NELAC and NELAP Decoded: Maximize Compliance with Environmental Laboratory Software

Environmental Laboratory Software for NELAP Accreditation

Environmental testing laboratories play a critical role in safeguarding our environment and ensuring that it is safe for all forms of life. They analyze samples from water, soil, air, and other sources to detect the presence and levels of pollutants and hence provide critical information for policymakers. To maintain the quality and reliability of their results, environmental labs  adhere to standards set by regulatory agencies. Among these, NELAC (National Environmental Laboratory Accreditation Conference) and NELAP (National Environmental Laboratory Accreditation Program) stand out. In this blog, we aim to demystify NELAC and NELAP and the important role they play in environmental testing.

What is NELAC?

NELAC is a nonprofit organization that was established in the United States to develop standards and accreditation programs for environmental laboratories. NELAC is not a specific acronym for an organization or program. Instead, the acronym represents a conference that was formed to develop and promote standards for accrediting environmental testing laboratories in the United States. 

NELAC’s primary objective is to establish uniform standards and practices for environmental laboratory accreditation to ensure that data produced by these laboratories is accurate, reliable, and consistent. Although NELAC itself does not directly give accreditation to laboratories, it provides guidance and standards that are implemented by individual states and accrediting bodies through programs like NELAP. These accredited laboratories play a crucial role in environmental monitoring to ensure compliance with regulations and to safeguard public health and the environment.

What is NELAP?

NELAP is a program managed and operated by individual states or agencies whose purpose is to ensure that environmental laboratories meet established quality and competency standards when conducting testing for environmental samples. NELAP provides a framework for accrediting laboratories that analyze various environmental media, including water, soil, air, and other substances.

NELAP accreditation is typically managed and operated by individual states or environmental agencies, with oversight from the NELAC. Laboratories seeking NELAP accreditation must adhere to rigorous standards and undergo a comprehensive evaluation process. This process includes assessments of the laboratory’s procedures, equipment, staff qualifications, data quality, and more.

The Significance of NELAC and NELAP

NELAP accreditation is not mandatory for all environmental laboratories in the United States. Whether or not a laboratory is required to obtain NELAP accreditation depends on various factors, including state regulations, federal regulations, and the specific type of testing and analysis the laboratory conducts. That said, labs that are accredited by this body enjoy the following benefits:

Consistency and Quality Assurance

NELAC and NELAP provide a framework for consistent and high-quality environmental testing. They establish standardized procedures and requirements that laboratories must follow. This consistency ensures that data produced by different labs are comparable and reliable.

Regulatory Compliance

A broad range of environmental regulations require testing to be conducted by accredited laboratories. NELAP accreditation helps labs meet these regulatory requirements, ensuring that their results are legally defensible.

Public Confidence

Accreditation under NELAP demonstrates a laboratory’s commitment to quality and accuracy. This builds public confidence in the lab’s capabilities and the reliability of its test results.

Environmental Protection

Accurate and reliable environmental testing is crucial for identifying and addressing pollution and contamination issues. NELAP-accredited labs guarantee the quality of testing and hence play a crucial role in safeguarding the environment from pollution.

The primary goals of NELAP accreditation are to promote the accuracy and reliability of environmental testing data, ensure laboratories adhere to quality assurance and quality control procedures, and facilitate regulatory compliance. Laboratories that achieve NELAP accreditation are recognized as meeting these high standards and can provide trustworthy environmental testing results that are often required for regulatory compliance, environmental monitoring, and public health protection.

The NELAP Accreditation Process

Achieving NELAP accreditation is a rigorous process that involves several key steps, as listed below:

  1. Application: The laboratory submits an application to the relevant state or agency, outlining its intent to seek accreditation.
  2. Assessment: An assessor or auditing body evaluates the laboratory’s operations, quality control procedures, and staff competency to ensure compliance with NELAP standards.
  3. Onsite Inspection: The laboratory undergoes an onsite inspection where the assessor examines equipment, procedures, records, and staff qualifications.
  4. Data Review: The laboratory’s historical data, quality control records, and proficiency testing results are reviewed to assess the consistency and reliability of its testing.
  5. Accreditation Decision: After a thorough evaluation, the accrediting body makes a decision regarding accreditation. If successful, the laboratory receives NELAP accreditation.

Environmental Laboratory Software Simplifies NELAP Accreditation

Environmental laboratory software, also known as Laboratory Information Management System (LIMS), plays a pivotal role in supporting NELAC and NELAP accreditation for environmental laboratories. Environmental laboratory software streamlines and standardizes data management, ensuring that all testing procedures, results, and quality control measures adhere to the stringent requirements set by these accreditation programs. This not only simplifies the accreditation process but also contributes to the overall efficiency, reliability, and credibility of environmental laboratories.


NELAC and NELAP are instrumental in ensuring the accuracy and reliability of environmental testing conducted by laboratories. These accreditation programs uphold rigorous standards, promote quality assurance, and facilitate regulatory compliance. For environmental laboratories, achieving NELAP accreditation not only enhances their credibility but also contributes to the protection of our environment and public health. Environmental laboratory software simplifies the accreditation journey and enables laboratories to maximize their productivity and upload quality standards seamlessly.
