Craig Hutchings is a chemist with more than 25 years of experience in environmental investigations, environmental analytical chemistry, and QA/QC data review and validation. He is responsible for the preparation of sampling and analysis plans (SAPs) and quality assurance project plans (QAPPs), data interpretation, and development of quality assurance programs for sites within various state and federal regulatory programs. Mr. Hutchings has coordinated communication between laboratories and data users on several projects involving performance-based methods for non-standard analytes and methods to ensure that methodologies, data quality, and deliverables meet project needs. Mr. Hutchings has validated both the newly developed methodologies used for these projects and the data generated. He has authored numerous SAPs and QAPPs that comply with federal or state regulatory programs and take into account unique data quality objective requirements of specific projects. Mr. Hutchings has performed and supervised gas chromatography, high performance liquid chromatography, and gas chromatography/mass spectrometry analyses for contaminants in soil, sediment, water, and tissues using EPA and various state methods. He is experienced in the evaluation and review of analytical data including outputs from inductively coupled plasma instruments and chromatograms for Aroclors, pesticides, and other compounds and has reviewed chemistry data from numerous projects involving a wide variety of analyses in air, water, soils, sediments, and tissues.
