Analysis of pet coke samples submitted by KCBX

EPA required KCBX to submit samples of the petroleum coke stored on each of their sites for EPA to analyze in our labs. EPA is publishing the resulting data on this website.

What is EPA doing with the results?

All of the pollutants that are being analyzed in samples of pet coke from KCBX are typically found at low levels in common topsoil. EPA expects to find some amount of metals, polycyclic aromatic hydrocarbons and naturally-occurring radionuclides in the pet coke samples.

The reason for sampling is to understand exactly how much of these pollutants are found in the pet coke stored at KCBX. These results can be compared to coal and pet coke sampled in Detroit or other locations.
