ENVIRONMENTAL WASTE WATER CHEMISTRY

The test materials supplied are standard concentrates or standard solutions. All Groups, except 2 & 4 require dilution with your laboratory's reagent water before analysis. Full instructions regarding this dilution step will be provided. When diluted the test materials will contain levels of contaminants usually, found in waste water / effluent samples. The volume of concentrate supplied, required dilution, and description of each analyte group is shown on pages 22-24 of the Water and Environmental Proficiency Testing brochure.
