Justification:  The QAPP is being amended due to a change in consulting firms since the QAPP was approved.  The new consultants are Water Monitoring Solutions, Inc. (WMS) and Castilaw Environmental, LLC (CES) who are replacing HDR.

Additionally, Ammonia water samples will be analyzed by filtration rather than distillation starting with the third quarter of FY08 samples.

Detail of Changes: Changing consultants affects most sections of the QAPP.  The primary alteration of the approved QAPP is replacing HDR with WMS and CES.  The sections affected include the Title Page, List of Acronyms, Section A3 – Distribution List, A4 – Project/Task Organization, Figure A4.1 – Project Organization Chart, A9 – Documents and Records, Table A9.1 – Project Documents and Records, B10 – Data Management, C1 – Assessments and Response Actions, Table C1.1 – Assessments and Response Requirements, Appendix B, Appendix C – Field/Laboratory/Assessment Data Sheets, and Appendix D - Chain-Of-Custody Forms.

Analyzing Ammonia by filtration rather than distillation affects Table A7.1 - Measurement Performance Specifications by changing the Limit of Quantitation (LOQ) from 0.1 mg/L to 0.02 mg/L.  This change does not affect the storet code, method number, holding times, or other items.

Distribution:  QAPP Amendments/Revisions to Appendices will be distributed to all personnel on the distribution list maintained by the Planning Agency.

These changes will be incorporated into the QAPP document and TCEQ and the Northeast Texas Municipal Water District will acknowledge and accept these changes by signing this amendment.
