Thomas E Imbrigiotta

Tom Imbrigiotta has worked for the USGS since 1977 in Indiana and New Jersey on groundwater contamination and sampling devices. He has served the USGS New Jersey Water Science Center as Water Quality Specialist, Supervisory Hydrologist, and Research Hydrologist, and became a Scientist Emeritus Hydrologist in 2019.

Research Interests

  • Quantifying natural attenuation and enhanced bioremediation processes in contaminant plumes
  • Chemical diffusion from fractured rock into boreholes
  • Rock core sampling for volatile organic compound (VOC) contaminants in fractured rock aquifers
  • Regenerated-cellulose dialysis membrane (RCDM) passive diffusion samplers for VOCs, inorganics, perchlorate, and explosive compounds in wells
  • Sampling methods for organics in groundwater

Professional Experience

  • 2005-2019 Research hydrologist and project chief of the NAWC Navy project at the former Naval Air Warfare Center in West Trenton, NJ. Conducted research for the Toxics Substances Hydrology Program and a Strategic Environmental Research and Development (SERDP) project at the NAWC fractured rock research site. 

  • Helped develop and test a downhole packer tool and uphole closed-loop sampling device to measure diffusion rates from the rock matrix and biodegradation rates in the borehole.

  • 2014-2016 Water Quality Specialist, NJWSC

  • 2009-2014 Supervisory Hydrologist, Hydrologic Research Program section of the NJWSC

  • 2003-2008 Project chief, Environmental Security Technology Certification (ESTCP) study developing a RCDM diffusion sampler for groundwater in wells

  • 1997-2005 Senior hydrologist studying natural attenuation mechanisms in New Jersey aquifers contaminated with VOCs

  • 1988-1997 Project chief and coordinator of an interdisciplinary research study of the fate and transport of chlorinated solvents in an unconfined sand-and-gravel aquifer at Picatinny Arsenal, NJ, the USGS Toxic Substances Hydrology Program's national research site for chlorinated solvent contamination research in unconsolidated aquifers

  • 1984-1988 Project chief for evaluation of methods for sampling organics in groundwater

  • 1977-1984 Project chief for investigations of groundwater quality in Indiana
