Hazardous Liquid Waste Sampling from Tanks

Sampling and Testing Process

1. Preparation of Sampling Plan and Approvals:
   • Sampling plan according to Ministry of Environmental Protection guidelines
   • Client approval and authorization from the Hazardous Materials Division
2. Coordination and Pre‑Sampling Preparation:
   • Scheduling sampling dates
   • Notifying the Ministry of Environmental Protection
   • Pre‑site survey and preparation of calibrated sampling equipment
3. Field Sampling Execution:
   • Sampling performed in a controlled order from the least to most contaminated areas, according to the approved plan
4. Safety and Documentation:
   • Strict adherence to safety procedures and site requirements
   • Completion of designated forms for liquid waste sampling from tanks
   • Comprehensive documentation of sampling conditions
5. Sample Preservation and Transport:
   • Storage under controlled cooling conditions
   • Transport to the laboratory under chain‑of‑custody protocol
6. Accredited Laboratory Analysis:
   • Conducting required analyses at the company’s accredited laboratory
7. Hazard Classification (upon request):
   • Determination based on analytical results
8. Final Report:
   • Preparation of a detailed report including results and recommendations for further actions

Sampling Methods and Types

We perform all required sampling methods (grab, composite, and representative) for hazardous liquid waste from tanks, in accordance with the waste type and its storage configuration:

• Sampling from small tanks – handling liquid waste in tanks up to 1,000 liters
• Sampling from medium tanks – handling liquid waste in tanks of 1,000–10,000 liters
• Sampling from large tanks – handling liquid waste in tanks exceeding 10,000 liters
• Sampling from tanks with mixing systems – adapting sampling protocols for mixing tanks
• Sampling from layered tanks – multi-layer sampling to identify phase separation

Frequently Asked Questions

• Why is it important to perform hazardous liquid waste sampling from tanks?
  • To characterize the waste composition, identify hazardous contaminants, comply with Ministry of Environmental Protection requirements, and determine the hazard level for proper treatment, disposal, or transport.
• Who is authorized to perform hazardous liquid waste sampling?
  • Certified samplers who have completed full training in accordance with Ministry of Environmental Protection guidelines and operate under ISO 17025 accreditation, together with an accredited analytical laboratory.
• How is the sampling process carried out in practice?
  • Through an approved sampling plan, a preliminary site visit, controlled sampling performed in a defined sequence (from the least contaminated to the most contaminated), full documentation, appropriate sample storage, and transport under a documented chain of custody.
• Which types of tanks can be sampled?
  • Small tanks (up to 1,000 liters), medium tanks (1,000–10,000 liters), large tanks (over 10,000 liters), mixing tanks, and multi-layer tanks requiring phase-specific sampling.
• Which sampling methods are used for hazardous liquid waste?
  • Grab, composite, and representative sampling, depending on the sampling plan, waste characteristics, and tank storage configuration.
• How are samples preserved until they reach the laboratory?
  • Through storage under appropriate cooling conditions, completion of designated documentation forms, full traceability of all sampling stages, and controlled transport to maintain sample integrity.
• What does the final report provided to the client include?
  • Complete analytical results, hazard classification (upon request), professional assessments, and recommendations for further handling based on the findings.
