ppb.

Georgia's Mining and Mineral Heritage
Gray, Julian C. 1
Georgia has a rich mineral heritage going back to the 1700s. The geology of Georgia encompasses a wide range of rocks from Precambrian basement rocks, Paleozoic sedimentary rocks, igneous rocks including granites and pegmatites, metamorphosed sedimentary and volcanic rock, and unconsolidated sediments. Each of these environments host interesting mineral deposits of interest to mining and mineral collectors. These resources have been exploited for aggregate and dimension stone for construction, industrial minerals such as ochre and kaolin for pigments and paper coatings, kyanite for ceramics, beryllium for steel making, and mica for the electronics industry. Metallic mineral resources historically recovered include gold, iron, copper, and manganese. Recently, minerals have been mined for their beauty as mineral specimens for the collector or for gemstones.

Working During COVID
Johnson, Calvin R. 1
As we emerge from about two of the weirdest years' our consulting careers, let's look back and reflect on what transpired from the initial announcement of a potential outbreak of something called COVID or the "China Flu" to national, state, and local lockdowns, school and business closures, and individual business operational changes over time. The global pandemic seemed to touch every corner of the globe and has impacted people, families, communities, businesses, and countries in ways that are likely to leave scars and may alter the way we work, interact, plan, and conduct business for the foreseeable future and possibly forever. But as they say, "the show must go on" so we adjust and adapt to continue to survive and make a living as technical professionals. Basically, we keep doing what we have been doing our whole career, although the rules seem to be changing more rapidly, thus further complicating our daily lives and schedules to a level that seems unimaginable only about two short years ago.
