Routine PFAS Testing Services for Water and Soil samples
The EPA uses several methods to detect and manage PFAS in water. Here are the primary methods:
EPA Method 537.1
This method is designed specifically for drinking water and allows the detection of 18 PFAS compounds using solid-phase extraction and liquid chromatography with tandem mass spectrometry (LC-MS/MS). It is commonly used for monitoring PFAS levels in public water systems
EPA Method 533
Finalized in 2019, this method targets short-chain PFAS in drinking water. It complements Method 537.1 by enabling the detection of 25 additional PFAS compounds, including those that are difficult to detect using older methods.
EPA Method 1633
Comprehensive analytical procedure for detecting 40 PFAS compounds in a variety of environmental matrices, including non-drinking water, wastewater, surface water, groundwater, soil, and biosolids. The method uses liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) to provide highly sensitive and specific results, making it one of the most robust methods available for PFAS detection.
EPA Method 1633 in Details
EPA Method 1633 is particularly useful for monitoring PFAS contamination in industrial wastewater and environmental remediation efforts. It plays a critical role in regulatory frameworks, where precise quantification of PFAS levels in diverse media is necessary. This method was finalized in early 2024 and has been extensively validated across laboratories for consistency and accuracy in PFAS detection.
Key Features of EPA Method 1633
Matrices: It can be applied to a range of environmental samples, excluding drinking water. This includes wastewater, surface water, groundwater, soil, and biosolids.
Detection: Capable of detecting 40 individual PFAS compounds, including legacy compounds like PFOA and PFOS, as well as newer replacement PFAS.
High Sensitivity: The method is designed to detect even very low concentrations of PFAS, making it suitable for regulatory purposes and environmental monitoring.

For the expanding range of applications for PFAS testing outside the normal water and soil requirements ProVerde Environmental offers 4 levels of testing solutions
Level 1: Present and detectable
This service is for customers that require a simple answer. Are the most commonly tested PFAS materials present in their product of interest such that when examined they would show PFAS to be present. This may be in Water / Drinks, materials such as packaging, fabrics, cleaning agents or even in food products.
Level 2: Present and to what level
This service is for customers that require a quantifiable result such that they know if it is barely present or present in a larger quantity and which specific PFAS compounds they are. This may be for the product of interest itself or for the components that make up the product of interest to ascertain if there is PFAS present in their supply chain.
Level 3: Method Validation Service
This is for customers that may require PFAS testing on their products of interest and have the required technology but not a Validated method for sample preparation and sample analysis. Oten they may require fast Method development expertise to provide an SOP suitable for less experienced Analysts to do routine testing over required time points.
Level 4: PFAS Certification Services
This is for customers that may require help with Certification to support claims that their products are either “PFAS free’ or below detectable limits of quantitation for commonly held limits such as EPA method limits.
