ProUCL version 5.1.002 (5.1) is the latest update of the ProUCL statistical software package for analysis of environmental data sets with and without nondetect (ND) observations. The ProUCL software is available at This final installment of the three part ProUCL e-learning seminar will focus mainly on background dataset analysis and associated background threshold value (BTV) comparisons within the ProUCL software. General discussion points will include

  • Background dataset analysis
  • Appropriate sample size selection
  • UTLs and background threshold values
  • Comparison of BTVs to site data

A ProUCL provided background environmental dataset (XLS) will be used as an example throughout the presentation. This dataset is provided here and it is encouraged for attendees to follow along on their local machine.

She is also the Region 4 Superfund and Technology Liaison for the Office of Research and Development (ORD). Felicia is the ORD resource for characterization technologies/performance support to the EPA program and regional offices and research/engineering/liaison technical support to EPA Region 4 located in Atlanta, Georgia. She provides expertise to the Region's waste programs on investigative, subsurface/groundwater, and engineering technical support and innovative technologies, including pesticides, brownfields, wood treaters, metals, and phytoremediation along with national contacts within ORD for those and other fields/wastes.

She joined the EPA in 1985 as a Site Assessment Manager for the Superfund Program. She later worked as a Remedial Project Manager for Hazardous Waste Site cleanups and has worked for over twenty years in the Office of Research and Development.

Felicia holds a BS degree in Chemical Engineering from the University of Tennessee in Knoxville.

Travis Linscome-Hatfield, Neptune and Company, Inc. ( or 720-746-1803)
As a graduate from the University of Colorado at Boulder, with a dual B.A. in Mathematics and Economics, and a graduate of the University of California at Santa Cruz with an M.S. in Statistics, Mr. Linscome-Hatfield has strong experience working with both Bayesian and Frequentist statistical methods. This experience is tied to his deep interests in both transportation and natural resource economics, which have provided ample opportunities for the creation of statistical models. These statistical analysis and modeling interests are enhanced by Mr. Linscome-Hatfield's expert skills with multiple statistical and general data analysis programs, such as Excel, SQL, JAGS, ProUCL, and most strongly with R.
