At GLEC we have the experienced staff, equipment, and resources necessary to conduct environmental chemistry evaluations, either in support of other programs or as stand-alone projects. GLEC has completed hundreds of integrated surveys of large and small water bodies involving the collection and chemical analysis of water, effluent, sediment, and biological tissue samples for inorganic constituents. GLEC’s stringent Quality Assurance/Quality Control (QA/QC) pro cedures comply with the National Environmental Laboratory Accreditation Program (NELAP). All laboratory practices follow written Standard Great Lakes Environmental Center Operating Procedures.
