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. An estimated 3 million gallons of toxic acid mine drainage water was released into a small tributary of the Animas River due to the failure of a dam containing the waste.primary for post 430729Large Study of Bacterial Water Quality in Sub-Saharan AfricaNov 17, 2016 10:45 amA just released study did a meta-analysis of almost 43,000 water samples from 7 countries in sub-Saharan Africa to assess the amount of bacterial contamination and how it varied with respect to source type.primary for post 425458Micro- and NanoparticlesNov 3, 2016 9:00 amThere are both natural and engineered micro- and nanomaterials in our world. Ocean spray, smoke, and milk all contain natural nanomaterials. In recent years, engineered materials have been designed and produced with many useful applications.primary for post 423237Thermal PollutionOct 28, 2016 10:15 amIn surface water, temperature is an important water quality parameter affecting aquatic organisms, and a recently published paper has looked at the magnitude of thermal pollution in many river basins throughout the world.primary for post 386945Triclosan and MicrobiomesJul 22, 2016 4:45 pmTriclosan is a very common antibacterial compound, used in antibacterial soaps and toothpaste, and it is found in humans (detected in about 75% of urine samples in the U.S. in 2008) and in the aquatic environment.
