Metals, PCBs, and PAHs in Sediments and Marine Organisms from Three Harbors on Guam

This data package was created 2025-12-03 07:35:38 by NPSTORET and includes selected project, location, and result data. Data are from the University of Guam's Water & Environmental Research Institute, which conducted a preliminary survey at the behest of the Guam Bureau of Planning - Guam Coastal Management Program, to check for heavy metals, PCBs, and PAHs in abiotic and biotic components from four harbors on the western side of Guam to investigate the degree of chemical contamination derived from human activities and the accompanying water quality changes.

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:
- WAPA0003: Metals, PCBs, and PAHs in Sediments and Marine Organisms from Three Harbors on 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 six 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
- Taxon.csv - enumerates the domain of taxa available in NPSTORET to identify the organism sampled for Results

Period of record for filtered data is 1997-05-16 to 1999-01-22. 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:
