Development and application of field methods for determination of the extent of acid mine drainage contamination and geochemical characteristics of stream sediment recovery
… sources of AMD as it flows through the city of Black Hawk, Colorado. I modified an existing field method to monitor benthic invertebrate populations in-situ, to examine the flux of metals on stream sediment in both deposition and recovery scenarios. Also using my developed methods, I was able to …
