Barcelona has received a number of awards throughout the United States. Barden is senior hydrogeologist with Hydro Geo Chem Inc.
Previous to his position with the Association, he served as chief of the Office of Groundwater at the U. Alley served as the 2012 David Keith Todd Distinguished Lecturer for the Groundwater Resources Association of California and was named a Fellow of the Geological Society of America in 2009. Alley earned a bachelor's degree in geological engineering from the Colorado School of Mines, a master's degree in hydrogeology from Stanford University, and a doctorate in geography and environmental engineering from the Johns Hopkins University. Anderson has helped pioneer programmatic surveillance of emerging contaminants and issues, as well as provide technical expertise to the U. AF Environmental Restoration Program in the areas of soil science, environmental toxicology, and quantitative data analyses. His current research focuses on groundwater contamination caused by agricultural and industrial activities. Her current research focuses on community-scale geothermal heat pump systems. He's an associate editor for Groundwater Monitoring & Remediation®, an NGWA publication, and has also authored or coauthored numerous papers, book chapters, and reports.
Activity of a radioactive sample is defined as the number of decays per unit second and is measured in Bq: The activity of a sample depends on the decay constant, λ, and the number of isotopes at a given time: At any given time C) of .
Determine the age of a sample based on the following lab measurements: Total mass of carbon in the sample: 500 mg Activity of sample: 174 decays per hour.
With more than 25 years of experience in consulting hydrogeology, he has expertise in groundwater source development, aquifer storage and recovery, water rights consulting, groundwater modeling, regional hydrogeologic definition, and contaminant hydrogeology. Peter Bennett, PG, CHG, lead hydrogeologist and vice president of Haley & Aldrich Inc., has more than 18 years of experience with innovative site characterization and remediation projects.
