Water quality in streams of Haleakala National Park: Summary report 2007–2011
Raikow DF and Farahi A. 2016. Water quality in streams of Haleakala National Park: Summary report 2007–2011. Natural Resource Data Series. NPS/PACN/NRDS—2016/1007. National Park Service. Fort Collins, Colorado
This Natural Resource Data Series Report (NRDS) presents data collected from Pipiwai Stream, Palikea Stream, and Alelele Stream in Haleakala National Park on the island of Maui, Hawaii, USA. 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. The purpose of collecting data on Vital Signs is to provide park managers information on current conditions and temporal trends in ecosystem health. Alelele Stream and Palikea Stream exceeded state water quality criteria for Nitrate + Nitrite is some years and seasons. Palikea Stream and Pipiwai Stream exceeded state water quality criteria for turbidity in 2007. Because dissolved nutrient concentrations do not include particulate nutrient concentrations, total nutrient concentrations, in which state criteria are written, will be higher in the stream. Thus, while dissolved nutrient levels in streams did not exceeded the state total phosphorus (TP) and total nitrogen (TN) criteria, the stream may in fact exceed state criteria at all times due to additional phosphorus in particulate form. Similar values in water quality parameters were observed in all three streams, with possible exception of slightly dissolved nitrogen (total and nitrate + nitrite) concentrations in Alelele Stream.
