Hui o ka Wai Ola Water Quality Data

This dataset is the quarterly report for the Hui o Ka Wai Ola citizen-science based water quality program. Included are physical and chemical data that were collected and analyzed every two or three weeks beginning from June 6, 2016 to March 31, 2025. New results will be posted as available.

The goal of the Hui o Ka Wai Ola program is to increase the capacity for monitoring water quality in Maui 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 Clean Water Branch beach monitoring program on Maui.
