  1. Status of Revising the CBP Guidelines for Sampling and Analysis Mary Ellen Ley, USGS/Chesapeake Bay Program March 21, 2012

  2. Why Revise CBP Guidance for Analytical Methods and QA? • Expanding Monitoring into Nontidal Waters • Need Documented Program Requirements • Consistent development of Participant SOPs • Comparable data among Participants • Basis of On-site Assessments • The Current Publication is Outdated • Based on tidal estuarine methods • Published in mid 1990’s!

  3. Work Since 1996 Publication • Chlorophyll method – revised, 1999 • Light Attenuation method – new, 2003 • CDOM method – new, 2005 • Chapter IV, Tidal Field Procedures – revised, 3/2008 • Chapter V, Nontidal Field Procedure – revised, 11/2008 • Chapter I, Introduction – revised, 12/2010 • Chapter II, Quality Assurance – draft rev. 1, 3/2012 • Chapter VI, Analytical Methods – draft rev. 1, 3/2012

  4. Chapter II Notes • Changes to “Quality Management” Section: • Moved QAPP & Lab Manual Guidance to Appendix A • Added language from CBPO grant guidance • Procedural Modifications Comparability Studies • DQOs for Field & Lab QC in Tables II.1 & II.3 • Moved Lab-related QC Items to Chapter II, Lab QA

  5. Chapter VI Notes • November and February meetings in Colonial Beach • Section B. Definitions & Terms – new • Section C. Laboratory QA/QC – expanded • Preservation Table VI.1 – added nontidal • Sample Receiving/Storage, Support Equipment and Control Charts – from Ch. 2 • Calibration Requirements – refined, clarified • Outstanding Issues – Refer to Draft

  6. Still Needed for Final Publication • Chapter III. Data Management • Parameter Relationship Chart – species of N, P, C, SS • A New Title? • Other Suggestions?
