Audit Process

The Office of Quality Assurance (OQA) audits environmental laboratories that have applied for accreditation in either New Jersey's Environmental Laboratory Certification Program (ELCP) or New Jersey's National Environmental Laboratory Accreditation Program (NELAP). Also, OQA performs audits on laboratories that have applied for new methods. Once an initial audit has been performed on a laboratory, the OQA will inspect the facility on a biennial schedule to ensure that it complies with current regulations. These regulations include N.J.A.C. 7:18, et al. for ELCP laboratories and the most current NELAC Standards for laboratories that are NELAP Accredited.

The audit process begins when a laboratory submits an application in which they apply for new certification for a particular method(s). At this stage, the laboratory is in "Applied" Status for that method and can not perform regulatory work until it has met all of the certification requirements. The certification requirements include submitting a Standard Operation Procedure (SOP), a Method Detection Limit (MDL), Precision and Accuracy Study (P & A), acceptable Proficiency Test (PT) results, and have participated in a satisfactory audit. In addition, if a laboratory is participating in the NELAP program, a Quality Manual that satisfies all of the requirements listed in the NELAC standards must be submitted to the OQA.

Once a SOP, MDL Study, P & A Study, and acceptable PT results are submitted to the OQA, an auditor will contact the laboratory to schedule the audit. The audit usually consists of two parts, the in-house audit and the on-site audit. The in-house audit involves an OQA review of all the information submitted from the laboratory (i.e.-SOPs, MDLs, etc.). The on-site audit involves one or more auditors visiting the facility to ensure that the laboratory has the appropriate personnel, equipment and capabilities to perform the method requested. Any deficiencies noted at the time of the audit are presented to the laboratory in a formal letter within 30 calendar days following the audit. The laboratory has 30 calendar days to respond to the deficiencies. If the laboratory response is deemed acceptable, then the laboratory is granted accreditation.

CLP Accreditation

Important Notice: FY2015 Application to include EPA’s CLP newest SOWs (ISM02.1 and SOM02.1)

OQA will offer accreditation for Multi-Media, Multi-Concentration Inorganics Analysis, ISM02.1 and Multi-Media, Multi-Concentration Organics Analysis, SOM02.1 to laboratories beginning July 1, 2014.  Laboratories must apply for the newest Statements of Work (SOW)s through the OQA’s Part III application process to be considered for accreditation.

General Information:
Multi-Media, Multi-Concentration Inorganics Analysis, ISM02.1
ISM02.1 defines the analytical methods for the isolation, detection, and quantitative measurement of 23 metals and cyanide in aqueous/water and soil/sediment samples, and total metals analysis in wipes. The SOW also includes Toxicity Characteristic Leaching Procedure (TCLP) and Synthetic Precipitation Leaching Procedure (SPLP) leachate extraction procedures. Analyses are performed using Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES), Inductively Coupled Plasma-Mass Spectrometry (ICP-MS), Cold Vapor Atomic Absorption (CVAA), and colorimetric techniques.
Multi-Media, Multi-Concentration Organics Analysis, SOM02.1
SOM02.1 defines methods for the isolation, detection, and quantitative measurement of trace volatile, low/medium volatile, semivolatile, pesticide, and Aroclor target compounds in water and soil/sediment environmental samples.

PLEASE NOTE!!

SOM02.1 is a new statement of work with significant technical and reporting changes. EPA recommends a thorough review of the document.

For further information, specific details, and recent amendments regarding ISM02.1 and/or SOM02.1 please refer to the following links:
