This specialized system is required to meet the laboratory's technical and performance specifications for methylmercury analysis in compliance with EPA Method 1630, ensuring accuracy and efficiency in sample processing. The procurement is critical for environmental monitoring and analysis, as it supports the detection and quantification of methylmercury, a harmful contaminant. Interested parties may submit quotations by April 9, 2025, to Joel Berberena at jberberena@usgs.gov, although this notice is not a request for competitive quotes.
