It would be interesting to learn exactly what was in the fracking fluids spilled near Canton, PA, when, as of April 23

Workers stopped the flow of liquid and natural gas from a well that spilled chemical-laced water for two days and were hoping to start on a permanent solution to control the well

What were the compounds in the fracking fluids, and what were their concentrations? I’d think the company would have to tell the Pennsylvania regulators.
