NOAA Performance Based Methods

We employ methods utilized by NOAA's NS&T (National Status and Trends) Mussel Watch Program and the USEPA's EMAP (Environmental Monitoring and Assessment) Program. These are also the methods used by the National Institute for Standards and Testing (NIST) Annual Intercalibration Exercises and the U.S. Fish & Wildlife Service (USFWS) ongoing monitoring program. As such, this set of analytically rigorous methods is often called the NS&T-EMAP-NIST-USFWS performance-based method set for baseline monitoring.

Our staff is skilled in trace contaminant analyses and interpretation of environmental data as evidenced by the team's extensive experience in several trace contaminant-monitoring programs for the U.S. Fish & Wildlife Service (USFWS), NOAA (NS&T Program), USEPA, the Office of Naval Research (ONR), and the Minerals Management Service (MMS). We have established a reputation of excellent quality, timely performance and data submission as well as competitive pricing. Over the last six-years, we have developed and demonstrated considerable project experience relative to our ability to provide high quality trace organic analysis particularly related to tissue residues, using the methods presented here.
