About this file

This is a Water Quality Data Review Checklist document developed by the State of Alaska, Department of Environmental Conservation (DEC), Division of Water, for quality assurance and quality control procedures related to water quality monitoring projects. The checklist provides a structured framework for reviewing raw data, field measurements, laboratory results, and database entries throughout multiple stages of a water quality monitoring project. The document is designed to be completed by project managers, secondary reviewers, QA officers, and data management leads, with each reviewer documenting the completion date and responsible party for each review step. The checklist encompasses pre-database reviews during and after field seasons, database preparation and import procedures, provisional and corrected data reviews, and final QA assessments before data is submitted to the Ambient Water Quality Monitoring System (AWQMS). Key review areas include verification that projects followed the Quality Assurance Project Plan (QAPP), assessment of data completeness against established goals, evaluation of field duplicate and blank samples with relative percent difference (RPD) calculations, verification of instrument calibration and performance, review of analytical laboratory reports and chain of custody documentation, and validation that all data fields in the AWQMS database are accurately populated with appropriate metadata.

The checklist serves as a quality assurance tool applicable to the RFP 18-820-26 contract for Tongass Narrows water quality sampling, which requires contractors to manage data using DEC-provided templates compatible with AWQMS. The document includes detailed yes-or-no questions with supporting note sections to document findings, discrepancies, rejections, and any data concerns requiring QA officer consultation. Review areas specifically address preservation and hold time requirements, detection limits, result qualifiers, media types, monitoring location metadata including latitude and longitude coordinates, time zone consistency (noting Alaska Daylight Time considerations), and the range of result values relative to expected environmental conditions. The checklist is designed to be iteratively completed, with project managers and secondary reviewers conducting repeat reviews until no errors are identified before final submission to the QA officer and data management lead for approval and project status change to final.

Data Review Checklist Pre-Database

During the field season, review raw data files (EDDs, instrument records) as they are received. Document changes and corrections to methods as needed.

Once all data is received, review for overall project success and conduct a detailed evaluation of field notes, in-situ field, and analytical results. Filter and sort raw data files to answer the following questions for all results. Include notes in this checklist as well as a supporting excel file with calculations and summary tables for all QA calculations. Document all data that fails QA and provide justification for any rejected results.

Database Prep

Add project to AWQMS database including QAPP and any supplemental data not part of import. Add monitoring locations to AWQMS database and associate monitoring locations with project. Develop import configuration file for Activities and Results. Copy raw data into import file and review for accuracy and completeness. Filter and sort import data file to review and correct any errors. Upload raw data in import file as “Provisional” status into AWQMS. Fix any import errors that arise. Repeat as necessary until all data is uploaded to AWQMS.

Complete
