More leaking coal ash ponds

The St. Louis Post-Dispatch reports that for 19 years, a coal ash storage pond owned by the power company Ameren. The unlined pond in Labadie has never been linked to groundwater contamination, but a slow and steady leak from the site has been known of by Ameren and Missouri state regulators for nearly two decades. Similar ponds in Venice, Illinois are most likely to be capped (by state requirement), and a similar strategy may come to Labadie. Learn more here.;

Maccaferri Introduces MacDam for Ash and Fine Sediment Control in Burned Areas

Maccaferri, a leading provider of Civil Engineering and Environmental solutions for over 130 years, has developed the MacDam™ to control ash and fine sediment runoff on burned or barren slopes. Fire is an ever present force in forests and rangeland and is an important natural process in the renewal of ecosystems. However, as human populations expand, people and their homes, businesses and public infrastructure are not only threatened by the incidence of natural and man-induced wildfires, but ultimately areas affected by fire can succumb to a secondary disaster resulting from the erosion of barren soils.
