The Standard in Environmental Laboratory Testing Excellence
One accredited laboratory relationship covering the environmental matrix your compliance program requires.
Water and Wastewater
Comprehensive testing for drinking water, wastewater, groundwater, and stormwater — including Public Water Supply compliance, NPDES analysis, EPA Industrial Pretreatment Program testing, and site remediation support.
Soil and Solid Waste
Inorganic, organic, and soil quality analysis for site assessment, remediation, and waste management. Includes biosolids microbiology, sludge and grit analysis, waste characterizations, and underground storage tank investigation support.
Specialty Testing
Advanced testing for complex and emerging contaminants including PFAS (EPA Methods 533, 537.1, and 1633), Dioxin (2,3,7,8 TCDD), Quaternary Ammonium Compounds, and illicit drug screening across potable water, non-potable water, soil, and solid waste matrices.
Field Sciences
In many service regions, SPL field technicians handle sample collection of water, wastewater – grab and composite, and solid materials following strict chain-of-custody protocols. Trained staff ensure sample integrity and regulatory compliance from collection through laboratory delivery.
The Standard in Laboratory Testing Excellence
At SPL, environmental testing is not a commodity service — it is a scientific and regulatory responsibility. Every sample that enters our laboratories represents a real decision about public health, environmental compliance, or community safety. That is why we have built our environmental program around three things your operation cannot compromise on.
- Results You Can Defend - Multi-level data review by analysts, Quality Specialists, and your dedicated Project Manager — so your data is correct the first time, every time.
- Dedicated Project Management - You are assigned a dedicated Project Manager from project kickoff through the life of your account — your single point of contact for results, compliance tracking, and reporting.
- Fast Turnaround Without Compromise - We prioritize speed without sacrificing quality. Four delivery options — automatic email, online access, fax, or hardcopy — configured to your workflow from day one.
