There’s a new website providing results from state’s shoreline water quality monitoring program: https://www8.honolulu.gov/env/kailua-water-quality-data/
Want to stay up to date with water quality? You can sign up at this website to receive notifications when a beach advisory, beach notification, brown water advisory, sewage spill or permit exceedance is issued, or any water quality advisory is canceled. https://eha-cloud.doh.hawaii.gov/cwb/#!/landing
