Water quality in streams of National Park of American Samoa: Summary report 2009–2011

Raikow DF and Farahi AC. 2015. Water quality in streams of National Park of American Samoa: Summary report 2009–2011. Natural Resource Data Series. NPS/NPSA/NRDS—2015/753. National Park Service. Fort Collins, Colorado

This Natural Resource Data Series Report (NRDS) presents data collected from Amalau Stream, Fagatuitui Stream, and Leafu Stream on the island of Tutuila, and Laufuti Stream on the island of Tau, National Park of American Samoa, in American Samoa. This is a summary or “data report” as described in the Water Quality Vital Signs Monitoring Protocol for the Pacific Island Network Version 1.0, Natural Resource Report NPS/PACN/NRR-2011/418. This report is restricted to data presentation and limited description. The data presented in this report will be analyzed for the establishment of expected parameter value ranges and long-term trends in future reports published in the NPS Natural Resource Report (NRR) series. Lower concentrations of dissolved nutrients observed in Laufuti pools as compared to downstream flowing portions of Laufuti stream were consistent with hydrological conditions. Differences between parameter values measured in Amalau Stream forest and village sites were subtle. TDN measurements appear higher in downstream Leafu Stream village sites compared to upstream forest sites. Turbidity slightly exceeded the published water quality limit once in Fagatuitui Stream in 2010, but sampling was limited to times of low flow due to safety concerns.
