attribute	NC_GLOBAL	summary	String	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.
