Hawaiʻi Wai Ola’s biannual data analysis report and water quality report cards present a cumulative analysis of all coastal water quality data collected across our monitoring network to date. Raw data are compiled, quality-controlled, and analyzed to identify spatial and temporal patterns, long-term trends, and areas of concern. The data analysis report provides a comprehensive synthesis of results across indicators and sites, while the water quality report cards translate those findings into clear, accessible summaries by community. All reports are updated twice per year as new data are collected and incorporated.
