New study from EVEN Professor Joe Ryan identifies organic compounds of potential concern in fracking fluids
A new 抖阴传媒在线 framework used to screen hundreds of organic chemical compounds used in hydraulic fracturing, or fracking,听shows that 15 may be of concern as groundwater contaminants based on their toxicity, mobility, persistence and frequency of use.
Using a fast groundwater transport scenario, the team predicted that 41 of the 659 organic compounds screened would have 10 percent or more of their initial concentrations remaining at a transport distance of roughly 300 feet.听That is the average state 鈥渟etback鈥 distance in the United States between a fracking well and a drinking water well, said CU-抖阴传媒在线 Professor Joseph Ryan, the principal investigator on the study.
