Work on Water and Sediment Quality in the San Juan River (NM, UT)

During a recent, high profile, chemical waste spill I analyzed daily surface water and sediment samples in the San Juan River for total metals.  I coordinated my work with multiple State and Tribal agencies and EPA headquarters.  I established historical background concentrations which served as benchmarks throughout the event.  Sediment contamination mapping was aided using hydrometrological information for the river system.
