Industrial / Analytical LabsU.S. Environmental Protection Agency (EPA) Clean Water Act Analytical Method
EPA publishes laboratory analytical methods used by industries and municipalities to analyze the chemical, physical, and biological components of wastewater and other environmental samples required by regulations under the authority of the Clean Water Act (CWA). This site offers information on alternate test procedures, method flexibility, and other special topics.
EPA Clean Water Act Analytical Methods Alternate Test Procedures
EPA's Office of Science and Technology manages the program for CWA methods used by industries and municipalities to analyze the chemical, physical, and biological components of wastewater and other environmental samples as required by regulations. Analytical methods published in the Code of Federal Regulations (CFR) at Title 40 Part 136 may have alternate test procedures and/or method flexibility. This webpage provides guidance to allow labs to evaluate methods that could be adapted to micro-chemistry scale that reduce generated waste.
EPA Environmental Management Guide for Small Laboratories
This document assists those responsible for administering or improving environmental management programs at small labs. The document outlines management and federal regulatory issues for improving lab environmental performance, but does not prescribe in detail all required factors and considerations.
Greener Education Materials for Chemists (GEMs)
GEMs is an interactive tool for the organization and dissemination of core green chemistry materials with a focus on educational curriculums. This site may help identify alternative reagents or instrumentation that do not introduce or use hazardous substances in a method. Even though this is directed toward academia, commercial analytical labs evaluating modifications to standard methods may also find it useful.
King County Laboratory Waste Management Guide
This report was prepared by the Local Hazardous Waste Management Program in King County, Washington. The program seeks to reduce hazardous waste from households and small quantity generator businesses in King County by providing information and technical assistance to protect human health and the environment.
National Environment Methods Index (NEMI)
NEMI is a partnership of water-quality experts from federal agencies, states, municipalities, industry, and private organizations. The NEMI database includes a “greenness” profile for many common water quality regulatory standard methods. Analytical labs may adopt alternative standard methods that could reduce hazardous substances used or hazardous wastes generated.
Department of Ecology Accreditation of Environmental Laboratories
Ecology’s Laboratory Accreditation Unit oversees all accredited labs in Washington. They are familiar with all labs that have been accredited for modified standard methods and may help identify available alternative methods. Their publication titled Procedure Manual for the Environmental Laboratory Accreditation Program, includes guidance on the proficiency testing required before a lab can apply for accreditation for a modified method.
Department of Ecology: Accredited Laboratory Search
Some analytical laboratories in Washington have modified certain regulatory analytical methods and have earned accreditation for the modified method. Analytical labs may consider connecting with similar labs to inquire about modified analytical methods that use less hazardous substance or generate less hazardous waste.
