Quality Management Plan (QMP) for Environmental Sampling Procedures

The Environmental Department's QA program guidelines as per USEPA Region II requirements. Includes QAPP functions, data validation, sample custody, potential errors, methods of preservation, sample cooling, and more. Ensure accurate field sampling and analysis.

  1. Just Get Out ThereAnd Sample!

  2. Quality Management Plan(QMP) • The Department is required by USEPA Region II to develop and maintain a QA program • QMP prepared and approved every two years • Defines Department’s QA program

  3. QAPP Functions • Communicate • Summarize • Document • Audit

  4. QAPPs are Written in Accordance With: “Guidance on Quality Assurance Project Plans (QA/G-5),” February, 1998, USEPA

  5. Data Usage • Permits • Enforcement • Research

  6. Elements in ProvidingQuality Assurance • QAPP • SOP • Certification Programs • P.T. Samples • Data Validation • Audits - Lab and Field

  7. Data Quality Requirements • Method Options • Laboratory Specific MDLs

  8. Take Samples and Preserve in the Field • Deliver samples to lab within holding time • “Analyze Immediately” parameters must be done within fifteen minutes, i.e. DO, pH, TRC, Temp, sulfite

  9. Holding Times • USEPA sets holding times • Outlined in 40 CFR • N.J.A.C. 7:18 regulations • Department field sampling procedures manual

  10. Sample Containers • Container must not react with sample • Plastic containers - best for inorganic parameters • Glass containers - best for organic parameters (teflon lined caps) • Sterile container - required for microbiological

  11. Methods of Preservation • Acids control pH, keep metal ions in a dissolved state, and control biological action • If Chlorine is present, add a reducing agent (ascorbic acid, sodium thiosulfate) • Refrigerate at 4o C • Freezing - tissues (fish, birds)

  12. Sample Cooling • Blue ice is discouraged. It does not generally maintain the temperature of the sample at 4o C or less. • If using blue ice, it should be frozen at the time of use, and samples should be at 4o C before packing with it

  13. Sample Custody • Chain-of-custody record used for sample transfers • Each sample transfer documented with signature, date, and time • Sample access and handling controlled and documented

  14. Potential Errors inSampling and Analysis • Taking samples at location or times that do not accurately represent the quality of the groundwater or effluent being sampled

  15. Potential Errors inSampling and Analysis • Using equipment made of inappropriate material that may react with samples and contaminate them

  16. Potential Errors inSampling and Analysis • Using sampling equipment that is not decontaminated prior to sampling and between sampling episodes

  17. Six Phases of a Project • Enthusiasm • Dillusionment • Panic • Search for the Guilty • Punishment of the Innocent • Praise and Honor for the Nonparticipants
