PFAS, Dioxins, and Quaternary Ammonium Compounds (QACs)
Precision testing for emerging and persistent contaminants.
Looking for reliable specialty environmental testing?
SPL offers industry-leading analysis for high-impact contaminants like PFAS (Per- and Polyfluoroalkyl Substances), Dioxins and Furans, and QACs (Quaternary Ammonium Compounds). Our advanced testing services are designed to support compliance, environmental risk assessment, and remediation efforts—backed by 80+ years of trusted laboratory expertise.
PFAS Testing Services
Test for “forever chemicals” with confidence.
PFAS compounds are resistant to heat, water, and oil—and they’re found in everything from firefighting foam to consumer products. These “forever chemicals” accumulate in the environment and the human body, making accurate testing essential for regulatory compliance and public safety.
Key Features:
Use Cases: Site remediation, water utility monitoring, industrial discharge
EPA Methods: 533, 537.1, 1633
Matrix Coverage: Drinking water, groundwater, wastewater, soil, air, biosolids
Detection Limits: Low ppt (ng/L)
Instrumentation: LC-MS/MS with trace-level sensitivity


Dioxin and Furan Testing
Ultra-trace testing for high-toxicity pollutants.
Dioxins and furans are among the most toxic chemicals regulated globally. SPL provides high-resolution GC-MS testing to detect and quantify dioxins in air, soil, water, and waste with precision.
Key Features:
- EPA Method: 1613B
- Detection Limits: Sub-ppt (pg/L or pg/g)
- Sample Types: Stack emissions, ash, biosolids, sediment, industrial soil
- Applications: Hazardous waste permitting, environmental forensics, incinerator testing
Quaternary Ammonium Compounds (QACs) Testing
Analyze disinfectant and antimicrobial residues in environmental samples.
QACs are widely used in personal care, cleaning products, and industrial disinfectants—but they can persist in wastewater and surface water, posing environmental and regulatory concerns.
Key Features:
Applications: Effluent monitoring, regulatory compliance, product impact studies
Analytes: BACs, DDACs, ATMACs, and more
Detection Method: LC-MS/MS
Detection Limits: Low ng/L (ppt)
Sample Types: Wastewater, surface water, sediment, biosolids, rinse waters
