Professional Projects


Central Plateau Cleanup Company : Recharge Source Determination of 100-HR-3 Groundwater using Multivariate Analysis.


Technical and Document Lead. Lead development and implementation of machine learning and unsupervised analytical methods for determining sources of groundwater recharge for the purposes of identifying inter-aquifer hydraulic connections and surface water/groundwater interactions. This effort combined multiple datasets from multiple sources and conditioned the data using appropriate transformations and scaling. Then hierarchical cluster analysis and principal component analysis were performed to identify groundwater recharge endmembers, endmember mixing, and hydrochemical reaction pathways. The purpose of this project is to identify areas where future characterization is needed (i.e., pumping test well location selection) and to estimate the impact of pump and treat operations on the groundwater hydrochemistry. Data wrangling and multivariate analysis were performed using R.


Central Plateau Cleanup Company : Waste Management Area A-AX Tank Farm Groundwater Contamination First Determination.


Technical and Document Lead. Lead development of a detailed groundwater chemical data evaluation for determination of impact to groundwater from the facility. This effort involved data compilation from a large database, validating the data and then evaluating it using hypothesis testing (t-tests) and ANOVA in R. Valid detections of dangerous waste constituents were statistically evaluated at upgradient and downgradient locations with respect to groundwater flow, in order to determine if leaks from the tank farm were responsible for impact to the aquifer beneath the site. A first determination report was written detailing the findings of the data evaluation and statistical comparison for presentation to regulators. Results showed that the site was not impacting groundwater and as a result, monitoring requirements were eased.


INTERA : Waste Management Area C Post Closure Performance Assessment.


Task Lead. Evaluated previously generated experimental residual tank waste contaminant solubility and release data to develop input parameters for numerical contaminant transport models. Oversaw project budget tracking and generation of a monthly budgeting report.


INTERA : Initial Groundwater Plume Development to Support Fate and Transport Modeling for Remedial Investigation/Feasibility Studies of the 200-BP-5 and 200-PO-1 Groundwater Operable Units.


Technical and Document Lead. Used existing groundwater and depth-discrete contaminant of potential concern (COPC) concentration data to created initial condition 3D contaminant plumes to be used in groundwater flow and transport numerical models. Plume creation involved data compilation, creation of two-dimensional plume extent raster grids, determination of aquifer units containing the plumes and plume depth boundaries, creation of a plume depth boundary surface, and assignment of plumes to a fate and transport model grid.


GSI Water Solutions : Hydrochemical Characterization of CRBG Groundwater and Groundwater Mixing Model Development for Grant, Adams, Lincoln, and Franklin Counties, Columbia Basin Groundwater Management Area, Othello, WA.


Task Lead. Created a hydrochemical mixing model using maximum likelihood estimation methods. This model differentiated recharge end members and quantified their respective contribution quantities to mixed groundwater in basalt aquifer production wells. This model was instrumental in identifying different hydrochemical facies in confined basalt aquifers and whether these aquifers receive recharge from a modern source. This work had major groundwater resources implications for groundwater users in the Columbia Basin.
