Mastering EPA Method 1633: Overcoming PFAS Data Complexity

SPW — Mon, 13 Apr 2026 16:46:16 +0000

Laboratories working in water and wastewater analysis face more challenges than ever before. With increased regulatory scrutiny around “forever chemicals” like PFAS (per- and polyfluoroalkyl substances), accurate, audit-ready results are essential. EPA Method 1633, which is specifically for PFAS analysis in non-potable water, has raised the bar—but also the complexity.

For lab teams, managing data for more than 40 PFAS compounds per sample (plus, a high volume of samples), represents a significant strain. That strain is amplified for teams who rely on outdated methods like manual data entry or spreadsheet-based systems.

So, how can labs clear these hurdles? How can they master EPA Method 1633? Let’s explore how BTSOFT’s purpose-built laboratory software can transform PFAS data management.

Why EPA Method 1633 Is So Complex

EPA Method 1633 is designed to monitor the presence of PFAS in wastewater. This regulation demands precise reporting for over 40 individual compounds. That’s a demanding task for even the most skilled environmental labs.

Each sample needs careful tracking. From preparation and analysis to data recording and reporting, doing this manually and/or done via spreadsheets is error-prone and inefficient. One missed entry can mean non-compliance or a failed audit, risking both reputation and regulatory standing.

PFAS Testing

The Growing Need for Accurate Analysis

High sample volumes, sometimes hundreds per day, translating to thousands of individual data points.
Detailed record-keeping requirements, including parameters, hold times, and chain-of-custody documentation.
Anxiety around audit readiness, especially when data is scattered across files and manual notes.
Regulatory demands that leave no room for error, delays, or missed details.

Yes, these represent a challenge to your lab’s efficiency, but they can also represent a landmine and cause your lab to lose trust with clients and regulators.

So, what can you do?

How a Modern LIMS Solves EPA Method 1633 Data Management

Environmental and wastewater labs face unique challenges in managing data for EPA Method 1633, given the large number of analytes, strict regulatory requirements, and the need to maintain audit-ready records. A modern Laboratory Information Management System (LIMS) can fundamentally transform how labs approach these challenges.

Automated Data Capture

LIMS automate the process of capturing data directly from laboratory instruments, eliminating the need for manual data entry and transcription. This not only reduces the risk of human errors commonly associated with spreadsheets, but also ensures that all results for the 40+ PFAS compounds are accurately mapped to the appropriate samples. Data can flow into the system, where it is automatically validated against method specifications. In practice, this looks like a dashboard view, where analysis files are uploaded or automatically imported, and results are instantly available for review, minimizing turnaround time and maximizing data integrity.

Automating EPA Reporting

Why Environmental Labs Trust LIMS

Customizable and Rapid Reporting

With a LIMS, report generation becomes fast and flexible. Labs can configure reports to comply not only with federal EPA requirements, but also local or permit-specific stipulations. Instead of spending hours assembling results and narrative in spreadsheets or word processors, automated templates can compile compliant reports at the click of a button. This means faster delivery of results to clients and less risk of missing a critical compliance detail.

Audit-Ready Trails and Data Integrity

Regulatory compliance means being able to track every action performed on your data. In a LIMS, every action—be it data entry, edits, reviews, or approvals—is logged with time stamps and user credentials. This creates a complete chain-of-custody and data audit trail that is easily accessible in the event of an audit or regulatory review. Labs benefit from increased security and peace of mind, knowing their records can stand scrutiny.

Elimination of Manual Entry and Centralized Data Management

Manual entry into spreadsheets or disparate databases increases the likelihood of errors and inefficiencies. LIMS centralize all analysis, QC, and client information into a single, secure platform. Results, documentation, and chain-of-custody records are all stored together, streamlining workflow and making information retrieval quick and reliable.

Client Transparency

With LIMS, you can offer secure client portals, giving clients real-time access to results and compliance records. This not only improves transparency but also builds trust, as clients can directly view sample progress and access finalized reports without delay.

Ensuring EPA Water Quality Standards

SPW — Wed, 28 Feb 2024 08:00:00 +0000

Water quality standards, set by the Environmental Protection Agency (EPA), are essential for defining and maintaining bodies of water and protecting public health and the environment. Laboratories play a critical role in ensuring compliance with these standards through accurate testing and analysis. Let’s go over the water quality standards, the importance of laboratory accreditation and quality control measures, and the benefits of using a Laboratory Information Management System (LIMS) for meeting EPA water quality standards.

