Superfund Analytical Services / Contract Laboratory Program (CLP)


Who Makes it Happen?

The CLP is directed by the EPA Headquarters' Analytical Services Branch (ASB) in the Office of Superfund Remediation and Technology Innovation (OSRTI) located in Washington, DC. A supportive infrastructure has been established in order to successfully manage the CLP. The following organizations play a key role in the CLP.

EPA Analytical Services Branch (ASB)

EPA’s ASB is responsible for the overall management of the CLP program. ASB activities include:

  • Development, administration, and monitoring of CLP analytical and support services contracts;
  • Direction of Quality Assurance (QA) for CLP and non-CLP analytical data;
  • Development and implementation of electronic sample tracking and data assessment tools, and
  • Promotion of field characterization technologies.

ASB communicates with customers on a regular basis in order to keep all parties apprised of program activities, as well as to receive feedback for continued improvement of program operations.

EPA Regional Personnel

The United States is divided geographically into ten EPA Regions. These Regions play an important role in CLP activities as the primary users of the CLP and as a key part of analytical program management. Two important participants within the Regional personnel structure are the CLP Contracting Officer Representative (COR) and the Regional Sample Control Coordinator (RSCC). The CLP CLP COR monitors contract laboratories within the Region, responds to and identifies problems in laboratory operations, and participates in on-site laboratory programs. The RSCC serves as the central point of contact for sample scheduling questions and problems. The RSCC also coordinates the selection of contract vehicles for Regional sample activities to correspond with the monthly projected demand for analytical services.

Sample Management Office (SMO) Contractor

SMO provides ASB with administrative, operational, and information support such as scheduling sample analysis with laboratories, tracking invoices, and assisting with contract compliance tools. SMO’s primary objective is to maintain the CLP laboratory and data resources so its use may be optimized by CLP customers.

CLP Laboratories

The CLP analytical contractors come from the nationwide community of chemical analytical laboratory facilities. In order to become a CLP laboratory, a laboratory must first be awarded a contract. Fixed price contracts are awarded through the Government’s bid process after bidders pass performance tests. Bidders must successfully analyze Performance Evaluation (PE) samples and pass a pre-award laboratory audit, then awards are made to the lowest bidders. In addition, laboratories must meet stringent requirements and standards for equipment, personnel, laboratory practices, and analytical and Quality Control (QC) operations. EPA and CLP support contractors monitor CLP laboratory performance after contracts are awarded.

The CLP laboratory plays an important role within the CLP. The CLP laboratory is responsible for:

  • Logging and maintaining all CLP samples received at their facilities;
  • Documenting all processes and procedures associated with CLP samples;
  • Analyzing samples and compiling data according to CLP requirements; and
  • Submitting data deliverables in the specified time frame.

All data deliverables are reviewed to ensure that the laboratories are meeting the administrative and technical requirements of their contracts.

A list of current CLP laboratories is available on the Active CLP Laboratories page.
