​Expert Services in Surface-Water and Groundwater Contamination

Surface-Water and Groundwater Contamination Services

 ​Since the mid 1980s, Dr. Connors has investigated and provided scientific assistance with the cleanup of environmental contamination. His consulting practice in this area has involved projects and legal cases focused on contaminant sources, fate, and transport of a wide variety of chemicals, contaminated media (soil, sediment, vadose zone, confined and unconfined aquifers, stormwater, surface waters, and biota), and contaminant phases (NAPLs, dissolved, vapors, etc.).  He has served as an expert witness and/or consultant on many projects and legal cases involving PFAS, landfills, pipelines, above- and underground storage tanks (USTs), rail yards, construction sites, refineries, wetlands, surface spills and releases, chemical/manufacturing plants, oil/gas fields, military bases, commercial sites, casinos, agriculture and aquaculture facilities, and many other sites.  His work has involved well installation and sampling, computer modeling, statistical analysis, plume-stability evaluations, data review and validation, geophysical surveys, aerial photos and drone imagery, contamination forensics, and risk-based decision-making and remediation.
