Beach-water records include coastal samples, local notices and satellite observations. Chlorophyll and cloudy water can show parts of the marine environment, but they are not bacteria tests. Check what was actually measured at the beach.
Read the date and place on the test. Check what kind of water was tested and what the result means. A past test cannot tell you what is in the water here now. For a local warning, use the latest notice from the agency that covers the site.
Primary official marine/coastal quality source for Thailand MWQI and sampling-round context. Good for coastal status and pollution hotspots, not for same-day beach bacteria guarantees.
Access: PCD marine/coastal water-quality pages, MWQI summaries, and linked statistics/publications. Updates: Monthly / quarterly / annual depending survey cycle.
Primary official source for Thailand surface-water quality, WQI, and public water-quality service guidance. Use it for national river and lake status, not as a universal realtime API.
Access: PCD water-quality pages, publications, and linked national datasets for surface-water monitoring and WQI. Updates: Monthly / quarterly / annual depending dataset.
Representative automatic-station source for rivers such as Tha Chin, with parameters like temperature, pH, dissolved oxygen, and conductivity. Treat station coverage as partial, not nationwide realtime truth.
Access: Government Data Catalog dataset page with automatic-station resources and linked PCD catalog entry. Updates: Half-hourly observations at station level where resources remain current; catalog metadata on update.
Match any result to the named place, sample date, and type of water tested.
