This data package was created 2025-12-03 08:26:58 by NPSTORET and includes selected project, location, and result data. Data are from various sources compiled in John F. Mink and James A. Marsh's Technical Report No. 1 entitled "Groundwater Resources of Guam: Occurrence and Development" from September 1976 (reprinted May 1991) which was funded by the Public Utility Agency of Guam.
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: - WAPA0010: Groundwater Resources of Guam
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 1951-01-01 to 1967-01-01. 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:
