Emerging Contaminants New methods have recently been added to NEMI for the analysis of water for a class of chemicals often referred to as "emerging contaminants". These include methods from USGS (O-1433-01; O-2060-01; and O-2080-08) and EPA (1694 and 1698) for analysis of pharmaceuticals, personal care products, and wastewater compounds. |
