Agat Sewage Treatment Plant: Impact of Secondary Treated Effluent on Guam Coastal Waters

This data package was created 2025-12-03 10:42:25 by NPSTORET and includes selected project, location, and result data. Data are from Roy T. Tsuda and Deborah A. Grosenbaugh's 1977 (University of Guam Water Resources Research Center) 1977 Technical Report #3 (Marine Laboratory Technical Report #42) entitled "Agat Sewage Treatment Plant: Impact of Secondary Treated Effluent on Guam Coastal Waters". This project addressed the need for a long-term study of the impact of a secondarily treated effluent on Guam shallow coastal waters to base future depth requirements on scientific observations of an existing sewage outfall.

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:
- WAPA0024: Agat Sewage Treatment Plant: Impact of Secondary Treated Effluent on Guam Coastal Waters
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 1975-05-01 to 1977-07-01. 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:
