Site Remediation and Waste Disposal Laboratory Testing
SPL delivers accredited site remediation laboratory testing for waste characterization, TCLP and SPLP determinations, brownfield investigations, UST programs, contaminated soil assessment, and regulatory compliance decisions. Our dedicated project managers guide every project from first sample through final closure.
SPL provides comprehensive site remediation laboratory testing and waste disposal analytical services. Because our NELAP/TNI-accredited laboratories hold state certifications in the states across our growing network, we deliver accurate, defensible data for groundwater, soil, solid waste, leachate, and non-potable water matrices. We support environmental consultants, engineering firms, remediation contractors, industrial facility owners, municipalities, and property developers through every phase of site investigation, waste determination, and regulatory closure. Furthermore, our dedicated project managers coordinate analytical programs of every scale, from single-sample TCLP determinations to multi-year remediation monitoring programs, so your project stays on schedule and your data holds up under regulatory scrutiny.
How SPL Protects Your Data Integrity
Under RCRA and applicable state regulations, the difference between a hazardous and non-hazardous waste determination is not just a laboratory result. It determines where material can be disposed, what it costs to dispose of it, and what liability exposure follows the generator if the characterization is wrong. A TCLP result that misclassifies a hazardous waste as non-hazardous can result in improper disposal, regulatory enforcement, and remediation costs that dwarf the original project budget. SPL’s multi-level data review process and NELAP accreditation are specifically designed to produce waste characterization data that withstands regulatory scrutiny.

Analytical Services for Every Phase of Your Project
TCLP and Waste Characterization
Toxicity Characteristic Leaching Procedure testing by SW-846 Method 1311 for hazardous versus non-hazardous waste determination under RCRA. SPL also performs Synthetic Precipitation Leaching Procedure (SPLP) and supports multi-method characterization programs where regulatory requirements call for additional analysis beyond standard TCLP.
Solid and Chemical Waste Analysis
Characterization of industrial wastes, construction and demolition debris, excavated materials, and specialty waste streams for disposal determination and regulatory compliance. SPL supports ignitability, corrosivity, reactivity, and toxicity characteristic testing under RCRA Subtitle C requirements.
Contaminated Soil Analysis
Full suite of soil analytical services for site investigations, remediation verification, and waste characterization, including VOCs, SVOCs, metals, TPH, pesticides, PCBs, and PFAS. SPL supports state-specific method requirements for soil programs in various states where we hold accreditations.
Leachate Analysis
Routine leachate characterization and compliance testing for landfill operations, treatment system monitoring, and disposal program support. Parameters include metals, organics, conventional parameters, nutrients, and emerging contaminants including PFAS using EPA Methods 533, 537.1, and 1633.
Groundwater and Monitoring Well Analysis
Detection monitoring, assessment monitoring, and corrective action verification sampling for contaminated sites, UST programs, brownfield investigations, and long-term remediation monitoring programs. Custom EDD formats automated from our LIMS for regulatory submission.
Spill Response and Emergency Sampling
Time-sensitive analytical support for spill response and emergency environmental investigations requiring fast turnaround and rapid data delivery. SPL project managers coordinate priority scheduling and communicate results as analysis is completed.
From Site Assessment Through Long-Term Compliance
SPL supports site remediation laboratory testing at every stage of the environmental project lifecycle. Because project needs change as sites move from investigation through remediation to closure, your dedicated project manager stays with the program throughout, adapting analytical scope and reporting formats as requirements evolve.

Results When Your Project Needs Them
Remediation projects move on schedules set by regulators, site owners, and remedial system performance. Consequently, your site remediation laboratory testing data must keep pace with those demands. SPL therefore delivers results through real-time online access as analysis completes, automatic email or fax delivery of final reports, and custom Electronic Data Deliverables formatted to your exact project and state agency specifications. Furthermore, data packages for regulatory review and submission are automated directly from our LIMS. Because disposal decisions and regulatory deadlines cannot wait, your data is available the moment analysis is complete.

Frequently Asked Questions
What is TCLP testing and when is it required?
TCLP stands for Toxicity Characteristic Leaching Procedure, performed by EPA SW-846 Method 1311. It is used to determine whether a solid waste exhibits toxicity characteristics that would classify it as hazardous under RCRA. The test simulates conditions present in a municipal solid waste landfill by extracting contaminants from a waste sample using a leaching fluid, then analyzing the resulting leachate for regulated metals and organics. TCLP is required whenever a waste generator needs to demonstrate that material meets non-hazardous waste disposal criteria before it can be accepted at a municipal or construction and demolition landfill.
What is the difference between TCLP and SPLP?
TCLP (Method 1311) uses an acetic acid leaching fluid designed to simulate conditions in a municipal solid waste landfill co-disposal scenario and is used for RCRA hazardous waste determination. SPLP (Method 1312) uses a sulfuric and nitric acid leaching fluid designed to simulate acidic precipitation percolating through a waste pile and is used to evaluate the potential for contaminants to leach into groundwater or surface water under actual field conditions. Both tests evaluate the mobility of contaminants from solid materials, but they answer different regulatory questions. SPL performs both methods and can advise on which is appropriate for your project.
Can SPL handle high-frequency sampling for active remediation projects?
Yes. SPL supports high-frequency analytical schedules including daily analysis for active treatment monitoring, spill response, and other time-sensitive project phases. Your dedicated project manager coordinates the schedule and ensures turnaround commitments are met throughout the project.
Does SPL provide sampling kits for self-samplers?
Yes. SPL prepares sampling kits in coolers with all necessary sample containers and preservatives, pre-filled chain of custody forms, and sample labels at no additional charge. This saves your field staff time on every sampling event and ensures samples arrive at the laboratory in the correct condition for analysis.
Does SPL provide custom Electronic Data Deliverables for regulatory submissions?
Yes. SPL project managers configure EDDs to your exact project and state agency specifications, automated from our LIMS. Data packages for regulatory review and submission are formatted to the requirements of your specific program including PADEP, NJDEP, MDE, and other state agency formats.
What certifications does SPL hold for site remediation and waste testing?
TCLP (Method 1311) uses an acetic acid leaching fluid designed to simulate conditions in a municipal solid waste landfill co-disposal scenario and is used for RCRA hazardous waste determination. SPLP (Method 1312) uses a sulfuric and nitric acid leaching fluid designed to simulate acidic precipitation percolating through a waste pile and is used to evaluate the potential for contaminants to leach into groundwater or surface water under actual field conditions. Both tests evaluate the mobility of contaminants from solid materials, but they answer different regulatory questions. SPL performs both methods and can advise on which is appropriate for your project.
