Environmental Chemistry Laboratory
Chemical analysis has long been an integral component of complete water and sediment quality assessments.
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
especially strong capabilities in sediment and tissue analysis. GLEC has completed numerous integrated
surveys of large and small water bodies involving the collection and chemical analysis of water and effluent
samples, biological tissues, and sediment samples for both organic and inorganic constituents. GLEC’s
chemistry lab is equipped to conduct low-level nutrient chemistry and a wide array of organic chemistry
analyses. Stringent Quality Assurance/Quality Control (QA/QC) procedures are routinely applied and Good
Laboratory Practices (GLP) are implemented when necessary. All laboratory practices follow written Standard
Operating Procedures.
