Hui O Ka Wai Ola Water Quality Data

The goal of the Hui O Ka Wai Ola (Association Of The Living Waters) citizen-science based water quality program is to increase the capacity for monitoring water quality in Maui (2016-) and Lanai (2023-) coastal waters by generating reliable data to assess long-term water-quality conditions and detect temporal trends. These data augment the data produced by the Hawaii Department of Health (DOH) Clean Water Branch (CWB) beach monitoring program.

Data are collected and analyzed every two or three weeks for physical and chemical parameters, including ocean salinity, pH, temperature, organic nutrients (nitrogen and phosphorous compounds), dissolved oxygen (DO), and total suspended sediment (TSS). Some water samples are immediately tested at mobile labs while others are processed for testing at University of Hawaii and/or other labs.
acknowledgement=The Pacific Islands Ocean Observing System (PacIOOS) is funded through the National Oceanic and Atmospheric Administration (NOAA) as a Regional Association within the U.S. Integrated Ocean Observing System (IOOS). PacIOOS is coordinated by the University of Hawaii School of Ocean and Earth Science and Technology (SOEST). Hui O Ka Wai Ola is a partnership between The Nature Conservancy (TNC) Hawaii, Maui Nui Marine Resource Council, and West Maui Ridge to Reef (R2R) Initiative and supported by NOAA Coral Reef Conservation Program, National Fish and Wildlife Foundation (NFWF), Lahainaluna High School, Maui County, and North Beach-West Maui Benefit Fund, Inc.

Hui O Ka Wai Ola（活水协会）基于公众科学的饮用水质量项目旨在通过生成可靠数据以评估长期水质状况并检测时间趋势，从而增强对茂宜（自2016年起）和拉奈（自2023年起）沿海水域的水质监测能力。这些数据丰富了夏威夷州卫生部门（DOH）清洁水分支（CWB）海滩监测计划所产生的数据。

项目定期每两周或三周收集和分析物理和化学参数，包括海洋盐度、pH值、温度、有机营养物质（氮和磷化合物）、溶解氧（DO）以及总悬浮固体（TSS）。部分水样在移动实验室现场测试，其余则送至夏威夷大学及其他实验室进行检测。

Hui O Ka Wai Ola是由大自然保护协会夏威夷分会、茂宜努伊海洋资源委员会以及西茂宜海岸至礁石（R2R）倡议共同发起，并得到NOAA珊瑚礁保护计划、国家鱼类和野生动物基金会（NFWF）、拉海纳卢纳高中、茂宜县以及北海滩-西茂宜利益基金会的支持。
