Hawaii Water Quality Blog

Weekly reports on advisories, bacteria levels, sewage spills, and stream conditions across every Hawaiian island — compiled from 6 data sources

Every week, we compile advisory data, bacteria test results, USGS stream readings, and sewage spill reports into a single report so you can see what is actually happening with Hawaii's ocean water. The DOH only tests 57 of 300+ beaches — we pull from additional sources to fill the gaps.
