The Reading Lab. Local Expertise, National Depth.
SPL’s Reading, Pennsylvania laboratory is the headquarters of what was formerly Suburban Testing Labs — one of the most recognized independent environmental testing labs in the Mid-Atlantic. Since the rebranding to SPL in September 2025, the Reading facility operates as a full-service facility within SPL’s national network of 30+ locations, backed by the same team, the same quality standards, and expanded capabilities.
Located at 1037F MacArthur Road in Reading, PA, this laboratory processes samples 365 days a year. Our scientists understand the regulatory requirements that govern compliance work in Pennsylvania and the surrounding region, from PADEP Safe Drinking Water programs to NJDEP and MDDEP discharge permits, and they deliver results with the turnaround times and chain-of-custody documentation that regulatory submissions require.
Whether you are a public water supplier, a wastewater treatment plant, an environmental consultant, or a municipality managing a remediation site, the Reading lab is equipped to support your program from routine compliance testing through complex emerging contaminant analysis.
What We Test
Drinking Water and Potable Water
Comprehensive analysis for public water suppliers, community systems, and non-transient non-community water systems. Covers inorganic and organic parameters, microbiological testing, disinfection byproducts, and compliance monitoring under the Safe Drinking Water Act. Public Water Supply compliance data is submitted in formats accepted by state and/or federal programs.
Wastewater
NPDES permit compliance testing, EPA Industrial Pretreatment Program (IPP) analysis, and whole effluent toxicity for municipal and industrial dischargers. Biosolids and sludge characterization, including microbiology, heavy metals, nutrients, and emerging contaminants. Our wastewater clients include POTWs, industrial facilities, and consulting engineers managing permit applications and renewals.
Groundwater and Stormwater
Site assessment and remediation support for environmental engineers, consultants, and construction projects, including Phase II environmental investigations, underground storage tank programs, and long-term monitoring. Stormwater compliance under industrial general permits and MS4 programs.
Soil and Solid Materials
Inorganic and organic analysis for site assessment, waste characterization, and disposal compliance. Biosolids, sludge, grit, and solid waste testing for land application and permitting programs. Includes underground storage tank investigation support and hazardous waste screening.

Specialty Testing: What Sets Reading Apart
PFAS: All Three EPA Methods, In-House
Per- and polyfluoroalkyl substances (PFAS) are among the most heavily regulated emerging contaminants in the country, and compliance requirements are accelerating across the Mid-Atlantic. SPL Reading performs PFAS analysis using all three current EPA methods — in-house, without shipping samples to an out-of-state facility.
EPA Method 537.1
Drinking water analysis for PFOA, PFOS, PFNA, PFHxS, HFPO-DA (GenX), and PFBS. Used for public water supplier compliance monitoring under PADEP and the EPA PFAS National Primary Drinking Water Rule.
EPA Method 533
Drinking water analysis covering a broader range of PFAS compounds, including short-chain PFAS not captured by Method 537.1. Achieves minimum reporting levels of 5 ppt and below, supporting reduced monitoring eligibility determinations.
EPA Method 1633
Multi-matrix method covering PFAS in non-potable water, soil, biosolids, and solid materials. SPL Reading holds accreditation for Method 1633 in all applicable matrices, including solids and biosolids.
Keeping samples local matters. Shipping PFAS samples introduces chain-of-custody risk, temperature management variables, and turnaround delays that affect your ability to meet regulatory deadlines. When you submit to SPL Reading, your samples stay in Pennsylvania, handled by scientists who know your compliance program.
EPA Method 1613, Accredited In Pennsylvania
Dioxin analysis in drinking water has historically required Pennsylvania labs and water systems to ship samples to facilities in California, Tennessee, or Minnesota, adding days to turnaround and introducing shipping risk on one of the most analytically sensitive methods in environmental testing.
SPL Reading changed that. Our laboratory holds in-state accreditation for Dioxin analysis in drinking water using EPA Method 1613, performed via high-resolution gas chromatography with high-resolution mass spectrometry (HRGC/HRMS). This method detects 2,3,7,8-TCDD and related congeners at the lowest reportable levels required for regulatory compliance.
For public water suppliers, consulting engineers, and industrial clients who need Dioxin results without the delay and cost of long-distance shipping, SPL Reading is the only option that keeps your samples and your data in Pennsylvania.
Accreditation and Certifications
SPL Reading holds accreditation in accordance with the National Environmental Laboratory Accreditation Program (NELAP/TNI) for drinking water, non-potable water, and solid and chemical materials. State-specific certifications support compliance submissions across the following jurisdictions:
- Pennsylvania (PADEP, Chapter 252)
- New Jersey (NJDEP)
- Maryland (MDE)
- Delaware (DNREC)
- New York
- Texas
- Colorado
- Additional states — contact us to confirm coverage for your project
Because accreditation scope varies by matrix and analyte, we recommend reaching out before submission to confirm specific certification coverage for your regulatory program.
SPL’s quality system applies three independent review levels to every result: analyst review, technical review, and project manager review before data leaves the laboratory. Every data package is checked against method-specific QC requirements before delivery.
Accreditation scope, method lists, and holding time requirements are available on request. Contact reading.info@spllabs.com.
Public Water Suppliers
Community water systems, non-transient noncommunity systems, and transient systems managing compliance monitoring under the Safe Drinking Water Act. From routine inorganic/organic compliance through PFAS initial monitoring and quarterly sampling, SPL Reading supports your reporting calendar with turnaround times and data formats accepted by PADEP.
Wastewater Treatment Plants
Municipal POTWs and industrial dischargers with NPDES permits, pretreatment programs, and biosolids land application approvals. Our wastewater scientists understand permit limits and help you stay in front of new requirements before they become enforcement issues.
Environmental Consultants and Engineers
Phase I/II site assessors, remediation project managers, and consulting engineers who need a lab partner that returns defensible data on time and answers questions directly. SPL Reading project managers are reachable by phone and email and do not operate through a call center.
Industrial and Manufacturing Facilities
Facilities with permits, industrial pretreatment obligations, and waste characterization requirements. Specialty testing for emerging contaminants including PFAS, Dioxin, and Quaternary Ammonium Compounds in complex matrices.
Municipalities and Government Agencies
Local governments managing compliance programs, infrastructure projects, and environmental remediation. SPL data packages are formatted for regulatory submission and legal proceedings.
Subcontract Laboratories
Laboratories supporting the testing needs of their clients don’t always offer everything their client needs. That’s where a partnership with SPL comes in. Analysis for synthetic organic compounds (SOCs), Dioxin, PFAS, and more will be handled with the utmost care and dedication to quality, defensible data.
