This blog explores the steps labs can take to prepare for and achieve this esteemed accreditation, solidifying their role as champions of water quality.

What is the TNI/NELAP Accreditation?

The TNI/NELAP accreditation is a comprehensive journey that water testing labs undertake to ensure they meet and exceed industry standards. It serves as a rigorous framework administered by The NELAC Institute (TNI) under the National Environmental Laboratory Accreditation Program (NELAP). This accreditation process involves a thorough evaluation of a laboratory’s technical competence, quality management systems, and adherence to specific standards. Labs seeking accreditation are scrutinized for their overall ability to deliver accurate and reliable results. The accreditation process aims to create a standardized and credible benchmark, strengthening public trust in the capabilities of accredited water testing labs.

How to Prep Your Lab for TNI/NELAP Accreditation?

  1. Read the current NELAP standards: Reading and comprehending the TNI/NELAP accreditation standard serves as the foundational step in preparing your water testing lab for accreditation. It’s the first step to aligning your lab with the industry’s best practices.
  2. Develop a plan: Next, develop a plan for the TNI/NELAP accreditation. The initial step in this process is the creation of a comprehensive Quality Manual or revision of an existing one. This manual offers a clear overview of the laboratory’s quality management system, encompassing policies, objectives, and essential procedures. Whether crafting a new manual or refining an existing one, the goal is to ensure it mirrors the stringent requirements of TNI/NELAP accreditation, providing a guiding reference for all aspects of laboratory activities. Developing the plan also involves a critical evaluation and, if necessary, the updating of both administrative and technical procedures. These procedures are the operational guidelines governing various aspects of laboratory tasks, from sample handling to data management to reporting of test results. Aligning these procedures with TNI/NELAP accreditation standards is crucial to ensuring consistency, accuracy, and compliance.

    Once the groundwork is laid, the implementation phase kicks in which entails developing training programs to equip all personnel with a deep understanding of the revised procedures, emphasizing adherence to testing methodologies and familiarity with the Quality Manual. A robust document control system also needs to be established to manage and track essential documents such as standard operating procedures (SOPs), guaranteeing that the latest versions are readily available to the entire staff.

    Standardized procedures for reporting results need to be put into effect, emphasizing accuracy, consistency, and compliance with regulatory requirements. Furthermore, internal audit procedures are paramount for regularly assessing the effectiveness of the quality management system, identifying areas for improvement, and ensuring ongoing compliance. Lastly, annual management reviews evaluate the overall efficacy of the laboratory’s management system, identifying opportunities for enhancement and ensuring continued alignment with TNI/NELAP standards.

  3. Identify an accreditation body: Determine whether your laboratory’s home state serves as an accreditation body (AB). NELAP-recognized ABs include Florida, Illinois, Kansas, Louisiana, Minnesota, New Hampshire, New Jersey, Oklahoma, New York, Oregon, Pennsylvania, Texas, Utah, and Virginia. If your home state is an AB, you must apply in your home state as your primary AB. If your home state does not serve as an AB, you need to review which AB covers most or all of your Fields of Testing (FOTs).
  4. Schedule the assessment: Scheduling the accreditation assessment is an important step in the preparation process for TNI/NELAP accreditation. It is paramount to plan well in advance to secure a timeframe that aligns with the lab’s readiness and ensures a seamless evaluation process. This proactive approach allows the laboratory to adequately prepare, address any potential concerns, bridge operational gaps, and demonstrate its commitment to meeting accreditation standards. Moreover, ensuring the availability of key personnel, such as the lab director and quality manager, during the assessment is crucial so that the questions can be addressed promptly, and the laboratory’s operations are evaluated accurately.
  5. Gather the required documents and records: In the proactive gathering of required documents and records for the TNI/NELAP accreditation assessment, laboratories should compile a comprehensive set of materials. This includes, but is not limited to, standard operating procedures (SOPs), the Quality Assurance (QA) manual, training records, surveys, quality control (QC) charts, records of assets and instrument maintenance, and documentation of preventive and corrective actions taken. Additionally, labs must secure two sets of passing proficiency test (PT) results for every PT FOT  they seek accreditation for. This thorough documentation not only fulfills accreditation standards but also provides a transparent and detailed overview of the laboratory’s adherence to best practices and commitment to maintaining the highest standards in water testing. Effective communication with the assessor to understand specific document requirements is also crucial in ensuring a comprehensive and successful accreditation assessment.

The Role of a Water LIMS in Achieving and Maintaining NELAP Accreditation

A Laboratory Information Management System (LIMS) plays an important role in addressing TNI/NELAP accreditation requirements, contributing significantly to the accreditation readiness of water testing labs. A LIMS excels in sample scheduling, aligning with Volume 1 Module 2 Section 5.8 of the 2016 edition of the TNI Standard. It provides automatic collection reminders, manages hold times, and ensures compliance with the standards, thereby streamlining the sample handling process. Furthermore, a good water LIMS automates complex calculations crucial in water testing, such as Biological Oxygen Demand (BOD), Total Suspended Solids (TSS), and more. This automation enhances efficiency and minimizes the risk of human error in critical calculations. Not only this, a LIMS excels in automated reporting, addressing Volume 1 Module 2 Section 10 of the TNI/NELAP standards. This feature ensures that the reporting process is streamlined, accurate, and in alignment with accreditation requirements. 

In addition to these TNI/NELAP standard requirements, a water LIMS provides seamless support for equipment calibration and maintenance. It facilitates scheduling of instrument calibration and maintenance and sends alerts ahead of time so that you don’t miss out any scheduled calibration and maintenance. It also serves as a centralized repository for SOPs, QA manuals, training records, and other essential documentation.
