Drinking Water Testing and Analysis
Accredited analysis for public water systems, municipalities, engineering firms, and private well owners. Backed by 60+ years of drinking water expertise.
SPL’s drinking water testing program was built on one of our organization’s founding services and remains a core capability across our laboratory network. We provide comprehensive analysis of drinking water samples including microbiology, inorganic contaminants, organic contaminants, metals, and radiologicals, serving public water suppliers, municipalities, engineering firms, contract operators, consulting firms, and environmental laboratories nationwide. Our laboratories hold NELAP/TNI certification and state-specific drinking water certifications, delivering accurate, defensible data that meets the highest standards of regulatory compliance and public health protection.
Comprehensive Drinking Water Analysis
We accept samples of all types and provide full-spectrum analysis to meet your compliance and operational needs.
Microbiology
Inorganic Chemistry and Metals
Organic Chemistry
Specialty Testing - PFAS
Total coliform, E. coli, heterotrophic plate count, and other microbial indicators required for public water system compliance and distribution monitoring.
Nitrates, nitrites, fluoride, arsenic, lead, copper, iron, manganese, and a full suite of regulated and non-regulated metals and inorganic parameters.
Analysis for cancer causing chemicals such as volatile organic compounds (VOCs), synthetic organic compounds (SOCs), disinfection byproducts (DBPPs).
PFAS analysis using EPA Methods 533, 537.1, and 1633 across potable water, non-potable water, soil, and solid waste matrices. As regulatory standards continue to evolve, our laboratory stays current with EPA method updates and detection requirements.
Built for Every Type of Drinking Water Client
Public Water Suppliers & Operators
Engineering & Consulting Firms
Protecting public health is at the core of what you do, and our team understands what’s important – defensible data you can trust. Our dedicated project managers guide you from your first sample submission through the life of our relationship.
SPL has been a trusted partner to engineering firms and consulting companies for decades. We deliver fast turnaround, reliable data, and project management support that keeps your project on schedule and your clients confident.
Environmental Laboratories
Private Well Owners
Need capabilities you don’t have in-house? SPL functions as a reference and overflow laboratory for environmental labs that need to expand their analytical scope without expanding their footprint. We deliver your clients’ results with the same reliability and accreditation you’d expect from your own facility.
Concerned about what’s in your well water? SPL offers private well testing to help homeowners understand their water quality and make informed decisions about treatment and safety. Contact us to discuss your testing needs and order a sampling kit.
Accreditation and Data Quality
When it comes to public health, data quality isn’t optional. SPL’s entire team operates under a personal commitment to defensible data — reviewed at multiple levels before it ever reaches you.
Every result goes through analyst review, a second-level approval by a Quality Specialist, and a final check by your Project Manager. We know our data is used to make decisions that affect communities and public health. That’s why we get it right the first time.

What drinking water contaminants does SPL test for?
SPL provides comprehensive drinking water analysis including microbiology (total coliform, E. coli, heterotrophic plate count), inorganic contaminants, metals (lead, copper, arsenic, nitrates), organic contaminants (VOCs, SOCs, disinfection byproducts), PFAS, and radiological parameters. We accept all sample types and can test for both regulated and non-regulated parameters.
Does SPL serve my state?
SPL operates a growing network of more than 40 laboratory locations across the U.S., with continued expansion underway. Please contact our team directly at info@spllabs.com or visit our Locations page to find the lab closest to you. Our locations also serve clients across surrounding states.
Can SPL report directly into my state's compliance reporting system?
Yes. SPL uses automated LIMS integration to upload results directly into state compliance reporting systems, eliminating manual data entry and reducing human error. This is particularly valuable for public water suppliers who face regulatory deadlines for compliance reporting.
Does SPL provide drinking water testing for private wells?
Yes. SPL offers private well testing for homeowners and property owners who want to understand what contaminants may be present in their water supply. Contact our team to discuss appropriate testing panels and sample collection options for your situation.
How long has SPL been certified for drinking water testing?
SPL has held continuous drinking water laboratory certification since certification programs became available in the 1970s — giving us more than 60 years of uninterrupted accredited experience in drinking water analysis.
What is NELAP accreditation and why does it matter for drinking water testing?
NELAP (National Environmental Laboratory Accreditation Program) is the national standard for environmental laboratory accreditation, administered through TNI (The NELAC Institute). A NELAP-accredited laboratory has demonstrated that its testing methods, equipment, personnel, and quality systems meet rigorous national standards — ensuring that the data it produces is technically defensible and legally admissible for regulatory compliance purposes.
