Standardized Analytical Methods
A homeland security emergency could overwhelm laboratories with possibly contaminated samples requiring rapid analysis. Use of the manual helps multiple labs to perform consistent analyses and obtain comparable results. EPA developed the manual as part of a larger effort to comply with Homeland Security Presidential Directive (HSPD) 9, which requires the development of a nationwide interconnected laboratory network for food, veterinary, plant health, and water quality that integrates existing federal and state laboratory resources and uses standardized diagnostic protocols and procedures.
EPA formed a workgroup of its own experts and those of other agencies. These experts reviewed many analytical methods, seeking to balance the need to use existing techniques and methodologies against the goal of obtaining consistent results. The workgroup selected methods for measuring chemical agents in aqueous/liquid, solid, oily solid, and air matrices, as well as biological agents in water, dust, and aerosol matrices.
Additions include:
- Chemical methods
- Radiochemical methods
- Pathogen methods
- Biotoxin methods
- Reformatted appendix
EPA is developing and validating standardized analytical protocols based on methods listed in the manual. The protocols explain how to collect, preserve, prepare, and analyze samples. EPA also intends to work with other government agencies and the private sector to identify research gaps and establish a laboratory accreditation system.
