Dr. Karl Haase is the technical lead of the USGS Reston Groundwater Dating Lab, and a Research Chemist with the USGS Water Resources Mission Area.
I am a research chemist studying methods of groundwater age determination. I am generally interested in the relationships between atmospheric gases and groundwater, as mediated by the interactions in the vadose zone, the layer of the ground that water must pass through before it enters an aquifer.
I have a background in experimental atmospheric chemistry, having worked with several groups on topics including ocean fertilization, biogeochemical impacts to atmospheric chemistry, oceanic emissions of halocarbons to the atmosphere, instrument validation studies, long term observations, anthropogenic emissions, and air quality measurements.
Dissolved Gases are important chemical tracers in groundwater systems. They provide information about groundwater age, aquifer mixing, and the climate conditions when water entered the aquifer. This information can be used to study issue of groundwater availability, quality, and quantity. Additionally direct measurements of these properties can be used to validate groundwater model output and improve model algorithms, allowing more accurate assessment of aquifer systems. I have designed, constructed several noble gas mass spectrometer and GC systems to measure dissolved fixed gases (O2, N2, He, Ne, Ar, Kr, and Xe) to assess groundwater recharge temperatures more accurately, and I am studying the behavior of various anthropogenic compounds in the groundwater system.
In pursuit of these research goals, I have developed novel and customized analytical systems and sensors for research and production operations. Among others, these include an automated economical quadruple mass spectrometer based noble gas analyzer, a dual channel GC-FID-AED system for measuring trace hydrofluorocarbons (as novel groundwater age tracers) and trace hydrocarbons (to better understand hydrocarbon geochemistry, a highly automated multi-port noble gas analyzer for tritium-helium dating and noble gas concentrations in groundwater, a self contained low cost pCO2 sensor, and GC-TCD system for measurements of He/Ne in groundwater samples.

Coal mining has been the dominant industry and land use in West Virginia’s southern coal fields since the mid-1800s.

Acetylene (IUPAC name: ethyne) is a colorless, gaseous hydrocarbon, composed of two triple bonded carbon atoms attached to hydrogens (C2H2). When microbiologists and biogeochemists think of acetylene, they immediately think of its use as an inhibitory compound of certain microbial processes and a tracer for nitrogen fixation. However, what is less widely known is that anaerobic and aerobic microorAuthorsDenise M. Akob, John M. Sutton, Janna L. Fierst, Karl B. Haase, Shaun Baesman, George Luther, Laurence G.

Acetylene (C2H2) is a trace constituent of the present Earth's oxidizing atmosphere, reflecting a mixture of terrestrial and marine emissions from anthropogenic, biomass-burning, and unidentified biogenic sources. Fermentation of acetylene was serendipitously discovered during C2H2 block assays of N2O reductase, and Pelobacter acetylenicus was shown to grow on C2H2 via acetylene hydratase (AH).

A method is presented for using dissolved CFCs or SF6 to estimate the apparent age of stream base flow by indirectly estimating the mean concentration of the tracer in the inflowing groundwater.
