CAL Annual Conference Technical Sessions, November 19, 2020

Time:  11:00 – 11:15 AM

Opening by Dr. David Kimbrough, PhD, CAL President

Time:  11:15 – 11:55 AM

Presentation Title:  Regulatory Update

Name of Presenter:  Amber Baylor

Organization:  SOCWA

Email:  abaylor@socwa.com

General update on the state of ELAP and regulations and other related regulations.

Time:  12:00 – 12:50 PM

Presentation Title:  Internal Assessments with a Focus on Small Labs

Name of Presenter:  Bill Ray

Organization:  William Ray Consulting, LLC

Email:  bill_ray@williamrayllc.com

One-hour training session covering how a small lab can conduct required internal audits specified by TNI standards.  The focus will be on tools and checklists to generate objective evidence.  The goal is to get around internal assessments consisting of internal monologs.  All participants will receive a certificate showing CEUs earned.

Time:  1:00 – 2:50 PM

Presentation Title:  Data Integrity and Ethics

Name of Presenter:  Bill Ray

Organization:  William Ray Consulting, LLC

Email:  bill_ray@williamrayllc.com

Two-hour training session covering ethics, ethical behavior and data integrity for all staff involved with laboratory analyses. The training will cover topics on ethical decision-making when conducting sample collection and sample analyses; proper recordkeeping to create chains of records covering actual analyses and link to support documents; and examples of situations were unethical behavior germane to laboratory procedures. All participants will receive a certificate showing CEUs earned.

Time:  3:00 – 3:50 PM                   

Presentation Title: Moving to a LIMS to Help Meet CA ELAP Requirements

Name of Presenter: Rick Danielson, PhD

Organization:  Accelerated Technology Laboratories, Inc

Email: rdanielson@atlab.com 

The California Environmental Laboratory Accreditation Program (ELAP) is undergoing significant

changes including the adoption of The NELAC Institute (TNI) requirements for accredited laboratory operation. This has many ELAP-accredited laboratories considering upgrading to a LIMS to

address many of the ELAP requirements. This presentation will highlight some of the upcoming challenges of meeting TNI-based requirements and how a LIMS can help in meeting these challenges. In addition to increasing productivity and efficiency, a LIMS provides automated documentation and traceability, two key areas of the TNI requirements. Attendance is a must for those considering taking on TNI with only spreadsheets and word processing.

Time:  4:00 – 4:30 PM

Presentation Title:  A New Approach: Using Mathematical Equation to Accurately Determine Appropriate Sample Volumes for BOD Analysis

Name of Presenter:  Dennis Zheng

Organization:   SUEZ

Email:  dennis.zheng@suez.com

Choosing an appropriate range of sample volumes to produce valid BOD analysis is necessary and important because of a short sample holding time (2 days), a long period of incubation (5 days), and an inability to repeat tests and still meet regulatory compliance standards. For samples from sites not routinely monitored, the previous protocol in our lab was to measure COD first to estimate BOD concentration, dilute samples accordingly, and then test 5 different volumes for each sample. This method consumed time and sometimes gene rated poor results when multiple or all dilutions failed the quality control criteria for dissolved oxygen (DO) depletion. A new procedure without measuring COD was developed to accurately determine BOD dilutions. First, historical data was used to generate a linear equation between the milligrams (mg) of BOD added in the sample and the resulted DO depletion (mg/L). Second, DO depletion criteria established by Standard Methods (5210B) was used to find an appropriate range of sample volumes that would cover all the potential BOD concentrations of the samples. The results obtained in the past two years using this new procedure demonstrate that it significantly improved data quality, preparation efficiency, and reduced incident s of failed BOD analysis. The approach and concepts developed here can be used in any laboratory that conducts BOD analysis by standard methods for samples collected from consistent sites.
