:: Whole Effluent Toxicity
ERA Whole Effluent Toxicity (WET) QC standards allow you to assess the consistency and quality of your routine aquatic toxicology analyses. All toxicants are supplied as ready-to-dilute concentrates; simply dilute and test. The standards are provided with QC Performance Acceptance Limits (PALs™), which are based on the data from ERA’s historical proficiency testing studies. The WET QC standards are also designed to be Perfect Partners™ to our WET DMR-QA PT samples. Analyze them first and work out any problems before participating in your DMR-QA study – they will help you and your permittees avoid the hassle of any unnecessary Corrective Actions.
