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.
