RESEARCH

This project was funded in 1996 by a SBIR award to Hedin Environmental.  Since the project was completed, Iron Oxide Recovery Inc. was formed and we have recovered and sold 3,000 tons of iron oxide. 

This ongoing project is developing a method for controlling phosphorous releases from animal manures using mine drainage solids.  The project has been conducted in conjunction with Trout Unlimited.

This project was funded in 2005. By PADEP BAMR.  It resulted in the devlopment of the Drainable Limestone Bed technology which is being implemented at sites across PA.
