Dr. Brueck is an environmental engineer-in-training in Ģ��tv's Environmental & Earth Sciences practice. He specializes in environmental chemistry and microbiology with particular emphasis in agricultural waste management and environmental chemical fate and transport. He also has expertise in the areas of analytical chemistry, nontargeted analysis, cheminformatics, and data science for chemical identification. Dr. Brueck helps clients tackle problems related to site investigation and remediation, chemical forensics, carbon offset technology, and data retrieval and management.

Dr. Brueck's research has focused on the fate of anthropogenic organic chemicals in a variety of matrices including wastewater, animal manure, biosolids, and vegetables using modern analytical chemistry and data analysis techniques. He has experience modeling chemical degradation kinetics, measuring contaminant partitioning coefficients, and identifying transformation products and metabolites from the biodegradation of various pesticides, antibiotics, and animal feed additives during anaerobic digestion. Dr. Brueck has developed computational methods to process large chemical datasets to identify and predict molecular relationships.

Dr. Brueck is skilled in data visualizations, multivariate statistical analyses, and task automation using R and Python programming languages. He has developed image processing methods for particle tracking in 3-dimensions from datasets produced by x-ray microtomography. Chris has analytical expertise in high-performance liquid chromatography (HPLC) coupled with high-resolution mass spectrometry (Orbitrap and QTOF), gas chromatography (GC) with either thermal conductivity detectors (TCD) or flame ionization detectors (FID).

Sediment
Performed positive matrix factorization (PMF) with the EPA tool PMF 5.0 and identified multiple contaminant sources during a chemical forensics investigation (with polycyclic aromatic hydrocarbons [PAHs], metals, and dioxins/furans) in a river with contaminated sediment.
Filtered data for GIS spatial analysis and assessed different spatial interpolation methods for concentration contour mapping in surface and subsurface river sediments.
Created an R-based mapping tool to identify and download relevant total suspended solids (TSS) data from U.S. Geological Survey (USGS) stations. Evaluated temporal trends in support of a river sediment transport analysis.
Groundwater
Performed data mining of California Water Board's GeoTracker for a major industrial oil company to assess the magnitude and spatial extent of groundwater contamination at California remediation sites.
Wrote R scripts to conduct multi-year statistical trend analysis (Mann-Kendall) to evaluate the attenuation of groundwater contaminants including benzene, methyl tert-butyl ether (MTBE), total petroleum hydrocarbons (TPH), tetrachloroethene (PCE), and others.
Identified groundwater contaminants that exceeded drinking water maximum concentration limits (MCLs) and created a portfolio highlighting risk drivers at sites of interest in California.
Surface Water
Evaluated the temporal relationships between various water quality parameters within a hypereutrophic lake from a dataset spanning multiple decades.
Carbon Offsets
Designed a testing program to assist in the evaluation of a methane emission control product. Evaluated available data and collaborated on a scientific manuscript demonstrating efficacy of the product. Data are intended to support a carbon offset credit application.
Data Analytics and Management
Developed tools and automated scripts to access and summarize publicly available data from the following sources:
· USGS National Water Information System (NWIS) mapper
· U.S. Environmental Protection Agency (EPA) Water Quality Portal (formerly STORET)
· EPA CompTox Dashboard
· PubChem
· California's Water Boards GeoTracker
