In April, our paper, Chemical Assessment State of the Science: Evaluation of 32 Decision-Support Tools Used to Screen and Prioritize Chemicals, was published in SETAC's IEAM journal. My co-author, Julie Panko, sat down for a chat with Jenny Shaw to discuss our analysis. Please follow this link to listen to the podcast or read the transcript.

If you, too, are lucky to live in beautiful western Pennsylvania, you have probably heard about hydraulic fracturing or “fracking’”as it is commonly called. But if not, fracking is a process by which high-pressure fluids are injected into a well to propagate fractures in the rock formation, enabling extraction of natural gas and oil from previously untappable sources such as deep shale formations. While most of the fracking fluid is water and sand, a variety of chemicals are added, including biocides, breakers, surfactants, scale inhibitors, clay stabilizers and friction reducers. Concern from the public and the regulatory community has risen to a feverish pitch with respect to the potential contamination of groundwater and surface water by the fracking fluid chemicals. Because there is no way to extract the gas without some sort of fracking fluid, it seems wise to ensure that the fluid being injected poses the least amount of risk as possible. Using composition information available through the public database FracFocus, in combination with the chemical footprinting method we described last month, Cardno ChemRisk has evaluated several different fracking fluids.Continue reading
This week, Cardno ChemRisk scientists are attending the 33rd Annual Meeting of the Society of Environmental Toxicology and Chemistry in Long Beach, California. They will be giving poster presentations on topics including hydraulic fracturing and sustainability initiatives of the global tire industry. Look for more information on this meeting here; and if you are in attendance, be sure to stop by our posters on Tuesday and Wednesday.
