Region 9 Analytical Services
Laboratory testing of soil, water and/or air samples for hazardous chemicals may be conducted through the EPA Contract Laboratory Program and EPA Regional Laboratory Program. Laboratory analysis time is scheduled through the Regional Sample Control Coordinator (RSCC) in the EPA Region 9 Laboratory before a sampling event takes place.
Contract Laboratory Program
The EPA Contract Laboratory Program (CLP) is a national network of EPA personnel, commercial laboratories, and support contractors whose fundamental mission is to provide data of known and documented quality for EPA’s Superfund program. CLP analytical services are based on proven and tested EPA analytical methods, and are used by CLP laboratories for the isolation, detection, and measurement of the CLP's target compounds and analytes. The CLP currently offers the following routine analytical services:

Approved analytical methods must be used when analyzing water samples to meet federal monitoring requirements or to demonstrate compliance with drinking water regulations. EPA reviews and approves methods that can be used. Laboratories that analyze these compliance samples must be certified by EPA or the State.
Clean Water Act Analytical Methods
EPA publishes laboratory analytical methods that are used by industries and municipalities to analyze the chemical, physical and biological components of wastewater and other environmental samples that are required by regulations under the authority of the Clean Water Act (CWA). Most of these methods are published as regulations in the Code of Federal Regulations (CFR) at Title 40 Part 136.
