This data package was created 2025-12-03 08:48:21 by NPSTORET and includes selected project, location, and result data. Data are from Russell N. Clayshulte's (University of Guam Water and Energy Research Institute of the Western Pacific) 1985 Technical Report #57 entitled "Historical Water Quality of PUAG Production Water Wells" which compiled, edited, placed in computer storage, and statistically analyzed the historical water quality data from production water wells, which was generated by the Public Utility Agency of Guam (PUAG) water laboratory. This historical data report was a single source document which covered late 1976 through December 1983. It assessed baseline water and short-term trends for both individual water wells and combined well series and augmented other groundwater reports and studies as a useful management tool for making decisions about the Northern Guam groundwater aquifer. Data contained in WAPA_NPSTORET_BE.ACCDB (NPSTORET back-end file) were filtered to include: Organization: - WAPA: War in the Pacific National Historical Park Project: - WAPA0013: Historical Water Quality of Public Utilities Agency of Guam's Production Water Wells Station: - Include Trip QC And All Station Visit Results Value Status: - Accepted or Certified (exported as Final) or Final The data package is organized into five data tables: - Projects.csv - describes the purpose and background of the monitoring efforts - Locations.csv - documents the attributes of the monitoring locations/stations - Results.csv - contains the field measurements, observations, and/or lab analyses for each sample/event/data grouping - HUC.csv - enumerates the domain of allowed values for 8-digit and 12-digit hydrologic unit codes utilized by the Locations data table - Characteristics.csv - enumerates the domain of characteristics available in NPSTORET to identify what was sampled, measured or observed in Results Period of record for filtered data is 1976-09-01 to 1983-06-24. This data package is a snapshot in time of one National Park Service project. The most current data for this project, which may be more or less extensive than that in this data package, can be found on the Water Quality Portal at: https://www.waterqualitydata.us/data/Result/search?project=WAPA0013&mimeType=csv&zip=yes&dataProfile=biological&providers=STORET
