In fact, I haven't posted in a number of months. As a result, we are expanding the blogs to include multiple authors in the Groundwater Science Section at the Illinois State Water Survey, Prairie Research Institute at the University of Illinois. The scope of the blog posts will be broadened to include many topics on groundwater, not just water quality, still with an emphasis on Illinois, although not limited to our state. We hope you enjoy the new look, and we look forward to your feedback.primary for post 443609Fish Adapting to PollutionDec 22, 2016 4:15 pmA paper published in Science reports that genetic adaptions in the Atlantic killifish (Fundulus heteroclitus) allow it to survive what, in unpolluted environments, would be lethal levels of bioaccumulative dioxin-like contaminants.primary for post 443602Animas River Spill Follow-UpDec 22, 2016 3:45 pmThe first peer-reviewed paper (as far as I can tell) related to the Animas River, Colorado, was recently published.