Learn More about the 5-Phase Roadmap to LIMS Implementation

EPA Water Quality Standards Overview

The Environmental Protection Agency (EPA) is responsible for establishing water quality standards (WQS) to define the desired condition of water bodies and the acceptable levels of pollutants in those bodies of water. These standards are regulations set by states and authorized tribes and may vary depending on local situations and designated uses.

EPA water quality standards are crucial for the protection of public health and the environment. They provide a framework for assessing and managing water quality and enabling effective decision-making on water resource management. The EPA works closely with states and other stakeholders to develop and implement these standards.

Examples of Water Quality Standards

1. Maximum Contaminant Levels (MCLs)

MCLs define the maximum allowable concentrations of specific contaminants in drinking water. For instance, the EPA has set an MCL of 0.015 milligrams per liter (mg/L) for lead in drinking water.

2. Total Maximum Daily Load (TMDL)

A TMDL is the maximum amount of a pollutant that a water body can receive while still meeting water quality standards. It takes into account both point-source and nonpoint-source pollution. States establish TMDLs to address impaired water bodies and develop plans to reduce pollutant loads to achieve water quality goals.

3. Numeric Criteria

Numeric criteria specify the desired levels of pollutants in water bodies to protect aquatic life and human health. For example, states may set numeric criteria for dissolved oxygen levels, temperature, pH, and specific pollutants such as nutrients or heavy metals.

4. Designated Uses

Water bodies are classified based on their intended uses, such as drinking water supply, swimming or recreational activities, and protection of aquatic habitat. Different standards and criteria are set based on these designated uses to ensure the water quality matches the specific requirements.

The National Primary Drinking Water Regulations encompass water quality standards.

Development of EPA Water Quality Standards

The EPA develops water quality criteria to protect human health and aquatic life and provides guidance to states adopting and/or maintaining water quality standards. These criteria consider various factors, such as the chemical, physical, and biological characteristics of water, as well as the designated use of the water body, such as drinking water supply, recreational activities, and aquatic habitat preservation.

To ensure the provision of safe drinking water, water quality standards encompass the National Primary Drinking Water Regulations, established under the Safe Drinking Water Act. These regulations establish legally enforceable standards and treatment techniques for public water systems to safeguard public health by restricting contaminant levels. They define maximum contaminant levels (MCLs) for substances like bacteria, lead, arsenic, and disinfection byproducts found in drinking water. These standards specify maximum contaminant levels (MCLs) for various substances in drinking water, such as bacteria, lead, arsenic, and disinfection byproducts.

Enforcing compliance with these standards is crucial to safeguarding public health and ensuring the provision of safe drinking water to communities.

To prove the accuracy of their testing, laboratories often seek accreditation from recognized bodies such as the National Environmental Laboratory Accreditation Program (NELAP) or certification from EPA-approved certification programs. These programs evaluate the laboratory’s technical competence, quality management systems, and adherence to standard operating procedures.

Quality Assurance/Quality Control

In order to maintain accuracy and reliability, laboratories follow quality assurance and quality control protocols. These include regular calibration of laboratory equipment, participation in proficiency testing programs, and adherence to strict quality control measures throughout the analytical process.

Sampling and Analysis

Sampling and analysis play a crucial role in guaranteeing accurate test results. Laboratories follow precise procedures for collecting samples from water sources, ensuring sample preservation, and employing methods for detecting contaminants.

Sample Collection and Preservation

Laboratories must follow the EPA’s sampling protocols to uphold the integrity of the samples. This includes proper sterilization of sampling containers, collecting proper sample volumes, and transporting samples to the laboratory while maintaining the required temperature and conditions.

Analytical Methods

Laboratories employ a range of analytical methods approved by the EPA for the detection and quantification of contaminants in water. These methods may involve various steps, such as sample preparation, extraction, and instrumental analysis using techniques like chromatography, spectroscopy, or mass spectrometry. Laboratories must validate their analytical methods and participate in method performance tests to ensure accurate and reliable results.

LIMS (Laboratory Information Management Systems) are essential for meeting EPA standards.
