Additional InfoPrior to 1985, four different state laboratories performed analyses of samples, and there are known discrepancies among the labs' results for certain organics. We are not able to say if there were also discrepancies in mercury results for this period, but the Illinois EPA does not routinely use these Hg data in analyses. Since 1985, all samples have been analyzed by the Illinois EPA lab or a a contract lab under its supervision. The IL EPA does maintain a tissue bank of all samples from the preceding 15 years.
