Last year, drought conditions in Europe really hit the headlines, with a series of intense heatwaves leading the continent to experience its hottest summer on record which, in turn, resulted in withered crops and premature deaths. Research published last month (April) from the Copernicus Climate Change Service, reported on by the Guardian, found that the climate crisis resulted in frightening ...
Collaborators who helped answer the questions "why" and "how" included Rodney Presley and Professor a James Lynch from Chemistry and Bioengineering who helped identify the mechanisms of protein transformation at the molecular level. Colleagues in geoscience at Princeton University assisted in measuring water filtration. ...

Water resources underpin every aspect of modern society and without them everything would eventually grind to a halt… including whisky distilling! In fact, the industry is very water intensive, with water one of the three essentials necessary to facilitate the process, alongside malted barley and yeast. The word ‘whisky’ actually comes from the Gaelic uisge beatha, which means ...
Date Conducted: June 2013 to January 2014 Client: EcoInnovators Oversite Agency: Indiana DEM Project Description: Vapor intrusion assessment of an existing commercial building and surrounding residential neighborhood. Contaminant of concern: PCE. Hartman wrote investigation work scope, oversaw soil gas sampling program to define PCE vadose zone contamination, conducted on-site indoor air ...
Date Conducted: Feb 2017 – ongoing Client: OTIE Oversite Agency: EPA Region 9 Project Description: Continuous monitoring of indoor and ambient air for vinyl chloride, TCE and PCE at 14 locations across and bordering a site undergoing thermal heating remediation. This is the first time that vinyl chloride in air has been measured in real time. Data were collected prior to heating and during ...
Date Conducted: June 2016 to January 2017 Client: Hull & Associates Oversite Agency: EPA Region 1, NH-DEH Project Description: Continuous monitoring of indoor and ambient air for TCE and PCE at 15 locations inside an active manufacturing facility at a site undergoing thermal heating remediation. Data were collected prior to heating and during heating to ensure the vapor recovery system was ...
Date Conducted: Feb 2017 – April 2017 Client: Tetratech/CDM Smith Oversite Agency: none Project Description: Continuous monitoring of room air and sump air in a basement for TCE and PCE at 15 locations with goal to understand the cause and effect of TCE concentrations in a large basement under an industrial building. The real-time data enabled immediate recognition of indoor TCE ...
Date Conducted: August 2011 to February 2012; December 2012 to March 2013 Client: Dr. Brian Schumacher, EPA-ORD, Las Vegas Oversite Agency: EPA-ORD Project Description: Research program by EPA studying temporal variation of soil gas and indoor concentrations. Hartman proving real-time, continuous (24 hour) monitoring of chloroform, TCE, and PCE by method TO-14 for a period of 7 ...

Interpretation of groundwater chemistry using piper and chadha´s diagrams: A comparative study from Perambalur Taluk. Elixir Geoscience, 54, 12208-12211. Montoya, S. (2018). What is a Piper diagram for water chemistry analysis and how to create one? ...
The part of my job that I like most is traveling to new places and working with new customers. I have had the pleasure to work with many customers who were bringing NMR geophysical technology into their region and/or market application for the first time. Being in the field with a new customer when they see a magnetic resonance signal from groundwater for the first time – on their own ...
Design Approach: A second cleanup effort was then designed, which included a combined remedy approach using in situ chemical reduction (ISCR) and enhanced bioremediation. Arnie Sugar of HWA GeoSciences Inc. led the restoration effort. HWA contracted Leo Lehmicke, Ph.D., to help design the cleanup, which included ‘flipping’ the aquifer chemistry to a reducing ...
But deep below the ocean, there is a source of clean carbon energy waiting to be harvested, which will go a long way to reducing our dependence on oil, gas and coal – seaweed. A recent study in Nature Geoscience estimated that seaweed floating down to the depths of the ocean naturally sequesters 173 million tons of carbon a year, about as much as New York City emits, and ...
Australia's main mining deposits Source: Geoscience Australia, 2016. Some mining companies have invested in PV and wind solutions to reduce carbon emissions. ...
According to Bridget Scanlon, senior research scientist at UT Austin’s Bureau of Economic Geology at the Jackson School of Geosciences, “This study is the first step, but it looks like the water is worth going ...
