Faculty note: Luczaj article


Geoscience Prof. John Luczaj (Natural and Applied Sciences) is a co-author on an article published recently in the journal Resources. The article evaluates the changes to groundwater quality in Northeastern Wisconsin that resulted from the 2007 Karst Task Force report and subsequent regulatory changes in certain counties. Lead author Kevin Erb is a graduate of UWGB’s Environmental Science and Policy graduate program.

Student earns state AWRA honor for ‘Best Undergraduate Student Poster’

The Wisconsin Section of the American Water Resources Association has honored UW-Green Bay student and Geoscience major Christa Kananen. She was given the best undergraduate student poster award last week for her research project on groundwater levels in the deep sandstone aquifer of Marinette County. Her poster (with co-author Prof. John Luczaj of Geoscience) was titled: “Drawdown of the Potentiometric Surface in the Cambrian-Ordovician Aquifer in Marinette County, Wisconsin” The award will eventually be posted at http://state.awra.org/wisconsin/studentposteraward.html.

Senior earns Sager award for work on Marinette County aquifer


The winner of this year’s Sager Scholarship is Christa Kananen, a senior majoring in Geoscience with a minor in Environmental Science. Her paper “Drawdown of the Potentiometric Surface of the Cambrian-Ordovician Aquifer in Marinette County” was based on her undergraduate research project under the guidance of NAS Associate Prof. John Luczaj. The Sager Scholarship for Scientific Writing was established by retired UW-Green Bay faculty members Paul and Dorothea Sager in memory of Chancellor Emeritus Edward Weidner and his commitment to UW-Green Bay and the Cofrin Arboretum. The $1,000 scholarship is awarded to a UW-Green Bay undergraduate who has demonstrated excellence in scientific writing resulting from a classroom or extracurricular academic activity. Students receiving honorable mention for this year’s competition were Reed Heintzkill, Courtney Pagenkopf, Holly Plamann, Alex Stenner and Timothy Zietz.

Luczaj says groundwater conditions could be factor with I-43 bridge

John Luczaj, associate professor of Natural and Applied Sciences and chair of UW-Green Bay’s Geoscience program, has granted numerous interviews to local reporters as they try to make sense of the Leo Frigo Bridge closure for their readers, viewers and listeners. Luczaj is an authority on the bedrock and soils of Brown County, having completed the first comprehensive bedrock map of the county for the Wisconsin Geologic Survey.

In a lengthy article in the Oct. 13 edition of the Green Bay Press-Gazette, Luczaj is one of the scientists and engineers quoted as to why Pier 22, one of the massive concrete pillars supporting the I-43 bridge, slipped two feet into the ground. Although state highway officials say the most likely explanation is shallow-layer corrosion of steel beams caused by fly ash, organic material and industrial waste used to fill the wetlands decades ago, Luczaj and at least one other expert say the cause might lie much deeper. Because the steel pilings below the pier don’t reach bedrock, approximately 130 feet below, they would be resting on a layer of clay or sand. Luczaj notes that the local water table has risen rapidly and dramatically since Green Bay suburbs deactivated most of their municipal wells and began piping Lake Michigan water from Manitowoc. That change in the aquifer could have greatly altered the stability of the soil layer, he says. It’s another theory, and an interesting one, as the investigation continues and the DOT evaluates bridge supports to determine how soon that section of the mile-long, 120-foot high harbor bridge can be repaired.

Comet watchers need scopes, sharp eyes

Retired Geosciences Prof Steve Dutch sends us this photo taken Wednesday night (March 13) from the campus bayshore near Lambeau Cottage. See the Comet PANSTARRS? In this image the comet is faintly visible about one-third of the way down the image, almost directly above the bright light at bottom. (This view is looking back toward the mouth of the Fox River and the Pulliam Plant emissions stack.) Dutch said that by early the week of March 18, the comet will be slowly moving north (right, in the photo) and higher from the horizon, but probably also fainter. He said it should be easy to see in binoculars and maybe with the unaided eye from a very dark location.
National Public Radio carried a report over the weekend on the comet. Click here.

Bedrock work uncovers new info, ancient faults

Geoscience Prof. John Luczaj is the man responsible for the first comprehensive map of Brown County’s bedrock, part of a statewide project commissioned by the State of Wisconsin and the U.S. Geologic Survey.

The resultant map should be of value to citizens concerned about bacterial contamination in shallow wells; to those who mine crushed stone; and to land-use planners considering aquifer issues, groundwater recharge, and the potential for water and pollutants to travel comparatively quickly through fractured bedrock.

“There are a number of people who need to know about the subsurface: People who are putting in utilities like water pipelines or gas pipelines, they need to know how deep it is to bedrock. People who are operating quarries, they want to know where resources are. People who are trying to figure our groundwater resources and how groundwater contaminates might move. If you don’t understand the subsurface geology you’re not going to have a handle on what those groundwater characteristics look like, how the groundwater is going to move,” Luczaj says.

Luczaj (pronounced LOOCH-eye) and his team inspected outcrops and quarries, core samples from drilling, and well-construction reports. His grant also allowed for a visit by a heavy-duty, earth-shaking “vibra” truck — perhaps the first seismic testing of its kind in Wisconsin, Luczaj says.

The in-ground sonogram helped confirm the existence of long-suspected faults — no longer active and likely millions of years old — in the sedimentary rock that underlies much of Brown County.

Despite roughly 100 feet of vertical displacement, the plates are entirely stable and of direct interest only to groundwater researchers… and, indirectly, to Packers fans, as a curiosity. One of the faults, several hundred feet deep, is believed to run in the general vicinity of Lambeau Field.

Luczaj’s research team included geologists and GIS/database specialists, as well as UW-Green Bay students. The project, more than two years in the making, was supported by $250,000 in grants from the US. Geologic Survey and the UW-Extension state survey, known as the Wisconsin Geological and Natural History Survey.

Luczaj joined the UW-Green Bay faculty in 2005. He was previously a senior scientist and data manager with American Hydrogeology Corp. He holds a Ph.D. and master’s in geology from Johns Hopkins University in addition to a master’s from the University of Kansas and a bachelor’s from UW-Oshkosh.

His mapping project began in the eastern half of Brown County, where relatively less was known about the stratigraphy of sedimentary rocks that are up to nearly 1,500 feet thick in places, and where few wells are deep enough to approach the pre-Cambrian “basement.” The second-year investigation centered mainly on western parts of the county.

Dutch talk (in NAS seminar) begins at 3:30 p.m.

Geoscience Prof. Steve Dutch will deliver the final NAS Seminar Series presentation for the semester Friday, May 4, offering thoughts on technology, change and progress through his lecture “How the West Dominated Technology or What I Learned From My General Ed Course.” The event kicks off with a 3 p.m. social in ES 317, which will be followed by Dutch’s talk from 3:30-4:30 in ES 328. The series is sponsored by the Office of the Provost and Institute for Research.
